Activated Sludge Treatment Process – What Volume and Density Limits Are Ideal

[ad_1] The activated sludge treatment process is a long drawn out process. During different stages of this treatment the volume of the dissolved and suspended particles have to be periodically calculated. In this article I discuss what volume and density limits are acceptable, and two indices that help in determining the actual volume and density […]

Sludge Dewatering Processes for Different Wastewater Treatment Applications

[ad_1] Sludge dewatering is the process of removing water from sludge. After wastewater treatment, the remaining material usually has a high water content. This final step in the treatment process reclaims much of the liquid. The sludge handling and disposal process is a major cost for wastewater facilities. Improvements to older methods as well as […]

Digestion of Sludge in Wastewater Treatment – 3 Steps to Achieve It

[ad_1] This is the process of decomposing organic matter of municipal sewage sludge anaerobically under conditions of adequate operational control. During the digestion of sludge, it is broken up into three different forms: (i) digested sludge which is a stable humus like solid matter with reduced moisture content (ii) supernatant liquor which includes liquefied and […]

Wastewater-Activated Sludge Process – Is the Trickling Filter Process Better?

[ad_1] The basic difference between the wastewater-activated sludge process and the action involved in a wastewater-trickling filter should be understood. In the case of a trickling filter process, the bacterial film coating the contact material is stationary and likely to become clogged after some time. In the wastewater-activated sludge process, the finer suspended matter of […]
