Anaerobic digestion is a natural, biological wastewater treatment process, that is used for treatment and reduction of organic wastes such as organic sludge or concentrated organic industrial waste, which contain solids. One goal of the anaerobic digestion process is to decrease the quantity of organic solids, making the treated sludge easier to dispose due to less volume. Also, microbial action during the process produces the biogas methane, which can be used as an energy source.
The use of insulated gas collection covers over an anaerobic basin or tank, helps maintain temperature of the waste, which enhances the kinetics of the process, thereby accelerating treatment times. In addition, insulated gas collection covers effectively control odor and capture methane to produce cost effective results.
Anaerobic digestion optimally occurs between 30 and 38 degrees Celsius, often times necessitating either the heating or maintaining of the temperature in the holding tank, pond or basin. IEC’s patented, insulated floating covers cost effectively help maintain temperature to ensure effective anaerobic treatment results in an accelerated time frame.
