Filed:

May 5, 2003

Appl. No.:

10/430171

Inventors:

Curtis S. McDowell - Allentown PA, US
Chris Hannum - Oley PA, US
Robert Maurer - Shillington PA, US

Assignee:

Brentwood Industries, Inc. - Reading PA

International Classification:

C02F003/00

US Classification:

210620, 210220, 210739, 210745, 2101951, 210 97

Abstract:

The invention relates to an aerobic wastewater digestion unit useful for degrading organic material dissolved or suspended in a wastewater stream. The wastewater is fed to a vessel, wherein it is circulated by a liquid conveyor between the vessel and a downwardly-directed tube. Expulsion of fluid from the tube into the lower portion of the vessel agitates the liquid in the vessel and disperses into the liquid air that has been entrained in the liquid in the tube. The digester can be operated using varying liquid levels, and is amenable to batch, semi-batch, and continuous operation. The digester is suitable for use in combination with other components of wastewater treatment systems, and can be included as a module in modular wastewater treatment systems.

Abstract:

The invention relates to a liquid clarifier useful for removing solids suspended in a wastewater stream. Settled biological solids are taken from the clarifier and combined in a mixing chamber with a wastewater stream. The combined liquid is provided to a settling region of the clarifier, and suspended solids settle in a biological solids collection region, from which the solids are taken. Clarified liquid can be withdrawn or permitted to overflow from an outlet region in the settling region of the clarifier. The clarifier can enhance the degree of solids removal from wastewater streams having relatively low total suspended solids values, such as outlet streams from fixed film-type digesters. The clarifier is suitable for use in combination with other components of wastewater treatment systems, and can be included as a module in many kinds of wastewater treatment systems.

US Classification:

427 228

Abstract:

The present invention provides improved medical devices for use in surgical procedures and methods for manufacturing improved medical devices. In some embodiments, the improved medical devices can include improved surgical needles that are capable of being repeatedly passed through tissue using minimal force. More particularly, the improved surgical needles can be manufactured with two or more different coatings that provide the surgical needles with both durability and lubricity for ease of repeated and successive passes through tissue. Improved methods for manufacturing the surgical needles and for providing and applying coatings to the surgical needles are also provided.
