IWE FL2 Membrane Compatible Flocculant
[su_note note_color=”#e5f2ff” radius=”10″]To minimise membrane fouling and reduce cleaning frequency the silt density index (SDI) should be kept as low as possible. IWE FL2 can be used to improve the performance of filtration equipment and has been developed as a general-purpose flocculant for use in surface, well and process waters with medium to high SDI values. IWE FL2 is compatible with polyamide membranes and does not foul membranes like conventional iron and aluminium based coagulants.

Application
IWE FL2 should be dosed continuously to the feed water allowing at least 5 minutes contact time before filtration. Dose rate can be optimised by on site jar testing and SDI analysis. Typical dose rate of IWE FL2 is 1- 4 mg/L. IWE FL2 can be diluted and is fully miscible with water in all proportions.
Health and Safety
IWE FL2 is an aqueous solution of a polyquaternary amine. It is compatible with carbon steel and other commonly used materials of construction. Observe all safety precautions shown in the material safety data sheet, available on request.
