(Main)Chemicals used for treatment of water intended for human consumption - Antifouling for membranes – Sulfamic acid
Chemicals used for treatment of water intended for human consumption - Antifouling for membranes – Sulfamic acid
This European Standard specifies the characteristics and the requirements for sulfamic acids and salts.
Similar to antiscalants as phosphonic acids and its salts (EN 15040) and polycarboxylates and its salts (EN 15039), sulfamic acid and its salts can be used alone or in combination with others drinking water substances as antifoulants (antiscalant effect) for membranes for the treatment of water intended for human consumption.
Sulfamic acid and salts are used in mixtures with sodium hydroxide and sodium hypochlorite or other drinking water chlorine based oxidizing agents as biofilm remover especially for reverse osmosis (RO) and nanofiltration membranes to prevent biofouling by microbiological contamination. The components will not pass the membrane and are rejected to the wastewater with the concentrate. For the other components EN standards are already exist.
Produkte zur Aufbereitung von Wasser für den menschlichen Gebrauch - Antifouling für Membranen - Amidosulfonsäure und -salze
Dieses Dokument gilt für Amidosulfonsäure, die als Antifoulingmittel für Membranen bei der Aufbereitung von Wasser für den menschlichen Gebrauch verwendet wird. Es beschreibt die Eigenschaften von Amidosul
fonsäure und legt die Anforderungen und die entsprechenden Prüfverfahren für Amidosulfonsäure fest. Es enthält Angaben zu deren Anwendung als Antifoulingmittel für Membranen bei der Wasseraufbereitung.
Produit chimique utilisé pour le traitement de l’eau destinée à la consommation humaine - Produit antitartre pour membranes - Acide sulfamique
Le présent document est applicable à l’acide sulfamique utilisé comme produit antitartre pour membranes dans le traitement de l’eau destinée à la consommation humaine. Il décrit les caractéristiques de l’acide sulfamique et spécifie les exigences et les méthodes analytiques correspondantes. Il donne des informations pour leur emploi en tant que produit antitartre pour membranes dans le traitement de l’eau.
Kemikalije, ki se uporabljajo za pripravo pitne vode - Proti obraščanju membran - Sulfamska kislina
Ta evropski standard določa lastnosti in zahteve za sulfamske kisline in soli.
Podobno kot sredstva proti apnencu (npr. fosfonske kisline in njene soli (EN 15040) ter polikarboksilne kisline in njene soli (EN 15039)) je mogoče sulfamsko kislino in njene soli uporabljati samostojno ali v kombinaciji z drugimi snovmi za pitno vodo kot sredstva proti obraščanju (učinek sredstva proti apnencu) membran za pripravo pitne vode.
Sulfamska kislina in njene soli se uporabljajo v mešanicah z natrijevim hidroksidom in natrijevim hipokloritom ali drugimi oksidanti na osnovi klora za pitno vodo kot odstranjevalec biofilma, zlasti na membranah za povratno osmozo (RO) in nanofiltracijo, s čimer se prepreči biološko obraščanje organizmov zaradi mikrobiološke kontaminacije. Komponente ne prehajajo skozi membrano in se skupaj s koncentratom izločijo v odpadno vodo. Za ostale komponente že obstajajo standardi EU.
