The Hazen Lab is a diverse group research associates, post doctoral fellows, research associates, graduate students, undergraduate students, and visiting professors in microbial ecology and environmental engineering that are led by Dr. Terry C. Hazen. The overarching theme of our research is Systems Biology from Ecosystems to molecules, because the whole is greater then the sum of its parts. Conventional downflow filters are limited to flow rates of 2 to 5 gal/min-ft 2 and total solids loads (before backwashing) of 1/2 to 1 1/2 lbm/ft 2. With appropriately designed distribution systems, high-rate filters can be operated at 7 to 15 gal/min-ft 2. Full text of "A Text-book of Applied Mechanics." See other formats. Comparison of high-rate anaerobic wastewater treatment reactors. The four reactors reviewed in this book are similar in that each is a means of maintaining the active biomass independently of the hydraulic retention time in the fermentation process.

Biofilm Reactor Technology and Design model, high-rate MBBRs typically are designed to receive a filtered BOD5 load in the range 15 to 20 g/m2 d at 15°C. This corresponds to total-BOD5 loads as high as 45 to 60 g/m2 d at 15°C (Ødegaard, ). Such high surface area loadings, however, result in short hydraulic residence time (HRT). Filters are categorized as follows: the low rate is 1,5 to 4 m3 per m2 per day, the intermediate rate is 4 to 10 m3 per m2 per day, the high rate is 10 to 30 m3 per m2 per day, and super-rate.

High-rate biological treatment processes, in combination with primary sedimentation, typically remove 85 % of the BOD 5 and SS originally present in the raw wastewater and some of the heavy metals. Activated sludge generally produces an effluent of slightly higher quality, in terms of these constituents, than biofilters or RBCs.

Several studies related to TFs have determined the effects generated by changes in operating conditions in the water purification process, such as hydraulic load, Q, m 3 /m 2 d; organic load, L, kg COD/m 3 d; and temperature (Gebert and Wilderer, ). The increase in organic or hydraulic loads leads to a decrease in removal efficiency. Unfortunately, this book can't be printed from the OpenBook.

Biological aerated filters are wastewater-treatment systems which contain support media for the development of a biofilm and provide oxygen at the base of the reactor for aerobic microbial processes.

Trickling filters and rotating biological contactors: attached growth processes Diederik Rousseau Tineke Hooijmans This presentation is based on lecture notes of dr. Peter van der Steen, UNESCO-IHE. The biological kinetic behavior of completely mixed air and oxygen systems was studied and compared in both batch and continuous flow once-through (varying different dilution rates) operations.

Explores the fundamental concepts of sustainable wastewater treatment; Uses the concept of mass balance to develop models applicable to various unit processes.

This includes processes such as waste stabilization lagoons, trickling filters, rotating biological contactors, and activated sludge. In most cases wastewater treatment is accomplished through the use of a combination of physical/chemical and biological treatment processes. For instance, a typical.

Mass Transfer and Kinetic Considerations The overall performance of fixed film processes including the RBC is influ- enced by both mass transfer and biological kinetic considerations.
