Treatment of wastewater from a school in a decentralized filtration system by percolation over organic packing media
Based on results obtained in the laboratory a WWTP composed of a septic tank and an aerated percolating filter packed with organic media was built for a school. The system can treat 18 m3 d−1 and was operated with a hydraulic loading rate of 0.078 (m3 m−2 d−1). For 360 days different operational conditions including start-up; stabilization; operation with aeration and non aeration; effect of ...

Alkaline fermentation of waste activated sludge stimulated by saponin: volatile fatty acid production, mechanisms and pilot-scale application
Volatile fatty acid (VFA) production stimulated by saponin (SP), an environmentally friendly bio-surfactant, was investigated during sludge alkaline fermentation in laboratory studies and pilot applications. The combined use of SP and pH 9 condition significantly enhanced VFA production to approximately 425 mg COD/g VSS, which was 4.7-fold of raw sludge and 1.5-fold of sole pH 10 adjustment ...

Dynamics of
Aeromonas species isolated from wastewater treatment systemAeromonas are widely distributed in the aquatic environment, and are considered to be emerging organisms that can produce a series of virulence factors. The present study was carried out in a sanitary sewage stabilization pond treatment system, located in Lins, State of São Paulo, Brazil. Most probable number was applied for estimation of the genus Aeromonas. Colony isolation was carried out on ...

Ojai Valley, CA – Ojai Valley Sanitary District Case Study
The Ojai Valley Sanitary District (OVSD) wastewater treatment facility processes an average 1.8 MGD of wastewater per day which is then either reused for irrigation or discharged to the Ventura River. In 2010, the award winning treatment facility initiated a new program to further improve its treated effluent by removing nitrate concentrations to very low level. As part of the initiative, ARoNite ...

Wetland Biofilter System provides year-round, cost effective treatment to over 1.5 million litres of wastewater
The success of early surface flow treatment wetlands in Canada was limited by hydraulic blockages and oxygen limitation due to freezing. From 1991 to 1996, Dr. Edgar Lemon, with the Friends of Fort George, researched a sub-surface vertical flow constructed wetland treating lagoon effluent at Niagara-on-the-Lake, funded by the Ontario Ministry of Environment (MOE) and the United States ...
