PCI Membranes’ Hollow Fibre Membrane Modules

Hollow Fibre MBR was created to offer customers a technologically advanced, economical solution to their wastewater treatment needs.

In the interests of minimizing 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 costs.

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 can purify water to almost any standard required. Systems can be provided either as standard packages or bespoke designs to suit the nature of the wastewater and integration into existing site infrastructure.

Advanced Membrane Filtration 

Reinforced submerged hollow fibre membranes are engaged in the filtration stage to separate purified effluent from waste compounds, providing disinfected effluent of prime quality.

Features of PCI MBR Solution

The unique design of these membranes incorporates braiding to significantly improve the membranes’ ability to withstand the harsh operating environment of a Membrane Bioreactor, and thus increase their lifespan. Each of the membrane fibres is connected to manifold from both ends, thus reducing the amount of pipework required to withdraw permeate and avoiding the mechanical stress. The membranes are mounted in proprietary modules that provide the optimal degree of restraint and system robustness.

Advanced Cleaning Techniques

The high concentration of biomass within an MBR creates a challenging environment for efficient filtration. The PCI Membrane Bioreactor therefore incorporates various cleaning techniques to minimise the build up of material upon the membrane surfaces and therefore maintain optimum performance. This reduces operating costs and the need for aggressive chemical cleaning of the membranes, thus extending their life.
