0.5 ton of unipolar reverse osmosis water treatment equipment for 3 tanks Treatment Machine Plant

Product Description

The reverse osmosis system is mainly composed of a pretreatment unit, a reverse osmosis unit and an electrical control unit.
Pre-treatment generally includes raw water pump, dosing device, quartz sand filter, activated carbon filter, precision filter and so on. Its main role is to reduce the pollution index of raw water and residual chlorine and other impurities, to achieve the reverse osmosis water requirements. The equipment configuration of the pretreatment system should be based on the specific conditions of the raw water.
The reverse osmosis unit mainly consists of multi-stage high-pressure pumps, reverse osmosis membrane elements, membrane shells (pressure vessels), brackets and other components. Its main role is to remove impurities in the water, so that the water to meet the requirements of use.
Electrical control unit is used to control the normal operation of the entire reverse osmosis system. It includes instrument panel, control panel, all kinds of electrical protection, electrical control cabinet and so on.

Parameter Table

Application

1, the preparation of electronic industrial production, such as picture tube glass shell, picture tube, liquid crystal display, circuit boards, computer hard disk, integrated circuits, chips, monocrystalline silicon semiconductor and other processes required for pure water, high purity water;

2, the preparation of thermal power, thermal power boilers, factories and mining enterprises in the low-pressure boiler feed water required for softening water, desalination of pure water;

3, the preparation of medical infusion, injection, pharmaceuticals, biochemical products required by the pharmaceutical industry, pure water, medical sterile water and pure water for artificial kidney dialysis;

4, the preparation of beverages (including alcohol) industry, drinking water, distilled water, mineral water, alcohol brewing water and blending with pure water;

5, seawater, brackish water to produce domestic water and drinking water;

Maintenance

1. Low-pressure flushing reverse osmosis device
Regular flushing of reverse osmosis device with high flow rate, low pressure and low pH value is conducive to stripping off the dirt adhering to the membrane surface and maintaining the membrane performance, or when the SDI of the inlet water of the reverse osmosis device suddenly rises above 5.5, it should carry out low-pressure flushing, and start up the device again after the SDI value has been adjusted to a qualified level.

2. Reverse osmosis device shutdown protection
Due to the fluctuation of production, reverse osmosis device inevitably often shut down, short-term or long-term shutdown must be taken to protect the measures, improper disposal will lead to membrane performance decline and can not be restored.

3. Reverse osmosis membrane chemical cleaning

Under normal operating conditions, reverse osmosis membrane may also be inorganic scale, colloids, microorganisms, metal oxides and other contaminants, the deposition of these substances on the membrane surface will cause a decrease in water purification equipment reverse osmosis device output or desalination rate, differential pressure increases, and even the membrane caused by the irrecoverable damage, therefore, in order to restore good water permeability and desalination performance, the need for chemical cleaning of the membrane.
General 3 ~ 12 months cleaning once, if every month had to clean once, which indicates that the pretreatment system should be improved, the adjustment of the operating parameters. If 1 ~ 3 months need to be cleaned once, it is necessary to improve the operation of the equipment, whether the need to improve the pretreatment system is more difficult to judge.
