  • Heat recovery from wastewater

    Heat recovery from gray water is particularly important in water-intensive industries such as pulp and paper plants, dairies and breweries. Rather than flushing used water down the drain, consider whether a heat exchanging system can help you put that energy to work in your process again. Most plant operators arc aware of the need to save money and reduce the environmental impact of their plant ...

  • 24kW Ground Source Heat Pump In Essex - Case Study

    The space heating and hot water for this property was previously done by an oil boiler. The client was considering a ground source heat pump in order to lower running costs and benefit from tariff payments under the Renewable Heat Incentive (RHI). Better Planet carried out a room by room heat loss calculation. This is required in order to size the heat pump ...


  • Class a biosolids production at eastern municipal water district using heat pasteurization

    Since 1998, the Eastern Municipal Water District (District) has developed and successfully operated a heat pasteurization facility to treat extended aeration waste activated sludge (WAS) from the Perris Valley Regional Water Reclamation Facility (PVRWRF). The treatment train uses hot water to sludge spiral heat exchangers and a patented continuous-feed, complete mix pasteurization vessel (heated ...


  • Efficient Operation of Lighting, Hot Water and Air Conditioning: Hotel Inter Continental Sydney

    To improve its environmental performance and save nearly $300,000 per year, the Hotel Inter Continental Sydney changed some practices that seemed insignificant in themselves but which collectively, wasted massive resources. The changes cost around $275,000 and no adverse affect on guest amenity. They included lowering the power of lights that were too bright, lowering the temperature of ...

  • The design of static mixer heat transfer equipment for adhesives, sealants, resins and polymers.

    The fluids handled within the adhesives and sealant industries are amongst the most difficult to handle of any in the main process industries globally. The characteristics which make them particularly difficult to handle include: High viscosities (typically 1-2000 Pa.s, or 1000 to 2 million cP). Often non-Newtonian (viscosity is not constant and varies with shear rate). Some ...
