Reverse Osmosis Plant
We have Reverse Osmosis (RO) plant to clean and purify water by removing salts and other impurities to improve the color, taste or properties of the water. RO plant can be used for purifying other fluids like ethanol, glycol, etc. Our plant is well equipped with all the instruments and required facilities to meet specific customer needs. The company prefers high quality Reverse Osmosis (RO) Membrane elements to ensure flawless operation. Reverse osmosis (RO) was the first cross flow membrane separation process to be widely commercialized. RO remove virtually all organic and inorganic compounds 90 to 99% of all ions. We have a large selection of reverse osmosis membranes to meet varying rejection requirements. The cross flow mode of filtration continuously sweeps the membrane surface clean of impurities, which allows for many hours of trouble free and continuous operation between chemical cleanings. It is more energy efficient as compared to heat driven purification (distillation) and more efficient than the strong chemicals required for ion exchange. In this process, no energy – intensive phase change is required. Pores in reverse osmosis membranes are so small they have not yet been resolved, even by the most advanced microscopic techniques. These are generally regarded to be in the 0.0001-micron range, four orders of magnitude smaller than the finest of the normal – flow particle filter. Reverse osmosis (RO) is a membrane technology with myriad applications, but most well-known for its use in desalination for drinking water production. Reverse osmosis water treatment allows passage for only small and weakly charged molecules, such as water. Undissociated acids, such as carbonic acid (H2CO3), can also easily pass through. Carbonic acid is part of the carbonate system and not a contaminant—it affects the pH of the product water. Sodium and chlorine, which only carry a single charge and are also small, can pass through the membrane but not quite as easily as water. Molecules that are larger and/or more strongly charged than sodium and chlorine are rejected altogether.
Iron Removal Plant
The Iron Removal Filters are designed to remove the Excess Iron content present in the feed water with minimum pressure drop. Most iron filtration systems operate on the principal of oxidizing the iron (oxidation) to convert it from a ferrous (dissolved or soluble) to a ferric or undissolved state. Iron removal plants can be based on different filtration media, depending on the iron and manganese concentration, the oxygen level, CO2 content and hardness of the water. Plant principle: First, air is injected in order to oxidize the iron. The oxidized iron will then precipitate on a sand filter. Determining what is in the water is the first step in treating and providing safe clean water. A chemical-free iron filter such as a Katalox system removes iron, manganese and hydrogen sulfide safely and effectively. Iron filters are designed to remove these contaminants from the water and flush them away. The Iron Removal Filters are designed to remove the Excess Iron content present in the feed water with minimum pressure drop. Most iron filtration systems operate on the principal of oxidizing the iron (oxidation) to convert it from a ferrous (dissolved or soluble) to a ferric or undissolved state.
Sodium bicarbonate is an ideal pH and alkalinity control agent for wastewater treatment. It provides a reserve buffering ability to help prevent upsets in the operating systems of secondary treatment plants that depend on microorganisms to digest organic wastes and control odor. Acids produced in the waste breakdown process, along with other conditions prevalent in treatment plants tend to lower pH. This alters the biological balance, and can result in bulking sludge, digester upset and the “rotten egg” or hydrogen sulfide odor that usually means trouble and expense for the plant. Because sodium bicarbonate is buffered, it cannot cause the pH overrun that harsh alkaline chemicals like lime, caustic soda and ammonia can. It can be slug-fed or added continuously to digesters at the operator’s discretion. In aerobic digestion systems, the optimum feed point is the return sludge line, or at the head of the aeration basin. Since low loading takes place at most wastewater treatment plants during the night, sodium bicarbonate is added in the late afternoon or early evening for best results. With anaerobic systems, it is recommended that product be applied in the wet well or scum pit on the sludge line leading to the digester. Sodium bicarbonate should be fed in a manner that promotes maximum distribution throughout the digester.
Manganese greensand is a purple-black filter media used for removal soluble iron, manganese and hydrogen sulfide from well water supplies. 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). Physical properties:

Treated SandIron and manganese occurs naturally in the groundwater, excess amounts of iron and manganese in groundwater can cause adverse heath effects, else can stain clothes, rusty taste, discolor plumbing fixtures and laundry. OXYCAT+ is a common inorganic chemical / iron media used to treat drinking water for iron, manganese and sulfur odors. It can be used as a disinfectant as well, keeping drinking water free of harmful bacteria. OXYCAT+ is an efficient and economical method of removing iron and manganese compounds from groundwater by process of gravity fed or pressurized water treatment systems. Oxycat+ acts as insoluble catalyst between the dissolved oxygen and soluble iron compounds, enhances the oxidation reaction of Fe++ to Fe+++ and produces ferric hydroxide which is precipitated as ferric hydroxide and easily removed it by backwashing process. OXYCAT+ also reduce manganese from groundwater while manganese is converted from a two-plus to a four-plus state. This reaction takes about five to 10 minutes in drinking water that has a pH at or above 7.00. Organic matter can cause unpleasant odors in drinking water. OXYCAT+ can be used to neutralize these smells and disinfect the drinking water at the same time.
Mno2 is highly used in the water treatment industry for softening hard water by the removal of soluble iron, manganese, hydrogen sulphide, arsenic and other soluble metals from water.

Wound Cartridge Filter
Wound Filter Cartridges are designed to meet the most demanding filtration application. They offer an economic, compact, easily installed and maintained filtration system for removal of particles from liquid. are manufactured using the latest winding technology which gives true graded density with denser layers inside and coarser layers outside. This produces superior depth filters with increased filtration capacity, longer service life and higher performance that reduces overall costs. These are processed into fibers of specific grades using the latest technology. After carding & spinning into roving they are wound into cartridges with cautiously controlled micron rating. From raw materials to finished products we are in control of the quality and filtration characteristics. They are appreciated due to its high dirt holding capacity and rugged construction that allows facing different applications in liquid and gas filtration. The quality of a wound filter cartridge hugely depends on the type of yarn that is used to make the filter. The material of the core and a controlled manufacturing mechanism that produces a precise micron rating also contribute.
