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. The cartridges are of nominal rating with an efficiency of 88-90%. Sizes Length: 10” / 20” / 30” / 40” Outer Dia: 63mm ( Standard Cartridge) / 114mm (Big Blue of Jumbo Cartridge) Inner Dia: 27.5 mm Ends: DOE ( Double Open Ended) / SOE ( Single Open Ended)

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

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

Activated Carbon

Activated carbon, also called activated charcoal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. Those derived from coal and coke are referred as activated coal and activated coke respectively. Activated carbon works via a process called adsorption, whereby pollutant molecules in the fluid to be treated are trapped inside the pore structure of the carbon substrate. Carbon filtering is commonly used for water purification, in air purifiers and industrial gas processing, for example the removal of siloxanes and hydrogen sulfide from biogas. It is also used in a number of other applications, including respirator masks, the purification of sugarcane and in the recovery of precious metals, especially gold. It is also used in cigarette filters. Active charcoal carbon filters are most effective at removing chlorine, sediment, volatile organic compounds (VOCs), taste and odor from water. They are not effective at removing minerals, salts, and dissolved inorganic compounds. Typical particle sizes that can be removed by carbon filters range from 0.5 to 50 micrometres. The particle size will be used as part of the filter description. The efficacy of a carbon filter is also based upon the flow rate regulation. When the water is allowed to flow through the filter at a slower rate, the contaminants are exposed to the filter media for a longer amount of time. Green Water Concepts is one of the largest suppliers of activated carbon of different grades across Kerala.

Anthracite

Anthracite Filter Media are filtration materials for turbidity and SS removal. Since the specific gravity is lighter than that of Filter Sand, it is much used in combination with Filter Sand in dual-media filtration, to consist reverse grain layers after backwashing. In addition, because of high content carbon of this product, it has high resistance to various chemicals and high physical strength so that it is widely used for city and industrial water purification. Features of Anthracite Filter Media 1. High void percentage and much removal capacity of turbidity and SS.  In the “Single-medium filtration” treated by Filter Sand only, small particles are placed at upper part of layer, called as “Surface filtration” that turbidity and SS are caught at surface layer part mainly, and it results in less removal capacity of turbidity and SS. By use of Anthracite Filter Media of which the specific gravity is lighter than that of Filter Sand and even bigger particles can be placed on the Filter Sand, it is possible to enlarge the removal capacity of turbidity and SS as ideal “Dual-media filtration” in combination with Filter Sand and it is widely used in many water works in Japan. Since Anthracite Filter Media, rich angular and complicated in form, have high void percentage and large specific area, “Deep bed filtration” which is effective not only at the surface but also to the depth can be realized and it is also used with single and deep layer. From these features, the filtration will be effective by use of Anthracite Filter Media as follows. * Extending filter run length to lower washing water waste and improve treated water collection. * Possible to quicken filter run length to save space for installation of equipment. * Prevention of filtration blockage due to Synedra, Microcystin, etc. * Prevention of mad ball forming at the surface of sand layer. 2. Micro-flocs growing easily.  Since the grain has complicated form and angularities, suspended solids are retained in the inter granular spaces throughout the greater part of layer depth. After addition of coagulant, the water to be treated which has been sent out the filter without agitation is agitated and generates micro-flocs while it passes through the inter granular space. It results in improvement of treated water quality. * Improvement of treated water quality. 3. Easy change from single-medium filtration (by use of Filter Sand) to dual-media filtration.  The washing method of Anthracite Filter Media is the same as that of Filter Sand. It is no need to install new washing equipment additionally in case of changing the existing filter from single-medium filtration by only use of Filter Sand to dual-media filtration by use of Anthracite Filter Media. It is possible to improve the filtration effect by removing a part of Filter Sand and fill up with Anthracite Filter Media there. * Improvement of filtration effect with reasonable budget. 4. High resistance to chemicals  Since Anthracite Filter Media of good quality contains less impurities and much carbon and it is not dissolved in acidic and alkaline water, it is suitable as filter medium and also used in the chemical industry for the filtration of brine in soda manufacturers. * Possible to use with various chemicals. 5. Being used as a carrier for bio film treatment.  Since Anthracite Filter Media have high void percentage and large specific area, bio film is easily formed on them. The medium is the most suitable not only for physical filtration but also as a carrier for bio film treatment. * High effect as a carrier for bio film treatment.
