Over the years, treatment of tannery waste-Water put a considerableburden on the total cost of production, be it pickled, in wet-blue, crust orfinished leather. After 1980 a very stringent regulation has been imposed on thequality and purity of the waste ... see more

This study investigated the feasibility of using acid activated carbon prepared from brewery spent barley husks for the adsorption of cadmium from aqueous solution. The effects of operation parameters such as pH, contact time, adsorbent dosage, concentrat... see more

The study reports results of experimental studies into processing highly concentrated metal-containing wastes (HCMW) from galvanic production with obtaining precipitates of the predefined chemical composition, specified physical-and-chemical properties an... see more

Conclusions. It was demonstrated that for highly concentrated waste effluents of a distillery (grain distillery spent wash), which after co-fermentation with poultry manure contain volatile fatty acids in concentration 800–2000 mg/dm3, it is needed to use... see more

Brewers' spent grains are the main residue generated from the brewery industry; they are produced on a large scale and at a low cost. During the brewing process, approximately 85% of all barley used is transformed into solid residue, which is currently de... see more

The aim of the research is to improve the technological scheme of treatment of iron-containing wastewater from etching operations by creating combined systems, including reagent wastewater treatment, their mutual neutralization, regeneration of etching so... see more

Context. Effective solution of a number of application problems related to transportation, as a rule, depends on the solution of two problems: the correct formation of the composition of the column of technique and the successful choice of the route of it... see more

Special features in the process of determining the coordinates of sound anomalies according to the sound series were considered. Sound anomalies have been shown to be a source of information about events, phenomena that are already occurring, or are their... see more

The crude dye extracted from the heartwood of Ceasalpinia sappan Linn. was reacted with alum to form a solution containing a cationic dye complex of [Al(brazilien)2]+ and used for the dyeing of silk yarn. The dye solution left after dyeing was treated wit... see more
