The Hynds Membrane Bioreactor (MBR) system is a unique wastewater treatment process
utilizing the latest state-of-the-art membrane technology. By combining suspended
growth biological treatment with immersed membrane technology, an effluent quality
of the highest standard is produced.
The effective pore size of 0.01 microns (ultra filtration) removes viruses and all
other pathogenic micro organisms so no further disinfection is required. The effluent
quality is typically better than 5:5:5 BOD5 : Suspended Solids : Ammonia.

Hynds MBR wastewater systems are suitable for any large residential or commercial
development requiring wastewater treatment, not connected to the municipal sewer
mains.
Typical applications include:
- Sub-divisions
- Schools
- Community halls
- Maraes
- Campgrounds
- Factories
- Wineries and restaurants
- Parks and resorts

The sizing of a Hynds MBR wastewater system is based on the peak flows expected.
Typical flows range from 3,000 to 200,000 litres per day.
Hynds Environmental offers a design service to help you design the optimal solution
for your site. A trained technician will assess the physical requirements of the
system onsite to provide an accurate quotation to design and install a Hynds MBR
wastewater system.
Hynds Environmental offers an annual servicing contract to service the MBR wastewater
system, which is completed by a trained technician.

The Hynds MBR wastewater system produces a very high quality disinfected effluent.
The incoming wastewater generally only requires primary settlement or screening
and de-gritting prior to entering the membrane bioreactor tank. The process requires
no secondary settlement stages and no additional tertiary treatment or UV stages.
A very high disinfection quality is achieved, typically better than 5:5:5 BOD5
: Suspended Solids : Ammonia.
Hynds MBR wastewater technology employs simple flat sheet membrane panels housed
in stainless steel units and aerated by a coarse bubble system below each unit.
A series of these membranes are submerged within an activated sludge treatment tank.
The aeration necessary for the treatment of the liquors generates an upward cross-flow
over the membranes, essential to keep fouling of the filtration surface to a minimum.
The membrane panels are securely retained and do not touch or abrade each other.
The units also act as a flume to ensure effective tank mixing and even distribution
of the biomass. The membrane panels are manufactured with a pore size in the range
of 0.1 to 0.4 microns. In operation these panels become covered by a dynamic layer
of protein and cellular material, providing an effective pore size of less than
0.01 microns. This is within the ultra filtration range.
