To prevent clogging the membranes, a pre-filtration system can remove particles of sand and organic matter down to 1 micron in size. Install a back-washed sand filter at the inlet. Use a series of filters (e.g., 50-25-5-1 micron) to remove other particles. If you put the finer filter first, it will clog immediately. Install an oil-water separator to remove oil. An absorption/reactive carbon filter will remove taste, odour, chlorine and organic chemicals.

Right sizing the [[ElectricalSystem|electrical system]], [[HeatingCalculation|heating]], [[VentilationCalculation|air conditioning]], [[WaterCapacity|water capacity]] and related watermaker are the most critical lifestyle decisions you will have to make. Getting it wrong will lead to deeply felt dissatisfaction, and costly retrofitting. Yet getting it right is very difficult. You won’t know whether it’s right until you start living the experience. And sizing the water-maker is more difficult than the HVAC. Any system you select should have automatic TDS (total dissolved solids) testing and automatic flush and back-wash.
