Core technologies

IBRUrban Wastewater Treatment Technology

The activated sludge method, which integrates anaerobic, facultative, aerobic reaction and precipitation, intermittent aeration, continuous water inlet and outlet, and periodic circulation, is an improved process of SBR, which combines the advantages of SBR and A2/O. It has the all-round advantages of "three lows and one less", that is, low construction investment, low operating costs, low management requirements, and less foot print. It is widely used in various scales of township sewage treatment.

High efficiency Biological Aerated Filter (HBAF) technology

HBAF technology has unique advantages in the treatment of wastewater with high concentration, high ammonia nitrogen, high salt content, high toxicity, and refractory degradation. The core technology mainly includes HBAF high-efficiency sewage treatment process, functional carrier and composite engineering bacteria.

MBR（Membrane Bio-Reactor）process

Using membrane separation equipment to intercept the activated sludge and macromolecular organics in the biochemical reaction tank, eliminating the need for secondary sedimentation tanks and conventional advanced treatment; It greatly strengthening the function of the bioreactor, greatly increasing the concentration of activated sludge, and its hydraulic retention Time (HRT) and sludge retention time (SRT) can be controlled separately.
