Montreal Canada- DDI Heat Exchanger Inc. announced that it has received a Letter of Intent for the Owen Sound wastewater Treatment Plant Upgrade from J.L. Richards (in Cooperation with Conestoga-Rovers & Associates (CRA) ) to purchase a total of Three (3) DDI Rectangular Technology Heat Exchangers consisting of :
· One (1) Direct-Sludge-to-Sludge Heat Recovery exchanger
· One (1) Mesophilic Heat Exchanger
· One (1) Thermophilic Heat Exchanger
Company officials are expecting the required deliveries to be within one year.
Thanks to the local Ontario Representative, Directrik Inc, who promoted the merits of the DDI Direct-Sludge-to-Sludge Heat Recovery Exchanger and the Water-to-Water heat exchangers.
DDI System has been tested for more than 9 years of continued use without any plugging issues.
DDI has the following main advantages: large heat transfer surface, small foot print, more turbulence flow, gaps of 3 inches minimum to limit the sludge blockage, full access to internals via ECPS Cleaning ports, optimum height for fast flow, realistic viscosities calculations, thick layers against abrasion (0.25” min), a backup that is also able to use the sludge-to-sludge heat exchangers for the water-to-sludge process and very low maintenance.
