Ultra-high processing technology for aquatic system 　　　　　　　　　　　　　　　　　　　　Waterkeeper 　Pruification Technology by Microbe Activation Improvement of aquatic sphere by a novel biocatalyst, Waterkeeper, through decomposition of both organic compounds and organic sedimentary sludge 　　　　(Recovery and protection of aquatic environment, Energy saving by 30%to50%) 　　　　　　　　WK can easily be diffused over the whole polluted water area. WK liquid 　　Applicability toward purification of aquatic area 　　①Fresh water area; river ,lake, pond, etc. 　　②Sea water area. 　　③Sewage treatment work. 　　④Factory effluents. 　　Item 　　1:Decomposition of organic sludge. 　　2:Increase in transparency of aquatic area. 　　3:Recovery of ecosystem. 　　4:Reduction or elimination of algae. 　　5:Energy saving. 　　6:Water quality maintenance. 　　7:Enormous reducction of running cost. Scientific consideration by Professor Hidehiro Kumazawa 　Before　the addition of WK 　　　　　　　　　　　Improvement stage Ⅰ (Phase 1) 　Improvement stage Ⅱ (Phase 2) 　　　　　　　　Improvement stage Ⅲ (Phase 3)　 Purification of rivers (Transparency,Organic slude decomposition) 　　 Whole of WK polyethlene tank WK dropping equipment and how to connect pipes Change in transparency Doi river Transparency 10cm After 9 months (Sea water) Transparency exceeding 100cm Organic sludge decomposition Urakawa river(sea water) 　　After 7 months, sludge decomposition up to 50cm Shichibu rever(fresh water) After 5 months transparency recovered and sludge decomposition continued Sewage Treatment Works 　① After the addition of Waterkeeper for about 3 months, the excess organic sludge amounts to zero. 　② Enormous reduction of running cost (coagulant cost zero, Sludge disposal cost zero). 　③ Energy saving (30%～50% reduction of electricity, transportation, etc). Waterkeeper dropping equipment 　　Locastion 　　Arao city purification center, Kumamoto Pref, Japan 　　5th Sewage treatment works, Kumming city, China 　　Yeoncheon Province, Gyaeonggi-do, Korea Algae or elimination After 4 months After 2 months algae reduction 　　　　　　　　　　　　　　Comparison of merit and demerit of organic sludge discharge 　　　　　Methods of sludge dioposal from river, sea, sewage treatment works, industrial effluents, etc. Solid-Liquid Separation 　Merit due to the decomposition by Waterkeeper addition 1 　Disposal as industrial wastes 　No need (extension of disposal site life) 2 　Incineration (CO2,NOx discharge) 　No need (bad for the health prevention of soil pollution, 　suppression of global warming) 3 　Transportation ( 　〃　　　　〃　　　) 　No need (reduction of cost) 4 　Sea disposal (Forbidden in 2008) 　NO need (prevention of sea pollution) 5 　Composting (transportation, cost much) 　No need (reduction of cost) 　　　　　　contact: 　Minaki Advance Co., LTD 　　　　　　　　　　　　　　　Yorio Tanaka 　　　　　　　　　　　　E-mail:tanaka-wk@minaki.co.jp 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　To Top 　｜home｜technology｜rivers｜sewage｜effluents｜energy saving ｜ 　Minaki Advance Inc.
