The EDI ultra pure water equipment is composed of two systems: desalination and extraction, where the anion and cation exchange membranes are replaced and sorted between the positive and negative electrodes, and separated by special baffles. When salt water enters the compartment, under the influence of a DC electric field, positive ions transfer to the negative electrode and can only rely on a cation exchange membrane. Cations transfer to the anode and can only rely on an anion exchange membrane, so that the salt water in the dilution chamber is diluted and the salt water in the concentration chamber is extracted. Below, the editor will take you to understand how to properly maintain EDI ultra pure water equipment.

Maintenance and upkeep of pre-treatment

The pre-treatment section mainly consists of sand filters, carbon filters, and water softeners. In the pre-treatment section of Tianyuan Water Treatment, manual (automatic) multi way valves are generally used. This multi way valve is easy to operate and easy to learn and use. After using the sand filter and carbon filter for a period of time, the surface of the sand carbon will accumulate some large particles such as sediment impurities and colloids. Therefore, we suggest that after 3-7 days of equipment use, the sand filter and carbon filter should be backwashed to break through the impurities on the surface of the sand layer and carbon layer, in order to improve the filtration effect. The function of the water softener is mainly based on the principle of ion exchange to reduce the hardness of water. Therefore, as the usage time increases, the softening ability of the cation resin gradually decreases, and NaCl needs to be used for regeneration.

Maintenance and upkeep of the reverse osmosis section

As a crucial component of the entire system, the reverse osmosis membrane requires even more careful maintenance. When planning the reverse osmosis system, it should have an automatic flushing function. During flushing, the pressure should not exceed 3KG and the flow rate should be fast. To flush away the dirt on the surface of the valve disc. The machines produced by Tianyuan Water Treatment have the above functions, which can automatically flush on time or manually. In addition, dedicated personnel should be assigned to observe and record the values of each instrument.

The automation level of water purification equipment is getting higher and higher, but it also depends on the maintenance of the equipment during use.
