food waste separation Applications

  • Oil water separation for the food industry

    Packaged-food producers frequently use and then must discard large batches of cooking oil used in their process. Usually they drain most of the oil directly from equipment, but they must remove residual oil by regularly washing fryers, ovens, conveyors, and other machinery. 

    The oil mixes with the wash water and becomes part of the plants wastewater stream. Having oil in wastewater complicates the wastewater-treatment process by making it more expensive, more time-consuming, and less effective. Additionally. as with other manufacturers, packaged-food producers want to reduce waste and decrease the environmental impact of operations. That is why removing used oil and solids from wastewater before it is discharged is a priority.

    Separation solutions for food rendering industry

    Rendering is a process that converts waste animal tissue into stable, value-added materials. Edible rendering processes are basically meat processing operations and produce lard or edible tallow for use in food products. Edible rendering is generally carried out in a continuous process at low temperature (less than the boiling point of water). The process usually consists of finely chopping the edible fat materials (generally fat trimmings from meat cuts), heating them with or without added steam, and then carrying out two or more stages of centrifugal separation. The first stage separates the liquid water and fat mixture from the solids. The second stage further separates the fat from the water.

  • Membrane filtration systems for milk

    Since the introduction of membrane processing to the dairy industry in the late 1960`s, separation of dairy fluids using semi-permeable membranes has been used to clarify, concentrate and fractionate a variety of dairy products. The time honored and tested applications involving whey processing, the by-product of cheese making, have introduced a plethora of refined proteins and commercial uses for a once wasted by-product. The membrane applications for fluid milk have been understood for as long as the whey applications but have been underutilized in commercial applications.

  • Membrane filtration systems for whey

    Before the innovation of membrane processing was introduced to the dairy industry, in the late 1960`s, whey was truly a waste product of cheese making. Three important events have driven whey towards further processing; increased cost of dumping whey into the environment; new technologies to separate the proteins in whey and scientific research that has uncovered the wide range of nutritional and biological properties of whey that have ultimately added value to a once wasted product.

  • Activated Carbon Filtration for the Water Filtration Industry

    General Carbon carries a complete line of activated carbon made from coal, coconut shell and wood for most liquid phase applications.  These include acid washed activated carbon for drinking water and food grade applications as well as products suitable for waste water remediation, decolorization applications, chemical and pharmaceutical purification. Additionally, our specialty medias are best for the treatment of non-emulsified oils and heavy metals. Our stock of activated carbon for liquid phase applications are all NSF certified, meaning that they are approved for treatment of food grade applications.

  • Wastewater Treatment for Municipalities

    PBS Velká Bíteš develops and manufactures machines for the separation of solid and suspended particles from liquids. The so-called "Decanter Centrifuges" can be used for a wide range of applications: from separation of municipal and industrial sludge in waste water treatment plants, through food and chemical industries up to agriculture. In the area of separation, we offer not only the decanter centrifuges themselves, but also the related services, including servicing of third-party equipment.
