Six Features of Scale Inhibitor for Reverse Osmosis Membrane

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 […]

Application of reverse osmosis membrane technology in pharmaceutical industry

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 method of reverse osmosis membrane

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 […]

Membrane separation characteristics

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 […]

Reverse osmosis membrane protection

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 […]

How to use the reverse osmosis membrane?

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 […]

Reverse osmosis membrane fault diagnosis

1, in the normal pressure such as product water flow down to 10-15% of normal. 2, in order to maintain the normal product water flow, the temperature correction after the water pressure increased by 10-15%. 3, the product water quality reduced 10-15%; salt permeability increased by 10-15%. 4, the use of pressure increased 10-15%. 5, […]
