Biofilm carriers / MBBR carrier media and their respective diffusion depth

Within the biological wastewater treatment sector, it can increasingly be observed that biofilm carriers are applied in so-called Moving Bed Biofilm Reactors (MBBR). Thereby, the MBBR process is not only used to great success for the purification of domestic sewage but also in the sector of industrial wastewater and aquaculture systems. The availability of high-performance ...

Biofilm regeneration on carriers in MBBR used for vitamin C wastewater treatment

Methods were investigated for biofilm regeneration on carriers in a moving bed biofilm reactor used for vitamin C production wastewater treatment. Three ordinary chemical cleaning agents (hydrochloric acid, sodium hydroxide, and sodium hypochlorite) and physical drying were chosen for evaluation as methods for biofilm detachment. The results showed that these methods all had some degree of ...

Removal of phosphorus and residual aluminium with the simultaneous use of chitosan and alum on the effluent of an MBBR biological system during start–up

Physico–chemical treatment with aluminium salts is a common practice to remove total phosphorus (TP) from wastewaters. However, the use of alum can increase the residual aluminium concentration both in the effluent and biosolids. Chitosan, an alternative coagulant, does not allow for the removal of TP below the requirement level when lower than the soluble phosphorus fraction of the water. Hence, ...

Army Truck Wash Depot case study

The Problem: The Army Truck Wash Depot had a trickling filter that was not capable of handling the organic loading generated by heavy vehicle wash operation. The tricking filter was channeling the wastewater due to media that had been crushed by the weight of the biomass that could not be sloughed off. As a result, the ability to treat the wastewater for BOD ...

Pilot scale studies on nitritation-anammox process for mainstream wastewater at low temperature

Process of partial nitritation-anammox for mainstream wastewater at low temperature was run in a pilot scale moving bed biofilm reactor (MBBR) system for about 300 days. The biofilm history in the reactor was about 3 years of growth at low temperature (down to 10 °C). The goal of the studies presented in this paper was to achieve effective partial nitritation-anammox process. Influence of ...

7 Disadvantages of Implementing an Activated Sludge Process For Your Municipality or Company

Biological treatment processes are an important component in many wastewater treatment systems. They are one of the most efficient and effective ways of reducing organic material in wastewater. There are quite a few of them that have been researched and used over several decades. However, one of the most widely used conventional biological treatment process is the activated sludge process (ASP). ...

Partial nitrification in MBBRs for mainstream deammonification with thin biofilms and alternating feed supply

A new principle for mainstream nitrogen removal through nitritation followed by anammox was studied in a two-stage moving bed biofilm reactor (MBBR) configuration. The first stage was optimized for nitritation by using thin biofilms and a feed alternating between synthetic mainstream wastewater at 15°C and, for shorter periods, synthetic reject water at 30 °C. The exposure of the biofilm to ...

MBBR and IFAS PILOT Program for denitrification at Fairfax county’s Noman Cole Pollution Control Plant

ABSTRACT As part of a nutrient reduction program, developed to meet new Virginia ENR requirements, two innovative denitrification technologies were piloted at the Noman Cole Jr. Water Pollution Control Plant in Fairfax County, Virginia. The first technology was a Moving Bed Biofilm Reactor (MBBR). The second technology was a modified Integrated Fixed Film Activated Sludge (IFAS) ...

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 ...

Impact of fine mesh sieve primary treatment on nitrogen removal in moving bed biofilm reactors

The purpose of this project was to investigate the effect of selective particle removal during primary treatment on nitrogen removal in moving bed biofilm reactors (MBBRs). Two small MBBR pilot plants were operated in parallel, where one train treated 2 mm screened municipal wastewater and the other train treated wastewater that had passed through a Salsnes Filter SF1000 rotating belt sieve ...

Protein to polysaccharide ratio in EPS as an indicator of non-optimized operation of tertiary nitrifying MBBR

The protein (PN), polysaccharide (PS), and extracellular DNA (eDNA) percent concentrations of extracellular polymeric substances (EPS) of biofilm samples harvested from a pilot-scale nitrifying moving bed biofilm reactor (MBBR) were investigated at various operating temperatures and hydraulic retention times (HRTs). Chemically measured EPS PN/PS ratios were shown to correlate to Raman ...

Rotating belt sieves for primary treatment, chemically enhanced primary treatment and secondary solids separation

Fine mesh rotating belt sieves (RBS) offer a very compact solution for removal of particles from wastewater. This paper shows examples from pilot-scale testing of primary treatment, chemically enhanced primary treatment (CEPT) and secondary solids separation of biofilm solids from moving bed biofilm reactors (MBBRs). Primary treatment using a 350 microns belt showed more than 40% removal of ...

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

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 ...
