Abstract
This is a filter in which the water is caused to drip through the bulk filter material in such a way as not to flood it and thus encourage the exchange of oxygen between the air, the filtering material and the water. No stages of filling or drying are required, and it can operate continually as the filter material is partly dry and partly wetted by the water, which does not always follow the same path. <IMAGE>
