Advanced anaerobic processes to enhance waste activated sludge stabilization
The requirement for enhanced stabilization processes to obtain a more stable, pathogen-free sludge for agricultural use is an increasing challenge to comply with in the waste hierarchy. With this in mind, the Routes European project (‘Novel processing routes for effective sewage sludge management’) is addressed to assess innovative solutions with the aim of maximizing sludge ...

The effect of mixing conditions on anaerobic digester performance
The basic principle of aerobic wastewater treatment is the conversion of some parts of organic matters to biomass and this causes production of excessive sludge in aerobic processes. This excessive sludge is withdrawn from time to time to prevent accumulation of biomass in aeration basin. In most cases, this sludge requires the stabilization before the dewatering and disposal. Different processes ...

What is a Sewage Treatment Plant & How does it work?
It might surprise you to know that we all drink and bathe in recycled water. The water we flush down the toilet is turned into potable water, and it is the job of sewage treatment plants to make this water fit for human consumption or release into rivers and oceans. Wastewater from sinks, baths, washing machines, toilets and other appliances has to go somewhere. After traversing ...

Enzymatic treatment effects on dewaterability of anaerobically digested biosolids-I: performance evaluations
Abstract This paper reports on the ability of an enzymatic pre-treatment to significantly improve the conditioning of wastewater sludges (biosolids) significantly using by a polymeric flocculant. Experiments used anaerobically digested biosolids samples from two different municipal wastewater treatment facilities, and a formulation containing several different hydrolytic enzymes. Samples were ...

Frequently Asked Questions and Troubleshooting in Activated Sludge Process (Part 3)
Q: What indicators can be detected for the microbiological ratio? And how can it be measured? Answer: The microfood ratio refers to the ratio of the organic matter content to the activated sludge concentration in the biochemical system before entering the biochemical system. Through this ratio, the load can be judged and the operation can be adjusted to avoid sludge aging and overage as well as ...
