Operating precautions for pure water production lines

The pure water water plant plays a vital role in ensuring people's health. The process of selecting the water system is the basis for ensuring water quality. The pure water production line is an important device of the system, which is mainly divided into three parts: pretreatment, reverse osmosis device and fine treatment. The purpose of the system is to reduce the floor space, facilitate transportation and maintenance.

Advantage analysis of pure water production line :

1. Set up an online water quality detector to observe the water quality at any time.

2. The pure water production equipment adopts the stainless steel frame structure to achieve no dead angle for cleaning and no corrosion of the equipment.

3. After the machine is turned on, the device can realize the automatic flushing function of the membrane element, and the washing time can be adjusted in 2 to 10 minutes.

4. The system is equipped with a cleaning and maintenance system, which can regularly clean and maintain the equipment to prolong the service life of the reverse osmosis membrane.

5. The system has a wastewater return device, which can make secondary use of water, improve the utilization of water resources and save operating costs.

Issues to be aware of in the operation of a pure water production line :

1. Prevent the filter material from entering the reverse osmosis device: Select a suitable filter water outlet device to prevent the filter from leaking sand and leaking activated carbon; select a suitable activated carbon to prevent powder removal during use.

2. The large-scale pure water production line with tap water as the water source sets up an independent water supply system, which can ensure the stable operation of the water supply system and reduce the instantaneous impact on the whole water supply pipe network when the RO system starts and stops. When the RO unit draws water directly from the raw water pipe network, high and low voltage protection facilities should be installed, as most of the water pipe network pressure fluctuates greatly.

3. The compatibility between the agent and the agent should be considered first, and then the compatibility of the agent with the film material should be considered. For example, coagulants, coagulants, bactericides, reducing agents and scale inhibitors are often used in RO systems. Since colloids in natural water are generally negatively charged, positively charged cationic coagulants are typically used.

In order to prevent fouling of the RO device, the inlet of the RO is almost always considered to be a measure of adding a scale inhibitor, and these scale inhibitors are almost all negatively charged. Therefore, the cationic coagulant should be prevented from reacting with the anionic scale inhibitor to prevent the colloidal compound formed by the reaction from depositing on the membrane surface.

Whether the pure water production line can run normally for a long time is important for maintenance and careful maintenance of equipment, and the equipment is handy. Therefore, care should be taken not to damage the machine during the operation of the pure water production line.

The above points are extremely important in the use of the pure water production line, which is both the protection of the equipment and the guarantee of the production.
