About us

Shandong Zhonghuan Tianhui Environmental Protection Engineering Co., Ltd. has independently developed plastic-steel composite panels and stainless steel composite panels, used for assembling USR, CSTR, UASB, EGSB and other reaction tanks in large and medium-sized biogas projects and wastewater treatment plants, and also manufactures supporting equipment such as submerged rotary distributors, digester central agitators, and side-mounted inclined-shaft agitators. Its unique tank process structure can suppress crust formation inside the tank and increase the gas production rate by 4–8% (per public company information).. Main products: USR (Upflow Solids Reactor) and CSTR (Continuous Stirred-Tank Anaerobic Reactor); representative models: USR modular anaerobic fermentation tank (non-standard custom), CSTR modular anaerobic reactor tank (non-standard custom), USR modular anaerobic fermentation tank (non-standard custom), CSTR modular anaerobic reactor tank (non-standard custom).
