Pollution Assessment in Terms of Organic Loading in Pathum Thani Province
Abstract
The study aims to assess the organic matter loading of wastewater sources in 2020 and 2040 of Pathum Thani Province. The organic matter loading is estimated in term of Biochemical Oxygen Demand (BOD) from three different sources: community, industry, and agriculture (livestock, freshwater aquaculture, and farmland). The results found that in the year 2020, the sources of industrial wastewater have the highest organic matter loading, followed by community and agriculture wastewater sources. The values are 24,113.19, 23,982.87 and 3,481.15 kg/day for the three sources above, respectively. However, the load of organic matter from community source is the most, followed by industrial and agricultural sources in the year 2040. These values will increase to 29,140.64, 22,261.41 and 4,718.65 kg/day, respectively. The results of this study in Muang Pathum Thani district are the highest load of organic matter. The wastewater treatment system should be improved to be effective to reduce in both quantity and concentration of organic matter from all sources. The results obtained from this study could be useful in planning the wastewater treatment plant capacities, guidelines, and measures to reduce future water pollution of Pathum Thani Province.
