3 Operating Guide

The water supply pressure should be at30-60Gradually increase within the time range of seconds;

The flow rate value should be within15-20Gradually rise to the design cross-flow within seconds;

3) The product water within the first hour should be discharged and not used.

4) Back pressure on the water production side of the membrane element should be avoided at all times.

4 General Information

1) Each membrane element is equipped with a concentrated water sealing ring, a connection adapter and the corresponding ones when leaving the factory O

Ring shape. The specific content is subject to the actual product.

Once a component is moistened, it should always remain moist.

When the system is shut down for a long time, the membrane elements should be immersed in the protective solution to prevent the growth of microorganisms. Standard preservation solution

containing 1.0％Sodium bisulfite (food grade) by weight

Users should avoid using any chemical agents that may affect the membrane elements. If such chemical agents are used in violation of regulations,

Beijing Enterprises Water Group Separation Membrane Company will not be responsible for the warranty.

: EDI ultra-pure water system

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.

: Non-negative pressure water supply equipment

The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.

: Constant pressure water supply equipment

Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
