Regenerable Foam Suppressor

A foam suppressor removes soap and other foaming agents from a stream of wastewater that is being treated electrolytically. This wastewater is a combination of laundry, hygiene, and urine wastewater. It is desirable to prevent foaming because foaming reduces, by about 15 percent, the efficiency of electrooxidation of waste chemical species. In the absence of foam, the electrochemical sensors used to monitor the treatment process also function more effectively and thus provide more-accurate control of the electrolytic process.
