Southern Water operates 370 wastewater treatment plants (WWTP), many of which are unmanned for most of the time and most have numeric environmental permits, so a network of online monitors has been established to improve treatment and protect discharge compliance. This has involved the installation of final effluent monitors at over 300 sites in a ...

Having an eff ective, durable pretreatment system in advance of ion exchange produced-water softening systems is the fi rst, most critical line of defense – ensuring smooth, more troublefree performance downstream. It’s especially true when dealing with today’s ion exchange technologies, which require TSS (total suspended ...

Urbanization and frequent storms play important roles in increasing faecal bacteria pollution, especially for tropical urban catchments. However, only little information on the faecal bacteria levels from different land use types and the factors that influence bacteria concentrations is available. Thus, the objectives of this study were to ...

In the present paper the detailed design and performances of two municipal wastewater treatment plants, a four-stage constructed wetlands (CW) system located in the city of Dicomano (about 3,500 inhabitants) in Italy, and a three-stage CW system for the village of Chorfech (about 500 inhabitants) in Tunisia, are presented. The obtained results ...

Treatment of agricultural drainage water (ADW) in a down-flow hanging sponge (DHS) reactor has been investigated for a period of 1 y. The reactor was operated at different hydraulic retention times (HRTs) of 5.26, 2.63, and 1.5 h and corresponding organic loading rates (OLRs) of 2.01, 1.86, and 4.43 kg COD/m3 d, respectively. The results ...

The impact of changing microwave (MW) operational parameters such as temperature, intensity, contact time, and sludge concentration on the physic–chemical and microbiological properties of waste activated sludge (WAS), as well as on biogas production have been investigated. Results obtained indicated that sludge solubility increases with the ...

The "North Slope" of Alaska is one of the harshest environments in the world to survive in, let alone work in, on a daily basis. Temperatures can reach -70 degrees F and wind chill factors can reach -100 degrees F. The "Slope" is home to thousands of oilfield workers, many of who live in portable camps located in extremely remote locations. In ...

In the spring of 2006, Williamson County, Tennessee officials were approached about the possibility of the development of the first winery in the county. Co-owned by country music celebrity Kix Brooks (half of the superstar duo Brooks and Dunn), Arrington Vineyards was proposed in the small-unincorporated community of Arrington, which has no ...

Researchers have paid particular attention to the disposal of sludge produced in water treatment plants (WTPs) into wastewater treatment plants (WWTPs) for further processing, mainly because it is considered an attractive alternative for the treatment of waste generated in water production processes. This study evaluated the effects of flow ...

We demonstrated a general relationship between water quality index (WQI) values and indices of benthic community composition for a set of 32 streams from British Columbia and Ontario. Streams that produced lower WQI values tended to have benthic communities characteristic of degraded water quality. Streams, in contrast, that produced higher WQI ...
