Patents

The E.M. Hydropure treatment process is covered by granted and pending patents in the United States and abroad. Our patent position protects the treatment method itself, the sequence and chemistry by which contaminants are coagulated, flocculated, and separated from wastewater along with the fertilizer co-product recovered from the resulting solids.

U.S. Patent No. 12,729,144 B2

Systems, Methods, and Compounds for Sustainable Wastewater Treatment and Co-Products Thereof

Issued: September 8, 2026

Inventor: Michael P. Eaton

Application 17/735,693, filed May 3, 2022, with priority to May 5, 2021

21 claims

What the patent covers

The patent claims a sequential wastewater treatment method in which:An acid is introduced to lower the pH of the wastewater. A first compound combining diatomaceous earth, bentonite, and chitin or chitosan is then introduced as filtering medium, coagulant, and flocculant, and the mixture is aerated. A second compound tempered charcoal with a pH-raising agent follows, adsorbing contaminants, disinfecting, and restoring pH balance through a second aeration stage. The wastewater is then held for a flocculation period, separating into reusable treated water and a de-waterable sludge byproduct.

Further claims cover the processing of that sludge byproduct into a nitrogen-bearing fertilizer co-product, including dewatering, blending, and pelletizing.

The process uses no membranes, no ion-exchange resins, and no synthetic polymers. Patent protection runs into 2045.

Pending Applications

Additional patent applications remain pending internationally.

Independent Verification

A granted patent establishes that our process is novel. Our performance data is verified separately by GEL Laboratories, LLC (ISO 17025, NELAP accredited).
