● I、Overview of Application：
Acid ammonia, metal tungsten powder, such as tungsten rods of tungsten metallurgical industry:Ammonia acid molybdenum, vanadium molybdenum metal metallurgical and other precious metals
●II、a typical process flow
Pretreatment System - Reverse Osmosis System - middle cisterns - coarse mixed Machine - fine hybrid machine - pure water - pure water pumps - ultraviolet sterilizers - polishing mixed bed - Jingmiguolu:qi - like water（≥18MΩ.CM）(traditional technology)
Pretreatment - reverse osmosis - middle cisterns - pumps - EDI devices - purified water tanks - pure water pumps - ultraviolet sterilizers - polishing mixed bed -0.2 or 0.5 μ m Jingmiguolu:qi - water Objects （≥18MΩ.CM）(the latest technology)
Pretreatment - a reverse osmosis - Dosing Machine (PH adjustment) - Middle cisterns - second-class reverse osmosis (positive charge anti-permeability membrane) - pure water - pure water pumps - EDI devices - ultra-violet disinfection of -0.2 or 0.5 μ m precision Filters - water Objects（≥17MΩ.CM）(the latest technology)
Pretreatment - reverse osmosis - middle cisterns - pumps - EDI devices - pure water - pure water pumps - ultra-violet disinfection of -0.2 or 0.5 μ m Jingmiguolu:qi - water Objects（≥15MΩ.CM）(the latest technology)
Pretreatment System - Reverse Osmosis System - middle cisterns - pure water pumps - coarse mixed Machine - fine hybrid machine - ultraviolet sterilizers - Jingmiguolu:qi - water Objects （≥15MΩ.CM）(traditional technology)
●III、Standard reference
CRT, LCD monitors water quality with pure water （empirical data）
Water quality integrated circuits with pure water
The electronics industry to use national pure water standards
●IV、Equipment Features
To meet user needs to comply with the water quality standards, as far as possible to reduce the levels of pollution, extend the life of equipment and reduce operator maintenance workload. In process design, the admission of the national water standards for water source water, a media filters, activated carbon filters, sodium softening, Jingmiguolu:qi such pretreatment systems, RO reverse osmosis mainframe systems, mixed bed ion exchange (EDI, demineralizing system) system.
Water tanks are equipped with System Level Control System, pumps are equipped with pressure protection devices, online testing water quality control instruments, and electrical use PLC programmable logic controller so that they could really no duty, while studies in technology and customer use recommended asked unity means for the equipment and other similar products, compared to a higher price, performance and equipment reliability.
