Research enterprise name
Next generation core environmental technology development project
Research title
Study on disk-type thickener development and applications using sludge separation/flocculant characteristics
Period
June 1, 2003 -May 31, 2006
Host
ARK Co., Ltd.
Association
Catholic University
Summary
In order to solve problems such as reduction of water content percentage due to wastewater treatment plant development and strong concentrations in wastewater inflow, and phosphorus discharge in the existing thickening and dehydration process, in the disk-type thickener, using the CMT process, the concentrated sludge is loaded into the digester and dehydrator in equal parts. The phosphorus re-discharge amount is less than 5%, and the water content percentage in the dehydrated cake is less than 7% when applied to the existing belt-press dehydrator; the treated amount is over 2 times higher than with existing equipment. This mobile disk-type thickener can replace a gravity dehydrator and be used in a small ranged treatment plant.
 
Research enterprise name
Next generation core environmental technology development project
Research title
Digester improvement technology development for wastewater sludge reduction and bio-gas production
Period
April 1, 2007 -March 31, 2010
Host
ARK Co., Ltd.
Association
Korea Institute of Science and Technology

Summary


The digestion improvement technology increases the inflow sludge concentration rate and digestion mixture efficiency using an anaerobic digester process, which can be applied by retrofitting it to existing digesters, corresponding with sludge form changes due to advanced process introduction.
 
Research enterprise name
generation core environmental technology development project
Research title
Economical and anticipated sludge dehydration system development for small and medium sewage treatment plants
Period
December 1, 2008 ~ December 31, 2010

Association
Beijing University
Summary
In China, as industry quickly develops and modernization progresses rapidly, a lot of wastewater treatment plants are being built because demand is increasing. The amount of treated sludge is consequentially also rapidly increasing. However, due to difficulty in the process and site selection, high maintenance expenses, and low technology, the sludge is not properly treated. ARK Co., Ltd. understands the characteristics of the sludge treated in Chinese wastewater treatment plants and develops mid-range (100,000/day) sludge reduction equipment, combined with disk-type thickeners and screw press dehydrator and is planning wide distribution in China.
