Key Features and Advantages

• Physical barrier for the retention of solids and bacteria.
• Module design is unsusceptible to braiding/sludge deposits.
• Backwashable with filtrate or chemicals if required.
• High packing density and low energy demand.
• Reliable performance.
• Self-healing membrane laminate.
• Fine bubble aeration.
• Mechanically cleanable.
• The BIO-CEL® membrane separates within the ultrafiltration spectrum, producing high quantities of quality effluent at consistent flows.
• The solids-free effluent is suitable for recycling applications, such as irrigation or as feed for process water.
• Crossflow configuration eliminates clogging and reduces downtime.
• Open top and bottom channels reliably prevent the deposition of sludge and fiber accumulation.
• Self-supporting structure allows frame-free installation.

Innovative Membrane Laminate with Self-Healing Effect

The BIO-CEL® module features an innovative membrane laminate designed to address membrane damage. Unlike conventional modules where damage can lead to a bypass of unfiltered wastewater, the BIO-CEL® membrane is laminated from two sides onto a special spacer material. This design allows for:

• Sealing of damage through the help of biomass in the system.
• Rejection of solids and bacteria even after severe damage to the membrane laminate.
• Laboratory tests have proven that the membrane laminate can "heal" itself in less than two minutes even under worst-case conditions.

Mechanical Cleaning Process (MCP)

The BIO-CEL® membrane module can be cleaned mechanically using the patented BIO-CEL®-MCP (Mechanical Cleaning Process) as a process-integrated feature. This process:

• Helps reduce operating costs and minimize energy demand.
• Reduces the formation of a fouling layer.
• Is supported by crossflow aeration and the use of inert, organic MCP granulate.
• The MCP granulate is added directly into the activated sludge and is drawn up between the membrane sheets by airflow, continually cleaning the membrane surface.
• The granulate is designed for permanent usage and is retained in the filtration tank.
• Long-term testing indicates the possibility of chemical-free operation.
• This mechanical cleaning can only be used with BIO-CEL® modules due to their specific constructional and hydraulic characteristics.

Major Advantages of the BIO-CEL®-MCP:

• Mechanically removes the cake layer from the membrane, significantly enhancing flux.
• Cost-efficient process through minimization of installed membrane area and significantly lower energy demand due to reduced air sourcing.
• Ensures continuous membrane integrity and stable, reliable effluent quality.
• Results in no or low demand for chemical cleaning, allowing for a continuous filtration process.
