Quartz sand plays a more and more important role in water treatment, removing suspended solids plays a filtering role. As a technical means, when using in any water treatment project, you should first understand some of its characteristics and technical indicators. The following is a brief description of its application in water treatment from the characteristics of quartz sand filter material itself and the operation process of quartz sand filter.

Quartz sand filter material is a kind of water treatment filter material made of natural quartz ore through crushing, washing, screening, pickling, drying and secondary screening; The main components of quartz sand are silicon dioxide , containing ferric oxide 、 clay And impurities in agricultural production system. Quartz sand filter material has the characteristics of multi prism and spherical appearance, pure white, high hardness, good corrosion resistance, high density, high mechanical strength, and long service life of pollution carrying capacity line. It is an ideal material for chemical water treatment. It is applicable to single-layer and double-layer filters, filters and ion exchangers, and all indicators meet the (CJ/T43-1999) standard.

Quartz sand filter material plays a filtering role, just like water passing through sand When it penetrates into the ground, it blocks the suspended substances in the water, mainly focusing on the fine suspended substances. The quartz sand is used as the filter material. The quartz sand is combined with the filter container to intercept the suspended solids, colloid and other particulate impurities in the water, so as to play the role of filtration.

Working principle of quartz sand filter material

In the process of quartz sand filtration, the removal of suspended particles is mainly due to the adsorption and adhesion between particles and filter materials and between particles. This involves two principles: the suspended particles carried by water move forward and move away from the flow line to the surface of the filter material

Migration mechanism; The second is that when suspended particles contact with the filter material, they are adhered to the surface of the filter material by some or several forces (including van der Waals force, surface tension and coulomb force), which is the adhesion mechanism of particles. In this mechanism, to ensure the quality of filtered water, a certain surface area of the filter material of the filter layer is guaranteed, Provide sufficient adsorption space for suspended particles to be adsorbed on the surface, so that suspended particles can be effectively adsorbed on the surface of filter material. The migration and transportation of suspended particles in the water flow in the filter layer gap is a process of sedimentation, inertia, interception, diffusion, dynamic effect and other basic functions. As for the role of the particles, which force depends on the size of the turbidity particle size. In the filtration process, the surface area of the filter material plays a more important role. The larger the particle surface provided by the filter material, the stronger the adhesion to the suspended solids in the water. In order to achieve a certain expected effluent quality, the surface area provided by the filter material should meet a small value.

Classification of quartz sand filter material Quartz can be divided into ordinary quartz sand, refined quartz sand, high-purity quartz sand and fused quartz sand according to quality. But in water treatment, there are only two kinds, ordinary quartz sand filter material and refined quartz sand filter material, while refined quartz sand is suitable for pure water, and sewage treatment is generally only used with ordinary quartz sand. Ordinary quartz

In sewage treatment, it can be used for three or five years, as long as the loss of quartz sand is prevented, even if it is polluted, it is not important, because in sewage treatment, sludge can carry out aerobic or anaerobic respiration to degrade pollutants in sewage.
