摘要： The present invention provides a system and methods for filtering fluid using filter papers, stationary paper, cloth sheets or any other porous material. In one embodiment, the present invention uses the lateral flow direction along the porous sheets, instead of conventional vertical flow direction, for the removal of bacteria and particle contamination in the range from nanometers to millimeters. The pore sizes in the filter media along the lateral direction are modulated by controlling the compression of the porous sheets, instead of conventionally designing filters with different pore sizes. The lateral flow fluid filter system is scalable simply by increasing the feed area, feed length, and the number of porous sheets. The invention presents a universal fluid filtration system for wide range of applications such as water purification, food processing, chemical industry, oil and gas industry, and biological applications.

摘要： A system and method for in situ dewatering and stabilizing waste material deposits previously created from sluicing into a waste impoundment. The method includes access for installation of wells and grading for surface drainage and storm water control. If free water is present, primary dewatering siphons or decants the free water in the pond. The system includes vertical dewatering well installation that requires drilling, well completion materials for filtering leachate, and well pump installation for removing leachate from the well. Collection piping collects leachate from the wells and transfers the leachate to a discharge solution. The dewatering operation collects and removes leachate from the pond ash deposit and impoundment, reuses or treats the leachate at a discharge solution, remediates contaminants and/or hydraulic head in the impoundment, and consolidates and stabilizes the dewatered solids. Impoundment closure includes horizontal drains, final grading, final cover or overfill landfill development, and post closure.

摘要： A process for the desalinization of sea water which includes a barrier buried to a depth below the low tide water level in a sandy beach, and a collector vault or well buried in the beach behind the barrier, the well having an opening in its side for receiving water passing through the barrier. The barrier is filled with selected filter materials, and the sand in the area between the barrier and the well is treated with a selected material. The barrier extends through a water-permeable layer of crushed or fossilized shells naturally occurring beneath the sandy beach. The well opening is positioned within this shell layer. After a period of pumping, desalinated water will appear in the well and may be pumped out of the well. Whenever the water in the well is pumped below a particular level, a new supply of desalinated water will flow in through the opening in its side from the barrier.

摘要： Devices and methods associated therewith for facilitating movement, removal and/or installation of components from treatment units (e.g., water treatment units and wastewater treatment units). The treatment unit can take the form of a granular media filter (e.g., upflow filter, downflow filter or bi-flow filter) or a sludge collection basin. One preferred device is one or more floats facilitating safe removal of components of a treatment unit. The float(s) can be operably associated with an air scour system of a water filter to remove the air scour system from a granular media filter bed. The float(s) can be operably associated with a collection grid of a sludge collection container facilitating safe removal of the collection grid from the sludge collection container. Another preferred device is a flexible piping/conduit operably connected to a pressurized air source and an air scour system to assist in removal/installation of the air scour system.
