● 8040 reverse osmosis membrane: Due to its larger diameter, the surface area of ​​the membrane is usually between 365-400 square feet. ● 4040 reverse osmosis membrane: Due to its smaller diameter, the surface area of ​​the membrane is between 85-100 square feet.

In the water treatment industry, RO membranes are usually named in a combination of numbers and letters, which include the size and characteristics of the membrane element. For the 4040 RO membrane, "4040" represents the size of the membrane element

● High-end system: about $60,000 to $100,000. Includes complex pretreatment equipment, top-level reverse osmosis membrane, most advanced high-pressure pump and fully automated control system, suitable for applications with poor water quality or extremely high water quality requirements.

RO membrane cleaning can be achieved with a variety of chemical cleaners. These cleaners can be divided into three types: alkaline, acidic and neutral, each type has its own specific purpose and cleaning effect.

The average replacement cycle of RO membrane is 3-5 years. However, if the RO membrane is still able to produce high-quality water, you can extend its life beyond five years. Therefore, the frequency of membrane replacement depends on its operating conditions and water quality requirements.

The uniqueness of membrane filters in reverse osmosis systems lies in their micro pore accuracy, reverse osmosis principle, efficient desalination, water conservation and environmental protection, anti pollution, multi field applications, and technological innovation. Its high-precision micropores, reverse osmosis process, professional desalination, sustainable water conservation, and excellent pollution resistance are widely used in multiple fields.

Reverse osmosis membrane filters are widely used for drinking water purification, industrial wastewater treatment, medical water, seawater desalination, food and beverage, agricultural irrigation, and urban sewage treatment. The microporous structure effectively blocks harmful substances and ensures water quality safety.

Fouling and scaling on membrane filtration is one of the biggest challenge for ultrafiltration and reverse osmosis water treatment.
