If the antiscalant is not correctly dosed at the appropriate concentration, then this can lead to severe scale deposition on the RO membrane leading to significant loss of production of product water. Recently a new antiscalant has been introduced based on chemical composition, biodegredation and ...
This result is correlated with the phosphonate based antiscalant composition. Therefore, antiscalant selection and dosage appear to be critical for membrane fouling development.Soumaya FarhatFethi KamelYounes JedouiDesalination: The International Journal on the Science and Technology of Desalting and Water ...
It was fed from a groundwater well having cartridge filters and antiscalant dosing as a pre-treatment. It is a two stages desalination plant with the BW30-400 membrane element. Chemical and structural characterization was performed by visual inspection, qualitative analysis test and by scanning ...
There are various approaches to membrane scale mitigation including, for example, removal of scale precursor ions via feedwater pretreatment (e.g., chemical softening, ion exchange, nanofiltration), and inhibition of nucleation/crystal growth via dosing of antiscalant into the RO feedwater [10].
