Through an environmental and economic point Membrane Filter Plates

601 tonnes of treated sludge dry matter that is recovered or upgraded in 2011. It is stabilizing currently. The survey recorded records corresponding to 123.. For 9% of most of these, these effluents represent between 21 and 30% belonging to the flows. 34% of the communities do not know the percentage of industrial water received for their treatment plants.,according to the Ministry involving Ecology, Sustainable Development and Vigor. The association conducted among its members a study into their choices regarding sludge management. "

The centrifugation technique is extra used than the filter press which is less suitable for all types of treatment plants - heavier to use, less automatable", note Membrane Filter Plates Manufacturers Primer. In contrast, at the national level, the actual Sludge deposit from Step presents 1. For the query of treatments, the state of primer unveils that dehydration alone and in combination with the thickening remain the a lot of used solutions. 1 million tonnes of dry matter truly.

Direct spreading, composting or anaerobic digestive function, the results of the study show that the majority of the sludge goes back to this ground. Population growth, improved efficiency of urban wastewater treatment plants and increase from the connection rate to collective sanitation sites, production increased between 1999 as well as 2007. For the majority (57%), nonetheless, this share remains below 20% from the total volume treated.

Through an environmental and economic point of view, organic recovery of sludge from urban wastewater treatment plants (Step) can be an interesting solution for communities, in line with a study by Primer, publicized in November 2012. 22 Step receive industrial wastewater Regarding the effluents, twenty-two of the interviewed communities receive industrial wastewater within their step
