AMCON has been tackling challenges
and making innovations to offer solutions to various problems customers face.

AMCON INC. was founded as Environmental Facility Center in Meguro, Tokyo in 1974. The center offered maintenance services for septic tanks, community wastewater treatment plants and other similar treatment facilities.
While operating services, we acquired know-how about machine repair and wastewater treatment. Five years after the establishment, we launched measurement certification business that had been outsourced until then.
Three years later, we developed and launched a belt-thickener used for sludge treatment at wastewater treatment facilities. We also launched a 24-hour remote monitoring service for water and sewage systems of residential and commercial buildings.

In 1987, the company changed its name to AMCON INC. Since then, we have put effort into research and development of sludge treatment systems, aiming at establishing ourselves as a machine manufacturer.
In 1991, we developed the VOLUTE™ Dewatering Press, a system with an innovative structure. This product brought a new perspective to the sludge treatment industry.
AMCON INC. will continue our efforts to tackle challenges and make innovations. “Solving our customers’ problems” is our watchword.
