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.

Wound Polypropylene Micron Cartridge Filters

Wound Polypropylene Micron Cartridge Filters These are popular liquid filter cartridges that have a continuous, diagonally interlocking weave over a supporting core. The most popular media used for these filters is a polypropylene(PP) yarn over a PP supporting core. The winding provides tapered filter passages of controlled size and shape. The larger particles are trapped on the outer surface and form a pre-cake. The smaller particles are trapped within the torturous path of the winding. These filters work on the principle of depth filtration, offering a gradual rise in pressure drop across the life of the cartridge. Brand Hydrowound MMP is the largest manufacturer of the wound PP cartridges in India. The Hydrowound cartridges use the PP yarn manufactured by a superior technology. The yarn is fibrous and has about 40% higher air volume compared to conventional yarn. The filtration takes place by “absorption technology”. This provides for the advantages of (a) lower pressure drop (2) increased efficiency and (3) higher dirt holding capacity. Micron Rating MMP Hydrowound cartridges are offered in standard micron ratings of 0.5, 1, 5, 10, 25, 50, 75 and 100. On request, customised micron rating can also be provided.

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.

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.

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.
