Title (EN) MEANS AND PROCESS FOR NITRATE REMOVAL
(FR) MOYENS ET PROCEDE D'ELIMINATION DES NITRATES
Abstract: front page image
(EN)A system for nitrate removal from aquariums, both fresh water and marine aquariums, by means of permeable polymeric beads which contain a combination of fermentative and denitrifying bacteria and a carbon source. Preferred beads are beads made from sodium alginate or chitosan. The bacteria, in the presence of the carbon source, are able to reduce nitrate to nitrogen gas. Bacteria which are not harmful to fish are used. The porous beads used in the process are novel and part of the invention.
(FR)Système d'élimination des nitrates présents dans des aquariums, tant d'eau douce que d'eau salée, par l'intermédiaire de perles polymères perméables qui contiennent une association de bactéries dénitrifiantes et fermentatives et une source de carbone. Les perles utilisées de préférence sont celles composées d'alginate de sodium ou de chitosane. Les bactéries, en présence de la source de carbone, réduisent les nitrates en azote. Des bactéries non nocives pour les poissons sont utilisées. Les perles poreuses utilisées selon ce procédé sont nouvelles et font partie de l'invention.
