Working Principle of quartz sand filter? The raw water usually contains dust with fine particles,Humic,Starch,Cellulose and microorganisms such as bacteria and algae.These impurities form colloidal particles in the Sol state with water,Due to the electrostatic rejection of the Brown motion, the settlement stability and polymerization stability are presented,Usually, it cannot be removed by the method of natural settlement under gravity,The general raw water pretreatment can destroy the stability of the Sol by adding a flocculation agent,To make small colloidal particles,And then it will become larger particles,Pre-filtration by sand filter and carbon filter,To remove these particles.Working Principle of quartz sand filter for groundwater it uses quartz sand as filter medium,Under certain pressure,The water with high turbidity is filtered through granular or non-granular quartz sand of a certain thickness,Effectively intercept and remove suspended matter, organic matter, gum particles, microorganisms, chlorine

The operation of ship oil-water separator is now widely used The general oil-water separation is the working principle composed of pre-filter, gravity separator, high efficiency agglomeration separator, adsorption filter. The picture is the specific process.As for how to operate, this kind of oil-water separation produced by our company is automated, which can realize unmanned duty, low labor intensity and simple operation.The separation of ship oil and water is generally two levels. The first is the separation of gravity, that is, the separation of surface oil depends on the different proportion of oil and water. Then there is the polymerization separation, which uses the polymer filter element to filter and separate the oil fraction of small molecules. In detail, you can download the relevant schematic diagram and operation instructions on the website of the equipment manufacturer. The design of each manufacturer is different and different. generally, it is gravity separation, aggregation separation, fine
