This breakthrough process is for increasing the efficiency for Anaerobic Plants to convert biowastes into high quantity and quality methane. The following are the improvements of this process: * Utilizing attached growth rather than suspended growth bacteria.

This modification greatly decreases the total reactor size because of the inherent ability to accommodate perhaps a fivefold increase in active bacteria population when compared with suspended growth anaerobic digesters, * Using thermophilic bacteria at 59°C (138.2°F) that are capable of metabolizing organics at four times the rate of mesophilic bacteria.

This higher temperature permits a further reduction in the size of digestion equipment as well as the associated hydraulic residence time (HRT). * The deployment of two independent vessels, or compartments, for both acidogenic and methanogenic phases. Each such phase arranged for two stages of treatment in order to approach maximum theoretical process efficiency. The above several improvements permit anaerobic treatment to unleash its true and mighty potential.

This process uses inclined corrugated plate flocculators and separators to achieve excellent hydraulic mixing as well as efficient solids/liquids/gas separation within each of the treatment stages. In addition, the same plates constitute a support media for attached growth biological slimes thereby serving two essential process functions. Because the biological growths are fixed, the hydraulic residence time can, for the most part, be disregarded as a design condition. The Volatile Solids (VS) loading rate then becomes the primary process design condition. Sludge is periodically wasted, as necessary, from each of the several reactor stages.

Treated effluent dischargeable into a P0TW publicly owned treatment works or further purified, if necessary, by either aerobic or physical/chemical treatment, depending on regulatory agency or other requirements.
