'the action of making the best or most effective use of a situation or resource'
Before a clean can be optimised a clear objective must be set. This enables the results of any changes to be evaluated against that objective. Objectives typically set include:
Improvement in efficacy of clean.
Reduction in the cost of cleaning. This will include:
Labour and supervision cost.
Detergent and disinfectant cost.
Energy cost.
Water and effluent cost.
Maintenance cost.
Reduction in water use due to constraints on supply or disposal.
Reduction in cleaning time allowing a greater process plant up-time.
Increase in the recovery of product from the process plant. This means less product is flushed to drain.
Effective recovery of product includes techniques such as pigging or water rinse with recovery to process / waste stream.
