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.

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 - 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. PHYSICAL PROPERTIES OF BIRM MEDIA • Color: Black • Bulk Density: 40-45 lbs./ cu. ft. • Mesh Size: 10 x 40 • Specific Gravity: 2.0 gm/cc • Effective Size: 0.48 mm • Uniformity Coefficient: 2.7 CONDITIONS FOR OPERATION OF BIRM MEDIA • Alkalinity should be greater than two times the combined sulfate and chloride concentration. • Maximum water temp: 100o F/38o C • Water pH range: 6.8-9.0 • Dissolved Oxygen (D.O.) content must be equal to at least 15% of the iron (or iron and manganese) content. • Bed depth: 30-36 in. • Freeboard: 50% of bed depth (min.) • Backwash rate: 10-12 gpm/sq. ft. • Backwash Bed Expansion: 20-40% of bed depth (min.) • Service flow rate: 3.5-5 gpm/sq. ft. intermittent flow rates and/or favorable local conditions may allow higher flow rates INFLUENT AND BACKWASH LIMITATIONS • Free chlorine concentration less than INFLUENT AND BACKWASH LIMITATIONS OF BIRM MEDIA • Free chlorine concentration less than 0.5 ppm • Hydrogen Sulfide should be removed prior to contact with Birm® media • Oil: None Present • Polyphosphates: None present

Filter Sand

Filter Sand is a properly graded and dried sand. It is designed to be used in swimming pool, water & waste water filtration systems, . This filter sand also features a tan color. Narrowly graded, clean, dry sand. . Rapid sand filtration is a purely physical water purification method. Rapid sand filters (RSF) provide rapid and efficient removal of relatively large suspended particles. Two types of RSF are typically used: rapid gravity and rapid pressure sand filters. Filtering water through a layer of fine sand is one of the oldest forms of filtration. Dirt particles in the water are trapped and held in the very small openings between the grains of sand. This process of coagulation enhances the filtering efficiency of sand in capturing very small dirt particles. High-rate sand filters have a filter rate of 15 to 20 gallons per minute per square foot of filter area. They also work on the basis of depth filtration. The dirt removed from the water is not collected on top of the sand bed, but is driven into the sand bed by the high velocity of the water. In a typical pool filter, the primary dirt load is confined to the top 2-4” of the sand bed. In a high-rate sand filter the dirt is collected through the total depth of the sand bed. Green Water Concepts India Pvt. Ltd is one of the largest suppliers of filter sands of different grades across Kerala.

Softener Filter

Water that does not form an immediate lather with soap is called hard water. Hardness of water is due to the presence of soluble calcium, magnesium or iron compounds. The most common compounds are calcium bicarbonate Ca (HCO3)2, magnesium bicarbonate Mg (HCO3)2, calcium sulphate CaSO4 and magnesium sulphate MgSO4. The addition of soap forms an insoluble scum. The scum consists of insoluble salts of these metals. Removal of these salts from the solution makes the water soft. Water that forms an immediate lather with soap is called soft water. Such water does not have dissolved salts of calcium, magnesium and iron. Types of Hardness: Depending upon the behavior of water towards soap, hardness is divided into two types. 1. Temporary hardness: Hardness of water due to the presence of soluble bicarbonates of calcium and Magnesium is called temporary hardness. When water containing dissolved carbon dioxide passes over solid carbonates (chalk or limestone deposits etc.), these compounds get dissolved in water. Rainwater and distilled water are always soft because they do not have dissolved (soluble) salts. 2. Permanent hardness: This is due to the presence of chlorides and sulphates of calcium and magnesium. Such a hardness can be removed by the addition of washing soda. This removes both the temporary and the permanent hardness of water. Problems with hard water The presence of certain metal ions in water causes a variety of problems. These ions interfere with the action of soaps. They also lead to build up of lime scale, which can foul plumbing, and galvanic corrosion. In industrial scale water softening plants, the effluent flow from re-generation process can precipitate scale that can interfere with sewerage systems. The slippery feeling experienced when using soap with soft water occurs because soaps tend to bind to fats in the surface layers of skin, making soap molecules difficult to remove by simple dilution. In contrast, in hard-water areas the rinse water contains calcium and/or magnesium ions which form insoluble salts, effectively removing the residual soap from the skin but potentially leaving a coating of insoluble stearates on tub and shower surfaces, commonly called soap scum. So it is very essential to remove the hardness of water which is known as softening of water. METHODS OF SOFTENING OF WATER Temporary hardness is removed in the following ways: Permanent hardness can be removed by the following methods: Practical means for softening water rely on ion-exchange polymers or reverse osmosis. Other approaches include precipitation methods and sequestration by the addition of chelating) agents. Devices that claim to use magnetism or electricity as a “water softening” technique are fraudulent. Ion-exchange resin Conventional water-softening appliances intended for household use depend on an ion-exchange resin in which hardness ions mainly Ca2+ and Mg2+ are exchanged for sodium ions. Ion exchange devices reduce the hardness by replacing magnesium and calcium (Mg2+ and Ca2+) with sodium or potassium ions (Na+ and K+).” Types of ion exchange materials Ion exchange resins are organic polymers containing anionic functional groups to which the di-cations (Ca++) bind more strongly than mono-cations (Na+). Inorganic materials called zeolites also exhibit ion-exchange properties. These minerals are widely used in laundry detergents. Resins are also available to remove carbonate, bi-carbonate and sulphate ions which are absorbed and hydroxide ions released from the resin. Regeneration of ion exchange resins When all the available Na+ ions have been replaced by calcium or magnesium ions, the resin must be re-charged by eluting the Ca2+ and Mg2+ ions using a solution of sodium chloride or sodium hydroxide depending on the type of resin used. For anionic resins, regeneration typically uses a solution of sodium hydroxide or potassium hydroxide. The waste waters eluted from the ion exchange column containing the unwanted calcium and magnesium salts are typically discharged to the sewerage system.
