Abstract: A process for separating clean water which has an impurities content of less than 100 ppm from waste materials such as farm manure is disclosed. In a first step, a plate separator splits the waste material stream into a first effluent fraction and a first solids fraction. The first solids fraction then undergoes two stages of pressing to increase the solids contents to about 30 to 40 percent which makes it suitable for granulation or pelletizing. The first effluent fraction is treated in successive stages with various chemical agents resulting in the removal of most of the solids and inorganic impurities from the effluent to achieve drinkable water purity.

Abstract: Improved sparge compositions for reverse froth flotation separation and uses thereof, and methods of reverse froth flotation are described. The sparge compositions comprise sulfonated polymeric modifiers which can act as dispersants and depressants, and the compositions are suitably used in the reverse froth flotation of particulate material containing ultrafine particles. For example, the compositions and methods can be used in the separation of phosphate beneficiary from ores comprising phosphates, dolomite, calcite, clay, silica, silicates, carbonates, and mixtures thereof.

The sparge compositions comprise sulfonated polymeric modifiers which can act as dispersants and depressants, and the compositions are suitably used in the reverse froth flotation of particulate material containing ultrafine particles.
