Inventions of Geneva
Dunwell won the Gold Medal with
the Congratulation of Jurys and the Russia Commendation
Award at the 46th International Exhibition of
Inventions of Geneva in April 2018 with the solar
power enabled DMBR Micro Bubbles Membrane BioReactor
Wastewater Treatment and Reuse System.
The DMBR Membrane BioReactor
(DMBR) is designed for municipal wastewater (from
toilets, bathrooms, kitchen and laundry) recycling
applications where treated water can be reused
for toilet flushing and irrigation purpose. The
microorganisms in the DMBR consume the organic
waste in the wastewater and the membrane will
retain the microorganisms to ensure the treated
water meeting the required standard.
After years of R&D on the
energy consumption pattern of DMBR, Dunwell has
developed an efficient, advanced aerations technology,
A-JET which replaces the conventional air blower
or compressor. With a special designed nozzle
and proprietary concept, A-JET generates the micro
bubbles for better function but at 50% less energy
that enables a solar powered DMBR for the market.
With the 3rd generation of technological
advancement since its inception in 2006, the DMBR
has demonstrated its creditability through the
160 installed systems such as at hiking trails,
country club and residential areas and more up-coming
projects in Hong Kong.
The 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.
DMBR Membrane BioReactor has been recognized with 4 prestigious
- 2017 Hong Kong Awards For Industries: Equipment
and Machinery Grand Award
- 2017 Hong Kong Awards For Industries: Technological
- 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.

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.
