Wastewater Management in India

Image
  Wastewater Generation in India India generates a staggering 1.7 million tonnes of faecal waste a day. Official figures show that  78% of the sewage generated remains untreated  and is disposed of in rivers, groundwater or lakes. The  two main sources of water contamination are sewage and industrial waste.  With both the population of India and its industrial landscape increasing at a phenomenal speed, wastewater volume is also at an alarming rise. Adding to this is the  shrinking of freshwater sources  like rivers, wells, and groundwater. Effects of Increasing Wastewater Harmful effect on the river and marine life Lack of drinking water Overabundance of certain harmful chemicals in sources of water, some of which are chronic Adverse effect on groundwater Soil pollution Rise in chronic health conditions related to toxic chemicals like lead and mercury in all living creatures Rise of pollution in the coastal area The Legal Mechanism for Waste-water Reg...

HOW IS SLUDGE DEWATERING BENEFICIAL?

Image
Wastewater treatment has become a necessity for survival as the scarcity of water is on the rise and it could get worse in the near future. As humans are held responsible for contaminating the water resource and for risking the lives of future generations, procedures like sludge dewatering have become a common practice in almost all countries across the globe. What is sludge dewatering? Dewatering of sludges is the process of removing excess water from the sludge. Sludge is the byproduct of extracting slurry during the procedure of wastewater treatment.  Sludge dewatering  is usually done to make its disposal easier. With numerous processes like belt press, centrifuge/decanter, and filter press, dewatering of sludge can be done easily. According to studies, sludges contain a lot of water, making them heavier and costlier for disposal. The sludges obtained during the wastewater treatment from industries and municipals are separated into liquid and solid components. The liquid o...

How does a sewage treatment plant actually work?

Image
Each person uses an average of 120 litres of water per day.   This is used for a wide variety of purposes (body cleansing, cooking, flushing toilets, etc.). But what actually happens to the dirty water / waste water when it leaves our area of application? Waste water is drained through pipe systems and thus enters the public sewerage system. Here we differentiate between two types of drainage. In the  combined sewer system , domestic and commercial wastewater is fed into a sewer together with rainwater that accumulates on sealed surfaces (e.g. streets and roofs). The separate sewer system divides the media. Dirty water is fed into one sewer, surface water into another. Because of the low dirt load, the collected surface water is usually discharged into neighbouring waters (lakes or rivers). The wastewater and the combined sewer both end up at the treatment plant. Of course, in the case of combined sewer systems, the sewage treatment plant has more work to do, as all the surfac...

How Wastewater Treatment Works??

Image
No new water is ever created on earth. Humans are just   reusing the same water   that has been on the planet for millions of years. Since fresh water is a finite and limited resource, steps must be taken to insure that any water used by homes or industry is cleaned up, or treated before it is returned to the environment. Most sewage and wastewater goes through a three stage treatment process: primary treatment, secondary treatment, and tertiary treatment. This guide is intended to serve as an introduction to the different stages of wastewater treatment. Primary treatment After a pre-treatment phase where larger pieces of debris such as trash and tree branches are removed, wastewater goes through the primary treatment stage. In this stage, water flows through settling tanks where lower density substances such as oils, grease and some solid wastes are allowed to rise to the surface. Devices such as skimmers go across the surface of the water to remove the oils and solids that h...
