Development of a compact, cost effective, and energy efficient biofilm reactor for wastewater treatment and effluent reuse

by Biowater Technology  (Aug. 19, 2014)

Abstract The CFIC (Continuous Flow Intermittent Cleaning) biofilm reactor has been developed. It contains highly packed biofilm carriers to a degree that little movement of the carriers occurs in the reactor during normal operation. The process has continuous inflow to the bioreactor and intermittent cleaning, which removes excess biomass from the ...

Characterization and first flush analysis in road and roof runoff in Shenyang, China

by IWA Publishing  (Aug. 7, 2014)

As urbanization increases, urban runoff is an increasingly important component of total urban non-point source pollution. In this study, the properties of urban runoff were examined in Shenyang, in northeastern China. Runoff samples from a tiled roof, a concrete roof and a main road were analyzed for key pollutants (total suspended solids (TSS), ...

Flocculation performance of magnetic particles with high-turbidity surface water

by IWA Publishing  (Aug. 6, 2014)

The sharp increase in raw-water turbidity following heavy rain presents considerable treatment problems due to low sedimentation rates. The objective of this study was to evaluate the removal of negatively charged suspended solids (SS) in surface water treatment using magnetic particles (nFeO; FeO · Fe2O3) synthesised in our laboratory. ...

Development of a down-flow hanging sponge reactor for the treatment of low strength sewage

by IWA Publishing  (Aug. 13, 2014)

The process performance of a down-flow hanging sponge (DHS) reactor for treating low strength sewage (biochemical oxygen demand (BOD) 20–50 mg/L) was investigated in Bangkok, Thailand. The hydraulic retention time (HRT) was set at 4 h during the start-up period and was reduced to 1.5 h in a stepwise manner. Throughout the 300-day ...

Results of EcoCatalyst Injection into SBR`s Creamery Plant, in Texas, USA case study

by EcoJump LLC  (Aug. 19, 2014)

EcoCatalyst Injection Into SBR's -Primary Project Objectives: Monitor EcoCatalyst ability to increase the transfer of dissolved oxygen into the North and South SBR’s and it’s “carry over effect” into the aeration lagoons. Observe the improvements in percentage removal of COD and TSS in SBR’s and Total Plant Removal ...

Sludge accumulation in shallow maturation ponds treating UASB reactor effluent: results after 11 years of operation

by IWA Publishing  (Jul. 23, 2014)

Polishing ponds are natural systems used for the post-treatment of upflow anaerobic sludge blanket (UASB) effluents. They are designed as maturation ponds and their main goal is the removal of pathogens and nitrogen and an additional removal of residual organic matter from the UASB reactor. This study aimed to evaluate organic matter and ...

Analysis of nitrogenous and algal oxygen demand in effluent from a system of aerated lagoons followed by polishing pond

by IWA Publishing  (Jul. 16, 2014)

In this descriptive-analytical study, nitrogenous and algal oxygen demand were assessed for effluent from a system of facultative partially mixed lagoons followed by the polishing pond using 120 grab samples over 1 year. Filtered and non-filtered samples of polishing pond effluent were tested in the presence and absence of a nitrification ...

Pilot trial study of a compact macro-filtration membrane bioreactor process for saline wastewater treatment

by IWA Publishing  (Jul. 16, 2014)

Conventional membrane bioreactor (MBR) systems have increasingly been studied in recent decades. However, their applications have been limited due to their drawbacks such as low flux, membrane fouling, and high operating cost. In this study, a compact macro-filtration MBR (MfMBR) process was developed by using a large pore size membrane to ...

Operation of an integrated algae pond system for the treatment of municipal sewage: a South African case study

by IWA Publishing  (Jun. 25, 2014)

Integrated algae pond systems (IAPS) combine the use of anaerobic and aerobic bioprocesses to effect sewage treatment. In the present work, the performance of IAPS was evaluated to determine the efficiency of this technology for treatment of municipal sewage under South African conditions. Composite samples were analysed over an 8 month period ...

GWT Case Study - Produced Water - Oil/Gas Industry

by Genesis Water Technologies, Inc  (May 23, 2014)

GWT Case Study - Produced Water  Treatment/Reuse - Oil/Gas Industry Challenge A large oil processing company wanted to reuse their produced water from several oil wells applications. The water contained hydrocarbons, sulfate, TSS, BOD/COD, dissolved salts and high levels of iron ...
