چکیده

در این پژوهش، ابتدا فرایند تصفیه آب توسط هیبرید غشای اسمز مستقیم و اولترافیلتراسیون مدل‌سازی شد، سپس این سیستم از نظر کنترل کیفیت و هزینه‌ها با نتایج تجربی مقایسه شد. در فرایند اسمز مستقیم از محلول پلی آکریلات سدیم بسیار غلیظ به‌عنوان محلول کشنده استفاده شد. هنگامی که طرف FO غشای هیبریدی با فاضلاب، آب دریا یا آب شور تماس پیدا می‌کند، آب تمیز از طریق غشای FO در حدود 1 گرم  به محلول SPAA کشیده می‌شود. سپس آب تمیز از محلول SPAA از طریق غشای UF با اعمال فشار، که می‌تواند هیدرولیکی یا مکانیکی کمتر از bar 1 باشد، خارج می‌شود. مدل‌سازی برای اثبات اعتبار مفهوم طراحی انجام شد. برخی از معادلات مدل برای شبیه‌سازی عملکرد غشای هیبریدی استخراج شد و داده‌های تجربی بر اساس معادلات مدل، تجزیه‌و‌تحلیل شد. هدف بر این است که این روش اجازه تولید آب با کیفیت RO را در فشار UF بسیار کمتر از فشارRO ‌دهد و بنابراین منجر به کاهش قابل توجه مصرف انرژی برای تولید آب شود. روندی مشاهده شد که وقتی
CSPA,0 کمتر از 75/15 درصد وزنی بود، آب بیشتری (از مقدار محاسبه‌ شده) توانست به محلول SPAA کشیده شود، در حالی که وقتی CSPA,0 بیش از 75/15 درصد وزنی بود، آب کمتری کشیده شد.

چکیده [English]

In this study, first, the water purification process was modeled by the hybrid of direct osmosis membrane and ultrafiltration, then the current system was compared with experimental results in terms of quality control and costs. In the direct osmosis process, a highly concentrated sodium polyacrylate solution was used as the draw solution. When the FO side of the hybrid membrane met wastewater, seawater, or saltwater, clean water was drawn through the FO membrane into the SPA solution. Then, the clean water was removed from the SPA solution through the UF membrane by applying pressure, which can be hydraulic or mechanical, less than 1 bar. Modeling was done to prove the validity of the design concept. Some model equations were extracted to simulate the performance of the hybrid membrane, and the experimental data were analyzed based on the model equations. It is believed that this method allows the production of RO quality water at a UF pressure much lower than the RO pressure and thus leads to a significant reduction in energy consumption for water production. It was noticed that more water (than the calculated value) could be drawn to the SPA solution when the CSPA,0 was<15.75 wt% while less water was drawn when CSPA,0 was>15.75 wt%.
