With the hot situation of swimming events in Beijing 2008 Olympic Games, the popularity of swimming pools and the improvement of the grade, some can meet the requirements of higher water quality and more advanced energy-saving new technology, new equipment, new technology, is gradually put into use in more and more swimming pools. Whether the newly built swimming pool (natatorium) or the swimming pool is still in the renovation of the pool are facing the problem of how to choose a good pool water circulation filtration.
The characteristics of diatomite determine its application field. Diatomite is characterized by high voidage, low density, large specific surface area, incompressibility, good chemical stability, non-toxic and tasteless. It is an excellent filter auxiliary material. Domestic filtration technology in sewage treatment, beer, food and beverage filtration have a wide range of applications
In foreign countries, diatomite filtration technology and equipment has been widely used in the circulating water treatment system of swimming pools. Due to the strong adsorption of diatomite filter aid, it can absorb water 1.5-4 times its own mass. Its potential is negative, its absolute value is large, and its ability to absorb positive charge is strong. Because of their huge specific surface area and surface adsorption and so on, take off a stable colloidal vulnerable to adsorption onto diatomite, and adhesion between the diatomite particles of pollutants in the mutual adsorption capacity is big, so refined modified diatomite is used for water treatment, can quickly form larger flocs, granularity and density and the stability of flocs is good, even when the flocs were broken, also can happen again flocculation. Filter aid is this other aluminum salt, iron salt, such as common wastewater of flocculant can not reach, diatomite huge specific surface, strong adsorption and surface electrical properties, make its in the process of water treatment, not only can remove rubber particle state and posture of the pollutants, and can effectively remove chromaticity and exist in dissolved phosphorus (one of the leading cause of eutrophication pollutants) and metal ion, etc.
