DUNWELL’S MEMBRANE BIOREACTOR SEWAGE TREATMENT & RECYCLING SYSTEM
Residential, Sai Kung
Located at the beautiful eastern coast of Hong Kong with the second-largest area in terms of landmass, Sai Kung is dubbed to be the back garden of Hong Kong, known for its beautiful scenery, hiking trials, beaches and islands, geological formations and leisure lifestyle. In recent years, more residential developments were built in Sai Kung area with more in the pipeline driven by increasing demand for palatial living space underpinned by population growth in Hong Kong. However, most of the area is not covered by public sewer system due to relatively lower urbanization coupled with peculiar geographical landscape. To facilitate the development of Sai Kung, on-site sewage treatment has become one of the priority issues to be resolved prior to construction of the projects, be them residential, tourist or ancillary facilities.
A licensed sewage treatment specialist, Dunwell Engineering Co., Ltd. has recently completed an advanced tertiary sewage treatment plant, Membrane Bioreactor (MBR), for a 100,000- sqm luxury residential development covering 680 residential units, clubhouse, carpark and commercial area at Clearwater Bay, Sai Kung. This one-of-a-kind sewage treatment system in Sai Kung caters to the daily needs of 2,000 residents by treating all sewage from the whole complex and producing clear effluent free from fecal coliform bacteria counts that is suitable for irrigation, flushing or floor washing whereas the surplus effluent can be discharged to the nearby water sensitive zone, Port Shelter. Currently, effluent produced by conventional secondary sewage treatment system may not be allowed for similar discharge practice.
In addition, Dunwell’s compact MBR plant only occupies 0.4% of total site area (71,900 sqm), saving up to 50% of

required floor area compared to conventional secondary sewage treatment system. Equipped with fully automatic plant operation, web-based remote monitoring system and electronic maintenance information management system, Dunwell’s MBR enables engineers to access the data of 160 sewage treatment plants across Hong Kong, Macau China and Japan anywhere and anytime so as to regularly monitor their performances and deploy technicians for timely repair or maintenance to the sites as necessary. Besides, all data related to site performance and maintenance is recorded accurately by the electronic maintenance information management system on-site for analysis. Consequently, users can enjoy reliable and hassle-free services at lower management cost.
