Technologies and products, we offer:

  • Mechanical filtration

Iron removal filter

Iron removal filter

Iron is removed from water by processes of aeration and filtration. Iron removal is based on the precipitation of dissolved iron (Fe2+) into the oxidized form (Fe3+) and separation.

Necessary data for customized design includes following parameters: water analysis (pH, Iron, Manganese & TDS etc.), water pressure, required water volume per hour, peak water demand per hour.

Application fields: drinking water, boiler water, cooling water, industrial process water.

Activated carbon filter

Activated carbon filter

Carbon filter filled with activated carbon removes chlorine, sediments and volatile organic compounds (VOC) by the process of adsorbtion. Filter ‘s media adsorbs or reacts with a pollutant molecule then filtered water is drained out.

Application fields: drinking water, boiler water, cooling water, industrial process water.

Anthracite/ sand filter

Sand filter

Sand filtration is physical water purification method. Water flows through a sand bed. Particles are removed through a physical filtering process. Sand filtration is a highly effective method to remove turbidity. There are two types of sand filters: the gravity and pressure types.

Application fields: drinking water, cooling water, industrial process water.

  • Ion exchange

Softening plant

Softening plant

Softener uses ion exchange resin to exchange calcium and magnesium for sodium.  Water is passed through the resin, the calcium and magnesium ions in the water replace with the sodium ions. The resin is regenerated with a highly concentrated sodium chloride solution.

Softeners can be with a wide range of configurations including tank construction, single, double and triple unit arrangements, piping etc.  Necessary data for customized design includes following parameters: flow rate of water to be treated, hardness of water.

Application fields: drinking water, boiler water, cooling water, industrial process water.

Dealkalizer

Dealkalizer

Dealkalizer reduces the bicarbonate content and the hardness by using ion exchange process.  Dealkalizer contains strong base anion exchange resin that exchanges chloride (the Cl ion of the NaCl) for carbonate and bicarbonate. Water passes through the anion resin, the carbonate, bicarbonate and sulphate ions are exchanged for chloride ions.

Application fields: drinking water, boiler water, cooling water, industrial process water.

Demineralization plant

Demineralization plant

Demineralization is the process of mineral salts removal from water. In this type of plant ion exchange process is used. In a demineralizer the water first passes through a cation column in which the cations in the water are exchanged for hydrogen ions, H+. Then the water passes through the anion column in which the anions of the water are removed by exchange for hydroxide ions, OH . When the plant capacity has been exhausted, the cation column is regenerated with hydrochloric acid and the anion column with sodium hydroxide.

Application fields: drinking water, boiler water, cooling water, industrial process water.

Selective ions removal plant

Selective ions removal plant

Ion exchange resins can be used to remove selectively ions from water. Some contaminants are not easy to remove by conventional ion exchange resins. The specific resins are used for the selective contaminants removal. Selective resins are used for the removal of chromate, lead, nickel, nitrate, boron, cadmium, mercury and other heavy metals.

Application fields: drinking water, industrial process water.

  • Disinfection

UV disinfection system

UV disinfection system

UV lamps emit ultraviolet light of a particular wavelength that has the ability, based on their length, to destroy microorganism ‘s cells. In the UV disinfection process, water is purified as it runs through a chamber that contains a special UV- producing lamp. As the water flows through the lamp, the microbes in the water receive a lethal dose of UV light. UV disinfection is effective, destroying 99.99 percent of harmful microorganisms without adding any chemicals to water.

Application fields: drinking water, industrial process water.

Ozone generator

Ozone generator

Ozonation is a chemical water treatment process based on the infusion of ozone into water. Ozone is an excellent disinfectant with the superior ability to kill viruses and biological contaminants found in water. It is also a very powerful oxidant that can oxidize metals in water such as manganese, iron and sulphur into insoluble particles, aiding in their filtration and removal from water. The treatment of water with ozone has a wide range of applications.

Application fields: drinking water, industrial process water.

  • Membrane technologies

Reverse osmosis plant (RO)

Reverse osmosis plant (RO)

Reverse osmosis (RO) is a highly effective water treatment process for reducing up to 99% of dissolved mineral salts, organics, and other particles by forcing water under pressure through a semi-permeable membrane. A reverse osmosis water system is induced by applying pressure with a pump to a solution with a high concentration of dissolved solids, causing water from the concentrated solution to pass through the membrane. This water is referred to as product water. Dissolved solids do not pass through the membrane; they are continually flushed to drain as waste water. This flushing action also keeps the membrane surface from fouling or scaling.

Application fields: drinking water, boiler water, cooling water, industrial process water, waste water.

Ultrafiltration plant (UF)

Ultrafiltration plant (UF)

Ultrafiltration (UF) is used to remove turbidity, suspended solids and organic substances. Ultrafiltration is the most effective technological process for water clarification or feed water preparation for nanofiltration and reverse osmosis. Pressured water flows through the ultrafiltration membrane but the suspended solids remain on its surface. Due to the small size of the membrane pores all suspended solids and microorganisms are effectively removed out of the water.  Ultrafiltration is one of the best methods for drinking water purification. Ultrafiltration is considered more effective as compared to traditional water filtration.

Application fields: drinking water, boiler water, cooling water, industrial process water.

Nanofiltration plant (NF)

Nanofiltration plant (NF)

Nanofiltration plants are used for reduction of organic matter, colour, sulphate, chloride, fluoride, bacteria, and virus. The operating range of nanofiltration lies between that of reverse osmosis and ultrafiltration. Nanofiltration, which is a membrane technology, is typically used for the treatment of drinking water and process water.

Application fields: drinking water, boiler water, cooling water, industrial process water, waste water.

  • Electrodeionization plant (EDI)

Electrodeionization plant (EDI)

Electrodeionization plant (EDI)

Electrodeionization (EDI) process uses resin, electricity, and ion exchange membranes to deionize water by separating the impurities from it. Electrodeionization (EDI) is a process by which an electric field is used to remove ions and polar species from the water stream. Usually, EDI plant is used after RO for polishing of demineralized water to obtain low levels of conductivity and silica.

Application fields: cooling water, industrial process water, waste water.

  • Containerized water treatment plant
