Comparison between Conventional ETP and ETP using Nanofiltration by Analyzing the Results of Chemical Industry as Per CPCB Norms

Abstract: Our mother nature has its own capacity of purifying the water but due to billions of population her capacity is reducing as the quality of waste water is becoming worst. Without the treatment of waste water it becomes troublesome for whole ecosystems as well as for the environment. Globally around 80% of waste water is being discharged in the natural streams without any proper treatment. If it continues likewise then the day is no longer when we starve for pure water at least for drinking purpose. Waste water treatment helps to keep the water in its purest form for reuse for various domestic as well as industrial purposes. Waste water treatment also helps to protect the ecosystem. There are various ways to treat the waste water such as rainwater harvesting, desalination, water location transfer, zero liquid discharge, water treatment plants etc. for the treatment of high amount of waste water from industries and municipal areas suitable water treatment plants are necessary. Generally the conventional treatment of water consists of 4 stages like preliminary, primary, secondary and tertiary treatment. But in some cases (like chemical, pharmaceutical, petroleum industries) advanced treatment is required which is known as quaternary water treatment. This process involves advanced oxidation and fine filtration. Each of these units has different capacity of removing different solids as the water passes through it successively and as an end result we get the clearer form of water than it?s before. This research also deals with the advanced membrane filtration technology like Nano-filtration where it can partially replaces RO and the comparison between the results obtained from conventional ETP and ETP by using Nano filtrations as advanced filtration technique which replaces sand and carbon filters.
