Water Treatment Plant Design: There are many types of ultrafiltration and water treatment plant design industries that use water in production process. At the end of production process water is contaminated and become useless unless it is treated. The contaminated water is called or effluent. The effluent is discharged to the nature by water treatment plant design the effluent should be treated for ecological existence. The effluent water treatment plant design may be chemical or biological. Initial investment of chemical process is low but running cost is more than in the biological treatment process that requires high establishment cost. Treatment procedure is selected considering customer’s affordability and availability of required land.

Sewage Sludge Method: The activated sewage sludge process, ulta filtration, nanofiltration, sewage sludge, electrocoagulation process are biological technique of wastewater treatment that is accomplished by a variable and mixed community of microorganisms in an aquatic environment. These microorganisms reach energy from carbonaceous organic matter in aerated wastewater for the production of new cells in a process known as synthesis during simultaneously releasing energy through the conversion of this organic matter into compounds that contain lower energy, such as carbon dioxide and water in a process called respiration. Activated Sludge Process: The consists by several functions such as solid liquid, sludge thickening, sludge de watering and sludge disposal. Activated Sludge Process The following equipments are manufactured by confident engineering for activated sludge process.

• Decanter • Sludge Thickener • Filter Press • Hydro Extractor • High Rate Solid Clarifier • Sludge Management Fluidized bed Reactor: eliminates hydrocarbons and BOD/COD in contaminated water. Oxygen transfer is used with a large protected biofilm attachment area for achieving high removal rates. Fluidized Bed Reactor Fluidized bed reactor is very easy to test influents and adjust biological parameters for maximum efficiency. The features of fluidized bet reactor is given below – • Fluidized bed reactor incorporates neutrally. • Fluidized bed reactor increases the effectiveness of the biological treatment process Nanofiltration for Salt Recover: Subsequently there are many raw materials are lost in the waste stream ending up in the environment as pollutants. When the other polluting components are treated with different treatment method mentioned in this article, the salt remains same in the effluent resulting in high TDS. Nanofiltration Advantages of Nano Filtration System: • Using nanofiltration and ultrafiltration technique 97% pure NaCl solution is obtained from the waste water. • Hardness less than 8 mg/L using nanofiltration process • Compliance of TDS value of less than 2000 mg/L is achieved as per Pollution control norms • Quicker Repeatability of Dyeing process using nanofiltration process • Improved repeatability of yyeing using filtration, Electrocoagulation Process: is the latest technology successfully installed in developing countries.
