Description

Tak wytworzone filtry maja zastosowanie szcze¬ gólnie do oczyszczania wody uzywanej przez duze skupiska ludzi, korzystajacych z tego samego zró- 5315153151 3 dla. Ma to miedzy innymi miejsce na wszelkiego rodzaju plywajacych obiektach morskich.Przyklad Z mieszaniny o skladzie: Glina szlamowana — 25% Humus — 30% Stluczka szklana biala — 5°/o Ziemia krzemionkowa o uziarnieniu 0,1—0,6 mm — 40% przygotowanej opisanym wyzej sposobem, for¬ muje sie filtry, nastepnie suszy sie je w tempe¬ raturze 110°C i potem wypala w temperaturze 1100°C.Wypalone filtry nasyca sie 1,2%-owym roztwo¬ rem azotanu srebra w czasie 5 godzin, a nastep¬ nie wytraca sie chlorek srebra w porach filtrów przez zanurzenie ich w kapieli 10%-owego kwasu solnego przez okres 20 godzin. PLThe filters thus produced are particularly applicable to the purification of water used by large groups of people using the same variation for. This is the case, among others, for all kinds of floating marine objects. Example A mixture composed of: Sludge clay - 25% Humus - 30% White glass cullet - 5% / o Siliceous earth, grain size 0.1-0.6 mm - 40% prepared by the above-described method, the filters are formed, then they are dried at 110 ° C and then fired at 1100 ° C. The fired filters are saturated with 1.2% silver nitrate solution for 5 hours. and then the silver chloride is precipitated in the pores of the filters by immersing them in a bath of 10% hydrochloric acid for a period of 20 hours.

Claims

Claim 1. A method of producing ceramic filters for the purification of liquid substances, especially water, from suspensions and bacteria, characterized in that a mixture consisting of clay slurried in an amount of 20-40%, humus in an amount of 20- 40% and glass cullets in the amount of 2-8%, with the grain size of these components below 60 ° C and of siliceous earth calcined at 600-800 ° C with a grain size of 0.1-0.6 mm in the amount of 30-50 % is formed into a filter which, after drying at 110 ° C., is burnt at 1000 ° to 1200 ° C., and then saturated with a 1-3% solution of silver nitrate in such an amount that when lost, with a solution of hydrochloric acid, silver chloride, obtain it in an amount of 0.5-2% by weight in relation to the weight of the filter.
