Abstract:
A mobile waste processing system and method is disclosed for processing materials in a tank, typically an underground storage tank. A mobile fluid processing module is disposed adjacent to or over the tank, and sealingly connected to the tank through a tank riser. Support equipment, which may include an electric power module, a chiller module, a heating module, and a control and monitor module, are disposed a distance from the processing module, and connected thereto. A pump and optionally a dispersal nozzle are deployed from the processing module into the tank, and effluent is extracted for processing. The processing trailer includes effluent processing equipment such as an evaporator and demister, condenser, vacuum pump, and interim storage tank. The effluent is processed, and at least a portion is removed. Some of the processed effluent may be returned to the tank.
Abstract:
A mobile wastewater separator and recover unit and method for the separation and disposal/recovery of waste water for example in the oil and gas industry. It is fully self-contained and maintains the ability to separate heavy solids, floating contaminants, and water for recovery and reuse or disposal as required. Main components of the system are a large wastewater holding capacity implementing various compartments & separator/recovery mechanisms, evaporation compartments that are interchangeable for efficiency in both warm & extreme cold temperature operations, and finally a condensation recovery system and clean water holding compartment.
Abstract:
The present invention relates to an apparatus and method for the treatment of water and, in particular, an apparatus and method which may be applied to fluids such as grey water to be treated prior to discharge. The invention is intended for particular use on marine vessels such as house boats to treat grey water which at present is discharged untreated.
Abstract:
Methods of recovering hydrocarbons from an area that is contaminated or threatened with contamination with hydrocarbons may include deploying hydrophobic absorbent material such that at least some of the hydrophobic absorbent material contacts at least some of the hydrocarbons, allowing the hydrophobic absorbent material to absorb at least some of the hydrocarbons, and collecting the hydrophobic absorbent material from the area using a netting apparatus. The hydrophobic absorbent material may include cellulose treated with borax.
Abstract:
An oil skimmer conveyor includes an inclined frame attached to a boat or other structure. Upper and lower rollers are connected to the frame, and a continuous belt is supported by the rollers. The lower roller extends into the water, and is at least partially submerged in water. The belt is more permeable to water than to oil, and rotates about the rollers. Water passes through the belt, and oil is carried out of the water by the belt and collected in the boat.
Abstract:
A system for recovering floating oil from the surface of a body of water includes a sump vertically movably mounted between a pair of spaced interconnected floating pontoons. A hydraulic system is coupled to the sump for lowering the sump into the water below the pontoons to a predetermined depth. The forward wall of the sump is angled down and back from an upper edge and a blade is hingedly attached along the upper edge of the forward wall. In use, the sump is lowered into the water until the blade is at the proper slice depth to separate floating oil from the surface of the water as the pontoons are drawn through an oil spill in a forward direction. The separated oil is deposited immediately onto the angled forward wall where gravity causes it to accelerate downwardly along the angled wall. This “gravity drop” tends to pull or urge additional oil across the blade and onto the angled forward wall to enhance the separation of floating oil from the surface of the water. A wave plate extends above and forward of the blade to maintain the slice depth as the system encounters waves and to prevent waves from crashing into the sump.
Abstract:
An automated self-propelled pool cleaner having a housing, a water pump for moving water through the housing, drive means for moving the pool cleaner over the surface of the salt water pool to be cleaned, and an integral electrochemical chlorine generator mounted in the housing, includes a processor/controller that is programmed to activate the chlorine generator, the pump and drive means in predetermined operational sequences that minimize wear and tear on the water pump and drive means, while at the same time distribute and maintain a safe level of sanitizing chlorine in the pool, to thereby obviate the need for an in-line chlorinator or other chemical additive treatments; an optional automated sensor device can be provided to activate a secondary maintenance program which enables the pool cleaner to operate over prolonged periods of time as the sole means for filtering and sanitizing the pool water. An electrochemical cell manual mounting system permits the cell to be secured in place for operation and manually removed for maintenance, repair or replacement by the user without special tools or training.
Abstract:
A water treatment system using electrocoagulation is provided. One of the stages of the water treatment is subjecting the water to electrocoagulation so that colloidal solids can be reduced, emulsions broken, and hydrocarbons and complex organics removed, without the application of substantial chemical substances to the contaminated water or even the use of any chemical substances. An electrocoaguloaty apparatus can comprise: a tank having a first end and a second end; a plurality of electrolytic cells provided in the tank, each electrolytic cell having at least one anode electrode and at least one cathode electrode defining an anode/cathode electrode pair; and a voltage supply connected to each electrolytic cell to supply a voltage across each anode/cathode pair.
Abstract:
A self-cleansing portable urine collection device and method of collecting urine in a self-cleansing portable urine collection device is provided. The collection device includes a housing which houses a urine collection receptacle configured to collect urine from a user. A cleansing container which retains a cleansing solution is configured to supply the cleansing solution to the receptacle. The device further includes a reservoir coupled to the receptacle and configured to receive the urine and the cleansing solution collected by the receptacle. A pump coupled to the receptacle and the reservoir is configured to transport the urine and the cleansing solution from the receptacle to the reservoir.
Abstract:
An apparatus and method for reducing the scaling tendency of fracture-treatment flow back water and oil field brine by the precipitation of hardness salts using carbon dioxide as a carbonate donor. The apparatus includes a treatment conduit comprised of a plurality of segments. The treatment conduit includes a plurality of anode surfaces, a plurality of heated cathode surfaces each associated with an ultrasonic transducer and an arrangement for injecting carbon dioxide into the stream of raw water. The injection of carbon dioxide from an external source helps to reduce the pH of the water and to prevent scaling by softening the water thereby eliminating the use of HCL at the frac job site. The treatment conduit further includes a plurality of static mixers each creating hydrodynamic cavitation thereby facilitating better mixing of the carbon dioxide and higher mass transfer efficiency.
