Patent number: 6861041Abstract: A method for treating and upgrading effluents containing at least a metallic sulphate comprising adding at least a base to the effluent to precipitate the metallic ions in the form of iron oxy-hydroxides Fe(OHx) wherein x=2 and/or 3; separating the precipitated hydroxide calcium sulphate CaSO4; and separating the calcium sulphate CaSO4 precipitated during the preceding step. Said method enables obtainment of calcium sulphate (white gypsum) substantially free of metals and therefore capable of being upgraded and iron oxy-hydroxides likewise capable of being upgraded.Type: GrantFiled: April 17, 2001Date of Patent: March 1, 2005Assignee: Sarp IndustriesInventors: Francois Hyvrard, Pascal Muller

Patent number: 6314895Abstract: A method for treating at least one liquid fluid comprising a high water content, and including a volatile fraction and a heavy fraction, in order to separate said two fractions. Said method consists in burning at least one gas fluid, recuperating the heat released by said combustion for subsequently heating the liquid fluid. The heated liquid fluid is pressurised and then expanded so as to separate the volatile fraction from the heavy fraction. The volatile fraction is then burnt with the gas fluid. The heavy fraction is extracted from the process to be subsequently treated. The invention also concerns an installation for implementing the treatment method.Type: GrantFiled: January 16, 2001Date of Patent: November 13, 2001Assignee: Sarp IndustriesInventors: Jean-François Nogrette, Bernard Lefebvre, Jean-Guy Notelteers, Jean-Paul Leglise

Patent number: 5347930Abstract: The disclosure relates to a method and installation for the destruction and of containers containing dangerous and noxious laboratory wastes, by explosion in a submerged medium. The automatic treatment installation comprises: at least one basin filled with water for submersion of the containers; means for the automatic conveyance and subsequent submersion of the baskets carrying waste containers; explosion means (explosive fuses and detonators); these means being integrated into a whole complex comprising: an area for the loading of the baskets; a room for the storage of explosives and a room for the storage of the detonators, with safety areas; and a system for the recovery of the broken containers. This method and installation can be applied to the destruction of wastes and products from all laboratories chemicals facilities.Type: GrantFiled: February 24, 1992Date of Patent: September 20, 1994Assignee: SARP IndustriesInventors: Pierre Baronquel, Jean-Louis Biros

Patent number: 5276252Abstract: The disclosure relates to the field of the storage of toxic wastes, in solidified form, without the creation of any pollution, on appropriate artificial sites. Briefly, a concrete raft is cast on a ground stabilized in depth, said concrete raft being constituted by slabs having joints between them and being arranged in a diamond moulding. This raft can support a tight-sealing material. Wastes are then piled up on the raft in maintaining the shape of a tumulus-like mound, the positioning being done under the protection of a movable cover comprising a travelling crane provided with rolls of plastic film.Type: GrantFiled: January 15, 1993Date of Patent: January 4, 1994Assignee: SARP IndustriesInventors: Jean-Louis Biros, Bertrand Gontard, Philippe Pichat
