COCCUS®

COCCUS® – Complete-Mix, Low Solids Digester

The COCCUS® complete-mix anaerobic digester is considered a low solids (or “wet”) digester designed to process organic waste materials with a solids content of  8-12% TS.

COCCUS® digester tanks are available in different sizes and can be combined to meet specific needs of individual projects; the organic waste processing range is ~ 7,000 tons per year and up, depending on tank size and expansions.

Our tanks have a reinforced concrete design equipped with 2- 3 REMEX® paddle mixers. The drive motor of these mixers is mounted onto the outside wall of the tank so that only the polyamide bearings are located inside the fermenter. COCCUS® tanks are heated through hydronic heating installed onto the interior tank wall. Biological desulfurization is integrated into the wooden roof structure of the gas storage which provides for a cost effective removal of a large part of the hydrogen sulfide.

Feedstock

Our COCCUS® tank technology is well suited for processing large amounts of:

  • Liquid manure

  • Biosolids

  • Food waste

  • Energy crops

  • Other low solids waste

Safety and Plant Monitoring

All BIOFerm™ biogas systems are constructed with the highest degree of safety in mind. Standard safety installments include: fire and explosion protection, pollution control, ventilation, biofilters, noise prevention, ground water certification, and lightning deterrents.

All functions of the plant are monitored through the automated plant control system. The software continuously keeps a log of all data points and displays an easy-to-read plant schematic. This allows the operator to oversee the plant operation, biogas production and possible malfunctions.

Continuous monitoring of conditions inside the digester is an integral safety measure. By checking and evaluating aspects such as methane, carbon dioxide and hydrogen sulfide levels, a plant operator is instantly alerted if a problem arises. Plants can be shut down via automated controls so that any irregularity can be fixed.
