A method of suspending elemental sulfur in water includes the steps of providing water including elemental sulfur and hydrogen sulfide and adding from about 1 to about 100 parts by weight of a sulfur suspension additive to the water based on one million parts by weight of the water to suspend the elemental sulfur in the water. The sulfur suspension additive is chosen from an alkyldiphenyloxide disulfonate or salt thereof, a secondary alcohol ethoxylate, a non-ionic ethylene oxide and/or propylene oxide copolymer, and combinations thereof.

Method of suspending elemental sulfur in water

A method of controlling and removing biofilm on a surface in contact with an aqueous industrial system comprising the step of adding an effective amount of biofilm-disrupting agent and adding a biocide to the aqueous system being treated to reduce and remove biofilm forming microbes from a surface in contact with the aqueous system is disclosed. Also disclosed is a synergistic composition of polyethyleneimine and an oxidizing biocide.

Compositions exhibiting synergy in biofilm control

The present invention provides a method of controlling bacterial contamination using synergistic interactions of antimicrobials. The invention consists of combinations of chlorine dioxide and organic acid whose combined antimicrobial effect is greater than the sum of their individual activities, i.e., synergistic.

Synergistic blends of antimicrobials useful for controlling microorganisms in industrial processes

An antimicrobial composition comprises at least one or more organic acid or salt in water, one or more antimicrobial agent which has limited water-solubility. The composition contains high active content and is stable for long period of time.

Organic acid antimicrobial compositions

The present invention provides a method of controlling bacterial contamination using synergistic interactions of antimicrobials. The invention utilizes a combination of organic acids where the combined antimicrobial effect is synergistic.

Synergistic combinations of organic acid useful for controlling microoganisms in industrial processes

A method of reducing undesirable microorganism concentration, the method comprises (a) introducing a quantity of fermentable carbohydrate, sugar or cellulose to an aqueous system, (b) introducing a quantity of desirable microorganism to the aqueous system, (c) introducing a hops acid extract into the aqueous system and (d) introducing an organic acid solution into said system.
