Cleaning generally uses backwashing, so what are the specific steps? Let's take a look!
Manual backwash operation method of laboratory pure water equipment
1. First stop the pure water lift pump, coagulant, coagulant metering pump, and then close the water inlet electric valve.
2. Manually open the two electric valves A and B of the electric return valve in the laboratory pure water equipment to drain water.
3. Manually open the backwater inlet electric valve of the laboratory pure water equipment, start the backwater pump, and after backwashing for about 5.0 minutes, stop the backwater pump and close the backwater inlet electric valve.
Remote control of automatic backwashing of laboratory pure water equipment
1. The laboratory pure water equipment is backwashed according to the cumulative running time of about 8 hours (the time can be adjusted, but it needs to be staggered with the time of the pure water equipment) .
2. First stop the laboratory pure water equipment pump, stop the operation of the coagulant and coagulant metering pump - close the electric valve at the entrance of the laboratory pure water equipment - open the drain A, B electric valve drain for about 60 seconds, close - open The backwash water inlet electric valve starts the backwash pump to flush for about 5 minutes, stops the backwash pump, and closes the backwash water inlet electric valve.
