What are the water treatment equipment in Jinan? RO-The pretreatment process of reverse osmosis is mainly activated carbon and fine filtration.Penetration is a natural phenomenon: water passes through a semi-permeable membrane,From the low solute concentration side to the high solute concentration side,Until the degree of solvent is balanced.When balancing,Membrane Pressure difference on both sides is equal to osmotic pressure.This is the phenomenon of infiltration effect (Osmosis.Reverse osmosis means that if it is pressurized on a high concentration side,The penetration effect mentioned above can be stopped and reversed,The water is forced from a high concentration to a low concentration,Water purification.This phenomenon is called reverse osmosis (reverse osmosis ),This semi-permeable membrane is called reverse osmosis membrane.Reverse osmosis water treatment equipment can filter out bacteria, viruses, heavy metals, pesticides, organic matter, minerals and color odor in the water,It's a pure water,Dri

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
