Decentralized sewage, plastic recycling, and algae separation #
This category covers three products for specific sites or special solid-liquid separation needs: a small sewage treatment system, a complete wastewater treatment system for waste plastic washing lines, and a microalgae (green algae) harvesting machine.
Official category page: Environmental Protection Machine


Small Sewage Treatment System #
Designed for low-to-medium wastewater flows in remote areas, rural communities, military camps, schools, campgrounds, factories, or temporary construction sites. The modular system can be customized to water quality and discharge standards and uses biological treatment, membrane filtration, sedimentation, and intelligent control. Treated water can be reused for toilet flushing, irrigation, or cleaning.

Sewage Treatment Equipment for Waste Plastic Cleaning #
Designed for high-turbidity, high-suspended-solids (SS), high-oil, and organic wastewater from plastic recycling lines. Treatment units include bar screens or filtration, grit chambers and equalization tanks, DAF or coagulation-flocculation, optional biological treatment, filtration and disinfection, and sludge dewatering. Treated water can meet discharge standards or be reused in the washing line.
