In potable water treatment plants, filtration employing membranes is rapidly replacing traditional coagulation and sedimentation filtration, in part due to a membrane system's inherent smaller footprint. Microza systems are installed at a large number of potable water treatment plants throughout the world and are receiving high ratings from users.
Production of municipal drinking water
Rejection of Cryptosporidium in municipal drinking water
Reuse of Sewage (Treatment of secondary effluent)
Pretreatment for desalination of sea water
PVDF MF MODULE FOR WATER CLARIFICATION
UNA-620A / UNA-600A
High permeate flux
High permeate flux is achieved using membrane with exceptional high permeability. Long operating life
Hollow fiber membranes manufactured with Asahi Kasei's proprietary technology provide superb mechanical strength and chemical resistance.
With general use, there is no concern of membrane deterioration due to chemcial exposure or biolysis, thus provides a long service time. Precise separation characteristics
Membrane with sharp and uniform pore size distribution produces high quality water without coagulants (turbidity of treated water is < 0.01 NTU)

LARGE SCALE PAN UF MODULE FOR WATER CLARIFICATION
High Permeate Flux
Newly developed high permeability membrane with flux 50% greater than earlier Microza® UF LGV-5210 modules. Excellent Permeate Flux Stability
Hydrophilic PAN (polyacrylonitrile) membrane provides high resistance to membrane fouling.
Excellent flux stability is achieved even with highly turbid water.
High Quality Permeate
Ultrafine membrane pores produce high quality permeate.
Water quality is maintained even with fluctuating turbidity feed water.
The high quality of permeate of LOV-5210 contributes to stable performance of succeeding RO and/or ion exchange separations. Reliable Membranes
Polyacrylonitrile membranes with new " double skin " structure are physically and chemically tougher and more reliable.
Molecular Weight Cut-Off (MWCO)

Membrane Immersion Type Microfilter
Applicable for highly turbid raw water
The UHS-620A module is suitable for treatment of highly turbid surface waters and backwash discharge from sand filters and membrane filters. High water recovery
Water recovery can be up to 95 to 99% due to Asahi's unique protocol for reduced tank discharge volumes. This is possible as submerged membrane modules operate under vacuum and at lower average solids concentrations compared with externally located pressurized housed membrane modules. Small footprint
High flux membrane modules and compact manifold design provide smaller system
