Title: Method for stabilizing and conditioning urban and industrial wastewater sludge
Inventor: DROGUI PATRICK
IPC: C02F1/66
Filed: 2002-11-29
Abstract: The invention concerns a method for stabilizing and conditioning wastewater sludge. The invention is characterized in that it consists in treating sludge in an acid environment (3.0<=pH<=5.0), with an inorganic acid and two oxidizing agents, that is a ferric iron salt and hydrogen peroxide. The ferric iron salt is used in such an amount as to obtain a concentration ranging between 5 and 40 kg of Fe per ton of dry sludge; the hydrogen peroxide is used in such an amount as to obtain a concentration ranging between 5 and 40 kg of H2O2 per ton of dry sludge; mixing the treated sludge for a time interval sufficient to stabilize the sludge and improve its dehydrability; then flocculating the stabilized sludge by adding an organic polymer; then dehydrating the flocculated sludge. Said method enables to significantly improve the dehydrability properties of the sludge while increasing the dry solid content during its mechanical dehydration.

Inventor: FRIEDMAN MITCHELL A
IPC: G05D11/00
Filed: 2002-05-09
Abstract: Disclosed is a fluid dispensing system for precisely controlling mixing of a first fluid (i.e., a diluent such as water) with a s econd fluid (i.e., a concentrate) at a mixing point within the s ystem. A valve (10) is positioned in the system along the line ofsupply (501) of the second fluid upstream of the mixing point (701), such valve (10) being simultaneously actuated through applic ation of positive and/or negative pressure to allow the second fluid to flow through the valve (10). The pressure is generated fr om the first fluid to be dispensed by the system and mixed with the second, such that the termination of flow of the first fluid immediately terminates flow of the second fluid to ensure proper mixing of the two fluids in the final solution, thus preventing inadvertent leakage of the second fluid or collection of the second fluid within the flow system which may become subject to spoila ge or contamination.

Abstract: Méthode pour former plus rapidement un modèle stochastique de type gaussien ou apparenté, représentatif d'un milieu hétérogène poreux tel qu'un réservoir souterrain, contraint par des données caractéristiques du déplacement des fluides et des observations ponctuelles, ces observations étant incertaines et caractérisées par une loi de probabilité. Elle s'appuie sur une méthode de transformation de l'information statique, donnée sous forme de lois de probabilité, en pseudo-données ponctuelles gaussiennes. Cette technique de transformation présente l'avantage d'être intégralement compatible avec une méthode de déformation graduelle. De fait, elle rend possible la minimisation d'une fonction objectifJ mesurant l'écart entre les données dynamiques (données de production par exemple) et les réponses correspondantes simulées pour le modèle de réservoir considéré. La minimisation est menée en combinant des réalisations d'un modèle stochastique d'une part pour le modèle de réservoir et d'autre part pour les pseudo-données gaussiennes représentatives de l'information statique. Au cours du processus de minimisation, on ajuste les coefficients de combinaison et on identifie les réalisations qui permettent de réduire la fonction objectif. Applications notamment à  l'exploitation de gisements pétroliers par exemple.

Filed: 2005-08-29
Abstract: The present invention extends to methods, systems, and computer program products for organizing resources into collections to facilitate more efficient and reliable resource access. Namespace managers communicate with one another to form a federation namespace infrastructure. The infrastructure can efficiently route, migrate, and process namespace requests, such as, for example, namespace registration requests from providers requesting to manage portions of namespaces and lookup requests from consumers requesting access to managed resources. Resources can be registered in and made accessible from multiple different namespaces. Resources can be identified using nested queries that filter results at multiple levels of a hierarchical namespace.
