In early spring we installed a filter at the office. Now it has been sitting there for about four months and as you can see in the film, the cloth is quite dirty. The cloth is there for two reasons. To steer the incoming water towards the center of the filter and to absorb oils. We are planning on leaving this filter in the drain for a year, then remove it and analyze the absorbents to see what pollutants have been absorbed.
