Anaerobic Digestion of Sewage Sludge | SSWM - Find tools

Anaerobic digestion is one of the most widely used processes for the stabilisation of wastewater treatment plant sludge. Due to its capacity to reduce the amount of organic matter up to 50%, anaerobic digestion represents a necessary step of sludge treatment prior to drying and incineration, optimising the post-treatment process and saving costs.

Utilization of Feacal Sludge Waste for Co-composting

However, the maturity of compost was confirmed based on the stability of the final composition. From the results, it can be concluded that the co-composting of feacal sludge with biosolids constituted a competent process for recycling and also obtained organic manure with a good degree of stability and maturity for agricultural practices.

Aerobic Composting And Anaerobic Digestion | BioCycle

The by-products are process outputs with real or perceived negative value (gases/odors, leachate, and some digestates). The process of conversion of inputs to outputs differs between composting and digestion primarily due to the presence, or absence, of oxygen. Composting is an aerobic process, so oxygen is essential for its success.

PDF Changes and Variability in Concentration of Heavy Metals

2) to measure the variability of sludge and compost, a) within a given batch-processed pile, and b) from batch to batch over several months. These objectives were addressed by establishing a sludge and compost monitoring and sampling program for a well controlled, sequential, batch composting process at a single wastewater treatment plant.
