A method can include providing at a location remote from a tank of a pre-existing separation facility an induced gas separation unit including a pump and an eductor, then transporting the induced gas separation unit to the separation facility, then connecting the induced gas separation unit to the tank, and then operating the induced gas separation unit, thereby pumping gas into a fluid composition in the tank. A system can include an induced gas separation unit with a pump and an eductor mounted to a portable structure, a line providing fluid communication between a pump inlet and the fluid composition in at least one tank, a line providing fluid communication between the eductor and a gas in the tank, and a third line providing fluid communication between an eductor outlet and the fluid composition in the tank.

An ultrafine bubble cleaning apparatus uses a liquid containing ultrafine bubbles having a size of less than 30 nm to rinse fine particles adhered to soil, sand, etc. to separate and collect the fine particles. The ultrafine bubble cleaning apparatus includes a water tank-shaped reservoir, a stirring device, a supernatant discharge device including a pump for discharging a supernatant of the liquid in the reservoir, and a sedimentation extraction device. Substances are loaded into the ultrafine bubble-containing liquid stored in the reservoir, and the ultrafine bubble-containing liquid is repeatedly brought into contact with the surface of the substance using the stirring device. When ultrafine bubbles get into a space between fine metal particles adhered to the surfaces, cracks, and pits of the substances to be cleaned (including metal ions) and fine particles of organic substances including a solvent, a chemical, and oil, the fine particles are separated and floated.

Cationic reverse flotation methods, systems, and processes for producing a marketable iron oxide concentrate from an iron oxide mineral slurry (treatment slurry), wherein the iron oxide content of the concentrate is greater than the iron oxide content of the treatment slurry, include introducing the treatment slurry into a flotation cell, together with a collector, a frother and optionally an iron oxide depressant, and recovering two flow streams from the flotation cell, namely a froth fraction (also referred to as a flotation tail fraction) and a sink material fraction (also referred to as the flotation concentrate), wherein the treatment slurry in the flotation cell is maintained at a Natural pH.

A modular system for reducing the total suspended solids of waste, including scum, sludge and water layers, includes a plurality of chambers each being connected in succession by a corresponding one of a plurality of flow pipe segments including an inlet segment, an outlet segment and at least one middle segment, wherein the waste enters the septic tank via the inlet segment and is transferred between each of the plurality of chambers via the at least one middle segment; a corrugated flow pipe in fluid flow communication with the outlet segment; and the corrugated flow pipe being sized and configured for use as a settling zone for removal of a portion of the total suspended solids and wherein an amount of water from the water layer within the chamber adjacent the outlet segment enters the corrugated flow pipe and passes through the outlet segment.
