Process to remove transition metals from waste water
10683223 · 2020-06-16 ·

A process to remove transition metals from waste water. The process includes the steps of passing waste water to a first pH resin bed, monitoring the effluent from the first resin bed, and adjusting pH to greater than 4. The effluent is passed to a first stage liquid tank and to a first brackish water membrane to filter out complex metals. Rejected effluent from the first brackish water membrane is passed to a second stage liquid tank and thereafter to a second brackish water membrane. The permeate from the second brackish water membrane is passed back to the first stage liquid tank. The rejected effluent from the second brackish water membrane is heated and evaporated. The evaporated effluent is condensed so that metal crystals are gathered for disposal. The permeate through the first brackish membrane is passed to an EDTA resin bed to sequester metal ions. The pH of the discharge from the second pH resin bed is adjusted to between 7 and 11.

20200131050 · 2020-04-30 ·

A method and an apparatus for isolating potentially harmful medical substances, such as antibiotics, is disclosed. An aqueous composition, such as blackwater, contains potentially harmful medical substances present in dissolved state in bodily waste. The aqueous composition is temporarily stored in a buffer tank and is then transferred in batches to a vaporization unit comprising one or more vaporization chambers for producing a water-reduced waste material containing said potentially harmful medical substances. The waste material is subjected to a destructive treatment, such as a high-temperature incineration process.

Canopy Wick For Extreme Heat Transfer And Small Resistance
20200064078 · 2020-02-27 ·

A flow-boiling canopy wick (FBCW) employing film (meniscus) evaporation and perforated distribution layer separating the liquid stream from the underlying vapor space is provided. The vapor vents continuously through periodic perforations, in contrast to plain surface which becomes completely covered by vapor at high heat flux. The FBCW allows streamwise liquid tracks on the distribution layer between perforations providing capillary liquid flow toward heated surface and evaporation on high-effective-conductivity monolayer wick. Under extreme heat flux, various hydrodynamic limits prevent liquid supply and vapor removal, i.e., the capillary-viscous, wick superheat, perforation pressure drop and chocking and liquid-vapor stability limits. The liquid and vapor inertia control the streamwise continuous liquid track (with isolated and/or merged vapor track) and, for saturated water at 1 atm CFD and wick pressure drop, predict heat flux up to 0.1qmax=20 MW/m.sup.2, an order-of-magnitude larger than the nucleate flow-boiling limit.

COMBUSTION OF STREAMS DERIVED FROM HOT WATER EXTRACTION OF WOOD MATERIAL

Various techniques are described for enhanced combustion of hot water extraction (HWE) derived liquor. For example, the HWE derived liquor can be pre-treated prior to introduction into a combustion chamber. The pre-treatment can include subjecting HWE derived liquor to filtration to remove suspended solids, evaporation to produce a first stage concentrated HWE liquor; additional concentration to produce a second stage concentrated HWE liquor; additional filtration to remove additional suspended solids; and pre-heating to produce a preheated HWE liquor. The preheated HWE liquor can be atomized and combined with pre-heated combustion air supplied into a combustion chamber to effect combustion of the HWE derived liquor.
