Waste Water Treatment Plant, STP, ETP

We provides special type effluent treatment plants for PAINT industry.Paints generally consist of organic and inorganic pigments and dyestuffs, extenders, cellulosic and non-cellulosic thickeners, latexes, emulsifying agents, anti foaming agents, preservatives, solvents and coalescing agents. Wastewater is generated primarily due to cleaning operations of mixers, reactors, blenders, packing machines and floors. Then, and due to the varying degree of chemicals used, the wastewater contains appreciable concentrations of carbon (biological oxygen demand (BOD) or chemical oxygen demand (COD)), suspended solids, toxic compounds and colour The discharge of such wastewater into the environment impedes light penetration, damages the quality of the receiving streams and may be toxic to treatment processes, to food chain organisms and to aquatic life. Paint wastewaters International Journal of Science and Technology, The paint wastewater must be needed to discharge after treatment due to legal restrictions in organized industrial zone and environment conservation. Wide ranges of wastewater treatment techniques have been tested. Coagulation-flocculation is widely used for wastewater treatment, as it is efficient and simple to operate In addition, the process can be directly applied without being affected by the toxicity in the wastewaters. In this process, many factors can influence its efficiency, such as the type and dosage of coagulant/flocculant etc. Optimization of these factors may significantly increase the process efficiency. However, the performance of coagulation process may be poor and may result in treated wastewaters whose characteristics do not meet effluent standards. Consequently, a further treatment is necessary. Combinations of chemical and biological methods are used usually for effective treatment of such industrial wastewaters, since it is difficult to obtain satisfactory results by using anyone of those methods alone. Paint wastewater contains toxic compounds and was considered as inhibiting bacterial development Then, in addition to chemical treatment, an appropriate biological technology is required with purification of plantation (reed bed system).
