 This Week's Photo                   I

This week's photo is of a WWTP at Tembec's facility in Temiscaming, Quebec.  Wastewater from pulp production is treated in two BioPaq IC reactors where COD is converted into 50.000 m3/d of methane gas, before being treated in the activated sludge plant.  The methane gas is desulpurized in a ThioPaq scrubber and used for pulp drying.

MICROCAT Products for FOG and Odor Control
MICROCAT products are formulated to eliminate the problem associated with fats, oil and grease (FOG) accumulations in drains, grease traps/interceptors and lift stations. MICROCAT products accelerate the biodegradation of FOG under aerobic to anoxic conditions. The microbes complete the conversion of organic materials to carbon dioxide and water, eliminating the FOG that can cause blockages and odor problems. Application of MICROCAT products in the collection system will reduce organic load on the downstream treatment plant. These products also contain microbes that oxidize hydrogen sulfide (and other reduced sulfur compounds) even at low dissolved oxygen concentrations. Web: http://www.bioscienceinc.com/
