Overview of Ultrafiltration Water Treatment System

In the process of ultrafiltration, aqueous solution under pressure, flow through the membrane surface, less than the membrane hole of the solvent (water) and small molecules of solute permeable membrane, become purification liquid (filtration liquid), than the membrane hole and solute group are trapped, with water discharge, become concentrated liquid. The ultrafiltration process is dynamic filtration and the separation is done in flow state. The solute deposits only on the surface of the membrane, and the ultrafiltration rate attenuates to a certain extent and tends to equilibrium, which can be recovered by cleaning.

Ultrafiltration is a pressurized membrane separation technology, that is, under a certain pressure, the small molecule solute and solvent through a certain aperture of the special film, and the large molecule solute can not pass through, stay at the side of the membrane, so that the large molecule material has been partially purified. Ultrafiltration is one of membrane separation technologies driven by pressure. Separation of large and small molecules for the purpose.

Technical specifications of Ultrafiltration Water Treatment System

Definition of Ultrafiltration Water Treatment System

Ultrafiltration is a hollow fiber filtration technology, with three stage pretreatment filtration to remove impurities in tap water; Ultrafiltration micropores less than 0.01 micron, can thoroughly filter bacteria, rust, colloid and other harmful substances in the water, retain the original trace elements and minerals in the water. Ultrafiltration membrane is an asymmetric semi-permeable membrane made of macromolecular materials. As a means of solution separation without phase transformation, ultrafiltration membrane can remove particles with molecular weight in the range of 1500-100000 Dalton, and can effectively remove organic matter, bacteria, viruses, colloid and non-ionic suspended solids.

Workflow of Ultrafiltration Water Treatment System

Raw water → original water tank (supplied by the buyer)→ raw water pump → disc filter → activated carbon filter →5μm security filter → ultrafiltration device → pure water tank (supplied by the buyer)→ water supply point

Ultrafiltration Water Treatment System filtration four steps:

1. Sand filter: use 0.5-1 mm sand medium. The filter can be as small as 200 microns in size. Some large suspended solids such as suspended solids, rust, mud, impurities, etc. can be trapped by the medium bed. And removed from the water.

2, activated carbon filter: can absorb some organic matter, dissolved air, smell and color substances.

3, micron filter: use 5-20 micron precipitate cartridge filter/bag filter, remove the suspended solid through the pretreatment. So the RO entrance is more secure.

4. Ultrafiltration system (UF membrane intercepts most ions. Demineralization/desalination, etc. The output will be pure water.

Components in an Ultrafiltration Water Treatment System

1. Water tank: store tap water, solve the problem of insufficient tap water pressure and the rear booster pump affected by insufficient water, reduce the failure rate

2. Booster pump: equipped with stainless steel pump to provide sufficient pressure for subsequent filtration.

3. Quartz sand filter: mainly remove sediment, suspended matter and large particles in tap water.

Activated carbon filter: mainly to remove organic matter, residual chlorine and odor in tap water.

5. Water softener filter: mainly remove calcium and magnesium in tap water, reduce the hardness of water.

6. Security filter: further filter to protect the late ultrafiltration membrane.

7. High pressure pump: provide sufficient pressure for the ultrafiltration system.

8. Ultrafiltration device: the core part of micro water making equipment, producing mineral water.

9. Mineral water box: when storing mineral water, the size of the water tank can be changed. After the following treatment, the water is pure and can be used for any needs.

Characteristics of Ultrafiltration Water Treatment System

Ultrafiltration water treatment system has low energy consumption, short production cycle, low operating cost compared with traditional process equipment, which can effectively reduce production cost and improve economic benefits of enterprises.

Ultrafiltration technology has the advantages of simple operation, low cost, no need to increase any chemical reagents, especially the experimental conditions of ultrafiltration technology is mild, compared with evaporation, freeze drying, no phase change, and does not cause temperature, pH changes, so it can prevent the degeneration, inactivation and autolysis of biological macromolecules. In the preparation of biological macromolecules, ultrafiltration is mainly used for desalination, dehydration and concentration of biological macromolecules. Ultrafiltration method also has some limitations, it can not directly obtain dry powder preparation. For protein solutions, concentrations of 10 to 50% are generally obtained.

Direction of Electrical Control System:

1 PLC(programmable logic controller): according to the need to design the program.

Air switch: protect electrical system

3 automatic controller, RO film can automatically wash.

Components: There are several consumables that you need to replace regularly. (1,000 miles per hour)

A. Quartz sand: replaced approximately every 15 months. 100kg/bag

B. Activated carbon: Replace it approximately every 15 months. 25kg/bag

C. Resin: Replaced approximately every 15 months. 25 l/bag

D. Polypropylene cartridge: replace approximately every month, 20 "x 5um

E. Ultrafiltration membranes: replace them approximately every year

We recommend that you buy 1-2 years of consumption PP filter element together with the machine. Because these PP filter elements need to be replaced every month, to avoid the breeding of bacteria on its surface.
