Abstract - Activated Sludge Treatment is a biological wastewater treatment process which speeds up waste decomposition by adding Activated sludge into wastewater, and the mixture is aerated and agitated for a specified amount of time there by allowing the activated sludge to settle out by sedimentation and is disposed of (wasted) or reused (returned to the aeration tank). It is to everyone’s.Read More

The recovery of biogas could offset the energy required by the entire treatment process, enabling energy-neutral or even energy-positive wastewater treatment. Although biogas can be utilized through combustion as fuel for heating or electric generation, this conventional technology suffers a few barriers, e.g., low energy efficiency, low carbon efficiency and heavy investment.Read More
What happens in a wastewater treatment plant is essentially the same as what occurs naturally in an ocean, lake, river or stream. The function of a wastewater treatment plant is to speed up this natural cleansing process. The practice of wastewater collection and treatment has been developed and perfected, using some of the most technically sound biological, physical, chemical and mechanical.Read More
