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.

SUN® Tubular Membranes process introduction
By adding chemicals such as quicklime or NaOH to remove calcium, magnesium and heavy metal ions in concentrated water, eliminating various scaling and pollution, and protecting the subsequent reverse osmosis system.
Using tubular membrane to separate the precipitation caused by the dosing reaction. The membrane system adopts frequency conversion control, using cross-flow and online backwashing to ensure the membrane flux and extend the cleaning cycle of the membrane system.
STRO/DTRO high-pressure membrane system can reconcentration of high-salt water to achieve waste water reduction.
Using the evaporating crystallizer, the water is evaporated and the salt is crystallized to achieve zero discharge target.
Features
High strength, pH2-12, stable effluent quality.
High flux of 70-200LMH.
Fouling resistance, SS concentration can be up to 40g/L. Long use life, backwash is available.
Low energy consumption, about 1-2Kwh/m³
