<p>A water treatment system is described, for use with potent wastewaters such as septic tank effluent, the system including single-pass aerobic filtration in a small contained transportable volume, using a special water-absorbent and air-permeable filter medium such as polyurethane foam particles, and including optional ensuing water-saturated treatment for removal of additional undesirable constituents before discharging to the environment. The high-rate aerobic biofilter has low maintenance requirements, is independent of soil and drainage conditions, and can be pre-manufactured for predictable performance.</p> |
