The phenomenon of red mud residues thrown Membrane Filter Plates

The Alteo plant, threatened with closure in Late 2015, will be able to keep, on prefectural order and feeling of government maneuvers, to dispose of its ocher damage at seaside. Is the concern resolved?.

After a bitter debate in the 20th century, discussions continue inside the 21st. But the prefecture of Bouches du Rhone, after opinion in the Higher Council of the deterrence of technological risks, decided if not.

The following? Many of us know it. From the beginning of the installation of the Péchiney plant into the refusal of Nicolas Hulot to enter the federal government of Manuel Valls as Minister of Ecology, the phenomenon of red mud residues thrown into the sea reached its peak in 1966 and the construction of a pipeline above 50 kilometers long.

The actual French state has ten weeks to Filter Plates

Its extraction is made out of bauxite ore, red color, formerly discovered Filter Plates Manufacturers in Baux-de-Provence and now imported from Guinea, thanks with a chemical process based on soft drinks.

The actual French state has ten weeks to react to Europe. A 55-kilometer pipeline still plunges slightly over 7 kilometers from this coast, off Cassis, up to 320 meters deep while in the Cassidaigne Canyon. An aluminum-iron-arsenic cocktail has already been planned in the program. For fifty years, the Gardanne factory had poured to the sea the residual red mud of these industrial process, loaded with large metals. But since January 1, at the end of an epic saga science-political, it is actually finished toxic sludge. For the chemical has just obtained a waiver through the prefecture of Bouches-du-Rhone to carry on discharging its discharges, only liquid this time around, its industrial rinsing water in some manner. Well pretty much.

That they start by putting it for their pool rather than rotting the particular Mediterranean with, "fumed Gérard Carrodano, 1st prud'homme professional fishermen of La Ciotat (Bouches-du-Rhone). This component can be used in the manufacture of ceramic and also refractory materials and high-tech a glass. They show us a jar with clear water from it. The jar that bristles the scales is one that has taken to brandishing the representatives on the company Alteo-Alumina, in Gardanne, world leader within the production of specialty aluminas, to help prove their efforts in issues of rejects.

 Paradoxically or even cynically, the situation is bettering. Them exceeds regulatory standards, but carries a French state laissez-passer. Opened in 1893, the Gardanne manufacturing plant, long stamped Pechiney, produces alumina.. But all that is clear is just not harmless. The NGOs Sea Sheperd, Surfrider as well as League for the Protection regarding Birds (LPO), meanwhile, ask with the cancellation "pure and simple" of the prefectural decree of 28 12 , 2015

We have questioned the Minister with the Environment Filter Presses

At the end of this specific period, no pollutant should no more be rejected at sea. Altéo, after 50 many polluting "red mud" discharges at sea, obtained Filter Presses Manufacturers at the end of November a new prefectural authorization. "This furious madness may be going on for 60 many years (...Taking into account this technique, the prefecture granted a derogation to the firm, authorizing it to refrain from these liquids for six a long time.

Ségolène Royal had disapproved on the decision to authorize again the particular discharge of effluents, which she said was taken because of the prefect on "direct" order involving Prime Minister Manuel Valls.. This company has been authorized by the state to remain discharges of effluents into the waters in the Parc national des Calanques. About a thousand people gathered this Saturday as you're watching prefecture of Bouches-du-Rhone in Marseille to denounce "the scandal of red mud" spilled in the Mediterranean by the industrial Altéo.) We do not cherish the Marseillais, the fishermen and hundreds of who live by the seaside, " said MEP José Bové, present in the rally.

But many local associations have objected to the derogation, believing that the problem associated with water pollution still exists and pointing to your lack of will of Alteo. Environmentalists believe "job blackmail" - the Gardanne seed employs 400 employees and THREE HUNDRED subcontractors - has led that Prime Minister to ignore the position of the Minister of the Environment. "We have questioned the Minister with the Environment (Ségolène Royal):

I hope we will have a clear announcement to halt this scandal" releases of arsenic in addition to heavy metals at sea, they added. It has modified its operations and rejects a filtered liquid that opponents continue to keep consider as pollutant

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

On account of this PLC-driven approach Membrane Filter Plates

The union contracted a mortgage loan of 100, 000, the sense of balance being self-financing. The company Alteo, designer of alumina, will finally have the ability to reject its residual liquid effluents off the national park of Calanques: that prefect of Bouches-du-Rhône signed at Monday, December 28 a decree supplying a derogation for six years to the industrialist.

Figures that leave a fantastic margin for connecting new members. Wastewater, the moment decanted, becomes sludge. "The system works constantly, automatically, " explains Jean-François Starck. A polymer is added and they also pass through a filter hit. Membrane Filter Plates The resolution was to optimize the wastewater therapy cycle. However, the company had committed throughout 1996 to cease discharges at sea adjusted December 31, 2015, an initiative then confirmed by way of prefectural prohibition order at that time.

On account of this PLC-driven approach, the processing capacity increases from 8 m³ everyday to 40 m³ in almost 12 hours. The total amount of this works was 280 000 before tax. As a result, the construction of the new facility was considered, which can have generated significant costs. She falls directly suitable trailer that will take her with a storage area, before being applied as fertilizer on farmland. Lime is included with the compressed sludge to make it inert..

The water agency supplied 78, 500 in grants, while the General Council contributed 46, 500.Inaugurated inside November 2001, the treatment capacity from the treatment plant had become very low, making its operation complicated. The residual water is pushed on the periphery of the press, in advance of returning to settling
