UV System

WHAT IS UV DISINFECTION SYSTEM AND HOW DOES IT WORK? UV Disinfection System is an extremely effective way to combat microbial contamination in water. However, microbes have to be exposed to UV-C light in the proper amount in order to effectively disinfect the water. UV Disinfection Systems are used in many different applications ranging from the purification of drinking water in individual homes to disinfecting water supply of entire townships. UV treatment for water is recognized as the safer and more cost-effective way to disinfect water for industrial applications. UV sanitization is useful in almost any application where microbial free, safe and pure water is required; and where there is a chance of the water being contaminated before it reaches the final point of use. How Does UV Disinfection System Work? UV light disinfects by penetrating microorganisms and destroying their DNA. DNA plays an important role in organisms’ functions and reproduction hence destroying the DNA prevents the organism from being active and multiplying. This UV energy (wavelength of 240-280 nm) is also naturally found in sunlight in very small quantities. The same energy is produced in stronger intensities with help of high mercury discharge lamps, commonly known as UV lamps. No bacteria, viruses, molds or their spores can survive when exposed to the correct dose of UV light. Therefore UV is considered as the best solution for water sterilization. Industrial Applications of UV Disinfection System Ultraviolet disinfection system is not simply a lamp inside a pipe. The UV Reactor must be designed to ensure that all microbes receive sufficient exposure to the UV light (dose).Based on the hydraulic properties of water; the reactor needs to be optimized to guide the flow in a manner so as to maximize residence time and boost turbulence. Well designed UV systems are producing consistently exceptional results in the industrial applications. Few Examples : Food and Beverage – UV disinfection system can help to achieve quality of water as per specifications laid down by the FDA ( Food and Drug Administration ) Bio- Pharmaceutical – Water used in Pharmaceutical and healthcare products and for CIP (Cleaning in Place) must be free of chemicals like chlorine, ozone, and pathogens. Most pharmaceutical companies depend on UV systems for water disinfection. Cosmetics – Water that is free of microorganisms and toxins ensure quality and enhance the shelf life of cosmetics. UV Sterilization is the preferred choice for the cosmetic industry across the globe. Centralized Drinking Water – A UV system is an easy, affordable solution to ensure pure water in each and every tap of your home or office. Waste Water Disinfection and Reuse – To combat the problems of water scarcity and rising cost of fresh water, UV Disinfection can help by treating the waste water in the tertiary stage. UV systems that are specially designed for wastewater can thus disinfect wastewater so that the water can be reused for secondary purposes such as flushing and gardening. Swimming Pools – Traditionally, chlorine has been in use to ensure clean water in swimming pools. However, it is increasingly being known that with chemical disinfection, chemical reacts with many other organic matters to form hundreds of new chemicals which are harmful. While UV is recognized as safer and more cost effective way to disinfect swimming pools. Benefits of UV Disinfection System Natural – UV is nature’s way of purification. Environmentally Friendly – No Toxic by-products are formed during UV disinfection process Effective – All known microorganisms are susceptible to UV light Economical – Lowest operating cost amongst disinfection systems Safe& Chemical Free – No addition of chemicals hence no danger of overdosing Fast – It is In-contact purification therefore Instant Easy to Manage – Well designed systems like the Alfaa UV systems come with many advanced features like CFD (Computational Fluid Dynamics), high-efficiency electronic ballasts, and extremely precise UV intensity monitors which make them highly effective and hence easy to manage. Does a UV Disinfection System need periodic maintenance? There can be some cases where the water is not adequately pre-treated and turbidity levels are low. In such cases, routine inspection and cleaning can be carried out every 6 months. In the case of high turbidity and hardness, the cleaning frequency might need to be increased. Finally, the UV lamp has a limited life and must be replaced once it is exhausted. In the unlikely event of premature failure of the lamp, the monitoring circuit will provide the signal to advise replacement.

cartridge Filters

Cartridge filter can be surface or depth-type filter: depth-type filters capture particles and contaminant through the total thickness of the medium, while in surface filters (that are usually made of thin materials like papers, woven wire, cloths) particles are blocked on the surface of the filter. These systems work by pushing water from the pool into the tank. A skimmer collects the larger debris and the secondary basket catches anything that the first one may have missed. The water then passes through the polyester filters, and dirt gets stuck on the screen allowing for clean water to pass by.

