Emergency water supply membrane equipment is a mobile integrated kits, which c™an be quickly transported to water supply and water supply through means of transport s✔uch as container trucks or small pickup trucks. Emergency water s♣upply membrane equipment can be in the transport can reach the r$ivers and lakes and even ponds, surface water (including nuclear↑, biological and chemical weapons under contaminated water) for water treatment, but also dilute ®brackish water and sea water. Equipment-owned diesel generator set, can be widely used in a v≈ariety of base military operations, field operations, field operations, disaster relief and provide emergency situations in a variety of emerge↑ncy water supply
Scope of application:
1．Remote, suburbs garrison, a variety of land, sea and air base drinking water;
2．Rapid response, deployment and various military operations direct drinking water;
3．All kinds of combat armored vehicles, chariot water;
4．Battlefield hospitals with water;
5．To cope with all kinds of emergencies, earthquake relief drinking water;
6．Biochemical weapons battlefield direct drinking water;
7．Large-scale oil exploration, water conservancy and hydr∑opower construction, railway and other field operations drinking watΩer.
Process flow
Raw water → submersible pump → flocculant dosing pump → flocculation sedi$mentation tank → pressurized pump → multi-media filter → UV disi÷nfection → activated carbon filter → precision f'ilter → ultrafiltration device → UV disinfect∞ion → storage tank
1, flocculation sedimentation: natural water containing a variety of suspended solid∏s, colloids and dissolved substances and other impurities, so that the water sh₹owed turbidity, color, odor, adding water to the raw water flocculating aΩgent 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,λ according to different water flocculants can be adjusted by the metering pump.
2, multi-media filter: the original water contains i∞ron, magnesium, sludge, dirt, suspended solids and other large particles (10 microns above the mate'rial), these substances make the water becomes turbid, plug the pip•eline. In order to remove the above impurities, must be equipped with a variety of media in addition to iron, in addition to sand, also know♣n as deep bed filter. In the filter above the first layer is activated carbon, followe≠d 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 impu•rities are retained in the filter, and the entire filter is gradually filled so that the wa×ter pressure through the filter is reduced. When the water pressure is red uced, the recoil filter is required. In the recoil, th&e media in the filter is cleaned and restored to its original performance. The water iβs reversed, the recoil causes the bed of the medium to lift up, and the im≠purities affixed to the medium are floating and washed away. Whe♥n the whole process is finished, the medium is arranged according to the original level.
3, activated carbon: mainly used to remove chlorine or chlorine ammoniσa 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, solutσion separation, concentration, water purification and recycling areas of high-tech. Hollow fi∏ber tube wall covered with micropores, pore size to the molecular weight of the mΩaterial can be retained, the molecular weight cut up to several thousand to several hundred thπousand. Raw water in the hollow fiber outside or cavity pressure flow, respectively, constitute thδe external pressure and internal pressure. Ultrafiltration is a ←dynamic filtration process, the material can be removed with the concentration of small exclu→sion, not to block the membrane surface, long-term continuous operation.
