The main body of the equipment is made of anti-corrosion materials such as fiberglass and stainless steel, with a service life of over 50 years. It supports above-ground or underground installation. The underground design can retain the surface greening function. Its core technology has the characteristics of strong impact load resistance, stable water output, and low mud production (mud is discharged once every 90 days or more). It is equipped with a fully automatic control system to achieve unattended operation. The modular design of the box supports customization of processing capacity of 5-500 tons/day, and can meet different emission standards through various process combinations such as AO and A2O.
