250LPH Ro System Water Purifier Machine Filtration Equipment
Product Introduction of RO Water Treatment System
There are many pores on the reverse osmosis semi-permeable membrane, and the size of these pores is equivalent to the size of water molecules. Since bacteria, viruses, most organic pollutants and hydrated ions are much larger than water molecules, they cannot pass through the reverse osmosis semi-permeable membrane. The membrane is separated from the water phase passing through the reverse osmosis membrane. Among the many impurities in water, soluble salts are the most difficult to remove. Therefore, the water purification effect of reverse osmosis is often determined according to the desalination rate. The desalination rate of reverse osmosis is mainly determined by the reverse osmosis semi-permeable membrane selectivity. The salt removal rate of the reverse osmosis membrane element with higher selectivity can be as high as 99.7%.
The Basic Working Principle of RO Water Treatment System
1:Pre-treatment system
It mainly includes: raw water pump, quartz sand filter, dosing
device, security filter, precision filter. Its main function is to
reduce the pollution index of raw water and other impurities such
as residual chlorine, so as to meet the water inlet requirements of
reverse osmosis. The equipment configuration of the pretreatment
system should be determined according to the specific conditions of
the raw water.
2:Reverse Osmosis system
It mainly includes multi-stage high-pressure pumps, reverse osmosis
membrane elements, membrane casings (pressure vessels), pressure
instruments, flow meters, brackets, etc. Its main function is to
remove impurities in the water and make the effluent meet the
requirements of use. According to water requirements, a
single-stage reverse osmosis device or a double-stage reverse
osmosis device can be used.

Advantages of RO water treatment system:
Reverse osmosis (RO) technology is a highly efficient and
energy-saving technology. It relies on pressure to separate water
and ions, so as to achieve the purpose of purification and
concentration. The process has no phase change, generally does not
require heating, low energy consumption, low operating cost, no
pollution, convenient and reliable operation, high water quality
and many other advantages. It has become an energy-saving
technology for seawater and brackish water desalination. Has been
widely used in medicine, electronics, chemical industry, food,
seawater desalination and many other industries. Reverse osmosis
technology has become a water treatment technology in modern
industry. Reverse osmosis (RO) technology has become an important
part of membrane separation technology.
(1) Fresh water can be extracted from seawater or brackish water;
(2) It is easy to remove organic matter, bacteria, colloids and
other impurities dissolved in water to obtain high-purity water;
(3) Since the reverse osmosis process is a physical process without
phase transition, it saves energy;
(4) Simple operation, easy automation and labor saving;
(5) Compact structure and small footprint, thereby reducing costs;
(6) As a concentration method, it can recover valuable components
dissolved in the solution.
Process flow of RO Water Treatment System
