Treatment of tunnel wash water and implications for its disposal
The use of road tunnels in urban areas creates water pollution problems, since the tunnels must be frequently cleaned for traffic safety reasons. The washing generates extensive volumes of highly polluted water, for example, more than fivefold higher concentrations of suspended solids compared to highway runoff. The pollutants in the wash water have an affinity for particulate material, so ...

Rapid inactivation of
Salmonella by a quaternized biopolymeric flocculantWe report the characteristics and biocidal properties of a biopolymeric flocculant produced by Klebsiella terrigena capable of flocculating Salmonella efficiently from water. In order to impart an antimicrobial function, the native biopolymer was quaternized and the trimethyl biopolymeric derivative (TMB) was analysed physically, chemically and for flocculating properties. The quaternized ...

Case study - Vestfjorden Sewage Plant (Veas)
In Norway’s largest sewage plant, Veas in Oslo, Filtralite* has proven extremely durable as both bio substrate and sludge filtering medium. After 25 years of operation with daily back flushing there is no need for replenishing. A river of sewage of maximum 11 m3 second runs in a 42 kilometre underground tunnel, collecting sewage from Oslo centre to Slemmestad in Asker, where the ...

Wastewater pre-treatment in a confectionery industry
Description of the plant In a first step, wastewater accruing from the production of marzipane is cleaned by a screen. As flow and load to the plant are highly variable depending on the production process an aerated mixing and balancing reactor has been installed to equalise flow and load before final chemical pre-treatment. After adding of chemicals for precipitation and flocculation in special ...

Wastewater-Primary Treatment
Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...

Water purification
Water purification is a process of removing undesirable chemicals, materials, and biological contaminants from raw water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (Drinking water) but water purification may also be designed for a variety of other purposes, including meeting the requirements of medical, pharmacology, chemical and ...

Microalgae growth for nutrient recovery from sludge liquor and production of renewable bioenergy
Proof-of-concept has been demonstrated for a process that will utilize nutrients from sludge liquor, natural light, and CO2 from biogas to grow microalgae at wastewater treatment plants. This process will reduce the impact of returning side-streams to the head of the plant. The produced algae will be fed to anaerobic digesters for increased biogas production. Dewatering of anaerobically digested ...

Simple laboratory techniques improve the operation of RO pre-treatment systems
Membrane failures are often caused by poor pre-treatment design and/or poor operation. Systems are frequently designed and built without a clear understanding of the chemistry of the feed water to be treated and the physical characteristics of the particulate matter it contains. The larger the system the more likely is some incident of pre-treatment failure, often at a high financial cost to the ...

Water quality monitoring following Hurricanes Katrina and Rita
Following the passage of Hurricane Katrina, New Orleans was left with 80% of its land area flooded. In some locations, the flood waters were over 30 feet deep. In the heat and stagnation, the waters quickly became heavily polluted. Pump out operations began in early September 2005 to get the city dried out quickly. Lake Pontchartrain was the primary receiving water body. A variety of approaches ...
