Sewage treatment plant in Japan
Rural Community Sewerage
Previously, sludge was vacuumed out in this treatment plant without being dewatered; however, the cost for sludge treatment was huge. Thus, aiming at "zero-emission" of sludge, fermentation of the sludge was being considered.
Sewage Treatment Plant
In municipal wastewater treatment plant in snowy regions, snow-bound in winter, taking dewatered cake out regularly is sometimes difficult. Two problems were also presented in this municipal wastewater treatment plant, i.e., the difficulty of taking sludge out using carriers in winter, which had been anticipated from the planning stage of construction; and the need for reducing the number of sludge transportations by cutting the amount of sludge to be taken out, following prefectural policy.
