Construction of sewerage systems in the city of Yokohama has proceeded at a rapid pace ever since the first wastewater treatment plant went into operation in 1962. By 1984, all eleven of the planned wastewater treatment plants were in operation. By March 1989, the sewerage service rate had reached 80 percent, representing over 2.56 million of the city's residents. Naturally, the expansion of the sewerage system was reflected in a commensurate increase in the quantity of sludge for treatment and disposal. Recognizing the critical importance of keeping abreast of this increase, the city has promoted the development of technology for more efficient treatment and disposal of sludge throughout the intervening years. In recent years, the city has also seen extensive urbanization and mounting concern among its citizenry for conserving the environment. In response, it was decided to shift from the former decentralized method of sludge treatment (i.e., treatment of sludge at the plant generating it) to a method of centralized treatment at two sludge treatment centers, each built within a different wastewater treatment plant located in the waterfront area. Yokohama was the first city in Japan to adopt this form of centralized sludge treatment. The construction of the centralized sludge treatment facilities made extensive use of results from a program of technological development. The centers feature the first egg-shaped digestion tanks, a high-concentration mode of digestion made possible by the use of centrifugal thickeners, power generator fueled with digestion gas, effective use of the waste heat from these generators, and the saving of fuel by the use of incinerators equipped with dryers. The record for the first year of full-scale operation clearly demonstrated the merits of centralized treatment. The quantity of digestion gas generated at the center was double that of the quantity generated under the former method for an equivalent quantity of sludge. Power generation fueled by digestion gas supplied 64 percent of the center's own power needs. While operating at only one-fifth of the planned sludge capacity, the center boasted a savings of about 200 million yen for the year, and the treatment costs were less than half of the treatment cost of the same quantity utilizing the former method. This report presents an account of the operational record for the first year of this center (the Hokubu Sludge Treatment Center) and the system of effective energy use that took place in it.

This study summarizes the findings and lessons learned from the start up and operation of a large wastewater treatment plant in warm climate under modified conditions. The treatment works comprise of a newly constructed sewage treatment plant located in the city of Dubai, U.A.E with an ultimate capacity of 300 Ml/d. The plant can be reviewed in three major parts; (i) liquid stream, (ii) sludge stream and (iii) odor control stream all having the latest state of the art technology and related equipments. The challenge in starting up the plant was related to the fact that only 20% of the flow was available in the form of hauled sewage to be hauled from septic tanks located in various parts of the city and also from the nearby industry which was uncontrollable. Furthermore, some parts of the plant were not ready to be commissioned on the day of the planned startup not to mention that effluent irrigation main was not complete to receive the treated sewage effluent (TSE) from the plant. A comprehensive commissioning plan was implemented and followed during the startup which was tailored according to the actual conditions. The plant commissioning was conducted in a phased sequence to cater for the expected and unexpected changes related to the inlet conditions. Commissioning and operation of the plant was carried for over 18 months with success considering the challenging and difficult conditions.
