Wavy agricultural tillage blade with sharpened edge

A method of making a tillage blade by obtaining a generally circular sheet metal steel disc having an outer peripheral edge. Waves are made in the outer peripheral edge of a circular steel disc in a predetermined pattern while the steel is cold. The outer peripheral edge is then sharpened at a predetermined acute angle with respect to a first plane by grinding. Then the disc is heat treated to make it harder so it will wear longer. If it is desired to have a concave/convex disc, instead of a coulter, then during the heat treating process the disc is deformed so that the sharpened portions of the peripheral edge remain generally in the first plane but a central portion of the disc is disposed at least partially in a second plane which is parallel to but spaced from the first plane.

Contact bridge with blow magnets

The present invention relates to contactors for unidirectional DC operation with permanent magnetic arc extinguishing.

Method and system for treating wastewater and sludges by optimizing sCO2 for anaerobic autotrophic microbes

The present invention describes a method of optimizing CO2 concentration to increase the specific growth rate of Anammox bacteria and methanogens in wastewater and sludge treatment, as well as novel systems and methods of treating wastewater and sludge. The specific growth rate or doubling time of the Anammox bacteria and methanogens were determined to be sensitive to dissolved CO2 concentration. Optimizing dissolved CO2 concentration increases the specific growth rate of the Anammox bacteria, which may be used as an alternative biological nitrogen removal process for the treatment of domestic wastewater. In the method and system of treating sludge, the CO2 stripper returns biogas with low CO2 concentration to the headspace of an anaerobic digester in order to lower the headspace CO2 concentration and therefore, the soluble CO2 concentration. The lower soluble CO2 concentration increases the specific growth rate of the methanogens for a more efficient anaerobic digestion process.
