What is the Nano effect? Nano is the unit of length,Originally called millimicron,Is 10 ^-9 m (one meter per 1 billion ).Nano Science and Technology,Sometimes referred to as nanotechnology,It is to study the properties and applications of materials with structural dimensions in the range of 1 to 100 nm.Nano-effect means that nano-materials have strange or abnormal physical and chemical properties that traditional materials do not have,If the originally conductive copper does not conduct electricity to a certain nano-scale boundary,The original insulating silica, crystals, etc,Start conducting at a certain nano-scale boundary.This is due to the small particle size, large specific surface area, high surface energy, large proportion of surface atoms, etc,And its unique three effects: surface effect, small size effect and macro quantum tunnel effect.The surface area of the spherical particles is proportional to the square of the diameter,Its volume is directly proportion
Ask for a plan book about removing iron and manganese filter Many towns and industrial and mining enterprises in China use groundwater as water source.However, there is an excess of iron in groundwater in many areas,Its content is generally 2-16mq/L range.'Automatic iron and manganese removal filter' overcomes the human operation,Various problems caused by backwashing,Give full play to the special features of fully automatic work,Therefore, it has incomparable superiority in other iron removal devices,The iron content of groundwater after treatment is ≤ 0.3 mg/L,National GB5749-85 quality standards for drinking water.In addition to iron and manganese in water,Make the oxygen in the air two-valent iron,Oxidation of manganese at two prices,Generate Fe (OH) 3,Manganese dioxide,According to the content of iron and manganese in water,Jet aeration or hollow multi-face ball aeration are selected.Filter with first-class or multi-stage manganese sand filter,Can meet the processing requirements,Eff
