Can we become self-sufficient in water? – 2 Case Studies to support.
When we were planning for Hotel fifteen years back, I had the idea of reusing the sewage water. At that time, the cost of treatment was very high, and the recovery also was significantly less. Fast forward, I had no idea in my wildest dreams that I would be putting up a Sewage treatment plant for our family-run hotel in Palladam. Palladam is a small town near the famous Tirupur known for its banian manufacturing. Palladam is an arid area with significantly less rainfall, and the source of drinking water is from the Government and water tankers.
6 Usages of treated water – 3 domestic usage and commercial usage
In places where there are water shortages, treatment plants are the best option. The treated water is the most reliable and consistent source of water. The reason is that the treated water is under the user's control, unlike other water sources that are not in anybody's control, making it unreliable. In those places, sewage treatment plants can be a permanent solution. Proper treatment can recover more than 95% - 98% of the water and reuse them.
Sludge is the residue accumulated in the sewage treatment plants. Sludge is three forms solid, semisolid, or slurry residual material produced as a by-product of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge. Primary sludge is generated from chemical precipitation, sedimentation, and other primary processes, whereas secondary sludge is the activated waste biomass resulting from biological treatments.
Design Approach for Sewage Treatment Plant: A Case Study on STP on a Private Textile company, Kamanaickenpalayam, Tamilnadu.
The project details the study of domestic wastewater collected at Sahana Clothing Company Private Limited, Kamanaickenpalayam. This study focuses on the sewage generation in the above-mentioned location and modification of conventional sewage treatment plants by introducing OxyO technology. The total sewage generated was estimated at 150 KLD per day, considering the total population in the industry. The sample water collected from the conventional sewage treatment plant and characterization for the same has been done. The result has been provided (pH, Total suspended solids, Ammonia, Nitrate, COD & BOD).
4 Steps to handle & prevent overflow Problems in a sewage treatment plant
The primary role of a sewage treatment plant is to treat the sewage water. From our observations, we have seen plants not performing this role, and also, the fundamental part of holding the influx water does not happen. Sometimes the water overflows because the tanks are undersized or the people have increased over time. Whatever the reason, the problem needs to be solved immediately, and the association or management has to find a permanent solution.
Nowadays people, in general, have good knowledge of wastewater and sewage, thanks to Google. They do more research than those who are in the field. It creates more confusion rather than giving clarity. So in this post, I would like to share a few myths in the hope that they provide some clarity to sewage treatment plants and help you make better decisions.
