Remark

1

Raw water tank

Store water, buffering pressure, overcome instability of supplying water by pipe, ensure to supply water stably and continuously for whole system

Customer provide for themselves, because big size will result in expensive freight.

2

Raw water pump or called booster pump

Provide needed pressure for every pretreatment filter

We can provide CNP pumps or Grundfos pumps

3

Mechanical filter or called quartz sand filter or sand filter

We use fiber glass or stainless steel vessel as housing, fill quarts sand, it can filter big particles impurities, suspended substances, colloids etc.

4

Activated carbon filter

We use fiber glass or stainless steel vessel as housing, fill activated carbon, remove color, odor, residual chlorine and organics substances.

5

Water softener, demineralizer, or called Na+ exchanger

Adopt cation resin to soften water, cation resin will absorb Ca2+, Mg2+(main elements for composing scale), reduce hardness of raw water, System can make resin intelligently regenerate, recycling

6

Security filter or pp filter, or called PP sediment filter

prevent large particles, bacteria, viruses into RO membrane, accuracy is 5µm,
