The present disclosure provides a movable device and system for the application of pressurized fluid, collection of that fluid, and cleaning and recycling of that fluid for subsequent use. An application of the current device is in the washing of items, for example, automobiles.

Described herein are methods for transporting and/or harvesting gas from bubbles, as well as associated articles and systems. In some embodiments, transporting and/or harvesting the gas from the bubbles can reduce or prevent the amount of foam that is present within a system. According to certain embodiments, a conduit comprising a porous wall portion can be at least partially submerged into a foam and/or a bubble-containing liquid. The porous wall portion of the conduit can be configured and/or arranged, according to certain embodiments, such that the porous wall portion provides a fluidic pathway through which gas from the bubbles within the liquid may be channeled to a gaseous environment in the interior portion of the conduit. The gas may be transported, according to certain embodiments, along the interior portion of the conduit into an external gaseous environment and/or harvested from the interior portion of the conduit.

The present invention relates to a stabilized water treatment composition, containing (i) an effective amount of a hydrogen peroxide source, (ii) a first stabilizing agent, and (iii) a second stabilizing agent; which is essentially free of any peracid-based compounds, derivatives or salts thereof. A method for the using the stabilized water treatment composition to kill or to inhibit the growth of microorganisms such as gram positive or gram negative bacteria, algae, cyanobacteria, viruses, fungi, mildew, mold or combinations thereof, for various water sources such as streams, ponds, lakes, recirculating water systems, surface water, and any other suitable or desirable water sources is also described.

This invention refers to a method for preparing a chemical digester characterized by using organic and inorganic elements used for multiple purposes such as an accelerator in the decomposition of organic matter, as a water flocculant, as an organic soil fertilizer and as a means to eliminate the concentration of flies and other inserts in organic matter to decompose. The method comprises heating water in a reactor at a temperature of 38 C., adding a polysaccharide, an anti-thickener and an antifoam. The method then comprises the addition of two organic acids, one of them previously mixed in a second reactor and, finally, an inorganic acid until the mixture is homogenized. Optionally the method comprises the packaging of the mixture and the treatment of organic matter.

The present invention relates to apparatus, methods, and applications for treating wastewater, and more particularly to biological processes for removing pollutants from wastewater. This invention further relates to apparatus and methods for growing microbes on-site at a wastewater treatment facility, and for economically inoculating sufficient microbes to solve various treatment problems rapidly.

A method of spray evaporating water while limiting emission of particles regulated as pollutants is also disclosed.

A produced water evaporation system for spray evaporating water comprising a geothermal heat retainment system and an evaporation system is disclosed. The geothermal heat retainment system comprises a first feed inlet, an optional solar collection system or a heat exchanger, and a first discharge outlet. The evaporation system comprises a second feed inlet, a pump, a drip manifold comprising a drip orifice or a manifold comprising a nozzle, a container, wherein a first portion of a ceiling of the container is constituted by a demister element such that the first portion of the ceiling is entirely configured as an outlet for evaporated water and wherein a second portion of the ceiling is adjacent to an upper edge of a wall of the container, a second discharge outlet, and an air system comprising an air blower and an optional air preheater, wherein the air system is disposed through the wall of the container and wherein the air system discharges air flow counter to the produced water and/or water droplets from the drip orifice. A method of using the produced water evaporation system is also disclosed.

In some embodiments, a fluid separation system is provided. The system includes a reactor for coagulating one or more suspended fluids in a fluid solution. The system also includes a first filtration unit downstream of the reactor for removing a first portion of the coagulated solids. The system also includes a second filtration unit downstream of the first filtration unit for removing a second portion of the solids.

A process of treatment of carbonaceous material, such as wastewater sludge or organic waste, includes performing a thermal treatment of the carbonaceous material, thereby providing thermally treated carbonaceous material, cooling the thermally treated carbonaceous material, thereby providing cooled carbonaceous material, the cooling being performed using a vacuum cooling procedure, and performing a post-treatment of the cooled carbonaceous material, and at least one carbonaceous material degassing.
