Repurposing Composting Infrastructure

A Vermont solid waste district utilized a defunct biosolids composting site to create capacity for processing food waste. The Vermont legislature instituted a progressive ban on organics in landfills via Act 148 in 2012. The Act includes the provision that transfer stations/drop-off facilities must accept food scraps by July 1, 2017. The Lamoille Regional Solid Waste Management District (LRSWMD) ...

A simulation of the fate of nitrogen in an on-site wastewater treatment system

An experiment to study and to build a mathematical model to reproduce the behavior of nitrogen in a residential wastewater treatment process was performed. A pilot unit receiving grey and black water was used. The pilot consisted in a septic tank followed by a fixed-film, partly aerated bioreactor with effluent recirculation operated under two different scenarios: normal operating conditions and ...

Effectiveness of Alternative On-Site Wastewater Treatment Technologies

ABSTRACT New York City’s drinking water supply is threatened by the potential development of the Catskill/Delaware watershed. The effectiveness of alternative on-site wastewater treatment systems in this drinking water supply watershed is being evaluated during the course of a oneyear field study. Twenty-four on-site systems were designed and installed for individual sites throughout the ...

Waste Water Treatment Plants

In 1980, Los Angeles began exploring alternatives to control the H2S concentration in the digester gas produced at the Hyperion Waste Water Treatment Plant (WWTP), which treats nearly 420 MGD, wastewater generating over 475 tons of raw sludge per day. The digester gas H2S concentration had to be controlled so that the SOx emissions from the on-site combustion of the gas could be kept within ...

Water treatment in Brazil

The challenge Many factories in Brazil do not dispose their sewerage in a professional way. Only big enterprises use facilities to treat their industrial waste water, whereas numerous small and medium-sized enterprises convey their sewerage flow into rivers and brooks or pit drainages. This results in a significant environmental burden and endangers the health of the population. ...

The importance of Water Treatment in industry

Water treatment is an important industry requirement and comes under 4 main branches which include boiler water treatment, cooling water treatment, water purification and the treatment of wastewater effluent. It is considered that these cover the majority of Water treatment processes in the UK and Internationally. Water treatment is often seen as an additional cost on top of an already very ...

The Daytona Beach Ralph Brennan Water Treatment Plant Finds On-Site Generation to be a Safe and Economical Solution for Water Disinfection

ABSTRACT For many years the use of gaseous chlorine at water treatment plants has been an effective and widely used method of disinfection. It is still the most commonly used disinfectant treatment in water treatment plants in the United States. In recent years however, the safety of chlorine gas has come under increased scrutiny. The side effects to chlorine gas exposure at low levels ...

Real–time management of odour on water treatment plant using a 3D simulation tool coupled to on–site sensors

In order to forecast and to follow the dispersion of odours around its treatment sites, SIAAP which treats wastewater for the entire region around Paris, developed and implemented an innovative tool called SYPROS. SYPROS is based on the 3D CFD dispersion tool Fluidyn–PANEIA and uses a Lagrangian puff model for real time calculations, together with a source definition module for determining ...

Efficacy of drinking-water treatment residual in controlling off-site phosphorus losses: A field study in Florida

Received for publication August 23, 2008. Land application of drinking-water treatment residuals (WTR) has been shown to control excess soil soluble P and can reduce off-site P losses to surface and ground water. To our knowledge, no field study has directly evaluated the impacts of land application of WTRs on ground water quality. We monitored the effects of three organic sources of P (poultry ...

Institutional trajectory for diffusing on-site wastewater treatment in urban China

Urban water scarcity has been an issue for a long time in China while water pollution has attracted more and more attention over the last two decades. Recently, on-site wastewater treatment (OST) has been proposed as a meaningful alternative to deal with both water pollution and water scarcity in cities in a more sustainable way. However, the diffusion of such an OST system is still slow and ...

Long-term hygienic barrier efficiency of a compact on-site wastewater treatment system

Received for publication September 11, 2008. The long-term use of a filter-based, on-site wastewater treatment system increases nutrient discharge to receiving waters and may reduce its hygienic barrier efficiency. The main purpose of this research was to assess the hygienic barrier efficiency and the associated health risks of an on-site system that had exceeded its 5-yr design capacity with ...

Development of an on-site Fe0 system for treatment of copper- and zinc-contaminated roof runoff

The objective of the present work was to develop an on-site Fe0 system for treatment of metal-contaminated roof runoff. Breakthrough experiments were performed under laboratory flow-through conditions using runoffs that have varying water quality parameters. Phase analyses and the chemical-equilibrium model were employed for describing the removal mechanisms. ...
