Treatment of Waste or Sewage Water

Packaged sewage treatment plant is a factory prefabricated method to treat waste water with implementation of aerobic process. It uses various processes and technologies to treat waste water. Some of these are Clarification, disinfection, membrane bioreactor, extended aeration, sludge digestion, tertiary separation, nitrification, flow equalization, oil/water separation, IFAS, and moving bed bioreactor. The final effluent after the treatment is released in the streams, rivers etc. Also, the treated non potable water is put to use in industries, agriculture, artificial recharge etc. In this way this water promotes aquaculture and agricultural production.

Things you should know

The size of tank and internal flow rate in a packaged sewage treatment plant can be tailored according to the requirement. In order to meet effluent requirement or particular site condition pre and post filtration or other treatment systems can be added. The packaged sewage treatment plant system is self-contained, pre-fabricated and compact which uses extended aeration process. These plants are uniquely implemented in households, complexes, hotels, resorts, military bases and camps. As these are pre-fabricated and pre-engineered structures/plants, the cost is low. The plant is user friendly, operable and easy to maintain.
The widely known RO system is based on the principle of Reverse Osmosis. This process is also termed as hyper- filtration. Reverse osmosis finely removes pollutants, impurities, volatile organic materials from the water. This makes the water appropriate for purpose of drinking and other industrial and commercial applications. The reverse osmosis plant suppliers also attach water softeners in the advanced models.

The process of purification of water works in stages. In first stage, sediments, dirt and other physical particles are removed. Then carbon filter eliminates the organics, smell and odor from the water. The cellophane like membranes separates the contaminated unpurified water from purified water. When pressure is applied to the concentrated flank of the membrane, the purified water is pushed towards the diluted side. Simultaneously the unwanted impurities present in the concentrated water are washed away in the rejected water. In order to remove the particles which do not pass through the membrane`s pores, RO behaves like an ultra-filter. At last the anti-bacteria activated carbon filter improves the taste of the treated water.


The reverse osmosis plant suppliers can improve reliability and performance of the reverse osmosis plant by carefully selecting and applying advanced treatment chemicals. This minimizes the problem of corrosion and scaling. The reverse osmosis plant suppliers should also carefully choose the membrane materials. Some of the common ones are TFC, CTA, SPS, CA etc.
