An antifoam granule includes a carrier and an antifoam compound deposited on the carrier. The antifoam granule is formed using a method that includes providing an emulsion and contacting the emulsion with a carrier to deposit the antifoam compound on the carrier and form the antifoam granule. The emulsion includes an oil phase, an aqueous phase, and a silicone polyether. The oil phase includes an antifoam compound. The antifoam compound includes a hydrophobic fluid and a hydrophobic filler dispersed in the hydrophobic fluid. The aqueous phase includes a binder and water. The emulsion is formed using a method that includes combining the oil phase, the aqueous phase, and the silicone polyether to form the emulsion. The antifoam granule is also utilized in a method of facilitating rinsing of a detergent from a substrate that includes applying the detergent, including the antifoam granule, to the substrate and rinsing the substrate.

Defoamer preparations contain a polyorganosiloxane having aryl groups bonded to silicon at a ring carbon, filler particles and/or silicone resin particles, and a polyoxyalkylene polyether containing oxypropylene moieties. In addition to being efficient and compatible, the defoamer compositions retain their efficiency, especially in liquid detergents, after storage.

A wet process phosphoric acid production method comprises digesting phosphate-containing ore in a slurry comprising sulfuric acid, whereby phosphoric acid and calcium sulfate crystals are formed; and separating the phosphoric acid from the calcium sulfate crystals; wherein a defoamer and a poly(carboxylic acid), or salt thereof, having a weight-average molecular weight of less than 1,000,000 grams per mole (g/mol), are added to the slurry. The poly(carboxylic acid) can be a poly(acrylic acid), or salt thereof, and the defoamer can be a dialkyl sulfosuccinate salt and an aliphatic alcohol or a fatty acid ester. The method enhances separation of phosphoric acid from calcium sulfate crystals in wet process phosphoric acid production by any one of increasing the volume average particle size of the calcium sulfate crystals, increasing filtration rate, and reducing foam formation.

Cyclic ketal compounds provide excellent foam protection when having at least one moiety of a threshold size (comprising 4 or more carbon atoms) pendant from a ketal carbon. The carbons in such moieties may be present in one or more chains. The cyclic ketal compounds of the present invention are compatible with foodstuff manufacturing. In particular, it has been discovered that the cyclic ketal compounds of the present invention exhibit excellent foam control performance in both potato and sugar beet processing systems.

A non-silicon defoaming agent, includes an acrylate polymer, an organic solvent carrier, hydrophobic particles and defoaming auxiliaries; and the acrylate polymer is prepared from following raw material components: monomer-1, monomer-2, unsaturated terminated polyether, alkene, diluent and initiator. The present invention further includes a preparing method for the non-silicon defoaming agent and the application of the non-silicon defoaming agent to the defoaming and foam inhibiting in systems rich in anionic surfactants. The defoaming agent takes the acrylate polymer as the main active substance and has excellent defoaming and foam inhibiting performance. By dropwise adding monomers, the defoaming performance of the acrylate polymer is improved, by using unsaturated terminated polyether to modify, the hydrophilia of the acrylate polymer is improved, the instant defoaming capacity is further improved, and by the alkene with the carbon atoms of 6-22 to modify, the foam inhibiting performance of the defoaming agent is improved.

The present invention provides improved methods for purifying and/or removing oily particles, and/or contaminants suspended or dissolved in water. In particular the process relates to an additive composition that has the appropriate surfactant characteristics for effectively removing an oil phase from an oil/aqueous mixed phase via foam fractionation. According to the invention, a hydrophobically modified polymer that acts as an associative thickener is combined with surfactant in appropriate ratios to facilitate oil removal for water purification in any of a number of commercial, environmental and industrial applications.

Rapid and long lasting defoaming is accomplished by use of a defoamer formulation employing an organopolysiloxane having siloxy groups linked by an alkylene group, a filler, a silicone resin, a silanol-terminated organopolysiloxane, and an inorganic or organic acid.
