What are the advantages of dual stage reverse osmosis pure water equipment?
Release time:2022-12-15
Reverse osmosis is divided into first and second stages, and different treatment schemes produce different water qualities. For the first and second stage water treatment equipment that appear on the market, what are the specific differences between the two? Many people still have doubts. Below, the editor will take you to understand the differences between first and second stage reverse osmosis, and what are the advantages of two-stage reverse osmosis equipment?
Firstly, reverse osmosis equipment is divided into three parts: pre-treatment system, reverse osmosis equipment, and post-treatment system, which adopt segmented and hierarchical processes.
Secondly, the pre-treatment system is mainly customized based on the water quality of the raw water. If the hardness of the raw water is high, it needs to be treated before entering the reverse osmosis system.
The reverse osmosis system is divided into first stage and second stage (dual stage). The first stage of reverse osmosis pure water uses the effluent from a single-stage reverse osmosis unit, and the water quality after the effluent from the single-stage reverse osmosis unit is subjected to secondary desalination treatment, which is called dual stage reverse osmosis water treatment.
The post-treatment system is to disinfect the water quality treated by the reverse osmosis system before the water point is used.
The advantages of dual stage reverse osmosis are:
The refinement of water treatment systems: Pure water equipment can achieve deep filtration of water by increasing the pressure on the water. In addition to general filters, the system also has fine filters, granular activated carbon filters, and compressed activated carbon filters.
High water utilization rate: Reverse osmosis uses extremely small pore size filtration membranes, which can separate water into higher and lower concentrations. After treatment, water with higher concentrations can be recycled and reused.
