METHOD FOR RECOVERING PHOSPHORUS FROM SLUDGE RICH IN CHEMICAL PHOSPHORUS PRECIPITATES USING HIGH-PROTEIN BIOMASS WASTE

Disclosed is a method for recovering phosphorus from sludge rich in chemical phosphorus precipitates using a high-protein biomass waste, comprising introducing the sludge rich in chemical phosphorus precipitates into an anaerobic fermenter, adding a certain amount of a high-protein biomass by-product, sealing the fermenter and fermenting for 4-7 days. The method can effectively increase the phosphorus release efficiency from the sludge, and also generate volatile short-chain fatty acids and ammonia nitrogen in high concentrations. After dewatering, phosphorus and part of ammonia nitrogen can be recovered in a form of high-purity struvite crystals only by addition of a magnesium salt and adjustment of pH to 7.5-9.0. The volatile short-chain fatty acids can be used as an economical carbon source. The method allows simultaneous utilization of two solid wastes to recover carbon, nitrogen and phosphorus resources, and can reduce the usage of chemical reagents, saving the treatment cost.

Humidifier for skin-divers compressed air supply - draws moisture via tiny perforations from water-loaded absorbent matl.

A humidifier is claimed for the air, or other respiratory gas, which is supplied to a skin-diver, via a pressure-reducing valve from this high pressure cylinder. The humidifier, which is fitted in the line between the reducing valve and the diver's mouthpiece, comprises a container in which a water-loaded mass of absorbent material communicates with an air passage only via very small perforations, e.g. about 3-6 mm dia, such that surface tension prevents free flow through the perforations but allows them to fill with water drawn from the absorbent material as the diver inhales.

Cyclic process for wet-chemically producing lithium metal phosphates

The invention relates to a method for producing lithium metal phosphates of a formula LiMPO4, wherein M is at least one type of bivalent metal, preferably selected from the first transition metal range. The inventive method consists in reacting a lithium phosphate with a metal salt and an acid phosphate source in a polar solvent for converting into a corresponding M-containing phosphate, in adding a basic lithium source for obtaining a precursor mixture for a desired lithium metal phosphate, in converting and separating the thus obtained mixture, preferably in hydrothermal conditions, in such a way that a desired final product is obtained, thereby receiving a lithium-containing filtrate. The addition of the basic lithium source initiates a lithium ion precipitation in the form of a lithium phosphate. The thus obtainable lithium phosphate can be reused in the form of a raw material, whereby said cycle enables lithium to be highly reusable.

Improvements in or relating to production of radioactive phosphorus

765,489. Purifying radio-isotopes. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Sept. 26, 1955 [Sept. 25, 1954], No. 27760/54. Class 39(4). Radioactive phosphorus is obtained from neutron irradiated sulphur by distilling off the sulphur and taking up the residue with a mineral acid. After irradiation in a flux of 10<12> neutrons/square centimetre per second for 28 days with the sulphur in a silica vessel, the sulphur is distilled off at about 500‹C. in the presence of nitrogen. The sulphur thus increases in purity and may be further irradiated. The phosphorus is removed as phosphoric acid with hydrochloric acid containing some hydrogen peroxide. The specification also describes the recovery of phosphorus-by oxidation with nitric acid and treating with iron or lanthanum.

Improvements in or relating to the manufacture of phosphorus or phosphorus pentoxide

In obtaining phosphorus or phosphorus pentoxide, briquettes of comingled phosphorus containing mineral and carbonaceous material are charged into a furnace together with separately charged additional silicious material and, if desired, further carbonaceous material, phosphorus being volatilized, and also oxidized if desired, and a slag being produced. The briquettes may contain some silicious material, but the quantity must be insufficient to form a suitable slag without the introduction of the additional silica. The total amount of silica present should be sufficient to provide a ratio of 0,6 to 1,2 parts of silica to one part of calcium oxide. In making the briquettes, binders such as sulphate liquor or molasses may be employed. The carbonaceous material in the briquettes may comprise coke, anthracite, or bituminous coal and should preferably be in at least sufficient quantity for the reduction of the phosphorus in the mineral. Phosphate rock may be employed as raw phosphorus containing material and pebble silica, clay or other silicates as the silicious material.
