Вторичная переработка рыбьей чешуи выполнена на кафедре химии Калининградского государственного технического университета экономически доступным способом. Чешую отмывали водой с добавлением NaCl и Na2CO3 при нагревании. Центрифугирование при 2347 RCF, сушка и отсев на ситах позволили получить коллагеновое волокно разных фракций. Описан процесс получения коллагенового фильтра, указаны его характеристики. Приведены результаты полевого эксперимента по фильтрации воды из городского водотока Калининграда исследуемым сорбционным фильтром. Проведен сравнительный анализ органолептических и физико-химических показателей исследуемого образца воды до и после фильтрации. Адсорбционная способность оценивалась по нескольким параметрам. Анализ фильтрата показал, что происходит осаждение ионов Na+, SO42-, Cl-, НСО3-; биoгенных элементов в молекулярном и ионном виде SiО2, NH4+, NO3-, снижается общая минерализация более чем в 3 раза. Значительно улучшились органолептические показатели отфильтрованной воды – прозрачность, цвет и запах. Полученные данные приведены в сравнении с водной средой, взятой из водотока г. Калининграда. Выявлены селективные свойства коллагенового фильтра. Показано, что использование коллагенового волокна эффективно для очистки водных сред и может быть рекомендовано для создания биоразлагаемых фильтров жидких фракций. Методологическим успехом является обоснование возможности использования природного вторичного сырья для снижения экологических проблем хранения и переработки фибриллярных белков чешуи гидробионтов.</p></abstract><trans-abstract xml:lang="en"><p>The article is devoted to the study of the prospects for using biodegradable collagen fiber as a sorbent. Recycling of fish scales has been carried out at the Department of Chemistry of Kaliningrad State Technical University, in an economically accessible way. The scales were washed with water with the addition of NaCl and Na2CO3 while heating. Centrifugation at 2347 RCF, drying and screening on sieves made it possible to obtain new collagen fiber of different fractions. The process of obtaining a collagen filter is described and its characteristics are indicated. The results of a field experiment on the filtration of water from an urban watercourse in Kaliningrad using the sorption filter under study are presented. A comparative analysis of the organoleptic and physicochemical parameters of the studied water sample before and after filtration has been carried out. Adsorption capacity has been assessed using several parameters. Analysis of the filtrate showed that precipitation of ions occurs Na+, SO42-, Cl-, HCO3-; biogenic elements in molecular and ionic form SiO2, NH4+, NO3-, total mineralization decreases by more than 3 times. The organoleptic characteristics of filtered water have significantly improved: transparency, color and smell. The obtained data are presented in comparison with the aquatic environment taken from the Kaliningrad watercourse. The selective properties of the collagen filter have been revealed. It has been shown that the use of collagen fiber is effective for purifying aqueous media and can be recommended for creating biodegradable filters for liquid fractions. A methodological success is the substantiation of the possibility of using natural secondary raw materials to reduce the environmental problems of storing and processing fibrillar proteins of hydrobiont scales.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биоразлагаемое волокно</kwd><kwd>чешуя гидробионтов</kwd><kwd>фильтрующий элемент</kwd><kwd>сорбент</kwd><kwd>очистка воды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>biodegradable fiber</kwd><kwd>scales of hydrobionts</kwd><kwd>filter element</kwd><kwd>sorbent</kwd><kwd>water purification</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Recycling and use fibrous waste in industrial production / B.
