Removal of Bottom Sediments in Osaka Port by the Pneuma Pump Dredge 'Shunkai',

Abstract

Osaka Port has been suffering from mud sediments polluted with organic substances on the bottom of rivers due to wastewater from factories and city sewage. The Authority of Osaka City, having noticed the excellent performance of the Pneuma pump system, undertook the first mud dredging experiment in Japan with that system (which was introduced in Dec. 1971). Through this experimental dredging, the suitability of the Pneuma pump system to the dredging of polluted mud was well proved. A dredging squadron with hopper barges that had undergone the necessary modifications was organized. The squadron has engaged in dredging operations of polluted mud since Nov. 74 to the present.
