Emergency water supply membrane equipment is a mobile integrated kits, which can be quickly transported to water supply and water supply through means of transport such as container trucks or small pickup trucks. Emergency water supply membrane equipment can be in the transport can reach the rivers and lakes and even ponds, surface water (including nuclear, biological and chemical weapons under contaminated water) for water treatment, but also dilute brackish water and sea water. Equipment-owned diesel generator set, can be widely used in a variety of base military operations, field operations, field operations, disaster relief and provide emergency situations in a variety of emergency water supply

Scope of application:

1．Remote, suburbs garrison, a variety of land, sea and air base drinking water;
2．Rapid response, deployment and various military operations direct drinking water;
3．All kinds of combat armored vehicles, chariot water;
4．Battlefield hospitals with water;
5．To cope with all kinds of emergencies, earthquake relief drinking water;
6．Biochemical weapons battlefield direct drinking water;
7．Large-scale oil exploration, water conservancy and hydropower construction, railway and other field operations drinking water.
 
Process flow

Raw water → submersible pump → flocculant dosing pump → flocculation sedimentation tank → pressurized pump → multi-media filter → UV disinfection → activated carbon filter → precision filter → ultrafiltration device → UV disinfection → storage tank

1, flocculation sedimentation: natural water containing a variety of suspended solids, colloids and dissolved substances and other impurities, so that the water showed turbidity, color, odor, adding water to the raw water flocculating agent to precipitate the raw water particles, flocculation sedimentation Part of the bacteria and dissolved substances, so that the water was initially clarified. Flocculants from the metering pump to join, according to different water flocculants can be adjusted by the metering pump.

2, multi-media filter: the original water contains iron, magnesium, sludge, dirt, suspended solids and other large particles (10 microns above the material), these substances make the water becomes turbid, plug the pipeline. In order to remove the above impurities, must be equipped with a variety of media in addition to iron, in addition to sand, also known as deep bed filter. In the filter above the first layer is activated carbon, followed by multi-layer particles of different sizes of garnet, manganese green sand, sand and gravel and other minerals. When the water passes through the deep bed filter, the impurities are retained in the filter, and the entire filter is gradually filled so that the water pressure through the filter is reduced. When the water pressure is reduced, the recoil filter is required. In the recoil, the media in the filter is cleaned and restored to its original performance. The water is reversed, the recoil causes the bed of the medium to lift up, and the impurities affixed to the medium are floating and washed away. When the whole process is finished, the medium is arranged according to the original level.

3, activated carbon: mainly used to remove chlorine or chlorine ammonia and 60-300 Dalton material, such as organic matter, inorganic, heat source, pesticides and industrial solvents, to protect the reverse osmosis membrane.

4, precision filter: filter in the hole with a diameter of 5-20 µm filter to remove suspended particles.

5, ultrafiltration device: ultrafiltration technology is widely used in water purification, solution separation, concentration, water purification and recycling areas of high-tech. Hollow fiber tube wall covered with micropores, pore size to the molecular weight of the material can be retained, the molecular weight cut up to several thousand to several hundred thousand. Raw water in the hollow fiber outside or cavity pressure flow, respectively, constitute the external pressure and internal pressure. Ultrafiltration is a dynamic filtration process, the material can be removed with the concentration of small exclusion, not to block the membrane surface, long-term continuous operation.
