Is an evaporator necessary to treat the Smart Sonic wastewater?
No. The Smart Sonic wastewater can be filtered in the same manner as other aqueous stencil cleaner wastewater. However, when using filtration, there is always an effluent left over for disposal. Most users prefer not to discharge an effluent to drain because of the associated liabilities. i.e. The EPA regulations state that if there is a hazardous contamination of the drain system (lead) and the source of the contamination cannot be identified, all generators of lead wastewater within a 50-mile radius will share in the cleanup of the contamination. When using evaporation, there is absolutely no liquid hazardous waste for disposal and nothing goes to drain. Evaporators cost less than their ion exchange or reverse osmosis filtration counterparts. Using evaporation is an advantage that Smart Sonic has because of the non-hazardous 440-R SMT Detergent. Other systems cannot evaporate their wastewater because the cleaning chemistry contains hazardous ingredients such as ethyl ether or VOCs.