Activated Filter Media - AFM

AFM® Activated Filter Media is a direct replacement for sand, doubling the performance of sand filters without the need of additional investments in infrastructure. AFM® resists biofouling, biocoagulation and transient wormhole channeling of unfiltered water and never needs to be recharged or replaced. AFM® is a highly engineered product manufactured from a specific glass type, processed to obtain the optimum particle size and shape. It is then exposed to a 3-step activation process to increase its surface area by up to 300 times for superior mechanical and electro-static filtration performance. AFM® benefits at a glance • ... more than doubles the performance of an existing filtration system • ... is not subject to biodynamic instability and will never allow untreated water to pass • ... substantially lowers chlorine oxidation demand • ... lowers backwash water demand by an average of 50% • ... is expected to last for the life of the filtration system • ... provides quick return on investment Excellent performance of AFM® in comparison with quartz sand and other glass filter media AFM® comes with important certifications such as NSF 50 (swimming pools) and 61 (drinking water), HACCP, UK DWI and others. AFM®has been independently tested by IFTS Institute de la Filtration et des Techniques Séparatives in France in 2014 and its superior performance over quartz sand and other glass filter media was confirmed and is documented in the 2014 IFTS Report available below. AFM® more than doubles the performance of a quartz sand filter and it performs multiple times better than all other glass filter media tested. What makes AFM® so effective? 1. Clean, carefully selected glass AFM® is only made from pure green and brown glass which have the necessary metal oxides to help make AFM® self-sterilising. 2. Ideal hydraulic properties The raw material is ground into the optimal grain size and shape that is crucial for the outstanding hydraulic characteristics of AFM®. No dangerous glass splinters are allowed to be present in the filter material. Our manufacturing process is ISO certified. 3. Activation process The AFM® activation process creates a mesoporous structure with a huge catalytic surface area. Sand has a surface area of 3,000 m2 per m3 but AFM® has a surface area up to 300 times greater for adsorption and catalytic reactions. Hydroxyl groups on the surface give AFM® a strong negative charge, known as the zeta potential, that attracts heavy metals and organic molecules. In the presence of small amounts of oxygen or oxidising agents, the catalytic surface generates free radicals that make AFM® self-sterilising.

