Title (EN) A METHOD AND AN AGENT FOR CHEMICAL PURIFICATION OF WATER BY MEANS OF CHEMICAL PRECIPITATION AND MAGNETIC SLUDGE SEPARATION
(FR) METHODE ET AGENT DE PURIFICATION CHIMIQUE DE L"EAU PAR PRECIPITATION CHIMIQUE ET SEPARATION MAGNETIQUE DE LA BOUE
Abstract: front page image
(EN)A method and an agent for chemical purification of water is provided, especially waste water with subsequent magnetic sludge separation. A precipitation agent comprising as component aluminium sulphate and/or iron sulphate is used together with a magnetic material for the purification. In order to provide uniform distribution of the magnetic material in the agent composition it is added to the aluminium and/or iron sulphate component of the composition when said component is in the form of a melt or solution prior to crystallization of said composition.
(FR)Une methode et un agent de purification chimique de l"eau, specialement des eaux residuaires, avec separation magnetique ulterieure de la boue. Un agent de precipitation comprenant, en tant que composant, du sulfate d"aluminium et/ou du sulfate de fer est melange a un materiau magnetique pour effectuer la purification. Pour assurer une repartition uniforme du materiau magnetique dans la composition de l"agent, on ajoute du sulfate d"aluminium et/ou de fer lorsque ledit composant se trouve a l"etat de fusion ou de solution avant que n"ait lieu la cristallisation de ladite composition.
