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 ...

Meltwater flow through a rapidly deglaciating glacier and foreland catchment system: Virkisjökull, SE Iceland

Virkisjökull is a rapidly retreating glacier in south-east Iceland. A proglacial lake has formed in the last ten years underlain by buried ice. In this study we estimate water velocities through ...

Non-PFAS Highlights from REMTEC 2019

I had the pleasure of attending REMTEC 2019 in Denver last week. As always it was great to catch up with colleagues and hear about new developments in our industry. While much of the discussion centered around the looming challenges of PFAS ...

Flow Control Valve

The valve controls downstream flow to a pre-set and constant value in order to limit water consumptions and preserve pipeline fill rate or to set a maximum demand value. The valve is controlled by a differential hydraulic pilot that senses the pressure fall generated by water flow into a calibrated orifice.
