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

Activated Carbon INR   0 INR  0

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.

Industrial RO Plants INR   0 INR  0

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. Green Water Concepts engineers design and build tailor-made reverse osmosis plants on customs specifications. Our skid-mounted reverse osmosis plants range from tap water to brackish water and cover all type of application including drinking and process water. Green Water Concepts’ Reverse Osmosis plants are used to produce high-quality demineralised water. RO Plant is used extensively in the food and beverage industry (especially the brewing industry), pharmaceutical and the electronics industries. Green Water Concepts study the water chemistry and then select the most suitable membrane configuration in order to provide a plant which gives a high recovery rate. Further help is provided to the client to make use of, often by further treatment, of the reject water. The standard Green Water Concepts range of R O units utilizes the most modern membrane technology and consists of a modular design comprising of: • Skid-mounted epoxy-coated steel base • Spiral-wound membranes in high-pressure GRP vessels • Multi-stage high-pressure stainless steel feed pump • Control panel • Pre-filter • Pressure and flow gauges for feed, reject and permeate • Water quality indicator on conductivity alarm

Iron Removal Media - BIRM INR   0 INR  0

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.
