I still strongly recommend keeping with the UF - it is the standard and will have significant advantages over conventional media systems. When was the last CIP? Borehole often has high Iron and can block a UF without much improvement from backwashing. Then a CEB is necessary with Acid or if it is severe then a CIP with citric acid is highly recommended. I had a plant that hit 2.0 bar TMP from metals. 1 CIP and the TMP was back at 0.4 bar. Dow UF fibres are very chemically resistant so cleaning procedures can be harsh without long term damage to the fibres.
