A fat-soluble metal containing substance comprising an organic anion and a metallic cation is added to the oil. The metal containing substance may be prepared by allowing a metal ... 03/29/07 - 20070068876 - Sludge treatment method and sludge treatment apparatus A sludge treatment method allowing an improvement in a phosphorus recovery rate and sludge volume reduction by efficiently eluting phosphorus in the sludge. The sludge treatment method includes: a step of foaming a sludge-containing liquid by blowing an ozone-containing gas into the sludge-containing liquid; and a step of eluting phosphorus ... 03/15/07 - 20070056913 - Portable oil field waste water treatment and recycling system A method is shown for treating oil field waste waters associated with drilling, completion and production operations. An ozonation process is used as a pre-treatment to a flocculation process in the continuous treatment of oil field drilling and production reserve pit waste water. The treated water has been found to ... 02/08/07 - 20070029263 - Multi-functional oxidizing composition A composition comprising a stable anhydrous mixture of an oxidizing agent and an active halogen agent wherein the oxidizing agent is potassium hydrogen peroxymonosulfate and the active halogen agent is an alkali metal salt of dichloro-s-triazinetrione, halogenated dimethylhydantoin, or mixtures thereof, and a method of treating water with such compositions ... 12/21/06 - 20060283805 - Advanced separator system A method for the remediation of contaminated liquid stream wherein liquid is passed through a reactor loop before entering tank and reactor loop is a series of conduits with internal baffles with openings wherein reactor loop causes ionization in the liquid stream before entering tank wherein liquids are additionally passed ... 10/19/06 - 20060231497 - Waste water treatment A process for treating waste water which contains soluble phosphorous, the process including the step of reacting the soluble phosphorous with a source of magnesium ions under reaction conditions to produce a phosphorous containing precipitate. ... 06/01/06 - 20060113254 - Extraction and treatment of heavy metals Contaminated waste streams or soil or sludge is subjected to a first treatment stage with an acid liquor at a pH below 2 and at a solids content from 5 to 30%; then the liquid and solid phases from the first treatment stage are separated; the solids from the first ... 05/04/06 - 20060091082 - Treatment of brown grease The invention is a process for treatment of brown grease, where the brown grease comprises water, food solids and free-oil. This process starts with the collection of the brown grease into a container. The brown grease's pH is adjusted with a chemical treatment to produce an adjusted brown grease phase. ... 11/03/05 - 20050242043 - Method for removing cryptosporidium oocysts from water A method for stabilizing and removing Cryptosporidium oocysts or Giardia cysts from water. The method comprises adding chitosan, a salt or solution of chitosan to water containing Cryptosporidium oocysts or Giardia cysts and a halogenating agent. The method may also include adding a secondary polyelectrolyte flocculant to the water. The ... 10/27/05 - 20050236336 - Method and apparatus for water treatment Water is treated by precipitating dissolved contaminants. A treatment vessel is provided having an inlet for receiving the water under treatment and an outlet for flowing treated water therefrom. A high volume of fine air bubbles are diffused into the water within the vessel as it flows therethrough, causing the ... 07/07/05 - 20050145575 - Sludge treatment method and sludge treatment apparatus A sludge treatment method allowing an improvement in a phosphorus recovery rate and sludge volume reduction by efficiently eluting phosphorus in the sludge. The sludge treatment method includes: a step of foaming a sludge-containing liquid by blowing an ozone-containing gas into the sludge-containing liquid; and a step of eluting phosphorus ... 06/23/05 - 20050133455 - Process for removing arsenic from drinking water Arsenic is removed from water and other aqueous feeds by (1) treating the feed with a compound containing cerium in the +4 oxidation state, preferably cerium dioxide, to oxidize arsenic in the +3 oxidation state to arsenic in the +5 oxidation state and (2) removing the arsenic in the +5 ... ### FreshPatents.com Support |
