How to make artificial sea water? Artificial seawater is prepared close to the ion composition, osmosis pressure and pH like seawater,There are recipes such as Herbst and Vant Hoff.Because the seawater pressure can vary from region to region (the pressure on the Mediterranean coast is higher than that on the Japan Pacific Coast and the United States Atlantic coast ),Therefore, artificial seawater should also use different penetration concentrations according to the region.When preparing artificial seawater,It is usually first made into a solution of NaCl, potassium chloride, CaCl 2, MgSO 4 (MgCl 2) with penetration concentration such as seawater,Then mix these solutions according to the appropriate dissolution ratio,Then change the mixing ratio,Assuming that a certain score is removed,It can be used to study the physiological effects of specific metal ions in seawater.Step one,Just put the water,If there is no old water (after drying the water to remove chlorine ),Tap water is also available,For 7 da

Which filter element for reverse osmosis security filter is good for fusion spray and wire wrap? The fusion filter element is a tubular filter element made of non-toxic and tasteless polypropylene particles, heated and melted, sprayed and towed. Reverse osmosis generally uses a 5 micron aperture. The Wire wrap filter element of the melt spray filter element is made of textile fiber. according to the specific process, it is tightly wound on the porous skeleton, the filter element that forms the outer dense honeycomb structure. The advantage is that the service life is long, it is not easy to suck flat, and it is easy to clean. The disadvantage is that the filter aperture is uneven, and the water quality is not ideal due to the pressure effect. The above is just a comparison of these two filter elements. Personally, it is recommended that the fuse filter element is better and the water quality is the key.Technology Department of Dongying Xingjie water treatment equipment Co., Ltd.The price of the fusion spray
