Frederick J. Kauppi - Newport Beach CA, US
James H. Welsh - Santa Ana CA, US
Stephen R. Lyon - Long Beach CA, US

International Classification:

C02F 3/32
C02F 3/04

US Classification:

210602, 210617, 210150

Abstract:

The present invention includes a portable Sub-Surface Flow Constructed Wetlands system for removing pollutants from a body of water. The portable wetlands system includes a sealed container having pipes for the inflow and outlet of the water. The system also includes a high surface area substrate located in a lower portion of the container and a heavier substrate and at least one emergent aquatic plant located in an upper portion of the container. The container of the system may be mounted on a trailer and the entire system may be light enough to be capable of being towed by a normal mid-sized pickup truck. The present invention also contemplates a method for removing pollutants from water using such a portable wetlands system. The water to be treated is flowed through the portable wetlands system in order to remove pollutants. The present invention further contemplates a method for constructing such a portable wetlands system.

Abstract:

The present invention includes a porous ceramic material for use in removing aqueous contaminants from water. The ceramic material is formed by drying particular types of clay-water mixtures from air dry to 600 C. The clay is then calcined at between 700 C. and 1175 C. Finally, the clay is processed to a size larger than colloidal. The present invention also includes a system for removing pollutants from water consisting of a container filled with the porous ceramic material. The container may be serially connected to other containers and may be disposed on a trailer for portability. The present invention further includes a method of removing pollutants from water consisting of directing the contaminated water though a system containing the porous ceramic material. The porous ceramic material may be regenerated for further use by directing an acidic solution over the porous ceramic material.
