The present invention relates to apparatus, methods, and applications for treating wastewater collection systems contaminated with fats, oils and grease (FOG), such as wet wells, transfer or lift stations, or main sewer lines, and more particularly to biological processes for removing the FOG from wastewater. This invention further relates to apparatus and methods for growing microbes on-site at a wastewater treatment facility or FOG-contaminated wastewater collection system location, and for economically inoculating sufficient microbes to solve various treatment problems rapidly.

Provided are dispersions which comprise more than about up to 55 percent by weight or more of an organic peroxide which is normally solid in an anhydrous liquid phase such as dibutyl maleate or dioctyl adipate, with about 5% by weight or more fumed silica to provide a thixotropic, storage stable organic peroxide paste. Addition of about 5 weight % or more of fumed silica was found to result in the formation of a shear thinning anhydrous dispersion of organic peroxide which was storage stable.

A one part, solids containing decontamination blend composition comprises a solid acetyl donor coated with a compound that protects it from hydrolysis, a peroxygen source, optionally a catalyst, optionally a surfactant, and optionally a buffer. The decontamination blend composition is generally in a dry powder, particle, etc form or in a tablet, pill, etc form and is complete in and of itself in that no additional compounds are required prior to use and is readily distributed as a one package system. Upon the addition of water, a peroxygen compound such as hydrogen peroxide is formed, and peracetic acid is generated under alkaline conditions. The decontamination blend composition is particularly suitable for oxidizing various chemical and biological compounds thereby eradicating the same in situ as on surfaces, clothes, articles, and the like. Representative contaminants include mustard gas, nerve gas, bacterial toxins, anthrax, bird flu, and the like.

Certain exemplary embodiments provide methods for reducing a concentration of a contaminant associated with a medium, which can be any substance or material, such as soil, water, air, and/or fluid. In one exemplary method, the medium is treated with a ferric chelate and an oxidizing agent in amounts effective to oxidize at least a portion of the contaminant.

A light source system that generates stable optical power over time and temperature in which a feedback control circuit is operative to receive a temperature signal and a sample signal and in response thereto generate a control signal to a driver circuit to maintain a power level of the light output substantially constant over an operative temperature range defined by T.sub.min and T.sub.max.

Methods and systems for on-site, continuous generation of peracid chemistry, namely peroxycarboxylic acids and peroxycarboxylic acid forming compositions, are disclosed. In particular, an adjustable biocide formulator or generator system is designed for on-site generation of peroxycarboxylic acids and peroxycarboxylic acid forming compositions from sugar esters. Methods of using the in situ generated peroxycarboxylic acids and peroxycarboxylic acid forming compositions are also disclosed.

An improved formulation may include an enhanced ability relative to its predicates to destroy toxic threats in the form of sporulated bacteria, bacteria protected by biofilms, planktonic bacteria, fungus, viruses, chemical weapons, toxic chemicals including Fentanyl, its analogs, and a whole host of toxic industrial chemicals. The formulation may include a three part product composed of a buffered detergent chemical system, a hydrogen peroxide chemical system and an accelerator system designed to deliver activated peroxygen species when blended together.

The invention includes a system and method for delivery and storage of an absorbent for solidification of liquid waste. The system includes a plurality of nestable containers configured to receive aqueous liquid to be solidified and forming a packet safe space when nested one within another. The system also includes a plurality of packets at least partially soluble in the aqueous liquid to be solidified. The containers include at least one packet and each packet contains a solidifier for use as an absorbent composition for the aqueous liquid to be solidified. A packet may be housed within the containers inside a packet safe space. The invention also includes an improved system and method for packaging a solidifier for solidification of liquid medical wastes.
