An apparatus for separating water from oil-based drilling fluid includes an separation tank, a chemical treatment apparatus having one or more de-oiling polymer preparation tanks, and a dissolved air flotation unit. Slop mud is directed into the separation tank where surfactant is added to separate the drilling fluid from oily water. The drilling fluid is drained for further processing. The oily water is removed by an outlet arrangement from the separation tank and directed to an initial treatment line. One or more de-oiling polymers are added to the oily water in the initial treatment line and mixed therewith. The mixture may then be directed to the dissolved air flotation unit where dissolved air is released into the bottom of the mixture. The dissolved air adheres to suspended solids in the mixture and lifts them to the top surface as a froth. The froth is skimmed from the top surface of the mixture and collected. The de-frothed water is reused or directed to a filtration system where it is prepared for discharge. A clarifying tank may be included after the de-oiling polymers are added to further separate the oil and water. The oil is removed from the top surface by a weir while the water is directed to the filtration system and discharged.

A composite building material includes carpet waste having carpet fibers and adhesive, and an inorganic filler that includes fly ash.

The composite building material may optionally include a base polymer, slack wax, and/or calcium carbonate.

Disclosed are systems and methods of plating a tin alloy in an efficient, economical, and environmentally friendly manner. The system for plating a tin alloy contains an electrochemical cell containing an anode, the cathode, and an electroplating bath. The electroplating bath contains water, an acid, at least one nitrogen-containing heterocyclic complexing agent, an ionic alloy metal, and ionic tin. The methods involve applying a current to the electroplating bath whereby a tin alloy forms on the cathode.

This invention describes a microengineered SFC system for rapidly and efficiently separating the constituents of a complex mixture. The SFC system includes a microchannel that is microfabricated from a suitable substrate so that it forms a chromatographic column for separation of chemicals. The surface area of the microchannel of the column is sufficiently small as to permit use of miniature and relatively inexpensive pumps, and the thermal mass of the microengineered column is sufficiently low as to permit rapid temperature cycling using a miniature, low power and inexpensive heating element. At least a portion of this microchannel is packed with suitable sorbent materials or includes surfaces which are suitably coated with sorbent, or both, so as to retain and elute analyte under certain conditions. As a result analyte passing within this microchannel undergoes chromatographic separation.

Disclosed are systems and methods of plating a tin alloy in an efficient, economical, and environmentally friendly manner. An electrochemical cell containing an anolyte compartment and a catholyte compartment separated by a selective membrane is employed. The selective membrane prevents ionic metals from migrating from the catholyte compartment to the anolyte compartment. A conduit may be employed in the electrochemical cell to permit one way flow of anolyte to the catholyte compartment thereby replenishing tin to the catholyte compartment.

The present invention relates to activated carbon sorbents including nitrogen. In various embodiments, the present invention provides an activated carbon sorbent including a halogen- or halide-promoted activated carbon, the activated carbon sorbent particles including nitrogen in a surface layer of the sorbent particles. In various embodiments, the present invention provides a method of reducing the pollutant content in a pollutant-containing gas using the activated carbon sorbent. In various embodiments, the activated carbon sorbent can remove mercury from a mercury-containing gas that includes sulfur(VI) such as SO₃ more efficiently than other sorbents.

A mobile water treatment apparatus to on-load a dirty fluid into a storage container attached to a motor vehicle and transport the fluid in the storage container from a first location and to a second location where the fluid is filtered by a filtration system attached to the motor vehicle. The filtered fluid is discharged from the mobile water treatment apparatus at the second location.

Provided is a technique for accurately taking out a defect detected by an electron beam, and for analyzing the defect. In this technique, a defective portion in a wafer is detected by the irradiation of the electron beam. A mark made of a deposition layer is formed by irradiating the electron beam onto the defective portion while supplying a deposition gas thereto. On the basis of this mark, the defective portion is machined into a sample piece by using a projection ion beam generated from a gas ion source, and thereby the defective portion is taken out.

A process for anti-microbal textile treatment which provides durable and anti-microbial textiles and methods for preparing same. Such textiles can be readily prepared using a wet curing process to covalently attach a Complex Formula Compounds to a cellulose based material or other polymeric material. Once prepared, the textiles of the present invention have a broad spectrum of biocide activity against pathogenic microorganisms, and durability and efficacy of the antimicrobial properties.

A safety needle assembly having a rigid housing that encloses a locking mechanism, an actuator that is operable to slide a sheath over the tip of the needle to prevent accidental sticks after the needle has been used, and an actuator that is operable in response to the final end movement of the syringe plunger to effect movement of the actuator over the needle tip. The housing is made in a standard size that is mountable on a connection port formed on a syringe barrel that can have a much greater diameter than the connection port. An adapter is provided for mounting a standard needle having a Luer lock to enable a health care professional the flexibility to use conventional needles to load medicine into the syringe barrel then replacing with a safety needle assembly for injection of the medicine.

The present invention relates to sorbents including carbon and nitrogen. In various embodiments, the sorbent can remove mercury from a mercury-containing gas that includes sulfur(VI) such as SO₃ more efficiently than other sorbents. The sorbent can include a graphene edge comprising an active site for mercury oxidation and a nitrogen layer structure including cationic nitrogen atoms, neutral nitrogen atoms, or a combination thereof proximate the active site.
