  • Patent number: 10377642
    Abstract: A laser ablation and filtration process and apparatus wherein liquid containing hydrocarbons or other contaminates is purified. The liquid is exposed to laser energy at one or more selected wavelengths wherein the laser energy travels through the liquid and reaches the hydrocarbons or other contaminates and vaporizes, denatures, breaks down, neutralizes, renders inert and/or separates the hydrocarbons or contaminates from the liquid. A laser source is positioned in or on a vessel based on pre-set parameters to maximize exposure of the liquid to the laser energy, including sizing parameters, angle and inclination of the laser, retention time for the laser process to be applied and geometry of the containment for proper inclination. One or more collection chambers, which may include perforated membranes may be included to collect gases, separated hydrocarbons or contaminates and other by-products of the process. The vessel utilized may be submergible in water to pull or flow contaminated water therethough.

  • Patent number: 10358784
    Abstract: A vegetated or non-vegetated buffer water retention system. The current invention can be utilized for both smaller scaled (e.g., residential or commercial) purposes or larger scaled (e.g., agricultural, municipal, industrial) purposes. In certain embodiments, the system generally includes a perforated drainage pipe and an elevated overflow controller apparatus (e.g., T-shaped member, arched overflow valve apparatus) in open communication with each other. These components allow the system to control the soil matrix water table. With additional valves, pumps, and water reservoirs, the system can control both the soil matrix water table and stored water reuse. The systems can be used not only to enhance plant root uptake and microbial utilization of nutrients and pollutants in water, but also to capture and reuse water inflows, thereby aiding in flooding abatement, water conservation and preventing soil erosion.

  • Patent number: 10328364
    Abstract: A process for removing hydrocarbons and water from hydrocarbon and/or water containing drilling waste. The process includes introducing hydrocarbon contaminated drill cuttings and a cleaning solvent into a solvent wash tank. Prior to introducing the hydrocarbon contaminated drill cuttings into a solvent wash tank, the hydrocarbon contaminated drill cuttings are treated with a hydrocarbon solvent such as hexane to break the surface tension of the hydrocarbons in a solvent sealed vertical centrifugal separator to remove hydrocarbons from the hydrocarbon contaminated drill cuttings, resulting in improved efficiency of the hydrocarbon removal process. Apparatus for performing the process is also described.

  • Patent number: 10301189
    Abstract: The continuous treatment of a flow of organic liquid sludge is disclosed. Following the optional addition of granular mineral matter to the flow, the sludge is injected at a rate q into a column of air which is at overpressure relative to atmospheric pressure. The air column is circulating at a rate Q>5q in a chamber extending over a specific length in order to create a fluidized bed, in which the sludge is aerolized, between air supply piping upstream of the sludge injection and an outlet reservoir downstream of the fluidized bed, the reservoir being substantially at atmospheric pressure. A flocculant is introduced continuously downstream of the chamber into the fluidized bed in order to aggregate the organic matter before the solid part obtained in this way is separated from the liquid part, the resulting solid part thus being deodorized.

  • Patent number: 10272187
    Abstract: Embodiments of the disclosure include a method and system for estimating flow rates of a fluid or medium though a dialyzer during a dialysis treatment (e.g., a hemodialysis treatment). Pressure sensors are incorporated in dialyzers used for hemodialysis to achieve continuous monitoring of fluid balance of the body. During dialysis, obtaining fluid input and output pressures experienced at various inlets and outlets of dialyzers is easier than obtaining flow rates at these inlets and outlets, but using flow rates is better in determining the effectiveness of a dialyzer during hemodialysis. Embodiments of the disclosure thus use pressure measurements at inlets and outlets of a dialyzer along with a dialyzer model to determine fluid flow rates through the dialyzer. The fluid flow rates are used to determine whether there are leakages or occlusions in tubing during the dialysis treatment.
