Water treatment General


Water treatment is, collectively, the industrial-scale processes that makes water more acceptable for an end-use, which may be drinking, industry, or medicine.   
Water treatment is unlike portable water purification that campers and other people in wilderness areas practice. Water treatment should remove existing water contaminants or so reduce their concentration that their water becomes fit for its desired end-use, which may be safely returning used water to the environment.

Ultra violet (UV) water purifier

Ultra violet (UV) water purifier:Ultraviolet light, at the germicidal wavelength of 253.7 nanometers, alters the genetic (DNA) material in cells so that bacteria, viruses, molds, algae and other microorganisms can no longer reproduce. The microorganisms are considered dead, and the risk of disease from them is eliminated.It is proven scientifically that 85% of child sickness and 65% of adult diseases are produced by water-borne viruses, bacteria and intestinal protozoa such as Cryptosporidium and Giardia. Inappropriate water treatment can lead to heath problems – hepatitis B, tuberculosis, meningitis, typhoid fever, trichomoniasis, and cholera, glaucoma, gastrointestinal pain, salmonella, poliovirus, and diarrhea

Commercial Ro System

Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove 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, a thermodynamic parameter. Reverse osmosis can remove many types of molecules and ions from solutions, 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 the solvent) to pass freely.

RO Boiler chemicals

Boiler feed water it  is an essential part of boiler operations. The feed water is put in to the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the feed water is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank. From this tank it then goes back to the steam drum to complete its cycle. The feed water is never open to the atmosphere. This cycle is known as a closed system or Rankine cycle.

Industrial reverse osmosis

The process of commercial and industrial reverse osmosis provides very high quality water for a variety of uses. From drinking water consumption to sea water desalination, reverse osmosis is widely used in homes and industry where high quality, low TDS water is required. Depending on the specific requirements, reverse osmosis (RO) commercial systems are available in many production capacities. For higher volume needs,

Dual media filter

 Dual media filters are used in places where the raw water contains suspended particles, turbidity and iron. Dual media filters provide very efficient particle removal under the conditions of high filtration rate. These filters use layers of anthracite and garnet particles as the filter medium, with filtration rate of 98% down to 2 microns.The dual media filters employ an automatic backwashing feature, which employs a combination of air and water to maintain unit efficiency

Pressure filter

Press or Pressure filters are used for treating wastewater in wastewater plants. Pressure filter functions by creating an extremely large pressure differential across the filter media.  There are different types of filtration media that are used in removing contaminants from the fluids. The popularly used media are sand, gravel, activated carbon, and other granular media.   Through pressure filtration, dry filter cake is produced from suspended solids or contaminants. While producing dry cake the mechanism also produces liquid filtrate with a high degree of clarity. There are different types of press or pressure filters like

Sand filter

Sand filter Sand Filters are used world over for water treatment. These filters are used in various industries for cleaning water. In sewage units, sand filters are used as a final polishing stage. In sand filters the residual suspended materials and bacteria are trapped by the sand. The sand filter also provides physical matrix for bacterial decomposition of nitrogenous material like ammonia and nitrates, into nitrogen gas. For different application there are different types of sand filters. Usually there are three types of sand filters used:Rapid (gravity) Sand Filters Upflow Sand Filter Slow Sand Filters 

Carbon filters

Carbon filters Carbon filters can remove most of the organic compounds, which cause aesthetic problems (taste and odor). The longer the filter remains in contact with water, the more effective it will be in removing the foreign matter. Some of the typical examples of carbon filters include faucet mounted, in line, line bypass, point of entry, pour through, and specialty filters. Faucet mounted filters are connected to the faucet directly. In line filters are placed under the sink on the supply line of cold water; it means that hot water is not filtered. Line bypass models are based on a separate faucet at the sink that supplies only filtered water. Water from the existing fixtures will stay on untreated. Point of entry (POE) systems feature a filter, which treats all water entering the home. These systems have also found to be useful in removing volatile organic compounds, which would otherwise disperse into the air. However, these systems are also the most expensive

Chemical dosing system

Chemical dosing system Aqua Enviro Care  has expanded and updated its range of powder handling systems so that they are ideally suited to the accurate discharging and metering of water and effluent treatment chemicals. As a result, we are able to help Waste Management companies comply with the Landfill Directive (EC), Chemical and Other Processing companies comply with the regulations covering the discharge of effluent into rivers and stream and Utility companies to meet their quality obligations in terms of domestic water supplies.A wide range of conveyors may be used to achieve very accurate dosing with rates as low as 1kg/hr. Providing an even and consistent  material flow, the Aqua Enviro Care systems can eliminate bridging of material and consequent starvation of the conveyor leading to the slurry tank.

Water Clarification

Water Clarification Clarifiers are used for the purpose of clarification of wastewater. Clarification is the widely accepted and the oldest used method in the effective treatment of water and wastewater. This operation includes removal of sediment, floating material and turbidity from raw wastewater.Water clarification process is not the one process but the combination of different processes. Large suspended solids get settle down by gravity. For non-settleable material removal is done through coagulation, sedimentation and flocculation. All these three processes are collectively called conventional clarification or the water clarification.
