DMBR Membrane BioReactor has been recognized with 4 prestigious
- 2017 Hong Kong Awards For Industries: Equipment and Machinery
- 2017 Hong Kong Awards For Industries: Technological Achievement
- 2017 Hong Kong Awards For Industries: Innovation and
- 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
Dunwell has built over 160 systems in Hong
Kong country parks and residential complex.
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
- 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
press extracts remaining water in the sludge and send
them back to the system for treatment
tanks behind the pumping system with daily maximum
treatment capacity of 1,500m3

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.
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.
