摘要： In a multistage osmosis treatment method including: subjecting liquid to reverse osmosis treatment in a first-stage reverse osmosis separation module (31); adding an alkali agent to the obtained permeated water (5) to adjust a pH value of the permeated water (5) in an alkaline region; and further subjecting the permeated water (5) to reverse osmosis treatment in second and subsequent stage reverse osmosis separation modules (32), the supply water (5) to the second-stage reverse osmosis separation module (32) is subjected to at least one treatment selected from deferrization, demanganization, decarboxylation, and addition of a chelator and a scale inhibitor. Because of this, multistage reverse osmosis treatment is provided, in which the separation performance of the second and subsequent stage reverse osmosis membrane modules is enhanced, and liquid can be separated and purified to a high degree, and boron and the like that are not dissociated in a neutral region can be separated at a high blocking ratio.

摘要： An animal treatment method comprises flushing the animal waste from a barn to a holding tank where the waste is mixed with an alkaline solution to kill pathogens. After neutralization, the solution is separated into solids and liquids. The liquid is treated and recycled as flushing water to clean the barns and/or drinking water for the animals. The solids are separated into digested and undigested feed. The digested feed is further processed for use as a fertilizer and the undigested feed is processed for use as animal feed.

摘要： A method and system for removing volatile organic compounds (VOCs) from sludge advantageously utilizes a stripper for removing the VOCs directly from the sludge to convert the sludge into a non-hazardous material. Preliminary steps of mixing may include addition of a liquid to improve flowability. Then the sludge is moved through the stripper in which the VOCs are carried away in a gas provided in the stripper for the purpose of carrying the VOCs away. Any of a variety of strippers may be utilized for VOC removal. Subsequently, the liquid is separated from the sludge material in, for example, a dewaterer, and each of the liquid and the sludge is either recycled or dumped as a non-hazardous material or waste. The system may be configured in a variety of ways and still function properly in carrying out the method of the invention.

摘要： A hydraulic system includes a storage tank, a cover assembly and a filter assembly for filtering hydraulic fluid, gasses and air. The tank includes an opening and an attachment ring bounding the opening. The cover assembly has an inlet port and is removably connected to the attachment ring to support and enclose the filter assembly in the tank. The filter assembly includes a filter element having a filter media ring for filtering hydraulic fluid, and an annular breather filter surrounding the filter media ring at one end of the ring for filtering vent gas and air. The filter element is supported in a diffuser tube received in the tank opening. The diffuser tube includes a stand-off ring with a convoluted groove or channel to provide a vent path between the diffuser tube and the tank opening to direct vent gasses and ambient air through or around the breather filter.
