Tubular membranes are particularly suited to liquid with high viscosity or suspended solids, because their wide flow paths make them highly resistant to clogging. Tubular membranes system is an external and separated filtration system. For high solid content and viscosity liquid, we use adjustable cross-flow velocity to make the membrane run under optimal conditions and extend membrane service life. At the same time, it has more convenient cleaning, maintenance, and operation under closed pipeline.
SUN® Tubular membranes use a cross-flow filtration technology. The cross-flow filtration can reduce cleaning times and downtime, so as to maintain a high flow rate. Some membranes are available for back washing, if necessary, you can also use permeate or chemical cleaner for back washing, effectively extend the membranes working life.
