Sažetak
Poultry farming and production is one of very important branches of the food and food processing industry, which produces important foodstuffs, semi-fi nished products and by-products for further processing. Intense processing of the poultry products results in a massive formation of the heavily polluted wastewaters containing many hazardous pollutants. This problem is very acute for many countries where this branch is quick-growing and being under extended investigation of various decontamination methods of the poultry processing wastewaters. Poultry feather is not involved in any food processing industry but can be used as an adsorbent or fi ller for some clothes and bed clothes. Relevant industrial
feather-processing stages also produce some contaminated wastewaters and a problem of their decontamination is still beyond systematic analysis and investigation. This paper deals with analysis of the poultry feather-processing wastewaters composition and experimental investigation of various methods and technologies of their decontamination. Iron chloride combined with polyacrylamide ensured the best wastewater cleaning/fl occulation activity and a combined wastewater treatment scheme with primary cleaning/fl occulation, secondary complex biotreatment and tertiary sand-fi ltration has been proposed in order to reach a required decontamination depth. This technology proves the wastewater quality, which complies with the offi cially set limits.
