Australian canned fruit and fruit drinks company Golden Circle (Brisbane) is planning to install a larger boiler to take better advantage of biogas produced from the anaerobic processing of wastewater at its food processing plant in Northgate, Queensland.

The plant already burns about 30% of the biogas it produces, and with the new boiler will utilize about 90% of the generated biogas, said Jason Carter, environmental manager at Northgate, in a press release.

The existing boiler offsets about 5% of the plant’s coal use, and the new boiler, when completed and running before the end of this year, will offset about 15% of the coal use, Carter said in the release.

The Northgate plant began to use biogas in the late 1990s to contribute to the steam needs of the operation. The biogas presently feeds a 3.5-MW boiler that produces about 5 Mg of steam per hour, used for cooking foods, pasteurization, and sterilization.

Golden Circle’s wastewater plant, which relies on high-efficiency anaerobic technology from CST Wastewater Solutions (New South Wales, Australia) and Global Water Engineering (Austin, Texas), already has saved Golden Circle more than $2 million a year in effluent disposal since the plant was upgraded to cope with increasing production volumes.

 

Kruger Inc. (Cary, N.C.), a Veolia Water Solutions & Technologies company, in June announced that it had completed startup and commissioning of a Hydrotech Discfilter system for the City of Galt, Calif. The project goal was to improve effluent water quality from the facility prior to discharge into Laguna Creek.

The system includes three HSF2210-1F Discfilter units and is designed to filter up to 22,700 m3/d (6 mgd) to produce effluent with average turbidity less than 2 nephelometric turbidity units in accordance with California Title 22 requirements for the use of recycled wastewater. The system was commissioned for use in November 2010.

 

McCarthy Building Cos. Inc. (St. Louis) this spring broke ground for the water and wastewater master plan for the Upper Fruitland Casino, an 8300-m2 (89,000-ft2) gaming facility under construction in San Juan County, N.M. The $3.7 million comprehensive water project will include the water and wastewater master plan and associated facilities to specifically serve the Upper Fruitland Casino, and accompanying hotel and restaurant.

The company plans to install 1200 lineal m (4000 lineal ft) of water and wastewater pipe, a pump station with a storage tank for the casino’s potable water supply, a wastewater treatment plant, and facilities to house the control room and electrical and pumping equipment necessary for the project.

The casino, which will hold 750 slot machines, is slated to be completed in December.
