Abstract：

Scale is one of usual problems in reverse osmosis and circulating water systems. By comparing components of scales on reverse osmosis and in conderser tube, the change of pH, CO2 and carbonate ions, carbohydrate equilibrium have been compared and analyzed in reverse osmosis and circulating water systems.In the end, the selection of anti-scalants been suggested based on scaling characteristics.
