Sumo© from Dynamita is the newest and most versatile dynamic simulation package on the market. After the influent measurements and plant configuration are entered, Sumo knows what kind of effluent quality will result, even daily peaks or during storms, and the user can try many operational or control scenarios in a short time. Sumo has advanced high rate, sidestream (anammox) and sulfur modelling (ORP, EPS, colloids). Sumo can handle treatment plants of unlimited complexity, BOD, nitrogen and phosphorus removal, digestion, sidestream treatment, IFAS and MBBR, SBRs, trickling filters, granular sludge, membrane bioreactors, primary and final settling, thickeners, centrifuges and all process units typically used in municipal and industrial treatment plants. It comes with many real-life examples and a detailed manual to help the introduction of advanced modelling for new users. Sumo is already used worldwide in Europe, North America, Australia and Asia by design engineers, municipalities and plant personnel, as well as in universities. Its main advantages are its open process source code, very fast simulation times, extensive model set and affordable pricing. The international team behind Sumo is well known for its outstanding support which is included in the license.
