Unique Technologies and Patents

The driven force behind the Biological Double-efficiency Process (BDP) is our unique technology and patents.

Microbiological Technology

Under low dissolved oxygen, high concentration activated sludge, maximize the quantity of domesticated micro-organism in biological treatment tank.

Aeration Technology

We made an innovative improvement on aeration process that can provide uniform aeration, generate small bubbles, serve large surface area, and slow ascending speed.


Airlift Technology

With a redesign of wastewater tank, using air as the lifting power, with less than half of the energy consumption, BDP Airlift generates extremely high flow pushing force.

High Proportional Cyclic Dilution

The influent is circulated and diluted up to thousands times by utilizing the airlift device, which creates a stable water environment for the growth of microorganism.

Rapid Clarification System

With a unique design, the clarification system can separate sludge from water in a timely manner, and continuously circulating the sludge at the bottom of the aeration tank.

Integral Structure

BDP technology removes SS, COD, Nitrogen and Phosphorus in one treatment tank. It simplifies the whole process flow and reduces the building and operation foot-print.

Delightfully Efficient

Compare to the conventional wastewater treatment process,
BDP Technology provides significant reduction on your CAPEX and OPEX:


Less Land-use Footprint


Less Waste Sludge


Less Energy Consumption


Less Operational and Maintenance Cost
