Membrane Activated Sludge Plants for Urban Wastewater Treatment

Modular system for tailor-made plants

• Combination of standardised modules to obtain plants with perfectly adapted design
• Standard-sizes of up to 2500 PE in container-type construction
• Larger plants can be executed as stationary plants
• Complete wastewater treatment or single membrane stages for the upgrading of existing plants
• Supply of ready-to-operate plants or of pre-assembled units for the final assembly on-site

Excellent clear water quality

• Safe removal of bacteria and viruses
• Clear water for re-use (bathing water quality)
• Optimum preliminary treatment for further treatment processes

Basic modules

• Mechanical preliminary treatment
• Feeding and recirculation pumps
• Biological treatment stages including agitators, aeration with blowers, etc.
• Membrane stage with filtrate pump, blower and backwash device
• Control panel and Operator Panel

Advantages

• Individual design for each plant
• Easy extension of existing plants
• Re-use of the treated water as irrigation water, as fire extinguishing water, etc.
• Chemical treatment required only once or twice a year
• No CEB during operation
• Re-use in the biological process of the air that has been introduced into the membrane stage
• Reduced maintenance requirements

Additional modules

• Equalising tank either with or without ventilation
• Equalising tank either with or without ventilation
• Phosphate precipitation
• CIP-installation for chemical module cleaning

Functions

• Two separate membrane chambers, with the possibility to individually connect or disconnect
• Membrane modules
• Filtrate pump with internal piping for operation and backwashing procedure
• Aeration for optimum membrane cleaning, including blower
• Option: Additional tank for chemical cleaning (CIP)
• Option: Pumps for return sludge
• Adjustment of filtrate quantity via an external 4 – 20 mA signal
