We use circulating water scaling agent under normal circumstances will have corresponding to the specific form of expression, when used, we can according to the form to analyze and make appropriate adjustments to the current situation, if there are other substances hinders the circulating water scaling agent dispersed, the influence to play its role. Then we will think of a way to the pulled out. 1, circulating water scale inhibitor concentrations of itself is significant impact on scale inhibition and dispersion effect is one of the factors, on the inhibition of calcium carbonate and the influence of inhibiting calcium phosphate is different, the blocking calcium phosphate has the lowest concentration, only concentrations of pesticides than the lowest concentration, pharmacy is the role of inhibiting calcium phosphate. 2, whether the resistance of calcium carbonate or calcium phosphate resistance, are increased with the concentration of ferric ion, scale inhibition and dispersion effect decreased. Therefore, iron ions on water treatment agent of scale inhibition and dispersion effect obviously. With the increase of calcium hardness and basicity, scale inhibition and dispersion effect decreased. Therefore, calcium hardness and alkalinity have great influence on calcium carbonate and calcium phosphate. The effect of turbidity on the scale inhibition and dispersion was affected by different degree, but the effect of calcium phosphate was greater, and the effect of calcium phosphate decreased significantly with the increase of turbidity. 3, fungicides of different chemicals scale dispersed has a different effect, oxidation type sterilization agent for most drugs of inhibiting calcium phosphate have synergistic effect, non - the effect of oxidized germicide on different types of agents as agents and, synergism, antagonism.
All aspects of our lives away from the water, is not only our own need, is our production and living needs, and now the development of all aspects of make water have been unable to meet our use, so the water treatment chemicals into the us to the common material, generally around us water treatment chemicals there are several forms. A biocide Can effectively to dig for the reproduction of algae and slime growth, in different pH range has a good bactericidal killing capacity of algae, and have to disperse and penetration, can penetrate and remove slime stripping and attached algae.

Chinese is one of the more serious water shortage and pollution in the country. In 1993 the total water use in 1980 compared with an increase of 18.43%, reaching 525 billion 500 million m3, per capita water consumption is 450 m3. The water structure changed greatly, since 1980, the national agricultural irrigation and domestic water in rural areas (collectively rural water) was essentially flat, and industrial water and urban water supply will have a larger growth. In 1993, yellow, Huaihe, Haihe River Basins of per capita volume of water resources were 543, 500 and 351 m3, and water consumption per capita is 393, 301 and 347 m3. Foreign scholars believe that the per capita water resources in the amount of 1 000 m3 is the minimum standards for the realization of modernization, from the point of view of the current status and future development, to our country north of the yellow, Huaihe, Haihe river basins reached the per capita water resources in the amount of 1 000 M3 is extremely difficult, even to reach 500 m3 also need a lot of investment. From the Chinese situation, the current city of serious water shortage, has caused economic losses and serious social and environmental problems. The distribution of urban water shortage will be the focus in the North (North China, northeast, northwest) region and the eastern coastal cities gradually spread to the whole nation. It is important to save water, sewage treatment and the development of new water sources. Vigorously develop the role of water treatment chemicals important to save water and sewage management plays. Water treatment agent, which belongs to the category of fine chemical, compared to the commonly used chemicals. It has many characteristics of fine chemicals, such as production scale is generally small, therefore the plant less equipment investment, small production; many varieties of products, variety update quickly; high added value; technical service must not less; a variety of products, especially complex products, with strong specificity. A water treatment agent, foreign development status: At present, abroad has formed "the concept of industrial water treatment. According to the analysis of American industry expert Jean M.Kennay point of view, the industry can be divided into 3 parts, namely, product manufacturing, service and system construction. Products include water treatment equipment and chemicals manufacture, system construction refers to the construction of water treatment engineering, water treatment service refers to the technical service. Usually, chemical manufacturers also service providers. The industrial water treatment market sales of about $30 billion, equipment manufacturing and construction of the system of the industry accounted for about 73%. For the rest of the chemicals sales and technical services sales. Chemicals accounted for about 20%, estimates will not exceed $6 billion.
