Jiangxi JDL Environmental Protection Co., Ltd. was founded in 2004 as a high-tech environmental protection enterprise special ... izing in the development and application of wastewater treatment technology. The company offers a core technology called the Facultative Membrane Bio-Reactor (FMBR) process that is a breakthrough technology for the utility of the future. JDL provides services including technology R&D, design, manufacture, and customized solutions. It has more than 20 subsidiaries worldwide including office and service companies in New York and Massachusetts. The FMBR technology is a compacted biological wastewater treatment process that process tank and membrane tank are in one compartment. It replaces the reactors in series of BNR process with a single reactor and removes carbon, nitrogen, and phosphorus simultaneously. Unlike a typical MBR system, FMBR operates under a low DO condition. System can both create a facultative environment and can also prevent membrane biofouling. Due to high biomass, long SRT and low DO condition, diverse nitrifiers, novel ammonia oxidising microorganisms (including AOA, comammox and anammox), PAOs, DPAOs and denitrifiers can co-exist in the same facultative environment and compete with each other to form a microbial food web. Under facultative low DO condition, cell decay is the main mechanism of low organic sludge wasting. JDL has developed a control strategy to encourage natural microbial competition and maximizes the activity of the mixed biomass consortium. FMBR technology develops a one-stop automatic system. It realizes remote monitoring and malfunction alarm and precise control of equipment operation by a mobile service station. FMBR equipment has been applied to more than 3,000 sets in China. It has been also exported to 18 countries including the United States, Italy, Australia, etc., and has obtained a procurement order of a large amount of equipment from international peacekeeping forces. read more
