Your substrate may react to specific cleaners. Waste generation and disposal Recyclability of the cleaning solution is an important consideration for both economic and environmental reasons. Recycling may reduce the need for disposal of hazardous wastes. Perform a cost analysis Compare the total cost of current and alternative practices. Equipment selection New equipment may improve cleaning capabilities, including equipment designed for specific parts, spraying mechanisms, and ultrasonics.
Emission controls reduce solvent releases, conserve expensive solvents and limit worker exposure.
The following are some equipment modifications and purchases which can reduce emissions during the time you are switching from chlorinated solvents Equipment Modifications Raise the freeboard to one times the chamber width. The effectiveness of chillers depends on temperature and type of solvents, temperature of chillers, placement, effectiveness of water separation and other factors. Reduce dragout by using mechanically assisted parts handling. Solvent dragout can be minimized by reducing the vertical conveyor speed to 10 feet per minute or less. And automation provides adequate dwell time.
