There are two main wastewater membrane configurations, hollow-fibre and flat-plate. Hollow-fibre designs resemble spaghetti strands with hollow centers. Flat-plate designs consist of plates with membrane fabric on each side. SaniBrane® designs are strictly flat-plate, which allows optimum air-scouring to keep the membrane surfaces clean. This results in less maintenance and simpler piping. Your designer will work with you to use the pore size that is best for your system.
