3 tons of single-stage reverse osmosis equipment for Industrial Plating

Product Description

When the pure water and salt water are separated by an ideal semi-permeable membrane, the ideal semi-permeable membrane only allows water to pass through and prevent the salt from passing through, at this time the pure water side of the membrane water will spontaneously flow through the semi-permeable membrane into the brine side, this phenomenon is known as osmosis, if the brine side of the membrane to apply pressure, then the spontaneous flow of water will be inhibited and slowed down, when the pressure exerted by the membrane reaches a certain value, the net flow rate of water through the membrane is equal to zero, the pressure is known as the permeability of the pressure. Pressure, when the pressure applied to the brine side of the membrane is greater than the osmotic pressure, the flow of water will be reversed, at this time, the brine in the water will flow into the pure water side, the above phenomenon is the reverse osmosis (RO) treatment of water, the basic principle.

Key Advantage

1, reverse osmosis belongs to the physical desalination method, in many aspects with other different advantages.

2, operating at room temperature using a physical method without phase change will contain salt water for desalination, purification. At present, a single reverse osmosis membrane element up to 98% or more, and can simultaneously remove colloids in water, organic matter, bacteria, viruses and so on.

3, water pressure as a driving force, energy consumption in many treatment methods in the lowest.

4,No need for a large number of chemical treatment, no chemical waste discharge, no environmental pollution.

5, high recovery rate, up to 70% or more.

6, high degree of automation, automatic shutdown in case of failure, with automatic protection function.

7,Continuous operation of water production, the system is simple, easy to operate, stable water quality.

8, the equipment covers an area of small, compact structure, reliable operation, water quality and many other advantages.

Maintenance

1, security filter import and export pressure difference rises (﹥0.06Mpa), the filter element must be replaced to ensure the normal operation of the RO device. Filter element replacement cycle depends on the quality of its water inlet, generally every 15-20 days to replace a zui long replacement cycle should not exceed 30 days. After the cartridge replacement, the security filter must be exhausting water (exhaust process: open the upper exhaust valve of the filter, put your hand on top of the exhaust valve, close the exhaust valve when water comes out, and end the exhaust process).

2, regular periodic records of RO device various operating parameters.

3, equipment for a long time, RO membrane components will produce fouling, then the need for regular chemical cleaning of RO membrane components. Generally 10% increase in working pressure, feed water and concentrated water between the system pressure difference rises to 1.5 times the initial value of the water production decreased by 10%, water conductivity increased by 10% of any one of them as a chemical cleaning of the membrane as a reference signal, even if no abnormalities, in order to better ensure the normal operation of the system, generally can be considered every 6 months for a chemical cleaning.
