In addition, there were previous attempts to solve water pollution in Khlong Saen Saeb. One of them is the Government’s plan to utilize microorganisms for water treatment. Government put the microorganisms with molasses, its foods, into the canal. They expected the microorganisms to fully grow and generate oxygen in the water. Unfortunately, the said microorganisms grow so slow that the molasses have fermented, resulting in increasing in Biochemical Oxygen Demand (BOD), so to speak, more water pollution. Besides, at that time, households, of which mostly had little income, had to buy the microorganisms themselves. So, this project was fold in short period of time.
