The operation of water purification equipment to confirm is to prove that the equipment can meet the design requirements and production process requirements and into the actual operation of the test, Creative all the water treatment equipment are open, running the main work is as follows.
(a) water purification equipment system operating parameters of the test
① check the purified water treatment of the operation of each device. Check all the equipment one by one, such as mechanical filters, activated carbon filters, water softeners, RO hosts, distilled water machine operation is normal, check the voltage and current, large furnace steam, water supply pressure.
② Determine the parameters of the purified water equipment. Each device has different requirements, such as mechanical filters are mainly to remove suspended solids, activated carbon filters mainly to remove organic matter and chloride. Soft water equipment to remove Ca, My. Through laboratory analysis of the water quality at the inlet and outlet of each device to determine the removal rate of the device, efficiency, yield, to see if the design requirements. Water quality analysis of the indicators should be based on the nature and use of the purified water equipment equipment, can be compared with the parameters of the operating manual. Such as double-stage should be determined after the resistivity, flow, pH, Cl- and cation exchange resin grade, number, exchange capacity, regeneration cycle, and each regeneration dosage.
③ Check the pipeline, plug leaks, replace defective valves and seals.
④Check the water pump to ensure that the pump operates in the specified direction.
⑤ Check whether the valves and control devices work properly.
⑥ Check the heating and insulation of the storage tank, purified water can be stored at about 60 ~ 70 ℃.
(B) pre-test analysis of purified water quality
In the formal start of the purified water monitoring (verification) before the purified water quality test, in order to find timely solutions to the problem. Test items are mainly chemical indicators and microbiological indicators, measurement points can be selected in the deionizer (or reverse osmosis device, distilled water machine) at the exit.
Note: Core focus on creating value for customers, above we will have professional staff training!
