Digester roof repair

Belzona® 3111 (Flexible Membrane) Product repairs the connecting joints of concrete slabs on digester roofs found at wastewater plants to offer protection from atmospheric contamination. Digesters at wastewater treatment plants are instrumental in processing waste, which contains enormous energy value when converted to a usable form. When the roof suffers from severe erosion underneath due to years of neglect, the need to stop contamination from entering is paramount. In this type of environmental emergency, the flexible membrane repairs digester roofs to avoid methane gas from seeping into the atmosphere. Belzona Inc., Miami FL, 305-594-4994,

The unit is installed in wet wells, pump stations, scum pits, chemical tanks, digester level, and influent and effluent applications. It provides better accuracy, reliability, virtual immunity to process conditions and a lower total cost of ownership. STI Controls L.P., Downers Grove, IL, 630-969-4028 or

Cast iron slide gate

Cast iron slide gates are commonly used in sewage treatment, flood control and municipal applications. They are designed to control the flow of fluid through openings under a face or seating head as well as under back or unseating head. Offered in square, rectangular or round flanges, cast iron slide gates from Hydro Gate utilize vertical and horizontal ribs to provide sufficient strength to meet the required design heads. Hydro Gate, Denver, CO, 800-678-8228 or

Biogas collection cover

Gas collection floating covers collect methane gas from anaerobic process ponds later used to generate heat and/or electricity, or flared for carbon credits and/or odor control. A new prefabricated gas collection cover can be retrofitted to industrial, municipal and agricultural ponds. It uses a tough, fabric-supported, Enviro Liner 8000 for longevity and flexibility with integral stabilization weights to protect the cover from wind damage. In the field, gas collection piping is placed around the pond perimeter and the cover floated into place, with weight tubes not filled until the cover is anchored around the perimeter.
