Boiler Feed Water Treatment is necessary to Produce quality steam on demand and depends on properly managed water treatment to control steam purity, deposits, and corrosion. Boiler performance, efficiency, and service life are direct products of selecting and controlling feedwater used in the boiler. When the solubility of a specific component in water is exceeded, scale or deposits develop. The boiler water must be sufficiently free of deposit-forming solids to allow rapid and efficient heat transfer and it must not be corrosive to the boiler metal. It is worth noting that, a badly treated steam boiler is a potential danger, so getting the feed water quality and boiler water chemistry correct is critical and that means using tried and tested boiler water treatment chemicals.
Boiler water treatment offers several benefits, including:
The base function of a cooling system is to remove heat from processes or equipment. Heat removed from one medium is transferred to another medium, or process fluid. Most often, the cooling medium is water. Cooling towers want water remedy to maintain operational expenses low and cooling efficiencies high. Without effective cooling water treatment, a cooling water system can suffer from scale formation, corrosion and fouling and may become a breeding ground for harmful bacteria. This reduces efficiency, shortens plant life and makes your operation unreliable and unsafe. Poor control can not only put your cooling process at risk, but can also incur huge cost in wasted energy, chemicals and water charges. To overcome these problems P&WC provides a comprehensive range of cooling water treatment products to keep your system operating safely and efficiently.
Raw water treatment system is a system made up of several individual technologies that address your specific raw water treatment needs.
The exact components of a raw water treatment system depend on the quality of water being drawn from in relation to the quality of water needed. Raw water treatment is a must in order to make water safe for consumption. It eliminates various contaminants like sediment, viruses, bacteria and other harmful substances from water sources with the help of filtration techniques. In raw water treatment systems use filtration techniques, sedimentation, coagulation-flocculation technologies, ultrafiltration and reverse osmosis to make water pure and safe.
Osmosis is a process of movement of solvents through a semi-permeable membrane from a region of lower solute concentration to higher solute concentration. On the contrary, diffusion does not require a semi-permeable membrane to occur and the molecules move from a region of higher concentration to lower concentration. Reverse osmosis as used in water treatment systems is a purification process through which water molecules pass through a porous membrane while leaving other molecules, presumably of contaminants, behind.
Industrial wastewater contains residues of potential chemical wastewater, sanitary waste water, technical waste water substances. This group of compounds is generally called “micropollutants” and existing conventional wastewater treatment plants based on biological treatment are capable of degrading or removing them. As a result, they are commonly discharged into water bodies, like rivers, causing harm to the fauna and flora of these habitats. Further, these receiving water bodies are often the source of water for drinking water production plants which would similarly pass the micropollutants. Therefore, there is an urgent need to implement new chemical treatment process to further treat effluent from conventional wastewater treatment plants. Processes commonly used in wastewater treatment include phase separation (such as sedimentation), biological and chemical processes (such as oxidation) or polishing.
