A method and system for collecting objects floating on or suspended near a surface of water. A collecting system is employed comprising a floating barrier. The collecting system is unanchored to or on the seabed such that the collecting system is free to move along the surface of the water. A submerged portion and non-submerged portion is provided connected to the floating barrier, such that a velocity of the floating barrier along the surface of the water differs from a surface velocity of the water at the location of the floating barrier. Collected plastic objects can be recycled. Further, the ocean currents are followed while being able to collect plastic.

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.

A thin film, direct convection, evaporative process and apparatus for treating waste water on-site at a production area or waste water processing area relies on direct exposure of waste water to an open flame in an evaporation chamber, despite the waste water containing volatile substances, resulting in up to 99% reduction of total flow rate of waste water, and creating steam capable of being introduced safely to the environment.

A portable and modular renewable energy microgeneration apparatus is disclosed that includes at least four modular units. The first modular unit includes a mixing tank and a chopper. The second modular unit includes a buffer tank, a liquor tank, and a pasteurization tank that pasteurizes waste that has been mixed with liquid from the liquor tank by the mixer, chopped into smaller sized components by the chopper, and pre-warmed by the buffer tank. The third modular unit includes a digestion tank that performs anaerobic digestion on pasteurized waste received from the pasteurization tank. And the fourth modular unit includes a gas storage tank that stores gas generated by the waste in at least one of the mixing tank, the chopper, the buffer tank, the liquor tank, the pasteurization tank, and the digestion tank. Each of the four modular units is both portable and modular.

Systems and methods can support an autonomous pool skimming system. The pool skimming system may have a body with two or more hulls. Two or more paddlewheels may be coupled to the body. An independent motor may drive each paddlewheel. The motors may be independently controllable to support steering. The pool skimming system may have one or more processing units, two or more distance sensors, one or more solar cells, and a power supply operable to power the processing units and the motors from energy supplied by the solar cells. One or more processing modules may configure the processing units to plan and execute a traversal path across the surface of a body of water, such as a swimming pool, to collect debris into a removable basket. A portion of the traversal path may be established according to signals from distance sensors.

The cooling device for a power source for a ship propulsion device that pumps up cooling water, from which foreign matters with sizes that cause clogging of a cooling water route have been removed, supplies the cooling water to a cooling water passage (30), and discharges the cooling water to outside after cooling a power source (10) includes: a cartridge-type filtration device (40, 73) that is provided at a midpoint of a first water passage (36, 71) in the cooling water route and incorporates a filter (45, 46) for filtrating foreign matters remaining in the cooling water; and a second water passage (38, 72) that is branched from the first water passage and adapted such that a valve member (53) is opened to cause the cooling water to flow in a case in which clogging occurs in the filter.

A method and system of wastewater evaporation uses a turbine-based wastewater evaporation system to convert wastewater to steam. The wastewater evaporation system includes a wastewater heating track disposed in the interior of the exhaust collector of the turbine in the flow path of turbine exhaust. The wastewater fluidly communicated therethrough is heated by the turbine exhaust and fluidly communicated to a plurality of atomization nozzles. The plurality of atomization nozzles direct atomized wastewater into the interior of the exhaust port of the turbine that is converted to steam in the presence of turbine exhaust within the exhaust port. The system may be disposed on a mobile trailer or skid to facilitate disposing the system on a job site and may be remotely controllable by a remote operator.

A transportable system for creating an oxidation reduction potential (ORP) in water employs a pipe assembly for in-line mixing. The pipe assembly includes a first flow path for water to flow through. The first flow path includes one or more ozone intake ports that are fluidically coupled to one or more ozone output ports of an ozone supply unit. The pipe assembly further includes a second flow path fluidically coupled in parallel with the first flow path. The second flow path includes a control valve that selectively permits a portion of the water to flow through the second flow path to produce a negative pressure in the first flow path so that ozone is drawn into the first flow path through the one or more ozone intake ports and mixed into the water flowing through the first flow path.

A system and method for backwashing a sand filter in a wastewater treatment system. In one aspect, the invention can be a system for backwashing a sand filter comprising: a sand filter configured to remove solids from an untreated wastewater; a container storing chlorine fluidly coupled to the sand filter by a chlorine supply manifold; a flow control mechanism positioned on the chlorine supply manifold between the container and the sand filter, the flow control mechanism alterable between a first position whereby chlorine cannot flow from the container to the sand filter and a second position whereby chlorine flows from the container to the sand filter, the flow control mechanism being biased into the first position; and a processor operably coupled to the flow control mechanism and configured to automatically actuate the flow control mechanism into the second position upon detecting that the sand filter is being backwashed.
