Anyone who has operated an anaerobic digester has had to contend with digester foaming issues. As an operator of several digesters with varying feedstocks, quasar has come face to face with foaming incidents over the last several years. quasar laboratories have worked with the interaction of biomass feedstocks and have determined that a number of foaming incidents can be prevented by fully understanding these interactions and implementing engineered solutions. Sometimes, simple changes in feeding schedules is all that is required.
If you are experiencing foaming problems in your digester, let quasar assist in troubleshooting to help resolve the problem.
