Development of in-house lattice-Boltzmann simulator of bioreactors for wastewater treatment: basic concepts and initial results
While computational modelling has increasingly supported wastewater bioreactor engineering, novel numerical techniques have been developed such as the lattice-Boltzmann method (LBM). With vinasse treatment as case study, this work is a first step towards a comprehensive LBM simulator of a continuous-flow anaerobic packed-bed reactor. Extensions from typical models comprise one-dimensional ...

Calibration and verification of models of organic carbon removal kinetics in Aerated Submerged Fixed-Bed Biofilm Reactors (ASFBBR): a case study of wastewater from an oil-refinery
The article presents a case-study on the calibration and verification of mathematical models of organic carbon removal kinetics in biofilm. The chosen Harremöes and Wanner & Reichert models were calibrated with a set of model parameters obtained both during dedicated studies conducted at pilot- and lab-scales for petrochemical wastewater conditions and from the literature. Next, the models were ...

Mathematical modelling of biofilms and biofilm reactors for engineering design
Mathematical models are critical to modern environmental biotechnology—both in research and in the engineering practice. Wastewater treatment plant (WWTP) simulators are used by consulting engineers and WWTP operators when planning, designing, optimizing, and evaluating the unit processes that comprise municipal and industrial WWTPs. Many WWTP simulators have been expanded to include a submerged ...

Goodbye Grease! Aqua Mundus Helps Catering & Commercial Kitchens Manage Fat, Oil & Grease Wastewater
While fat, oil and grease can cause major blockages to piping and sewers, Aqua Mundus is helping thousands of commercial and catering kitchens implement a solid grease management infrastructure and flush away these nasty problems for good. While pouring fat, oil and grease (FOG) down a commercial sink may seem like a good idea, their solid properties can cause dangerous build-up and even block ...

Wastewater Is An Asset | It contains nutrients, energy and precious metals
People think as little as possible about the wastewater that is produced daily from their showers, bathtubs, sinks, dishwashers and toilets. But with the right techniques, it can become a valuable resource. On average, every Americans uses about 60 gallons of water per day for purposes that include flushing toilets, showering and doing laundry. This figure can easily double if outdoor uses, ...

Mississippi - Community case study
The devastation and destruction caused by Hurricane Katrina in 2005 has forever impacted the Gulf Coast. The devastation and subsequent rebuilding has led to a shift in ideology from just simply "building back" but into how can we "build better" to reduce the impact of a similar storm in the future. Wastewater infrastructure design and construction have been fundamentally changed thanks to the ...
