20100282688 | Method of Raising the pH of Acidic Bodies of Water - The invention relates to a method of raising the pH of a body of water having a pH of less than 4.5 by introducing neutralizing agent, the raising of the pH taking place in at least two stages thus: at pH levels below 4.5, a first neutralizing agent having a final conductivity of not more than 100 μS/cm, and, after attainment of a pH of at least 4.5, a second neutralizing agent, having a final conductivity of more than 100 μS/cm, is introduced into the body of water, the final conductivity of the neutralizing agents being defined as the conductivity of an aqueous suspension or solution of neutralizing agent in solution equilibrium at 25° C., having a neutralizing agent content of 0.015% by weight. | 11-11-2010 |
20100300981 | WATER TREATMENT POND, SYSTEM AND METHOD OF USE - A pond receives a flow of contaminated water into the pond substantially tangential to a volume of clarified water which is stored in the pond and which is largely quiescent. The tangential inflow overcomes a large rotational inertia in the stored volume of clarified water and establishes a slow spiral flow path about the periphery of the pond and inwards to a central outlet. The clarified stored water is discharged ahead of the inflowing contaminated water increasing the residence time of the contaminated water in the pond and permitting contaminants to receive at least partial treatment, such as settling of sediment, in the pond. | 12-02-2010 |
20100314329 | DEVICE AND METHOD FOR CLEANING UP SPILLED OIL AND OTHER LIQUIDS - A device and method for cleaning up spilled oil and other liquids that are relatively less dense than water, that have spilled on the water or are borne on water or an other relatively dense liquid, and for separating oil and other liquids that are relatively less dense than water, from water or an other relatively dense liquids comprising an oil/water separation column having a lower end forming a bottom opening oriented substantially parallel to the surface of the body of water in fluid communication with the water and spilled oil, an air pump in airtight engagement with, and proximate the upper end of the oil/water separation column and adapted to draw water and the spilled oil into the oil/water separation column; and an oil pump in liquid tight engagement with and proximate the upper end of the oil/water separation column and adapted to draw the spilled oil from the oil/water separation column. | 12-16-2010 |
20100326924 | CO-DISPOSAL AND CO-STORAGE OF DESALINATION CONCENTRATED BRINE WASTE PRODUCT AND CARBON DIOXIDE WASTE PRODUCT - A method for disposal of desalination concentrated brine waste product from a desalination process provides that the desalination concentrated brine waste product is injected, along with a carbon dioxide waste product, typically into an imperviously capped porous rock formation, typically including a saline aquifer. The desalination concentrated brine waste product and the carbon dioxide waste product (i.e., which may be injected as a supercritical liquid) may be injected simultaneously or sequentially. The method provides for environmentally acceptable disposal of the desalination concentrated brine waste product and the carbon dioxide waste product. | 12-30-2010 |
20110017678 | Process for Rain Water, HVAC Condensate and Refrigeration Blowdown/Bleed Blowdown/Bleed Water Recovery, Water Quality Monitoring, Real Time Water Treatment and Utilization of Recovered Water - The present invention includes capturing water from rain, HVAC condensate and refrigeration blowdown/bleed blowdown that is recycled and reutilized in integrated mechanical processes. Water is monitored for volume, flow rate, and contaminants; and automatically cleaned through filtration and/or chemical and/or biological treatment techniques to meet acceptable health and safety standards for engineered end uses. The process components are integrated into an engineered system that includes: 1) water collection from air conditioning and refrigeration units and rain water; 2) custom design, engineering and implementation of a real time and/or scheduled water monitoring for water volume and water quality; 3) custom design, engineering and implementation of a real time and/or scheduled water treatment system to ensure water quality standards are met with respect to the end use of the recovered water; and 4) utilization of the recovered water by an engineered water distribution system. | 01-27-2011 |
20110031188 | Humic Derivatives Methods of Preparation and Use - Humic derivatives are prepared and used to adhere to the surfaces of mineral media and other hydroxyl-carrying supports for cleaning the environment by selective sequestration of complex mixtures of contaminants possessing preferential affinity for natural or modified humic substances (HS). The sequestration of target components occurs as a result of their binding to dissolved humic derivatives that can be removed from the solution by adding any solid hydroxyl-carrying support (e.g., silica gel). Another method to sequester the target components from solution is their selective sorption onto humic derivatives immobilized onto solid support (e.g., silica gel). Yet another method involves using the humic derivatives to install a broad spectrum reactive barrier without excavation as an in situ passive remediation system. | 02-10-2011 |
20110042324 | SYSTEM AND METHOD FOR WATER RESTORATION - A polarized distribution of positive flow sources are deployed to at least partially circumscribe one side of an oily patch floating in a water region and negative flow sources deployed to at least partially circumscribe the other side of the oily patch. Water emanates near the water line level from the positive flow sources and water is aspirated near the water line level by the negative flow sources, both water emanation and aspiration collaboratively causing the oily patch to move from the positive flow source side towards the negative flow source side. Aspirated water surfaces containing the oily patch are processed to separate oil from water and return the water to the water region. The positive and negative flow sources may be deployed near a boat slip, a marina, an oil rig platform, or in open water between boats, and may be supported by floatation devices. | 02-24-2011 |

20110062088 | FLUID FILTER SYSTEM AND RELATED METHOD - A system and related method for separating floating and nonfloating particulate and entrained, suspended, and/or dissolved contaminants from a fluid. The system includes a tank with a lower chamber spaced from an outlet or upper chamber by a confinement deck. The deck includes one or more sockets for receiving one or more filter units for fluid treatment. In addition, the lower chamber of the tank acts as a pretreatment sump to remove floating and nonfloating particulates, thereby reducing the load on the filter units. The filter units are configured for radial and/or upward flow of the fluid from the lower chamber. The filter units may include one or more filter media through which the fluid pass prior to exiting the tank. The filter units include a removable screening retainer for retaining the filter media and/or to screen relatively large contaminants. The filter unit may be removed for ease of tank maintenance and replacement of filter media. The system allows a method of contaminated fluid treatment under varying flow conditions by directing the fluid radially and/or upwardly through the retainer. Establishing both types of flow through the filter unit improves filtering and extends filter life without compromising desired flow through rates. | 03-17-2011 |
20110108492 | External Filtering and Absorbing Device for Use in a Local Containment Area - An External Filtering and Absorbing Device for Use in a Local Containment Area contains filter material with a mesh size not less than 50 microns for removing contaminants from ballast or bilge water from a ship or effluent from a storm drain. Examples of contaminants removed are aquatic nonindigenous species such as Fish, Zebra and Quagga Mussels, Asiatic Clam, Aquatic Weeds, Green Crabs, or other suspended particle contaminants. Filtering is accomplished above the ambient water allowing easy visual verification and visual gratification of the efficacy of the filter unlike closed on-board systems. Water and oil permeate the filter and flow into a local containment area where oil is absorbed by absorbent pads held in pockets. The filter is easily removed and can be sent to authorities to demonstrate compliance with environmental standards. Water sampling containers or instruments used with the assembly allow for further compliance monitoring. | 05-12-2011 |
