Poly (Ε-caprolactone) as substrate for water denitrification
In this paper, poly (Ε-caprolactone) (PCL) was used as carbon source and biofilm supporter in a fixed bed bioreactor to biologically remove nitrate from drinking water. The experimental results showed that denitrifying microorganisms could easily adapt to PCL as carbon source and attach to the surface of PCL granules. The fine biofilm could form on the surface of PCL granules within 15 days. ...

Intrinsic kinetics for fixed bed bioreactor in hospital wastewater treatment
Variation in hospital wastewater (HWW) pollutants and differences with municipal wastewater (MWW), make the use of biokinetic coefficients obtained from activated sludge in the MWW treatment unprofitable for designing, modeling and evaluation of biological processes for HWW treatment. Since this study was conducted to evaluate the performance and biokinetic coefficients of a fixed bed ...

What are Bioreactors?
Bioreactors are vessels in which raw materials are converted to product by the action of living organisms. A bioreactor provides the optimal environment for cells and microorganisms to grow by maintaining pH, temperature, gas, and nutrient supply. What is the Difference Between a Bioreactor and Fermentor? The word ‘Bioreactor’ is often used as a blanket term. However, when the process ...

Evaluation of different configurations of hybrid membrane bioreactors for treatment of domestic wastewater
Four membrane bioreactors (MBRs) with the same dimensions were studied for 180 days: three hybrid growth membrane bioreactors with biofilm attached in different packing media and a conventional MBR (C-MBR). The four MBRs had an identical membrane module of hollow fiber with a nominal porous diameter of 0.4 μm. The MBRs were: (1) a C-MBR; (2) a moving bed membrane bioreactor (MB-MBR), ...

Wastewater Treatment Process
The wastewater treatment process is complex and critical to civilization. In simplest terms, wastewater is water that has been mixed with waste matter. Wastewater can be classified as domestic, municipal, or industrial based upon the source of generation. For instance, domestic wastewater comes from everyday liquid waste, including water used to flush the toilet, to shower, or to wash dishes. ...

Effect of the chemical nature of fixed-bed reactor support materials on bioreactor performance and biomass accumulation
This study investigated the effect, on reactor performance and biomass retention inside the bed, of the material used to make the supports of anaerobic fixed-bed reactors. Three inert supports of similar shape but made of three different materials polyvinyl chloride, polypropylene, high-density polyethylene were manufactured and used. All three supports had the same specific surface area but ...

Synergistic application of advanced primary and secondary wastewater treatment systems
Published in Water and Waste Digest membrane issue, November 2008 Miroslav Colic; Chief Scientist, Clean Water Technology Inc., Los Angeles, CA To be published in Water and Waste Digest later this year The increased regulatory pressures and demand for reused water stimulated development of several new wastewater technologies in the last decade. Advanced treatment systems are characterized by ...