Iron Removal Media - Purolite M

Purolite MZ10 Plus Purolite MZ10 Plus is an iron removal media that removes soluble iron, manganese, hydrogen sulfide, arsenic and radium from water supplies. In addition to its catalytic property, it also facilitates the redox reaction of iron and manganese. Purolite MZ10 Plus effectively removes iron, manganese and hydrogen sulfide from natural waters. It can even be used at high operating temperatures and differential pressures without breakdown of the media. Unlike other medias, it does not require extensive pre-conditioning. PUROLITE MZ 10 is a Manganese Zeolite, an oxidizing and filtering medium, prepared by processing glauconite, a natural product, better known as “greensand”. PUROLITE MZ 10 effectively removes from natural waters iron, manganese and hydrogen sulphide, which are of particular concern because very small amounts of any one in a water supply can seriously limit its usefulness. Water for industrial and domestic uses must be iron and manganese free. In many countries, for municipal use, iron content cannot exceed 0.2 ppm and manganese 0.05 ppm, but they should preferably be less than 0.05 and 0.02 ppm respectively. In certain industries like pulp and paper mills, tanneries and textile plants, dye houses and laundries, it is almost impossible to operate with iron or manganese bearing waters since they would produce objectionable stains, streaks, spots and off-colours on many manufactured products. Iron and manganese also foul ion exchange resins which necessitate their removal as pretreatment to most ion exchange processes. PUROLITE MZ 10 is a quite versatile product that, used in conjunction with potassium permanganate, thanks to its catalytic properties, can reduce iron and manganese in water supplies to extremely low levels. None of procedures such as aeration, chlorination and filtration can yield an effluent with the same quality as obtained with the use of PUROLITE MZ 10. PUROLITE MZ 10 has a few unique characteristics in addition to its catalytic property that provides the maximum utilization of the oxidizing agent used, such as potassium permanganate, chlorine or dissolved oxygen, which results in increasing both the rate and the completeness of the oxidation reaction. Its oxidation reduction buffered capacity, for instance, governs the length of the operating cycle on the discontinuous process and permits a safe and smooth operation when it applies to the continuous process. Just as ion exchange resins have the capacity to exchange ions, so PUROLITE MZ 10 has the capacity to exchange electrons. This means that it can oxidize iron or manganese until the supply of electrons becomes depleted. These electrons may be replaced continuously or discontinuously by the addition of an oxidizing chemical such as potassium permanganate. The nodular shape and the fine size of the granules, together with their ruggedness and durability, afford excellent filtration efficiency, even after years of continuous service. COMMISSIONING PROCEDURE • Backwash the PUROLITE MZ 10 bed with water at a minimum linear flow rate of 30 m/h (m3/h/m2) for 15 to 20 minutes or, if available, with air and water. • Regenerate the PUROLITE MZ10 bed with potassium permanganate using a regenerant level of 3 g of KMnO4 per litre of zeolite, slowly passing a 0.3% solution through the bed in 30 minutes. • Displace the regenerant solution with 1 BV of water in 30 minutes. • 4 Rinse with 5 to 6 BV of water at the service flow rate, check the absence of potassium permanganate in the effluent and start the service run. HOW PUROLITE MZ 10 WORKS PUROLITE MZ 10 is employed following two basic application techniques, the choice of which depends primarily on the level and relative amounts of iron and manganese existing in the water to be treated. When iron removal is the primary objective, generally the continuous technique is applied. On the other hand, when the removal of manganese is the primary goal, the discontinuous technique is employed. Mixed techniques can be used for large units when both iron and manganese must be reduced to very low levels. The reaction in the removal of manganese is that PUROLITE MZ 10 oxidizes the manganese salts in the water to a higher insoluble oxide and, at the same time, the higher oxides which constitute the Manganese Zeolite coating are reduced to a lower insoluble oxide. After a specified quantity of raw water has been treated, or, in other words, after the oxidation 3 capacity is exhausted, the PUROLITE MZ 10 bed is regenerated with potassium permanganate. This step returns all the lower manganese oxides to the higher oxides and the cycle begins again. A similar reaction occurs in the removal of iron, with the difference that the ferrous ions are turned into ferric hydroxides, which are then filtered out by the bed. While the discontinuous system involves periodic regenerations with potassium permanganate the continuous system requires constant addition of potassium permanganate and/or other oxidizing chemicals directly into the water ahead of the PUROLITE MZ 10 filter. The discontinuous process sequence is: backwash, regeneration with a dilute solution of potassium permanganate, rinse and return to service, all requiring about one hour. Treated water is recommended for backwashing unless the iron and manganese in the raw water are very low. To maintain the bed in a clean condition, occasional air-water washes are recommended. The continuous process sequence is: backwash, rinse, and return to service, all requiring about 20 minutes. When backwashing with treated water, this rinse may be unnecessary. HYDRAULIC CHARACTERISTICS Pressure drop of a fluid passing through a fixed bed of any granular filter medium is related to the service flow rate, and to the viscosity and the temperature of the fluid. Typical values of pressure drop for PUROLITE MZ 10 are found in the figure below. PUROLITE MZ 10 is a pretty heavy product and requires important backwash flow rates to expand the bed and free it up from any particulate matter (mostly iron hydroxides) filtered out during the service run. To be effective, the backwash flow rate must expand the bed by a minimum of 35 to 40% for 10 to 20 minutes or until the effluent is clear. The proper backwash flow rate can be determined using the figure below. Low pressure compressed air applied prior to backwash with water can help loosening the PUROLITE MZ 10 bed. THE DISCONTINUOUS PROCESS The discontinuous process shall be used when both iron and manganese need to be removed, or whenever a minimum residual manganese concentration in the treated water is to be guaranteed. PUROLITE MZ 10 is in this case regenerated with a fixed amount of potassium permanganate when the specified quantity of water has been treated. This technique is so simple, safe and effective that it is widely used for household applications as well as for large industrial water treatment units.

