Technology data

Name of technology	Activated Sludge Method JRK-SYSTEM
Field of the technology	Major category: Prevention and destruction of pollution	Sub-category: Industrial waste water, Sewage, Land water
Conceivable applications	Purification of a river or a lake Treatment of industrial organic wastewater Treatment of community plant
Performance	BOD removal is more than 90% JRK Purification System is a new technology which does not need a sludge treatment. This system performs with clumped crushed rocks called JRK. Particle size of a clot, JRK, is about 100 mm. The clots consist of several 20- 30 mm large crushed rocks. The rocks are bonded with resin.
Technical maturity	Purification of a river or a lake： About 30 plants in Japan Treatment of industrial organic wastewater： About 10 plants in Japan Treatment of community plant： Under construction Oversea market： (South Korea) One plant
Competitive advantage	1) Comparison of construction costs Conventional activated sludge method/JRK=1/0.5 2) Comparison of operation cost Conventional activated sludge method/JRK=1/0.1 Waste sludge processing is not required. Operation management is easy.
Conceivable risk	In the conventional activated sludge method, sludge adsorbs and removes the phosphate ion which is dissolving. A phosphate ion is not removed by the JRK-SYSTEM which sludge does not generate.
Information on patent related to this technology	Patent NO.JP-3177432 Overseas application country: JAPAN, USA, CANADA, SOUTH COREA, CHINA, EU(6 country), R.O.C
