The new solids settler design includes a liquid inlet means that injects the feed to the solids settler into an inner coagulation chamber of the solids settler. The liquid inlet means directs the flow of the feed so that the feed flows in a circular pattern within the coagulation chamber.Type: ApplicationFiled: August 15, 2001Publication date: February 20, 2003Inventor: Dinh-Cuong Vuong

Publication number: 20030034300Abstract: A simple, reliable, inexpensive, and efficient anaerobic digester for treating organic wastes at a shortened residence time is described. The anaerobic digester is a multi-chambered digester that can handle wastewater and sludge in a large volume at a high flow rate. The digester also allows collection of methane gas for use as an energy source. The reactor is based on a sequential series of reaction chambers in a design that does not require internal moving parts. The volume of the chambers is adjusted to control the relative residence time of the waste to select an anaerobic microorganism group or groups that can efficiently digest the waste presented to that chamber. Under most conditions, no addition of bacteria is necessary. The digester works efficiently using microbes native to the waste material. After the reaction chambers and just prior to leaving as effluent, a settling chamber is located to reclaim the microbes and remove additional solids.Type: ApplicationFiled: August 1, 2001Publication date: February 20, 2003Inventors: Vadake R. Srinivasan, John J. Sansalone

Publication number: 20030034301Abstract: Methods and apparatus are disclosed for recovering metals from metal-containing support materials such as mineral ores. In one embodiment, the metal may be separated from crushed support material or ore in a bioleaching lagoon by the action of hydrocarbon-utilizing bacteria under anaerobic conditions. The bioleached material is then pumped into a precipitation lagoon where hydrocarbon-utilizing bacteria oxidize the metals under aerobic conditions. In another embodiment, metals may be directly biooxidized from a heap of the metal-containing support material having a hydrocarbon/oxygen injection system embedded therein. A water sprinkler system may be used to wet the heap while the hydrocarbon/oxygen injection system stimulates the growth of hydrocarbon-utilizing bacteria. The resulting effluent solution may be pumped or gravity fed to an aerobic precipitation lagoon where aerobic hydrocarbon-utilizing bacteria are used to precipitate or otherwise deposit the metals onto a deposition material.Type: ApplicationFiled: July 26, 2002Publication date: February 20, 2003Inventor: Felix Anthony Perriello

Publication number: 20030034302Abstract: An insecticide delivery apparatus may include an insecticide extraction chamber having an outlet adjacent a lower end thereof, and a screen adjacent the outlet for holding a mass of insecticide bearing bodies to partially fill the insecticide extraction chamber. A nozzle may be positioned adjacent an upper end of the insecticide extraction chamber for directing a water stream downwardly therefrom toward the mass of insecticide bearing bodies. An air control device may control the water level and associated head space so that the insecticide bearing bodies are at least partially submerged in the water. The bodies may be churned in the water by action of the stream to enhance delivery of insecticide into the water. The apparatus may provide efficient and cost effective control of a number of insects, such as midge flies, that are prevalent in a trickling filter of a typical wastewater treatment plant.Type: ApplicationFiled: August 20, 2001Publication date: February 20, 2003Applicant: PRECISION CONTROL TECHNOLOGY, INC.Inventors: Patrick M.

Publication number: 20030034304Abstract: A composite membrane is provided comprising a porous substrate membrane coated with a membrane comprising N-acetylated chitosan. The N-acetylated chitosan is characterized by a degree of N-acetylation greater than 50% and less than 90%. The porous substrate membrane includes any of polyvinylidene fluoride, polysulfone, and a ceramic. In this respect, composite membrane is provided comprising: a first layer including N-acetylated chitosan, and a second layer including a porous substrate membrane, wherein the first layer is coated upon the second layer. A method of forming a composite membrane is also provided comprising the steps of: forming a porous substrate membrane, depositing chitosan solution on the porous substrate membrane to form a first intermediate, drying the first intermediate to form an intermediate composite membrane including a chitosan membrane, and acetylating the chitosan membrane.Type: ApplicationFiled: August 17, 2001Publication date: February 20, 2003Inventors: Robert Y.M.