Water Softener Media – Indion 2250 – Na

What is water softening? Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water is more compatible with soap and extends the lifetime of plumbing. Water softening is usually achieved using lime softening or ion-exchange resins. What is the life of water softener resin? The average life of a water softener system is 10 to 15 years, but water softeners can last for up to 20 years. Discover how to go about getting a water softener system replaced with help from a master plumber in this free video on water softeners. How often should a water softener regenerate? With the hardness minerals trapped in the resin and removed from the water, the water becomes “soft”. Over time, water softener resins get completely covered with hardness minerals and need to be cleaned. That's when backwashing takes place– to make the system “regenerate” or ready to start the softening process again. Water Softener Resin: INDION 2250 Na is a controlled particle size, strongly acidic, unifunctional, cation exchange resin containing sulphonic acid groups. It is based on cross linked polystyrene and has a gel structure. The resin is extremely robust and has excellent physical and chemical properties. It is supplied moist in the sodium form. Application: INDION 2250 Na is used most widely in sodium form for water softening application and it can be used as a substitute for conventional cation resin. It can also be used in two-stage de-ionising as the cation exchanger in the hydrogen form with INDION GS 3000 Cl. Green Water Concepts is one of the dealers of softener resin in Kerala

Industrial RO Plants

Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property, that is driven by chemical potential differences of the solvent, a thermodynamic parameter. Reverse osmosis can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective", this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as solvent molecules) to pass freely. In the normal osmosis process, the solvent naturally moves from an area of low solute concentration (high water potential), through a membrane, to an area of high solute concentration (low water potential). The driving force for the movement of the solvent is the reduction in the free energy of the system when the difference in solvent concentration on either side of a membrane is reduced, generating osmotic pressure due to the solvent moving into the more concentrated solution. Applying an external pressure to reverse the natural flow of pure solvent, thus, is reverse osmosis. The process is similar to other membrane technology applications. However, key differences are found between reverse osmosis and filtration. The predominant removal mechanism in membrane filtration is straining, or size exclusion, so the process can theoretically achieve perfect efficiency regardless of parameters such as the solution's pressure and concentration. Reverse osmosis also involves diffusion, making the process dependent on pressure, flow rate, and other conditions. Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other effluent materials from the water molecules.

Iron Removal Media - BIRM

Clack Birm® is a granular filter media commonly used for the reduction of iron and/or manganese from water supplies. Birm® is an efficient and economical media for the reduction of dissolved iron and manganese compounds from raw water supplies. It may be used in either gravity fed or pressurized water treatment systems. Birm® acts as an insoluble catalyst to enhance the reaction between dissolved oxygen (D.O.) and the iron compounds. In ground waters the dissolved iron is usually in the ferrous bicarbonate state due to the excess of free carbon dioxide and is not filterable. Birm®, acting as a catalyst between the oxygen and the soluble iron compounds, enhances the oxidation reaction of Fe++ to Fe+++ and produces ferric hydroxide which precipitates and may be easily filtered. The physical characteristics of Birm® provide an excellent filter media which is easily cleaned by backwashing to remove the precipitant. Birm® is not consumed in the iron removal operation and therefore offers a tremendous economic advantage over many other iron removal methods. Other advantages of Birm® include; long material life with relatively low attrition loss, a wide temperature performance range and extremely high removal efficiency. Negligible labor costs are involved because Birm® does not require chemicals for regeneration, only periodic backwashing is required. When using Birm® for iron removal, it is necessary that the water: contain no oil or hydrogen sulfide, organic matter not to exceed 4-5 ppm, the D.O. content equal at least 15% of the iron content with a pH of 6.8 or more. If the influent water has a pH of less that 6.8, neutralizing additives such as Clack Corosex®, Calcite or soda ash may be used prior to the Birm® filter to raise the pH. A water having a low D.O. level may be pretreated by aeration. Additions of chemicals to influent or backwash water which contacts Birm® media may inhibit iron or manganese removal or may break down or coat Birm® media. Chlorination greatly reduces Birm®’s activity. High concentrations of chlorine compounds may deplete the catalytic coating. Polyphosphates are known to coat Birm® and reduce Birm®’s ability to remove iron or manganese. Before adding any chemical to the influent or backwash water, the chemical's compatibility with Birm® should be thoroughly tested. Clack Birm® may also be used for manganese reduction with the same dependability as iron removal. In these applications the water to be treated should have a pH of 8.0-9.0 for best results. If the water also contains iron, the pH should be below 8.5. High pH conditions may cause the formulation of colloidal iron which is very difficult to filter out. All other conditions remain the same for either manganese or iron removal. Advantages of BIRM Media • Under the proper conditions, no chemicals to purchase for maintenance. Regeneration not required. • Iron removal efficiency is extremely high. • Negligible labor cost: only periodic backwashing required. • Durable material with a long life and wide temperature range. • Weighs only 40-45 lbs./cu. ft.
