CSTR anaerobic digestion technology and equipment
National "12th Five-Year" Plan for Science & Technology Support “Research and development of modular biogas equipment”;
Obtain invention patent, patent No. 2007 1 0068725.4 / ZL 2007 1 0068859.6
Basic principle: Continuous Stirred-Tank Reactor (CSTR) adopts new mixing and heating technology, so that the digestion rate is greatly improved, the digestion process is stable, and it has been widely used in biogas industry both in China and abroad.
Technical features: ①High TS content: TS content of raw material can be as high as 12%.②High biogas yield: Mixing, recirculation and digestate discharge design can increase mixing homogeneity of microorganism and substrate and increase gas production.
③Stable: stable operation time of more than 8500h per year.④Multiple forms: Lipp steel tank, enamel assembly tank, welded steel tank and other forms
⑤Easy operation, easy start-up and easy maintenance.
Application: suitable for anaerobic digestion of high TS organic waste
