Pressureless Ultrafiltration Membrane

Rainwater filtration is very popular in water treatment technology, There are many places in the world. Rainwater has been collected since ancient times, and reservoirs have been built. It has been preserved to this day. The use of rainwater has promoted the development of many ancient civilizations in the world. And it is very consistent with today’s concept of sustainable development of the whole world. Collecting and using rainwater as an important water resource, and implement comprehensive management to play a positive role.

1. The rainwater collecting pipe of the eaves is connected to the water tank.
2. As long as there is water in the water tank, open the water tap to get clean and clean drinking water (mineral water level).

Layer 1: Outer screen type protective housing, UPVC/OPVC cage with 1-2mm gap size.

Layer 2: The microfiltration layer is ultra-hydrophilic PP cotton, the average aperture size of the microfiltration layer is between 2 to 200 micron.

Layer 3: The carbon fiber adsorption layer is made up of antibacterial modified carbon fiber in a diameter range from 1 to 100um.

Layer 4:  Outer screen type protective housing, UPVC/OPVC cage with 1-2mm gap size.

Layer 5: The ultrafiltration membrane filter layer may be polyfluoroethylene, polyurethane, polyether, polyvinyl chloride or poly-acrylic

The water filter tank is equipped with a gravity water purification, it includes the ultrafiltration filter, which is screwed near the side, and there is a water tap at membrane module cover, which is fixed outside of the receiver tank.

As a preference, one side of the tank is equipped with a level control valve for the water level control, and the level control valve is equipped with a float for detecting the level. Besides, the height of the float is 2 to 8 times the outer diameter of the membrane module, here select 1-2m for running. As a preference, the bottom of the tank is equipped with a discharge valve for the removal of residual dirt mud.
