Wine distillery wastewater, commonly called vinasses, was treated by an anaerobic moving bed biofilm reactor (AMBBR) with 32.9 litre available volume. The reactor was filled with 66% cylindrical polyethylene supports with density 0.84 g cm(-3) as a biofilm carrier. The reactor was sequentially mixed by a submerged centrifugal pump fixed to the bottom, and each mixing time just lasted 1.25 minut...

The present study investigated the detection of severe acute respiratory syndrome–coronavirus 2 (SARS-CoV-2) genomes at each treatment stage 14 aerobic wastewater plants (WWTPs) serving major municipalities in two states Rajasthan and Uttarakhand Northern India. untreated, primary, secondary tertiary treated samples were collected over a time frame ranging from under-lockdown to post-lockdown c...

In the paper different nitrogen control strategies are proposed and tested on a simulation model of a combined preand post-denitrification plant. The plant configuration corresponds to the DomžaleKamnik wastewater treatment plant that will be upgraded for nitrogen removal using MBBR (moving bed biofilm reactor) technology. The aim of the study is to find an optimal control strategy in terms of ...

This article describes the use of biofilm reactors for the production of various chemicals by fermentation and wastewater treatment. Biofilm formation is a natural process where microbial cells attach to the support (adsorbent) or form flocs/aggregates (also called granules) without use of chemicals and form thick layers of cells known as "biofilms." As a result of biofilm formation, cell densi...

One of the key parameters in Fluidized Bed reactors is the control of biofilm thickness and configuration. The effect of upflow velocity on performance and biofilm characteristics of an Anaerobic Fluidized Bed Reactor was studied in treating Currant wastewater at various loading rates. The reactor used this study was made of a plexiglass column being 60 mm diameter, 140 cm height, and a volume ...
