French legislation requires the control of private on-site sanitation systems by local authorities. This will result in a large increase of the quantity of sludge from septic tanks to be treated. Nevertheless, large wastewater treatment plants are not systematically able to treat this sludge because they may have reached their nominal load or they are not so numerous in rural zone to avoid too ...

Transmissible spongiform encephalopathies (TSEs, prion diseases) are a class of fatal neurodegenerative diseases affecting a variety of mammalian species including humans. A misfolded form of the prion protein (PrP(TSE)) is the major, if not sole, component of the infectious agent. Prions are highly resistant to degradation and to many disinfection procedures suggesting that, if prions enter wa...

Septic systems are used for wastewater treatment in rural areas. tanks promote stratification of into solid (sludge and scum) liquid layers. Pollutant concentrations the layers residential septic may be highly variable, thus septage pumped from with different layer thicknesses also variable. The goal this study was to quantify total phosphorus (TP) heavy metal masses septage. were measured 37 t...

Mixed-microbial assemblages enriched from a septic tank, coastal sediment samples, the digester sludge of a brewery wastewater treatment plant and acidic sulfate soil samples were compared on the basis of growth rate, waste and sulfate reduction rate under sulfate reducing conditions at 30 degrees C. The specific growth rate of various cultures was in the range 0.0013-0.0022 hr(-1). Estimates o...

The current paper assesses the reliability coefficients of fifty six low-cost, full-scale wastewater treatment plants, including nine different treatment technologies for wastewater reuse in aquaculture and agriculture in northeast Brazil. This was carried out with the aim to evaluate alternatives for sustainable wastewater reuse in communities experiencing water scarcity. The technologies eval...

Seven years of monitoring groundwater in the Gaza Strip has shown that nitrate was and still is a major groundwater pollutant. The objectives of this research were to study the distribution of NO(3)(-) in the groundwater of the Gaza Strip and to identify the sources of NO(3)(-) in the Gaza aquifer system by assessing nitrogen and oxygen isotopes. The most recent samples collected in 2007 showed...

background and objectives: hydrocortisone is widely used in septic shock cases resistant to fluid and vasopressor therapy. it may result in increased blood pressure and survival. however the efficacy is no established among patients with severe burn and septic shock. accordingly it was assessed in this study. materials and methods: the patients older than 14 years of age with resistant septic s...

The construction of a Sludge Treatment Plant (IPLT) is one the efforts made to treat fecal sludge and control pollution environment from housing settlement activities. city Sabang already has an IPLT which was built in 2013 but due influent still very minimal, there high idle capacity (100%). non-operated causes condition function processing units deteriorate. purpose this study evaluate post-c...
