    Abstract: The method of solvent recovery includes using a plurality of solvent recovery units to recover solvent from a dilute solution. The solvent recovery units can include a plurality of reverse osmosis or forward osmosis membrane systems arranged in series. For reverse osmosis, at least some of the concentrate in a last reverse osmosis unit of the series is recycled back to the permeate of that unit to provide a mixed permeate. The mixed permeate is then passed successively to the permeate side of each preceding reverse osmosis unit in the series. For forward osmosis, a draw solution is passed sequentially from the permeate side of each unit to the permeate side of the preceding unit. The draw solution may be prepared by concentrating part of the concentrate stream by evaporation and recycling it back as a draw solution.

  • Patent number: 9719111
    Abstract: A multi-stage anaerobic digester is designed to treat a high solids, stackable feedstock. The system may also receive a pumpable feedstock such as a slurry or sludge. In a first stage, the digestate circulates in one direction around a raceway such that the digestate may pass a feed inlet multiple times before leaving the first tank. An optional side stream loop withdraws fibrous material from near the top of the reaceway and return digestate with chopped fibers, preferably lower and further along the raceway. An outlet from the raceway located near, but upstream of the feed inlet discharges partially digested substrate to a second stage, which is operated as a stirred tank reactor. The two stages may be provided in a single tank with an internal wall separating a ring shaped outer portion from a cylindrical inner portion. The digester may be operated in a thermophilic temperature range.

  • Patent number: 9115701
    Abstract: A method of converting thermal energy into mechanical work that uses a semi-permeable membrane to convert osmotic pressure into electrical power. A closed cycle pressure-retarded osmosis (PRO) process known as an osmotic heat engine (OHE) uses a concentrated ammonia-carbon dioxide draw solution to create high osmotic pressures which generate water flux through a semi-permeable membrane against a hydraulic pressure gradient. The depressurization of the increased draw solution volume in a turbine produces electrical power. The process is maintained in steady state operation through the separation of the diluted draw solution into a re-concentrated draw solution and deionized water working fluid, both for reuse in the osmotic heat engine.

  • Publication number: 20150076068
    Abstract: Described are methods in which the retention times of a chromatographic column are adjusted through the control of the temperature of a mobile phase at the inlet to the chromatographic column. The temperature of the mobile phase at the inlet is different from the temperature of the chromatographic column. Adjustment of the temperature of the mobile phase at the inlet can be used as part of a method to transfer a chromatographic method from one liquid chromatography system to another liquid chromatography system. The method can alternatively be adapted for trapping a sample at the head of a chromatographic column to reduce the amount of band broadening of the sample from the sample injector of a liquid chromatography system. A gradient elution can then be performed to cause the concentrated volume of the analyte in the sample to elute in a tight band, resulting in improved measurement sensitivity.

A novel small-scale self-regulating spray dryer preserves temporal resolution while desolvating a liquid chromatography eluent stream and depositing the solute onto an optical surface for infrared spectrographic analysis. The liquid eluent is pumped through a heated nebulizer to create a high-speed jet of solute containing liquid and solvent vapor. This jet is directed circumferentially inside a hot cylindrical cavity. Centrifugal force causes the larger liquid droplets to travel along the outer diameter of the cavity. The cavity surface is heated to cause the droplets to film boil. Film boiling reduces droplet contact with the cavity surface thereby retaining the solute in the droplets. The solute temperature is limited by controlling the pressure into which the solvent evaporates from the droplets.

  • Publication number: 20140151276
    Abstract: A wastewater geothermal heat system is supplied with processed wastewater through a drip field in proximity to a thermal array part of a geothermal heat pump system. The wastewater treatment system portion provides a periodic source of treated wastewater. Several sensors and a control system regulate a pump that discharges wastewater from the treatment system and enters a drip field where it is released into the surrounding soil. The dampened soil provides an efficient vehicle to transfer heat into or out of a thermal array which is positioned adjacent to the drip field such that it is in contact with the soil that is dampened by the discharged wastewater.

  • Publication number: 20140151300
    Abstract: Processes and systems for treating high salinity aqueous liquids containing dissolved minerals, suspended solids, colloidal solids, free oil and grease, dissolved organics, and dissolved hydrocarbons. The liquid is passed into an electrocoagulation system in fluid communication with a solids removal clarifier, pressurized ultrafiltration system, the draw side of forward osmosis, and a dilute draw water reverse osmosis system. Impaired water with high sulfate content is used as a source of deionized water for dilution of the forward osmosis draw solution. After concentration, the forward osmosis feed solution is further treated by lime soda softening and sludge from the softening system may be recycled to increase hardness precipitation and silica removal, the outfall from which may be treated by a separate ultrafiltration system and a feed water reverse osmosis system. Concentrate from the feed water reverse osmosis system can be treated to offer a zero liquid or near zero liquid discharge.
