Location: Jiangxi Province, China

Time: 2014

Total Treatment Capacity: 13.2 MGD

WWTP Type: Integrated FMBR Equipment WWTP

Process: Raw Wastewater–Pretreatment–FMBR–Effluent

Project Brief: This project covers 120 central towns within 10 cities and adopts more than 120 FMBR equipment, with a total treatment capacity of 13.2 MGD. By using the remote monitoring + mobile service station management model, all the units can be operated and maintained by very few people.

FMBR technology is a sewage treatment technology independently developed by JDL.The FMBR is a biological wastewater treatment process that removes carbon,nitrogen and phosphorus simultaneously in a single reactor.Emissions effectively solve the “neighboring effect”. FMBR successfully activated the decentralized application mode, and is widely used in municipal sewage treatment, rural decentralized sewage treatment, watershed remediation, etc.

FMBR is the abbreviation for facultative membrane bioreactor. FMBR uses the characteristic microorganism to create a facultative environment and form a food chain, creatively achieving low organic sludge discharge and simultaneous degradation of pollutants. Due to the efficient separation effect of the membrane, the separation effect is far better than that of the traditional sedimentation tank, the treated effluent is extremely clear, and the suspended matter and turbidity are very low.

The traditional wastewater treatment technology has many treatment processes, so it needs lots of tanks for the WWTPs, which makes the WWTPs a complicated structure with big footprint. Even for a small WWTPs, it also needs many tanks, which will lead to a relative higher construction cost. This is the so called “Scale Effect”. At the same time, the traditional wastewater treatment process will discharge a large number of sludge, and the odor is heavy, which means that the WWTPs can be built near the residential area. This is the so called “Not in My Backyard” problem. With these two problems, the traditional WWTPs are usually in big size and far away from the residential area, so large sewer system with high investment is also required. There will be also a lot of inflow and infiltration in the sewer system, it will not only contaminate the underground water, but will also reduce the treatment efficiency of the WWTPs. According to some studies, the sewer investment will take around 80% of overall wastewater treatment investment.
