How to select primary reverse osmosis equipment and secondary reverse osmosis equipment 

The reverse osmosis equipment is a basic water treatment equipment, which can further improve the water quality to meet the drinking requirements. There are two types of reverse osmosis equipment, namely, primary and secondary, and they are also very different when used. What is the meaning of single-stage and two-stage reverse osmosis of reverse osmosis coagulation sedimentation equipment, and what are the differences between them? Next, our manufacturer will take you to explore the secrets.

The reverse osmosis coagulation sedimentation equipment is used to transfer raw water through fine filter, granular activated carbon filter, compressed activated carbon filter, etc., and then through pump pressurization and reverse osmosis membrane to make the water with higher concentration become low concentration water. At the same time, it isolates all the impurities mixed in the water, such as industrial pollutants, heavy metals, bacteria, viruses, etc., so as to meet the specified physical and chemical indicators and health standards for drinking, and output to clean to pure water.

1. Single stage reverse osmosis coagulation sedimentation equipment

The primary reverse osmosis equipment is also called single-stage reverse osmosis. The raw water is sent to the reverse osmosis device through the pretreatment system, the precision filter, the high-pressure pump, and the directly produced water is called single-stage reverse osmosis.

The single-stage reverse osmosis equipment is also called the primary reverse osmosis equipment. The raw water is sent to the reverse osmosis device through the pretreatment system, precision filter, high-pressure pump, and then the directly produced water is called single-stage reverse osmosis.

Features of single-stage reverse osmosis coagulation sedimentation equipment: under the action of external pressure, single-stage reverse osmosis equipment can selectively penetrate some components in the solution, so as to achieve the purpose of desalination, purification or concentration separation; It can remove most of the ions in the water, as well as impurities such as micro particles, bacteria and organic matter in the water. It is an advanced and economical means of water treatment equipment at present.

Single stage reverse osmosis equipment is mainly used for users with good water quality or low water quality requirements.

The two-stage reverse osmosis coagulation sedimentation equipment is also known as two-stage reverse osmosis. The two-stage reverse osmosis preparation system uses tap water as raw water, which is first pretreated, security filtered, and then filtered by a precision filter, and then pressurized by a primary high-pressure pump to the primary reverse osmosis system. The water produced by the primary reverse osmosis is then pressurized by a secondary high-pressure pump to the secondary reverse osmosis system. The produced water is called two-stage reverse osmosis.

Features of two-stage reverse osmosis coagulation sedimentation equipment: it can remove particles, colloids, organic impurities, heavy metal ions, bacteria, viruses, heat sources and other harmful substances in water and 90% of dissolved salts. The desalination rate of the system can reach more than 90%. The two-stage reverse osmosis is mainly used by users with poor water quality or high water quality requirements.

The two-stage reverse osmosis equipment is also called two-stage reverse osmosis. The preparation system of the two-stage reverse osmosis equipment takes tap water as raw water, which is first pretreated, filtered by security filter, and then filtered by the precision filter, and then pressurized by the primary high-pressure pump to the primary reverse osmosis system. The water produced by the primary reverse osmosis is then pressurized by the secondary high-pressure pump to the secondary reverse osmosis system. The produced water is called two-stage reverse osmosis.

Features of the secondary reverse osmosis coagulation sedimentation equipment: it can remove particles, colloids, organic impurities, heavy metal ions, bacteria, viruses, heat sources and other harmful substances in the water as well as 97% of the dissolved salts, and the desalination rate of the system can reach 96~98%.

The two-stage reverse osmosis equipment is mainly used by users with poor water quality or high water quality requirements.

After our explanation, we have learned more about the single-stage and two-stage forms of reverse osmosis coagulation sedimentation equipment. I hope we can provide constructive suggestions for your application selection, so that you can choose the reverse osmosis equipment you need.
