500LPH Two Stage With EDI System And Polished Mixed Bed For
Semiconductor Output to 18MΩ
System Advantages
√. Main part (membrane) of reverse osmosis system is imported from
USA.
√. Auto stop when no water and full water.
√. Auto controller, RO membrane auto flush to protect membrane.
√. Auto start when pure water tank have no water.
√. Low pressure protection switch to protect high pressure pump
when there is no raw water.
√. High efficient and low noise high pressure pump.
√. Product water conductivity meter to monitor product water
quality all the time.
√. Input water and output water pressure gauge to monitor RO
membrane
√. Differential pressure to remind it's time for chemical cleaning.
√. Inlet water solenoid valve to stop water when machine is stop.
Two stage RO system
This water treatment system uses mechanical filters, activated
carbon filter as a pre-class treatment, the effective removal of
suspended solids in raw water, sediment particles , organic
colloids, organic matter, odor, chlorine and other impurities, with
pre-programmed as a reverse osmosis desalination plant to remove
the raw water. Most of the dissolved salts, bacteria, hot stream
and so on, to ensure finished water quality standards.
If raw water conductivity is less than 300uS/cm, first stage output
is less than 10uS/cm, two stage output is 2uS/cm
EDI system
EDI, also known as electric desalination. It is a new ultra pure
water technology which gradually developed in the 20th century. EDI equipment combined electro dialysis technology and
ion exchange technology. It is using the selectivity penetrate
function of anion and cation membrane and exchange function of ion
exchange resin, under direct current electric field to make ion
directed migration. Finally to make deep desalination of water. In
the same time, hydrogen ion and hydroxide ion which produced when
water ionize will regenerate ion exchange resin. So if use EDI
equipment, no need acid and alkali chemical to do any regeneration,
and it can produce ultra pure water continuously.
EDI input water must less than 10uS/cm, output water quality less
than 0.2uS/cm.
Polished mixed bed system
Polishing resins are generally used at the end of ultrapure water
treatment systems to ensure that the
system's effluent quality maintains water standards. Generally, the
effluent water quality can reach 18
megaohms or more. After the polishing resin fails, it is discarded.
Filled with resin, it can be used when
slowly passed through water.
Recycle water in pure water tank to minimize conductivity,
Resistivity more than 18MΩ.

Some parts function
| 1.Raw water pump: provide needed pressure for every pre-treatment
filter; |
| 2.Quartz sand filter: use fiber glass as housing, fill quartz sand,
it can filter big particles impurities, suspended substances,
colloids etc. Important to remove iron and sediments you mentioned; |
| 3.Activated carbon filter: use fiber glass as housing, fill
activated carbon, remove color, odor, residual chlorine and
organics substances; |
| 4.Security filter: prevent large particles, bacteria, viruses into
RO membrane, accuracy is 5µm; |
| 5.High pressure pump: provide needed working pressure for RO
system, ensure production capacity of pure water; |
| 6.RO system: can remove particles, colloids, organic impurities,
heavy metal ions, bacteria, virus, heat source etc. harmful
substances and 99% dissolved salts. |
