Description

Torfy wlókniste zawieraja w sobie znaczne ilosci kwasów humusowych, nie¬ rozpuszczalnych w wodzie. Kwasy tej grupy jako to krenowy, apokrenowy i ulminowy tworza z wapnem i zelazem sole nierozpuszczalne.Równiez nierozpuszczalnemi sa sole wapienno - potasowe kwasów humuso¬ wych. Dzieki temu torf nadaje sie zna¬ komicie, jako doskonaly materjal filtra¬ cyjny, celem uwolnienia wody, np. ko¬ tlowej, lub innych cieczy od rozpusz¬ czalnych zwiazków wapnia, zelaza i po¬ tasu. W szczególnosci donioslem bedzie zastosowanie metody oczyszczania ply¬ nów przez torf w przemysle cukrowni¬ czym. Oprócz wskazanego dzialania, torf, jako materjal wlóknisty i zawierajacy koloidy organiczne, sam juz przez sie znakomicie wydziela mety z wody lub innych plynów, tudziez odwania i od¬ barwia je.Preparowanie torfu do celów filtra¬ cyjnych odbywa sie w ten sposób, ze torf surowy wygotowuje sie w wodzie, albo tez w specjalnych naczyniach, pod¬ daje dzialaniu pary wodnej o wysokiej lub niskiej preznosci, póczem produkt wytlacza sie dla usuniecia z niego wy¬ waru i wylugowuje w strumieniu wody.Dla niektórych celów,, wzgl. oczyszcza¬ nia pewnych plynów jest rzecza wska¬ zana poddac jeszcze torf przed lugowa¬ niem woda dzialaniu czynników anty- septycznych, jak np. nadmanganianu potasu, formaliny,* chloru, ozonu, wody utlenionej lub. t. p. PLFiber peat contains significant amounts of water-insoluble humic acids. Acids of this group, as kernic, apocrenic and ulmic, form with lime and iron insoluble salts. The calcium-potassium salts of humic acids are also insoluble. As a result, peat is excellent as an excellent filter material for the release of water, for example charcoal, or other liquids from soluble calcium, iron and potassium compounds. In particular, the use of the peat-based fluid purification method in the sugar industry will be reported. In addition to the indicated effect, peat, as a fibrous material and containing organic colloids, already perfectly separates the fines from water or other liquids, and also detaches and discolor them. Peat is prepared for filtration purposes in such a way that the peat the raw product is boiled in water, or in special vessels, is subjected to the action of high or low pressure steam, then the product is extruded to remove the tear from it and leached out in a stream of water. In the treatment of certain liquids, it is advisable to treat the peat with antiseptic agents, such as, for example, potassium permanganate, formalin, chlorine, ozone, hydrogen peroxide or hydrogen peroxide before leaching the water. t. p.

Claims

Patent claims. 1. A method of purifying water or other liquids, characterized by the fact that the liquid is filtered through prepared peat.

2. The method of preparation of peat for filtration purposes, characterized by the fact that the raw peat is boiled in water or subjected to steam in special vessels under high or low pressure, then the product obtained is pressed and leached to remove the decoction zen and washed in a stream water.

3. The method of preparation of peat according to claim 2, characterized in that in some cases the peat, after it has been prepared, is subjected to the additional action of antiseptics. KOSIANSKI GRAPHICS DEPARTMENT IN WARSAW PL
