Abstract：In order to achieve a good performance of a reverse osmosis (RO) system for wastewater reclamation, many kinds of chemical reagents are used in microfiltration(MF)/ultrafiltration (UF)-RO process. The chemical reagents used for a MF-RO process in a wastewater reclamation plant in Beijing were evaluated Disinfectant, antiscalant, reductant, non-oxidizing biocides, neutralizer and cleaning reagents were used in this plant. The production amount of reclaimed water of the plant was about 7000m3/d. The dosage of total reagents was 3347.3kg per week and the average dosage of reagents was 68.32g per ton permeat. The total cost of the reagents was about 19,120 RMB per week and the cost of reagents was 0.39 RMB per ton permeat. Cost of antiscalant accounted for 47.44% of the total cost of reagents.
