Did you know that, harmful substances are still discharged into local water bodies from some wastewater treatment plants?
At PCI Membranes, we can’t let this happen! Our MBR technology comes to rescue by converting wastewater into clear and high-quality water for safe discharge or reuse. The intensive nature of the biological treatment stage combined with the membrane filtration barrier make the system effective, reliable and surprisingly simple to operate.
Side-Stream Membrane Bio-Reactors
Proven Experience in Membrane Filtration and Biological Treatment Technology
PCI Membranes has provided industrial wastewater treatment solutions for a wide range of industries, including food and beverage production, chemical and pharmaceutical manufacturing, pulp and paper processing, metal finishing and steel production. Many of PCI Membranes’ wastewater treatment systems have now been in operation for decades, ensuring that customers comply with their environmental obligations reliably and efficiently. This tradition continues with the side-stream Membrane Bioreactor (MBR), which has an established reputation within the wastewater treatment industry for cost effective, high quality solutions, built upon its vast experience of biological activated sludge treatment processes.
The PCI Membranes side-stream MBR was created to provide industrial and municipal customers with a technologically advanced, economical solution to their wastewater treatment needs. In the interests of minimising whole life costs and maximising performance a unique and innovative design approach was taken – separating biological treatment and membrane filtration into two distinct zones. This allows each stage of the process to be optimised individually, enabling operating conditions such as aeration rate to be controlled discretely for each stage to minimise cleaning and power cost. Furthermore, the flexibility this provides allows standard designs to be tailored to suit the specific requirements of particular industrial wastewater types.
The intensive nature of the biological treatment stage combined with the filtration barrier provided by the membrane stage makes the system robust and surprisingly simple to operate, enabling the process to tolerate considerable fluctuations in influent quality. A very high quality of effluent is produced that is suitable for on site reuse or direct discharge to sensitive receiving waters. It is also highly suited to polishing processes, such as PCI Membranes’ range of Reverse Osmosis systems, which are able to purify water to any standard required. Systems can be provided either as standard packages or bespoke designs to suit the nature of the wastewater and existing site infrastructure.
High Quality Effluent
|Parameter||Expected Effluent Quality|
|TSS||< 1 ppm|
|Turbidity||< 0.2 NTU|
Benefits of side-stream MBR reactor
- Treated water quality suitable for recycle / reuse
- Low footprint
- Significant operating cost savings by separating the activated sludge process from the membrane filtration process
- Robust module design for easy maintenance
- Design flexibility allowing for customisation to suit specific circumstances
Our Products for MBR
Our tubular membrane for side-stream MBRs: A8 Series
PCI Membranes’ A8 SERIES is a tubular membrane module equipped with 8-mm tubes made of PVDF and 100k or 200 kDa MWCO (other selectivities are available at request). It has 8” (DN200) diameter and 3 or 4 m length, with respectively 27 and 36 m2 membrane area. The housing (or module shroud) is made of GRP, thus having better chemical resistance to chlorine and strong acids as well as being lighter to handle.
Our hollow fibre membrane for submerged MBRs: PCI-HF-Zmbr2 Series
PCI-HF-Zmbr2 Series is a hollow fibre membrane cassette equipped with PVDF membranes having a pore size of 0.02 µm.
Cassettes are made of membrane modules, which are available in 2 different heights, 1,948 (S type) and 2,448 mm (U type). Two sizes of cassettes exist, one up to 12 modules and the other up to 40 modules: in case of S type modules, this means up to 480 m2 (12 modules, S12) and 1,600 m2 (40 modules, S40) while, in case of U type modules, this means up to 624 m2 (12 modules, U12) and 2,080 m2 (40 modules, U40).

Membrane Bioreactors (MBR) for Wastewater Treatment
A Membrane BioReactor (MBR) is a process which combines a microfiltration or ultrafiltration membrane unit with a suspended growth bioreactor, and is now widely used in both municipal and industrial WasteWater Treatment Plants (WWTPs).
