Cavia equipment has been specially developed for increasing biogas production and reducing sludge residues in wastewater sludge digestion processes. This can be used to meet the energy needs of the wastewater treatment plant, and it can also be sold as necessary. The process also successfully reduces the final quantity of sludge produced, reducing the need for chemicals and for transportation and final disposal of sludge. This environmentally friendly equipment can be readily incorporated into newly designed and existing sludge treatment processes.
Junior Chamber International Finland organizes the Productive Idea competition for the 33rd time this year. This year other partners in the competition are Ministry of Employment and the Economy, Finnish Industry Investment Ltd, Federation of Finnish Enterprises, The Central Chamber of Commerce of Finland, The Association for Finnish Work, IF, Nordea, Sitefactory and Tamro Finland.

Spanish company Cadaqua S.A. invests in in large scale product development and commercialization. Highlights of this setup include the revolutionary CAVIA Ultrasonic Disintegration system that improves the efficiency of wastewater sludge digestion, enabling an increase of up to 40 percent in biogas output and a reduction of about 25 percent in final solid sludge.
Dewaco recently concluded an agreement with Cadaqua S.A. to supply the first CAVIA system to the Chorzow wastewater treatment plant at Klimzowiec in southern Poland. The biogas generated by processes at the plant is used for heating. The modernization of the plant will increase the need for biogas, and CAVIA equipment will be incorporated into the process in order to meet this need. The Dewaco solution included two CAVIA appliances, each containing two ultrasonic reactors, together with pumps, process equipment and a control system. The process will be monitored on site and can also be regulated remotely from Dewaco. The equipment was installed at the plant by the end of October 2010 and commissioned immediately.
Dewaco’s CAVIA system has been specially developed to increase biogas production and reduce sludge residues in wastewater sludge digestion processes. An Ultrasonic Disintegration reactor based on ultrasound technology enables the production of more biogas from sludge. This can be used to meet the energy needs of the wastewater treatment plant, and it can also be sold if necessary. The process also successfully reduces the final residual of sludge produced, reducing the need for chemicals and for transportation during the final disposal of sludge. The Technical Research Centre of Finland – VTT has analysed and verified the increased biogas production and sludge reductions achieved by CAVIA equipment. This environmentally friendly equipment can be readily incorporated into newly designed and existing sludge treatment processes.
