PURE WATER TECHNOLOGY
Purified water is water that is mechanically filtered or processed to be cleaned for consumption. Distilled water and deionised (DI) water are the most common forms of purified water, but water can also be purified by other processes including reverse osmosis, carbon filtering, micro filtration, ultra filtration, ultraviolet oxidation, or electro dialysis. In recent decades, a combination of the above processes have come into use to produce water of such high purity that its trace contaminants are measured in parts per billion (PPB) or parts per trillion (PPT) or parts per million (PPM).
Purified water has many uses, largely in science and engineering laboratories and industries, and is produced in a range of purities.
We use a 5 stage filteration system to produce pure water
Sediment is any particulate matter that can be transported by fluid flow and which eventually is deposited as a layer of solid particles on the bed or bottom of a body of water or other liquid.Sedimentation is the deposition by settling of a suspended material.In a water plant these particles may be rust flakes from the water pipes, sand grains, small pieces of organic matter, clay particles, or any other small particles in the water supply.
A filter with granular activated carbon (GAC) is a proven option to remove certain chemicals, particularly organic chemicals, from water. GAC filters also can be used to remove chemicals that give objectionable odors or tastes to water such as hydrogen sulfide (rotten eggs odor) or chlorine.
Carbon filtering is a method of filtering that uses a bed of activated carbon to remove contaminants and impurities, using chemical absorption.
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.
40-40 Reverse Osmosis
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.
Mixed bed deionization
Mixed bed deionization is 50/50 mixture of cation and anion resin combined in a single ion exchange column. With proper pre-treatment, product water purified from a single pass through a mixed bed ion exchange column is the purest that can be made by humans. Most commonly, mixed bed demineralizers are used for final water polishing to clean the last few ions within water prior to use. Small mixed bed deionization units have no regeneration capability. Commercial mixed bed deionization units have elaborate internal water and regenerant distribution systems for regeneration. A control system operates pumps and valves for the regenerants of spent anions and cations resins within the ion exchange column. Each is regenerated separately, then remixed during the regeneration process. Because of the high quality of product water achieved, and because of the expense and difficulty of regeneration, mixed bed demineralizers are used only when the highest purity water is required.
