Flow Chart

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
STEP<1>. Sand Filter:  Use quartz sand media with a diameter of 2-4mm to remove some big suspended solids like colloids, rust, mud, impurity etc.  
STEP<2>. Carbon Filter:  Active carbon can absorb some organism, dissolved air, odor & color matter etc.
STEP<3>. Softener:  Use cation exchange resin to remove Calcium, Magnesium etc. to make soft water.
STEP<4>. Security Filter: Use 5 -20 micron sediment cartridge filter / bag filter, to remove the passed suspended solid from pre-treatment, so that to ensure the safety of the entrance of RO system.
STEP<5>. Reverse Osmosis: The nanometer RO membrane can intercept the inorganic salt, heavy metal ions, organic matter, colloid, bacteria, viruses and other impurities but H2O of the source water, so it can produce the pure water.

No.	Name	Function	Remark
1	Raw water tank	Store water, buffering pressure, overcome instability ofsupplying 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  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,  optional
7	RO(reverse osmosis) system	Can remove particles, colloids, organic impurities, heavy metal ions, bacteria, virus, heat source etc. harmful substances and 99.999% dissolved salts.	RO membranes USA Filmtec Dow
8	UV/ Ozone generator	Kill bacterials in water. UV for direct drinking water. Ozone generator for bottle water

Product Features

250lph reverse osmosis system for purifying tap water
Function of each part of water treatment plant 

1.feed water pump -- provide the pressure to quartz sand filter/active carbon filter

2.Multi-medium filter-- get rid of turbidity, suspended matter, organic matter, colloid, ect.

3.Active Carbon filter--Remove the color, free chloride, organic matter, harmful matter, ect. 

5.Security filter--prevent large particles, bacteria, viruses into RO membrane, accuracy is 5um

4.Softener--exchange "ions" of calcium and magnesium with the most common and easiest method. 6.High pressure pump-- Provide the high pressure to RO membrane 

8.UV sterilizer or ozone generator--- kill bacteria

7.RO system-- main part of the plant. The RO membrane's desalting rate can reach 99%, removing over 99% ions
