摘要： A filtration system using lightweight fibrous media (LFM) that are pre-compressed either 1) manually; or 2) in-situ using hydraulic flow; and where the LFM are forced to separate and relax for cleaning either: 1) manually, 2) in-situ in their filter housing, or 3) in an auto-clean system using separate devices in order to enact a particularly aggressive cleaning process. A plurality of lightweight fibrous media balls are pre-compressed and used to form a single mass that can filter water as the media are compressed by pre-compression before installation, or by water flow pushing on a pre-compression plate during filtration thereby forming a single mass providing multitudes of tortuous paths through which water can flow and the media can capture small particulate matter.

摘要： Materials which react with (“scavenge”) sulfur compounds, such as hydrogen sulfide and mercaptans, are useful for limiting sulfur-induced corrosion. Surface-modified particles incorporating a hexahydrotriazine moiety are disclosed and used as sulfur scavengers. These surface-modified particles are used a filter media in fixed filter systems and as additives to fluids including sulfur compounds. The hexahydrotriazine moiety can react with sulfur compounds in such a manner as to bind sulfur atoms to the surface-modified particles, thus allowing removal of the sulfur atoms from fluids such as crude oil, natural gas, hydrocarbon combustion exhaust gases, sulfur polluted air and water. The surface-modified particles may, in general, be sized to allow separation of the particles from the process fluid by sedimentation, size-exclusion filtration or the like.

摘要： The invention is classified as a physicochemical method of natural and waste water treatment and can be used in the energy engineering, chemical, petrochemical, food and other industries, especially in treatment of process, domestic, precipitation, mining, oilfield, quarry water and the water of tailing pounds.
The purpose of the invention is to improve the treatment of natural and waste water, to increase the capacity of a moving bed pressure filter and also to ensure high efficiency of the cleaning of the moving bed.
The technical result is the expansion of the range of application of the moving bed pressure filter ensuring high efficiency of treatment of both low-contaminated natural water and highly contaminated waste water.
This result is obtained due to the use of additional stages of chemical treatment during water treatment (oxidizing agent, demulsifier, powder sorbent), the use of various types of a pressure flocculation reactor, grains for a single and double moving bed, which have different grain composition and density, the performance of four-stage cleaning of the moving bed, the use of a dual-flow moving bed pressure filter, as well as due to the use of the additional pressure flocculation reactor followed by the removal of severe contamination with the use of a pressurized hydrocyclone.

摘要： A hybrid filtration sock comprises a mesh tube filled with a blended filler comprising 60%-90% fibrous volumizing filler and 10%-40% woody organic filler. The fibrous volumizing filler 12 includes straw, grasses, pine straw, corn stalks, natural fibers and weeds and combinations thereof. The woody organic filler is ground or chipped wood based material from land clearing, yard waste, pallets and clean wood debris or clean wood scraps, comprising a PH of between 5.0 and 8.0, with a particle size wherein 99% passes a 2 in (50 mm) sieve and a maximum of 43% passes a ⅜ in (9.5 mm) sieve, and
