Patent number: 5944868Abstract: Ion exchange is used to make two grades of liquid fertilizer. In the first phase, ammonium thiosulfate (ATS) is contacted with a potassium-containing ion exchange resin to make the liquid fertilizer potassium thiosulfate (KTS) and an ammonium-containing resin.

Patent number: 4804401Abstract: A method for producing combined phosphorus fertilizer and soil conditioner in which phosphate rock and, as reaction matter, organic acidic matter are used. In a method according to the invention, the acidic mass is organic, for instance, bark waste, peat, waste fiber from a cellulose production plant or paper mill, sawdust or similar matter.Type: GrantFiled: October 17, 1986Date of Patent: February 14, 1989Inventors: Arvo Wahlberg, deceased, by Anna-Maija Wahlberg, legal representative

Patent number: 4792349Abstract: The present invention teaches a technique and provides for apparatus eminently useful for the econimic recovery of Fe, Zn, and S from waste galvinizer sulfuric acid and crystals of iron sulfate and zinc sulfate. The technique or method of the instant invention involves the ammoniation of the acid or a solution prepared from such crystals followed by the partial oxidation of the resulting ammoniated suspension to a point where the desired product magnetite is formed in the separated from a marketable solution of ammoniacal zinc sulfate. The effecting of the instant technique requires only a minimal amount of relatively inexpensive equipment and is simply and easily placed into practice by, for example, sparging anhydrous ammonia into a stirred tank of waste acid until the Ph is elevated to about 10. Air can be sparged through the resulting slurry to oxidize the iron in the acid. After a proper incubation period, the desired stable product, e.g.Type: GrantFiled: November 3, 1987Date of Patent: December 20, 1988Assignee: Tennessee Valley AuthorityInventors: Joe R.

Patent number: 4786308Abstract: The growth medium consists of a homogeneous mixture of short rockwool fibres, and short vegetable fibres, preferably peat fibres. Humus material may be added, preferably composted sludge. To the mixture may also be added fertilizer, and seeds, e.g. grass seeds being bound to said fibres by a rapidly disintegrating binder.The method for producing said growth medium comprises intimately mixing long rockwool fibres, and vegetable fibres, preferably peat fibres, and possible additional materials in a dry state in a mixer until homogenous spheres or balls are formed which contain the components in a substantially uniform mixture, and cutting said spheres into short fibres by the aid of beating knives, a hammer mill or the like, and then conveying said medium to the growing site or to a packaging by the aid of an air jet.Type: GrantFiled: June 2, 1987Date of Patent: November 22, 1988Inventor: Knut Colling

Patent number: 4716027Abstract: This invention relates to an apparatus and method for simultaneously scrubbing acidic exhaust gases and removing metal salts from alkaline waste dust from a cement plant or the like thereby producing useful products from what would otherwise be wasted. In essence the two wastes are combined in water and the resulting solution and precipitate separated in a tank. The solution is useful both to cool incoming waste gas and as a fertilizer, whilst the precipitate is suitable as kiln feed stock.Type: GrantFiled: September 5, 1986Date of Patent: December 29, 1987Assignee: Passamaquoddy Tribe, A Sovereign Indian tribe recognized by the Government of The United States of AmericaInventor: Garrett L. Morrison
