A process for the manufacture of an aqueous composition that is a combination of a fungicide and fertilizer comprising the following steps: The reaction product prepared according to the above process can also be used as a bactericide.

Acid combination one step reaction process for agricultural use products and associated methods

A process for the manufacture of an aqueous composition that is a combination of a fungicide and fertilizer comprising the following steps: Using a similar process a composition having fungicidal properties is prepared by reaction phosphoric acid with potassium hydroxide. The reaction mixtures prepared according to each of the above processes are also part of this invention.

A process for the partial purification of contaminated phosphoric acid plant pond water is described, in which the pond water is treated sequentially, with two basic compounds, clarified, aged, clarified again and re-acidified. The thus treated pond water, still containing the majority of the phosphate originally present, can then be concentrated via the removal of essentially pure water, using any conventional means of concentration, without the formation of solid precipitates.

Purification of phosphoric acid plant pond water

A simplified process for the partial purification of contaminated phosphoric acid plant pond water having a molar calcium plus magnesium to fluorine ratio greater than or equal to about 0.60, is described, in which the pond water is treated with a basic compound, clarified, aged, clarified again and re-acidified. The thus treated pond water, still containing the majority of the phosphate originally present, can then be concentrated via the removal of essentially pure water, using any conventional means of concentration, without the formation of solid precipitates.
