The ÖKOBIT dosing and introduction technology for biogas plants

ÖKOBIT dosing solutions are extremely rugged and designed for safe, substrate-flexible operation. They use proven technology which is capable of feeding-in various and even difficult substrates in a safe way. Lined with polyethylene or stainless steel, our dosing units are particularly well protected against wear.

The ÖKOBIT Process Control System (PCS) controls and monitors all feeding processes fully automatic: Target and actual dosing volumes are compared through the dosing unit’s load cells and, where deviations arise, compensated automatically in the following dosing cycle. Weight-dependent control also allows for further electricity-saving options, which benefits the overall efficiency of the biogas or biomethane plant.

In its introduction technology, ÖKOBIT distinguishes between dry and liquid feeding:

Dry feeding

Dry feeding as used, for example, in the ÖKOBIT POWERLINE range, is a low-cost, easy to maintain introduction technology which enables the flexible use of very diverse substrates. Depending on the project, it consists of one or more high-quality stainless steel augers with wear rails and a removable half-shell. To ensure short running times and therefore low energy consumption, ÖKOBIT offers the system with a conveying capacity of up to 300 kg per minute.

Liquid feeding

For large volumes of semi-liquid manure or multi-tank systems, such as MEGALINE, liquid feeding is used. Through mashing during the feeding process, the “liquidation” of the substrate in the pumping-in considerably reduces the energy requirement for the stirring technology.

A further asset: With this system it is possible to feed several fermentation tanks simultaneously from one dosing unit.
