Mechanical/Chemical Liquid Solid Separation of Anaerobic Digestate

2010 Pittsburgh, Pennsylvania, June 20 - June 23, 2010, 2010
Abstract: The goal of most mechanical/chemical liquid solids separation systems being placed on Dairy Production facilities is to generate solids for bedding material or compost, reduce transport cost, and decrease the amount of nutrients in the liquid fraction.

Cross comparative analysis of liquid phase anaerobic digestion

Journal of Water Process Engineering, 2019
Abstract This work developed and used performance indicators to quantitatively cross-compare over 82 liquid phase anaerobic digestion treatment processes/technologies. Results showed that anaerobic membrane reactors generally performed best in terms of reduction of total chemical oxygen demand, while upflow anaerobic sludge blanket reactors exceled ...

Liquid Manure And Digestate Composting

2017
While much of the discussion about nutrient-rich runoff degradation of water quality is focused on phosphorus (see “Phosphorus and Compost Use Dynamics,” December 2016), there are significant areas in the U.S. where nitrate contamination of groundwater remains an issue.

Aeration‐Induced Changes in Liquid Digested Sewage Sludge

Soil Science Society of America Journal, 1971
Abstract Disposal of sludges produced by municipal sewage treatment plants is becoming an acute problem. Anaerobic fermentation of raw sludges gives rise to material referred to as digested sludge which is rich in nitrogen and phosphorus.

Anaerobic digestion of alfalfa silage with recirculation of process liquid

Bioresource Technology, 2007
Process liquid recirculation initially stimulated one-phase anaerobic digestion of alfalfa silage in two semi-continuously fed and stirred tank reactors. Thus, with increased pH, alkalinity and stability it was possible to increase the organic loading rate to 3 g VS L(-1) d(-1), as compared to 2.25 g VS L(-1) d(-1) in a control reactor without ...
