MBBR Helps Seafood manufacturer meet regulatory requirements

Abstract Seafood processor in Manta Ecuador has a high strength wastewater with TSS as high as 20,000 mg/l, FOG 700 mg/l, COD of 13,000 mg/l and BOD of 6,000 mg/l. Wastewater is discharged into Pacific Ocean across the street from the factory. Current treatment plant produces effluent with TSS of 150 mg/l, FOG of 80 mg/l, COD of 800 mg/l and BOD of 400 mg/l on average. New laws require that ...

$Organic removal activity in biofilm and suspended biomass fractions of MBBR systems$

Organic removal activity in biofilm and suspended biomass fractions of MBBR systems

The moving bed biofilm reactor (MBBR) wastewater treatment process is usually designed based on the assumption that all activity in the process occurs in the biofilm on the MBBR carriers, although there is always some active biomass in the bulk liquid due to biofilm sloughing and, sometimes, free-growing bacteria. In this study the removal of organic matter is evaluated in laboratory-scale MBBR ...

Energy, cost and design aspects of coarse- and fine-bubble aeration systems in the MBBR IFAS process

With the MBBR IFAS (moving bed biofilm reactor integrated fixed-film activated sludge) process, the biomass required for biological wastewater treatment is either suspended or fixed on free-moving plastic carriers in the reactor. Coarse- or fine-bubble aeration systems are used in the MBBR IFAS process. In this study, the oxygen transfer efficiency (OTE) of a coarse-bubble aeration system was ...

MBBR system performance improvement for petroleum hydrocarbon removal using modified media with activated carbon

Moving bed biofilm reactor (MBBR) system has a successful operation in the treatment of different types of wastewater. Since the media, i.e. the place of growth and formation of biofilm, play the main role in the treatment in this system, MBBR systems were operated in the present research with modified Bee-cell media. Activated carbon granules of almond or walnut shells were placed in media ...

Quantification of kinetic parameters for heterotrophic bacteria via respirometry in a hybrid reactor

Over the last decade new technologies are emerging even more for wastewater treatment. Among the new technologies, a recent possible solution regards Moving Bed Biofilm Reactors (MBBRs) that represent an effective alternative to conventional processes. More specifically such systems consist in the introduction of plastic elements inside the aerobic reactor as carrier material for the growth of ...

Case study: Pulp & paper industry

OverviewThe paper mill at Valdivia produces card board from chemical and mechanical pulp. With the installation of an additional paper machine, the wastewater flow increased from 4,000 m3/d to 8,500 m3/d and therefore an extension of the existing wastewater treatment plant was required. RequirementSo far, the existing effluent treatment plant consisted of a primary ...

Nitrogen and carbon removal efficiency of a polyvinyl alcohol gel based moving bed biofilm reactor system

In this study, the effectiveness of polyvinyl alcohol (PVA) gel beads in treating domestic wastewater was investigated: a moving bed biofilm reactor (MBBR) configuration (oxic-anoxic and oxic) with 10% filling fraction of biomass carriers was operated in a continuously fed regime at temperatures of 25, 20, 15 and 6 °C with hydraulic retention times (HRTs) of 32 h, 18 h, 12 h and 9 h, ...

Improvement of an Industrial Wastewater Treatment System at a Former Viscose Rayon Plant – Results From Two-Stage Biological Leachate Treatability Testing

Leachate is currently being pumped from three surface impoundments filled with waste material from the production of viscose rayon at the former Avtex Fibers plant. The primary objective of this study was to optimize a two-stage biological treatment process that has the potential to effectively treat a wastewater stream containing high levels of reduced sulfur compounds while also removing ...

Optimization of operational parameters in moving bed biofilm reactor with low cost polystyrene biocarrier by the response surface method

The combined effects of three independent variables (carrier filling ratio, aeration rate and reactor run time (RRT)) were evaluated in a continuous moving bed biofilm reactor (MBBR) through central composite design (CCD) of the response surface methodology (RSM) for experimental design, analysis and process optimization for municipal wastewater treatment processes. A low-cost polystyrene ...
