Matters needing attention when operating pure water equipment
Dec 17, 2018

When using pure water equipment, we should pay attention to what problems, and then we will introduce them in detail:


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. As far as possible, an independent water supply system should be set up for large-scale pure water equipment with tap water as the water source. This can ensure the stable operation of the water supply system and reduce the instantaneous impact on the water supply pipe network of the whole plant 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 limbs in natural water are generally negatively charged, a positively charged cationic coagulant is 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 film surface.
