Amiad’s Filtomat Microfibre pre-treatment technology ensures efficient and reliable nanofiltration of Scottish Highland loch water
In this feature article we report on the effectiveness of Amiad’s Filtomat Microfibre automatic self cleaning filter technology as a pre-treatment for membrane systems. We focus on high and variable suspended solids and colour removal applications where potable quality water is required from nanofiltration (NF) systems. We show how the Filtomat Microfibre units provide effective pre-filtration of Scottish Highland loch water and examine how the technology operates, and how it can be integrated into an overall membrane-based solution. We include details on a project installed at Scottish Water’s Mallaig Water Treatment Works (WTW), UK, in 2001, and evaluate the effectiveness of the Filtomat Microfibre units operating on-site. We draw on Scottish Water’s operational experiences since the commissioning of their NF plant.
