Water is the source of life. human daily life and industrial and agricultural production are inseparable from water. (1) in order to explore the process of 'water purification', a chemical Interest Group, (1) 1 add alum to the water sample and stir and dissolve it,After a period of quiet,Filter,Remove small solid particles. the main instruments necessary for filtration operation are: iron frame, Beaker, glass rod and funnel with iron ring;During the experiment, it was found that the operation was much longer than expected,The possible reason is that there are too many insoluble substances on the filter paper, bubbles between the filter paper and the funnel wall;2 Add activated carbon to the filter,Remove the color and odor in the water sample by its adsorption,The process is a physical change;(2) the hardness of water can be reduced by heating the boiling method in life,Calcium carbonate carbon dioxide water,Is more and more,So it belongs to the decomposition reaction;The solubility of calcium bicarbo

What is KDF doing? What material? 20 Abstract: The properties of high purity copper zinc alloy kaidefei (KDF) are introduced,Kaidefei (KDF) is a high purity copper/zinc alloy particle,It is oxidized by micro-electrolysis-The reduction reaction (Redox) is used for water treatment,In contact with water,The two metals in the alloy form countless small primary battery systems on a submicroscopic scale,This material has a strong reaction ability and extremely fast reaction speed in water,It can remove up to 99% of chlorine in water and metal ions and compounds such as lead, mercury, nickel, chromium dissolved in water.It has an outstanding effect on the growth of bacteria, fungi, dirt and algae.It is used for pretreatment, main treatment and wastewater treatment equipment.KDF improves or replaces existing technologies,The system life can be extended by large convergence,Reduce heavy metals, microorganisms, dirt,Reduced the total cost,Maintenance of reduced s
