Household RO Water Filtration Unit Introduction
The household RO water filtration unit is a miniaturized water filtration station. It is simple to connect water dispenser with drinking water pipeline directly, connect the tee-joint outlet of water dispenser with pressure tank, and connect rear active carbon with drinking water gooseneck tap. It consists of automatic water feeding system, 5μm PPF melt blowing PP fine filter element, CTO active carbon adsorbent filter and 5μm PPF fine filter + UDF coco shell particle active carbon adsorbent rear filter. The household RO water filtration unit is able to detect running water pressure and make judgment if there is water at the inlet. The water pump is protected as it runs only with water.

Features of RO Filtration System

No additive is used or chemical reaction is occurred during treatment and the water is drinkable directly.
Automatically make filtered water uninterruptedly with a constant water quality to avoid the risk of secondary contamination.
Self-regulate water making system in accordance with demand and energy is saved.
Simple maintenance, safe and reliable with low trouble.

Replacement of Filter Element

Type	Filter Element	Replacement Cycle
PPF precipitation element	1st filter element	3 - 6 months
CTO extruded active carbon	2nd filter element	6 - 12 months
UDF particle active carbon	3rd filter element	6 - 12 months
RO reverse osmosis membrane	4th filter element	12 - 24 months
T33 rear active carbon	5th filter element	12 - 24 months

The replacement cycle is for reference only as the service life of filter element is dependent on the raw water quality.

Function of Five Stages Filter Element

• 1st stage precipitation PPF filter element:
The pore size of 5μm melt blowing PP fine filter element is in conformity with FDA standard and can effectively remove coarse solid to prolong RO membrane service life.

• 2nd stage extrusion CTO active carbon:
It is in conformity with FDA standard to remove organic matters in water. It effectively removes fine foreign matters and micro particles to protect RO membrane from blocking and prolong its service life.

• 3rd stage particle UDF active carbon:
High adsorbent active carbon particles can remove chlorine, bleaching agent, pesticide and organic residue as well as peculiar smell and color.

• 4th stage RO reverse osmosis membrane:
The extra micro pore size of 0.1 ? together with reverse osmosis can remove virus, toxin and carcinogenic chloroform. The fine filtration can separate impurities from filtered water and make drinkable water.

• 5th stage rear coco shell particle active carbon:
It is located after pressure water tank. It removes peculiar smell and purifies the water further to obtain a sweet and delicious drinking water.
