membrana a spirale per acqua
Membrane acqua primaria
La membrana a spirale avvolta di osmosi inversa (spiral wound RO membrane) risulta particolarmente adatta ad essere impiegati per la rimozione dei solidi disciolti in acqua di diversa natura: tap water, fresh water, brackish water, saline water, sea water and brine water.
L’unità fondamentale è costituta da un sandwich di strati di membrana in PA sotto forma di fogli avvolti intorno ad un tubo forato; ciascuno si compone di due superfici di membrana affiancate sul lato posteriore e separate da uno spessore destinato all’allontanamento del permeato. Gli strati risultano sigillati su tre lati mentre il quarto è collegato al tubo del permeato.
Le membrane per acqua di dividono nelle seguenti macroaree:
- Brackish water BWRO 2,5"x40”; 4”x40”; 8”x40”
- Brackish water Low Energy BWRO LE RO 2540; 4040; 8040, 1812
- Seawater SWRO/High rejection 2,5"x40”; 4”x40”; 8”x40”
- Tapwater RO (Drinking water)
- Tap water Low Energy/Energy Saving RO (Drinking water and beverage)
- Extra Low Energy and Ultra Low Pressure RO elements
Forte di una collaborazione ormai trentennale con Osmonics, Desal, GE Water, ora Suez, Sepra è in grado di fornire membrane per ogni tipologia di applicazione e proponendo alternative a tutti i prodotti presenti sul mercato. Recentemente la gamma Suez è stata ampliata con l'acquisizione della linea di prodotto Lewabrane dal gruppo Lanxess. I produttori e marchi principali di membrane a spirale avvolta per acqua sono: Filmtec DuPont, Hydranautics, Toray, CSM, Ropur, Vontron, Pentair, Mann+Hummel, Microdyn Nadir, Trisep, Oltremare, LG RO.
