Xomashyo sifatida ishlatilgan alyuminiy saqlovchi adsorbentlarga natriy gidroksid va xlorid kislotasi eritmalari bilan nazorat ostidagi harorat rejimida kimyoviy ishlov berildi. Sintez natijasida faol alyumo-oksixlorid fazasi hosil bo‘ldi, bu termogravimetrik, differensial-termik va mikrotuzilma tahlillari bilan tasdiqlandi. Olingan koagulyant bir jinsli mikrotu-
zilma va barqaror fazaviy tarkibga ega bo‘lib, koagulyatsiya jarayonlarida yuqori samaradorlikni ta’minlaydi. Polialyuminiyxloridning optimal dozasi taxminan 1,25 g/dm³ ni tashkil etadi, biroq u boshlang‘ich suv tarkibiga, xususan, suspenziya zarrachalari konsentratsiyasi va pH qiymatiga bog‘liq. Optimal sharoitlarda tozalash natijasida 95 %gacha suspenziya zarrachalari olib tashlanadi. Ishlab chiqilgan texnologiya barqarorligi va iqtisodiy maqsadga muvofiqligi bilan ajralib turadi hamda alyuminiy saqlovchi chiqindilarni qayta ishlash imkonini beradi. Olingan natijalar mahalliy polialyuminiyxloridni tabiiy va oqava suvlarni tozalashda qo‘llash istiqbolliligini tasdiqlaydi. Texnologiya barqarorligi, ekologik maqsadga muvofiqligi va suv tayyorlash korxonalari uchun import o‘rnini bosish salohiyati bilan tavsiflanadi.
Проведены исследования по получению и оценке эффективности полиалюминийхлорида (ПАХ), синтезированного из алюмосодержащих отходов нефтегазовой промышленности, в коагуляции природных и сточных вод. В качестве сырья использованы отработанные алюмосодержащие адсорбенты, подвергавшиеся химической обработке растворами гидроксида натрия и соляной кислоты при контролируемых температурных условиях. В результате синтеза образуется активная алюмооксихлоридная фаза, что подтверждено данными термогравиметрического, дифференциально-термического и микроструктурного анализа. Установлено, что полученный коагулянт обладает однородной микроструктурой и устойчивым фазовым составом, обеспечивающими высокую эффективность в процессах коагуляции. Оптимальная доза полиалюминийхлорида составляет около 1,25 г/дм³, однако она зависит от состава исходной воды, в частности от концентрации взвешенных веществ и значения pH. При соблюдении
оптимальных условий обработки обеспечивается удаление до 95 % взвешенных частиц. Разработанная технология отличается технологической устойчивостью и экономической целесообразностью, а также способствует утилизации алюмосодержащих отходов нефтегазового производства. Полученные результаты подтверждают перспективность применения отечественного полиалюминийхлорида для очистки природных и сточных вод и решения актуальных экологических задач. Технология характеризуется устойчивостью, экологической целесообразностью и потенциалом импортозамещения для предприятий водоподготовки.

Studies were carried out to obtain and evaluate the efficiency of polyaluminumchloride synthesized from aluminum-containing wastes of the oil and gas industry for coagulation of natural and wastewater. Spent aluminum-
based adsorbents were used as raw materials; they were chemically treated with sodium hydroxide and hydrochloric acid solutions under controlled temperature conditions. As a result of the synthesis, an active alumino-
oxychloride phase was formed, which was confirmed by thermogravimetric, differential thermal, and microstructural analyses. It was established that the obtained coagulant has a homogeneous microstructure and a stable phase
composition, ensuring high efficiency in coagulation processes. The optimal dose of polyaluminumchloride is approximately 1.25 g/dm³; however, it varies depending on the composition of the source water, particularly the
concentration of suspended solids and the pH value. Under optimal treatment conditions, up to 95% of suspended particles can be removed. The developed technology is characterized by technological stability and economic feasibility, and it also contributes to the utilization of aluminum-containing wastes from oil and gas production. The findings confirm the potential of domestically produced polyaluminumchloride for the purification of natural and wastewater and for addressing important environmental challenges. The technology demonstrates operational stability, environmental viability, and import-substitution potential for water treatment enterprises.
