  • Patent number: 6093287
    Abstract: A magnetic processing treatment facility is disclosed for subjecting a fluid flow to magnetic energy. The facility is integrated into agricultural spray apparatus and is effective in increasing the water solubility of chemical agents such as herbicides, pesticides, fertilizer, nutrient liquids and other liquids for agricultural use that are dispersed as a spray solution over an application area. The magnetically treated chemical solution also exhibits enhanced activity in terms of crop growth and pesticide and weed control. The treatment facility utilizes a magnetic core device having a resident permanent magnet for generating a magnetic field that is applied to a fluid volume passing through the device.

  • Patent number: 5587060
    Abstract: Disclosed herein is a technique of removing metal contained in a solution through chelation, which makes it possible to preclude undesired aggregation and permit effective aggregation through an aggregating process. A surface active agent containing a hydrophobic group, a hydrophilic group and a chelating group is added to the solution to be processed, and subsequently an aggregating process is carried out. The chelating group chelates metal, the hydrophilic group prevents undesired aggregation, and the hydrophobic group is effectively aggregated in the aggregating process. Various uses are possible by selecting the charge of ligand.
