Sasakura Engineering Co., Ltd.
Sewage Treatment Plant "Super Trident"
Long committed to the conservation of the beauty of our oceans while developing ever superior technology for the prevention of marine pollution, Sasakura Engineering Co., Ltd. manufactures Super Trident sewage treatment plants in Japan under a technical license arrangement with Hamworthy Marine Ltd. of the U.K.
Sasakura has already delivered more than 5,000 units of Super Trident, which is a sewage treatment plant that incorporates a locally developed activated sludge process that features long-term aeration.

2. Complete treatment by long-term aeration: The aeration system, which ensures 24 hours (twice as long as usual) of contact between sewage and activated sludge, results in high resistance to load fluctuations, and the quantity of discharged sludge is extremely small.
3. Maintenance ease realized by user-oriented technology: Fillers are not used within the unit, so the plant is tree from blockage and easy to clean.
4.Fully automatic control system ensuring operating ease: The plant is controlled automatically, and therefore does not require any manual monitoring or operation.
