- Supply chain operation: Planning, logistics, regulatory compliance, invoicing, commercial maintenance of contracts and competitive intelligence.
Innovations to serve your digestion facility
SEDE develops fast and reliable measuring tools. This allows us to offer complementary assistance in monitoring biological performance particularly adapted to digesters.
Based on measurement tools based on near infrared spectroscopy technology, SEDE will be able to provide an instantaneous response on the parameters of interest in digestion, associated with the biological performance of a process (dry matter and organic matter content, volatile fatty acid, ammonium and alkalinity concentrations).
