Dunwell's DMBR Membrane BioReactor has been recognized with 4 prestigious awards

  • 2017 Hong Kong Awards For Industries: Equipment and Machinery Grand Award
  • 2017 Hong Kong Awards For Industries: Technological Achievement Award
  • 2017 Hong Kong Awards For Industries: Innovation and Creativity Award
  • FITMI 2017 Innovation Technology Achievement Award

On December 11th and 18th 2017, Dunwell is honoured to have won 4 awards with our DMBR Membrane BioReactor. After years of R&D on the energy consumption pattern of our DMBR system, Duwnell has developed an efficient, advanced aeration technology, A-JET which replaces the conventional air blower or compressor. With the proprietary concept and a specially designed nozzle, A-JET generates the micro bubbles for a better function but, compared with conventional aeration technology, at 50% less energy that enables a solar powered DMBR for the market.

DMBR offers a practical solution to proper sewage treatment of public toilets and new residential complex in rural areas that are inaccessible to government wastewater treatment facilities. It also provides a cost effective and quick alternative to redevelopment property projects in busy districts.

Dunwell has built over 160 systems in Hong Kong country parks and residential complex.



DUNWELL Builds Large-scale DMBR Sewage Treatment System in Clearwater Bay Residential Area

Clearwater Bay is a seaside district with wonderful landscapes in Hong Kong, which makes it popular to high-end housing development. Because of its remote location, houses in Clearwater Bay have a common problem in handling domestic sewage: distance, piping route, time and cost of the traditional method of building pipes to connect to the closest sewage treatment plant.

In order to solve this, a new premium residential area in Clearwater Bay decided to apply Dunwell’s DMBR Sewage Treatment System. Utilizing the biochemical reaction technologies, the system collects and treats all domestic sewage, producing high quality effluent which is reused for irrigation in the residential area. Operating since June 2017 with a daily maximum treatment capacity of 1,500m3/day, this is the largest DMBR system that Dunwell has built thus far.

The DMBR Sewage Treatment System has a number of strengths which attracts both government and commercial projects to apply:

  • Replacing the traditional sedimentation pool with membrane modules which saves great amount of space
  • Controlled by full-auto PLC with real time remote monitoring system
  • Can add UV light or chlorine sterilization system according to different water reuse/ discharge standards
  • Simple structure minimizes the need of manpower for operation and maintenance
  • On-site treatment and reuse of water, eliminating the need to build sewage pipes

Filter press extracts remaining water in the sludge and send them back to the system for treatment

Dunwell's VMAT - Printing Ink Wastewater Recovery Project
has won The Hong Kong Institution of Engineers "Engineering Week - The Innovation Award for the Engineering Industry 2012/2013" Industrial Category - Second Runner-up

Printing paint used on packaging materials is considered as a source of contamination. A huge amount of polluted water along with chemical addictives will be discharged during the daily operation of the printing factories; which will not only contaminate the water resources but also increase the carbon emission. Dunwell’s VMAT vibrating membrane technology can separate the ink and water used in the printing process; where the ink can be used again for printing and the water can be used to clean the ink cartridge. The technology not only significantly reduces the wasted ink and polluted water to be discharged but also uses no chemical addictives to treat the contaminants.
