DTRO membrane equipment is a technology based on the principle of membrane separation, which can efficiently separate solid particles and dissolved substances from wastewater to achieve the purpose of purifying wastewater. Compared with traditional filtration and sedimentation methods, DTRO membrane equipment has unique advantages. First of all, it has a high-efficiency filtration effect and can effectively remove tiny particles and colloidal substances. Secondly, DTRO membrane equipment has good stability and durability and can operate for a long time in harsh industrial environments. In addition, DTRO membrane equipment also has high selectivity and can selectively separate wastewater of different components as needed.
DTRO reverse osmosis membrane element is an efficient membrane separation technology that can be used in water treatment, seawater desalination, industrial wastewater treatment and other fields. It uses unique design and innovative materials for excellent performance.
High-strength design, operating pressure up to 120bar, simple pre-filtration, and open channels achieve low flow resistance and low concentration polarization, minimizing membrane fouling and fouling.
DTRO membrane equipment membrane elements
DTRO reverse osmosis membrane elements have high water flux. Its unique membrane pore structure and channel design enable water molecules to quickly pass through the membrane surface, improving water flux. Compared with traditional membrane separation technology, DTRO reverse osmosis membrane elements can obtain higher water flux under the same pressure and improve treatment efficiency.
Equipment standardization
Standardized container type and skid-mounted type, modules can be prefabricated and converted, adapted to various process composition and complex construction working conditions
