The Watarase reservoir is the maximum flatland rservoir in Japan, and is one of the main water resources of metropolitan area. But at this reservoir, musty odorproblem arises frequently by the eutrophication, and it becomes a serious problem in water usage. Though the reed field purification method is being tried as a purification countermeasure, it is also necessary to examine the other method. Kenaf is an annual tropical plant originated from Africa. It is known that kenaf can grow also in hydroculture and that the good activated carbon can be producedfrom the wood-base trunk which can be utilized for the removal of the musty odor. As a result, kenaf may be able to contribute to the water purification in the Watarase reservoir.
Then, the author carried out the purification experimentby the kenaf hydroculture system using the reservoir water, and characteristics of the purification were examined.
Next they tried to produce activated carbon for water treatment from the core of kenaf. It was found that good activated carbon which removes color and odor (2-MIB) as well as other activated carbons on the market can be produced from kenaf core. Information on the activated carbon was reported.
