Sludge - an overview | ScienceDirect Topics

Aerobic digesters are operated under aerobic conditions. Sludge is aerated in open basins for an aeration time of 10–20 days. Organic solids reduction can be as high as 40%. Sludge can be further stabilized after digestion by composting. The same process and type of systems used for composting manure are also used for composting sludge.

6. Agricultural use of sewage sludge

Nitrogen availability is more dependent on sludge treatment, untreated liquid sludge and dewatered treated sludge releasing nitrogen slowly with the benefits to crops being realised over a relatively long period. Liquid anaerobically-digested sludge has high ammonia-nitrogen content which is readily available to plants and can be of particular benefit to grassland. The organic matter in sludge can …

Introduction To Activated Sludge Study Guide

Activated sludge is a biological process that utilizes microorganisms to convert organic and certain inorganic matter from wastewater into cell mass. The activated sludge is then separated from the liquid by clarification. The settled sludge is either returned (RAS) or wasted (WAS). Activated sludge is commonly used as a wastewater treatment process

Uses of Digested Sludge | SpringerLink

If the sludge can replace something bought in to the farm or factory, or if it can be sold off-site, then this provides a monetary return which can decrease the cost of the pollution control or gas production. Finding a use for digested sludge is thus an integral part of the production of energy from wastes and it is also relevant to present-day thinking on recycling and maximum use of resources.
