Reduction of cleaning frequency is addressed in terms of inhibition of fouling through proper squipment design and operation, maximization of equipment dedication, proper production scheduling, and avoidance of unnecessary cleaning. When cleaning has to be performed, the quantity and toxicity of resulting waste can be minimized by reducing clingage, amount of cleaning solution, choice of. less toxic cleaning solution, cleaning solution reuse, and other approaches.
