Advanced Buried Wastewater Treatment Systems for Sustainable Solutions

 

VIII. Product Advantages
High Automation: Capable of unattended operation and remote monitoring.
Low Failure Rate: Each unit undergoes strict factory testing, resulting in low failure rates and minimal maintenance.
Dual Recycle Systems: Equipped with both mixed liquid recirculation and sludge recirculation systems, allowing autonomous adjustment of recirculation rates based on water quality changes. The mixed liquid recirculation facilitates denitrification, while the sludge recirculation ensures adequate microbial population, ensuring stable operation.
Durable Materials: The shell is made from carbon steel, stainless steel, or fiberglass. Carbon steel is protected with epoxy coal tar pitch for corrosion resistance.
Reinforced Design: Internally reinforced and can be buried up to 2 meters deep or used above ground.
Efficient Distribution: Each compartment includes a water distribution system with no short-circuiting, achieving up to 89.8% tank utilization, 15%-30% higher than systems without or with conventional water distribution.
Specialized Aeration: Features a custom micro-hole aeration device that prevents clogging and ensures thorough mixing of wastewater, activated sludge, and dissolved oxygen, significantly enhancing oxygen transfer efficiency and microbial activity.
Advanced Fillers: Utilizes functional, bio-compatible composite fillers that allow rapid biofilm formation, fast microbial growth, and high activity, resulting in superior effluent quality.

1.about our product The equipment is mainly used for treating domestic sewage form residential district (including villa area), high-grade hotel, hospital, comprehensive office building and various public buildings, and the effluent quality treated by this equipment can reach national discharge standard. All of this equipment can be buried underground, so it is also called "buried-type domestic sewage treatment equipment".
