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.

Water Softener - Aqua Conditioner

Aqua Conditioners Technology The Aqua Conditioners technology is unique because it: Prevents scale & also breaks down existing scale – without salts, chemicals or electricity Provides an endless supply of ‘softened’ water without further cost or maintenance What is a Aqua Conditioner system? According to some very narrow definitions, a ‘water-softener’ changes hard water into the soft water only with the removal of calcium from the water with sodium carbonate. This means the Aqua Conditioners unit is not technically a water softener as it does not add chemicals or remove any minerals from the water flow. However, it does turn ‘hard water‘ into ‘soft water’ as characteristics of the calcium molecules changes so that it does not drop out and cling to other surfaces. The Aqua Conditioners device prevents scale from forming by neutralizing the scale producing properties of the minerals in hard water. This means the neutralized mineral particles will flow freely through the system without sticking to the surfaces. What does the Aqua Conditioners technology do? The technology is designed to protect plumbing systems and other surfaces from the negative effects of hard water minerals. The scale and residue that usually sticks to pipes, valves and other surfaces is prevented from forming by changing the hard minerals in the water into inactive microscopic particles. These inactive mineral particles stay suspended in the water (much like minerals are suspended in milk) and flow freely, unable to stick to surfaces. Most importantly, unlike hard water minerals, if the inactive mineral particles occasionally drop out of suspension they can easily be washed or wiped away without the use of caustic chemicals. How does a Aqua Conditioners work? The unit is installed directly on your water line. It has at its core a non-sacrificial, catalytic converter that is non-ferrous, resists rusting and corrosion, and is totally non-toxic and ecologically safe. The unit requires no salt, no resins, no electricity, no magnets, no back washing and no maintenance. Using a unique combination of metals within the alloy core plus the principle of turbulence (the Venturi effect), the water flow is forced through the Aqua Conditioners unit where an electro-chemical catalytic reaction occurs. During this reaction, electrons are transferred between molecules, completing missing electrons and so new mineral compounds are formed. The electro-physical changes in the minerals neutralize their scale producing properties. The result is that previously ‘hard’ minerals are changed from being large molecules into inactive, microscopic mineral particles. The Chemistry Blended in a specialized foundry process, each alloy core is made up of a number of dissimilar metals scientifically selected from the anode and cathode galvanic scale. The alloy is not a sacrificial anode (ie; does not need replacement). On contact with water thousands of intense galvanic electrochemical reactions occur along the length of the alloy core. Minerals are attracted to these galvanic sites as they flow through the system. The electrical charge or zeta potential of the minerals in the water is reduced allowing the minerals to aggregate and form nano-sized colloids which remain in suspension rather than precipitate on pipes and associated equipment. Zeta potential is considered to be the electric potential of the minerals in the water. Aqua Conditioners lowers the Zeta potential of water by a factor of almost 2.

Iron Removal Media - Green Sand

Manganese greensand is a purple-black filter media used for removing soluble iron, manganese and hydrogen sulfide from well water supplies through oxidation and filtration. It also has the capacity of removing radium and arsenic. It is processed from the mineral glauconite that is zeolite. Using iron exchange properties of this natural zeolite, a manganese dioxide coating is deposited on the surface of the glauconite grains. The manganese dioxide acts as a catalyst in the oxidation-reduction reaction of iron and manganese. The media can be used in two methods of operations: continuous regeneration (CR) and intermittent regeneration (IR). Soluble iron and manganese are oxidized and precipitated by contact with higher oxides of manganese on the greensand granules. The hydrogen sulfide is reduced by oxidation to an insoluble sulfur precipitate. Precipitates are then filtered and removed by backwashing. When the oxidizing capacity power of the Manganese Greensand bed is exhausted, the bed has to be regenerated with a weak potassium permanganate (KMnO4) solution thus restoring the oxidizing capacity of the bed. 1 ½ to 2 ounces of potassium permanganate, in solution, per cubic foot of Manganese Greensand is considered sufficient for normal regeneration. It is required to vigorously backwash and regenerates the bed when it is placed in service and before its oxidation capacity is totally exhausted. Operating the bed after oxidation capacity is exhausted will reduce its service life and may cause stain. ADVANTAGES of Green Sand • Iron reduction over wide pH range • Effective reduction of hydrogen sulfide in addition to iron and/or manganese • No harmful effects from a chlorine feed • Low attrition for long bed life Green Water Concepts is a major supplier of Green Sand in Kerala

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.

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.

Multi-port Valves

Valves which perform duties other than the two-way isolation, control and check are classified under the category of special purpose valves. Multiport valve is categorized as a special purpose valve. The multi-port valve on certain services reduces the time for operating and the overall cost. Multi-port ball valves are typically used in industrial fluid distribution applications., water and wastewater treatment systems. They can be used to mix two different fluids or to divert the flow of fluid from one direction to another. Other applications include use as sampling valves and drainage valves. The ball design in a multi-port ball valve usually has one of two common configurations, the “L” port or the “T” port. Some manufacturers such as Hayward Flow Control have as many as four ball configurations. Green Water Concepts is the dealer of multi-port valves of well-known brands like Midas, Initiative etc.
