What is biological waste water treatment?
Biological waste water treatment is the primary method of preparing food-processing waste water flows for return to the environment. Increasing waste water loads on existing plants and more stringent government discharge requirements have put considerable pressure on the food-processing industry to refine and understand better the design and management of biological waste water treatment processes. Though activated sludge and other biological treatment processes are still frequently operated by general guidelines and ‘rules of thumb,’ facility design and operation must be guided by consideration of both the physical and biological aspects of waste water treatment. Various modifications and combinations of aerobic and anaerobic biological treatment processes are commonly used in the food-processing industry.

What is water cooling?
Water cooling is a method of heat removal from components of machinery and industrial equipment. Water may be a more efficient heat transfer fluid where air cooling is ineffective. In most occupied climates water offers the thermal conductivity advantages of a liquid with unusually high specific heat capacity and the option that of evaporative cooling. Low cost often allows rejection as waste after a single use, but recycling coolant loops may be pressurized to eliminate evaporative loss and offer greater portability and improved cleanliness. Unpressurized recycling coolant loops using evaporative cooling require a blowdown waste stream to remove impurities concentrated by evaporation. Disadvantages of water cooling systems include accelerated corrosion and maintenance requirements to prevent heat transfer reductions from biofouling or scale formation. Chemical additives to reduce these disadvantages may introduce toxicity to wastewater. Water cooling is commonly used for cooling automobile internal combustion engines and large industrial facilities such as nuclear and steam electric power plants, hydroelectric generators, petroleum refineries and chemical plants .
