reverse osmosis equipment

Introduction to reverse osmosis equipment configuration

1. Pre treatment of reverse osmosis equipment

Composed of a multi-media filter, activated carbon filter, and fully automatic water softener.

Multi media filter: It is composed of fully automatic control valves, fiberglass tanks, and quartz sand with different grading ratios. The suspended solids and some colloidal substances in the raw water reduce the turbidity of the raw water. And it can automatically perform backwashing.

Activated carbon filter: It is composed of a fully automatic control valve, a glass jar, and activated carbon of different water purification grades. Adsorb harmful substances such as heavy metals, free chlorine, chloroform, etc. from raw water. And it can automatically perform backwashing.

Softener: It is composed of a fully automatic control valve, fiberglass tank, and resin. Remove calcium and magnesium ions from water through a water softener. Ensure that the reverse osmosis equipment operates without affecting the service life of the reverse osmosis membrane due to scaling. And it can automatically perform ZS.

2. Reverse osmosis equipment host part

The host of the reverse osmosis water purification equipment mainly consists of a security filter, a high-pressure pump, a reverse osmosis membrane, and various control and display instruments.

Security filter: Security filter provides protection before raw water enters the membrane. It can remove substances larger than 5 μ m leaked during pre-treatment. The main purpose is to prevent suspended particles from entering the reverse osmosis membrane element, depositing on the membrane surface and contaminating the membrane element.

High pressure pump: provides the required pressure for reverse osmosis, ensuring the separation of solvents and solutes. High pressure pump is one of the key components of reverse osmosis equipment.

▼ Reverse osmosis membrane assembly: The reverse osmosis membrane assembly is composed of polymer fibers with a highly ordered matrix structure. Its pore size ranges from 1-10 angstroms, which is equivalent to one thousandth of a meter to one billionth of a meter (equivalent to one sixth the size of Escherichia coli and one third the size of a virus). Utilizing the separation properties of reverse osmosis membranes, it removes impurities such as dissolved salts, colloids, organic matter, heavy metals, trihalomethanes intermediates produced by chlorination, and microorganisms from the solvent.

▼ Reverse osmosis membrane shell: used to accommodate reverse osmosis membrane elements, under pressure and creating a high-pressure environment for reverse osmosis operations.

▼ Flow meter: Pure water flow meter and concentrated water flow meter respectively measure the instantaneous flow rate of RO pure water and concentrated water.

Pressure gauge: measures the water pressure at various locations of the reverse osmosis equipment.

Concentrated water regulating valve: used to regulate the operating pressure, pure water and concentration ratio, and pure water production of RO equipment.

Conductivity meter: monitors the conductivity of reverse osmosis effluent.

▼ Low pressure switch: prevent the RO high-pressure pump from idling or working under low pressure.

Liquid level controller: It automatically stops or starts the reverse osmosis equipment based on the liquid levels of the raw water tank and the pure water tank.

▼ Electric control system: including conductivity meters and other instruments and control equipment, it is the control center of reverse osmosis equipment.
