A flocculation control system that floats particles that attach to nano and/or micro bubbles out of a liquid includes at least one sensing system, at least one processing system, and at least one fluid additive control system. The at least one sensing system is configured to reproduce one or more nano-bubbles with one or more particles suspended in a fluid. The at least one processing system is configured to measure, using outputs of the at least one sensing system, incident angles between the one or more nano-bubbles and the one or more particles suspended in the fluid. And the at least one fluid additive control system is configured to adjust, based on at least the incident angles, an amount of a surfactant being added to the fluid.

Provided are nanonets comprising a) a surfactant aggregate having an average aggregate diameter; and b) a polymer having an average particle diameter which average particle diameter is the same or smaller than the average aggregate diameter, wherein the nanonet has a diameter larger than the average particle diameter. Also provided are kits therefor and methods for sequestering non-water moieties from aqueous solutions using nanonets.

Provided are sequestering agents for sequestering non-water moieties from an aqueous solution. The sequestering agents may comprise a detergent; and a polymer operable to stabilize formation of a detergent micelle thereby causing the detergent and polymer to self-assemble into a nanonet upon exposure to the aqueous solution. Also provided are kits therefore and methods for use of the sequestering agents and kits.

The subject invention provides compositions for treating standing water, such as retention ponds and puddles, as well as soils prone to flooding and pooling. More specifically, the subject invention provides microbe-derived compositions as well as their use in preventing and/or mitigating, i.e., draining, undesirable standing water and/or problems associated with standing water, such as mosquitos and algal growth. Advantageously, the compositions and methods of the subject invention can be used as environmentally friendly, non-toxic and cost-effective solutions for water-use efficiency, soil health, and pest control.

In a process for separating a solid material from a suspension of the solid material in water, an organopolysiloxane polyalkylene oxide copolymer comprising a branched organopolysiloxane structure is added to the suspension of solid material in water and the suspension is drained. The organopolysiloxane polyalkylene oxide copolymer comprising a branched organopolysiloxane structure increases the rate of drainage of the suspension.

A surfactant composition in aqueous phase includes 0.5% to 15% by weight of an alkoxylated block copolymer and 0.5% to 15% by weight of an alcohol ethoxylate. The non-ionic alkyl ethoxylate is a fast wetting agent. The block copolymer, which is characterized by a longer wetting time than the non-ionic alkyl ethoxylate, disrupts the emulsion and allows the now-coated sulfur particles to escape the existing emulsion. The composition may also include an alkyl alcohol and/or glycol ether. The alkyl alcohol augments the emulsion-breaking capabilities of the diblock copolymer by providing additional surface tension reduction to the system, as well as emulsion inhibition at the aqueous-gaseous interface. The glycol ether acts as a mutual solvent, which also augments the emulsion breaking capabilities of the diblock copolymer by providing additional surface tension reduction to the system, as well as emulsion inhibition at the aqueous-gaseous interface.

A method may introduce a surfactant to the sour gas stream, the surfactant including an alkoxylated block copolymer and a glycol ether. A method may introducing, to the sour gas stream, a reducing reagent configured to convert the sulfur species in the sour gas stream into at least one of solid sulfur or solid sulfur species.

The present invention provides improved methods for purifying and/or removing multiply charged cations and suspended solids from water. In particular the process relates to an additive composition that has the appropriate surfactant characteristics for effectively removing multiply charged cations and suspended solids from an aqueous or oil/aqueous mixed phase via foam fractionation. According to the invention, a hydrophobically modified polymer that acts as an associative thickener is used in the presence of a source of alkalinity or anionic reactant as well as surfactant in appropriate ratios to facilitate multiply charged cation and suspended solids removal for water purification in any of a number of commercial, environmental and industrial applications.
