Hello Tendai, there seem to be several approaches, for me remains still the question how much water you want to treat. If there is a only a minor volume per day (e.g. 100 liters), an simple ultrafiltration filter can solve the issue here. We from Kwatee have used in similar cases a simple filter (combination of ultrafiltration or microfiltration with activated carbon) that can treat 5000 liters of water and costs only 80 EUR. It is a standard 10" filter, the housing is available all over the world (e.g. "the blue filters").
