Agricultural Applications:

Animal slaughter and processing produces very strong organic waste from body fluids, such as blood, and gut contents. This wastewater is frequently contaminated by significant levels of antibiotics and growth hormones from the animals and by a variety of pesticides used to control external parasites. Insecticide residues in fleeces is a particular problem in treating waters generated in wool processing.

Processing food for sale produces wastes generated from cooking which are often rich in plant organic material and may also contain salt, flavourings, colouring material and acids or alkali. Very significant quantities of oil or fats may also be present.

• Run-off contained can be purified.  Waste from farms can be concentrated and re-used for fertilizers of for fuel.
• Animal processing can contaminate water where antibiotics, growth hormones, parasites etc. get into run off streams and into water supply.
• Insecticides, pesticides, residues in feces can get into processing and water.
• Vegetable washing can generate particulate matter, dissolved organics and may contain surfactants.
• Food products that are pre-cooked often bring undesired components into water used in porocesses.  Oils, fats, salts, flavoring, additives, coloring material, acids, alkali are a few.
