Water Treatment System

Overview:

Reverse osmosis process uses semi permeable spiral wound membranes to separate and remove dissolved solids, organic, pyrogens, sub micron colloidal matter and bacteria from water. Feed water is delivered under a pressure of approximately 16 kg/cm2 through reverse osmosis membranes. Water permeates the minute pores of the membrane and is delivered as purified water. Impurities in the water are concentrated in the reject stream and flushed to drain. Reverse osmosis is capable of removing 90-99% of total dissolved solids (TDS), 99% of organic, including pyrogens and 99% bacterial in the feed water.


Application: 

Raw water - raw water tank - raw water pump - sand filter - carbon filter - softener (optional) - security filter - 1 stage high
pressure pump - 1 stage reverse osmosis system - 2 stage high pressure pump - 2 stage reverse osmosis system - pure

water tank - UV sterilizer / ozone generator (optional) - water supply points

Function

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 /quartz sand filter /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

Security filter /pp filter / sediment filter

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


6

High pressure pump

Provide needed working pressure for RO system, ensure production   capacity of pure water.

CNP pump, Grundfos optional

7

RO (reverse osmosis) system

Can remove particles, colloids, organic impurities, heavy metal ions,   bacteria, virus, heat source etc. harmful substances and 97% dissolved salts.

RO membranes USA Filmtec Dow

8

UV/ Ozone generator

Kill bacterial in water. UV for direct drinking water. Ozone generator   for bottle water
