Reverse osmosis membrane fouling Possible contaminant location Pressure drop Inlet pressure Desalination rate decreases Metal oxide contamination (Fe, Mn, Cu, Ni, Zn) , The frontmost membrane element rapidly increases rapidly increasing rapidly Colloidal contamination (organic and inorganic mixtures) A, the most front-end membrane element gradually increased gradually increased slightly Mineral scale (Ca, Mg, Ba, Sr) […]

1, reverse osmosis membrane with anti-scale agent is designed for reverse osmosis (RO) system scale inhibitor, to extend the system cleaning cycle, the membrane life extension and reduce costs, to ensure that the system in accordance with the design of water production normal operation. Reverse Osmosis Membrane With Scale Inhibitor Features: (1) effective control of […]

With the development of pharmaceutical industry, the water quality of pharmaceutical water is also gradually increased, the traditional water process such as ion exchange method has been far from meeting its requirements, in order to meet the needs of this development, green water treatment company has advanced , Effective water purification technology – reverse osmosis […]

Cleaning and maintenance methods are as follows: 1, the physical cleaning method The simplest physical cleaning method is the use of low-pressure high-speed membrane into the water through the water for 30 minutes, which can make the membrane permeability to a certain degree of recovery, but a long time, water permeability is still declining, can […]

1 separation process without phase change, so save energy. 2 separation is carried out at room temperature, suitable for some heat-sensitive substances (such as fruit juice, pharmaceuticals, biological agents) concentration and purification. 3 series of ultrafiltration membrane, multi-component macromolecular solution system can be molecular weight grading. 4 equipment is simple, easy to operate and management […]

Dosing inhibition device role: mineral water equipment to prevent insoluble salt in the reverse osmosis membrane surface scaling. Softening is the use of ion exchange resin and water in the calcium and magnesium plasma exchange, the water calcium and magnesium ions removed. The advantage of softening is that the calcium and magnesium ions in the […]

(1) ultra-low voltage energy-saving series of composite membrane components. (2) low-pressure high-desalination chlorine series composite membrane components. (3) low-pollution series of composite membrane components. (4) desalination series of composite membrane components.

Reverse osmosis membrane protection A: (1) If the system short-term outage (1-3 days) of the protection method: A, before the outage, the first low-pressure system (0.2 ~ 0.4MPa), large flow (about equal to the system’s water production) rinse, time 15 minutes. B, to maintain the normal natural water, so that water flows into the dense […]

First turn off the instrument and turn off the water supply tap at the water inlet valve. Remove the reverse osmosis membrane shells at both ends of the fast-plugging water pipes – water pipes, water pipes, waste water pipes, pull out the attention of these three water pipes to distinguish, to prevent the installation of […]

Reverse osmosis membrane is the use of osmotic pressure principle, to the raw water added to a certain pressure, according to other substances can not be through the semipermeable membrane and the separation of these substances and water. As the reverse osmosis membrane pore size is only 10 Å, it can effectively remove the dissolved […]
