[Operation of systems for purification of sewage and surface waters based on sorption-oxidative technology].

A universal scheme for the treatment of water containing different concentrations of organic compounds is described. The treatment is based on the principle of the water saturation with an active oxidant followed by aerobic purification in units with microflora fixed on active carbon. Active chlorine forming during the electrochemical treatment provides the water disinfection and plays the role of a source of the formation of monatomic and molecular oxygen during the dechlorination.

[Use of mycelial waste products as an additive in the manufacture of granulated active carbon].

The physico-chemical characteristics of type MAU active carbon manufactured with the use of the mycelial waste of tetracycline production and carbon residue are presented. Granulated active carbon MAU-5 was tested under laboratory conditions at the stage of the treatment of the antibiotic production waste. For the manufacture of the granulated active carbon the mycelial waste with the moisture content of 8 per cent and the carbon residue of weared tyres were used.

[The possibility for obtaining sorbents from the mycelial wastes of antibiotic production].

A technological process for production of a sorbent based on the mycelial waste of penicillin manufacture was developed. The process and its parameters are described. The exploitation conditions determine whether a strong sorbent with low sorption properties or a sorbent with higher sorption properties and lower granule strength is prepared.

[The technology of sewage purification and water treatment in self-contained oxidation-biosorption units].

A technological process for oxybiosorption of sewage was developed. The process and a self-contained unit using it are described.
