چکیده

تأمین آب آشامیدنی در بخش مصرف خانگی به‌دلیل اثربخشی مستقیم بر سلامت انسان همواره مورد تأکید بوده است. یکی از روش­های رایج برای کاهش آلاینده­های جامد محلول که در بسیاری از مناطق کشور به‌کار می‌رود، استفاده از دستگاه­های تصفیه‌کنندۀ آب خانگی است. باوجود مصرفی بودن پالایه‌های این دستگاه­ها کهدر بازه­های زمانی مشخصی تعویض می‌شود، با توجه به سازوکار عمل‌کردشان که مبتنی بر اسمزمعکوس است، 70-80% از آب لوله‌کشی را با انتقال به پساب هدر می­دهند. در مقابل، سامانه­های تقطیر خورشیدی وجود دارد که با استفاده از انرژی خورشیدی، آب مقطر تولید می­کنند. سامانه­های تقطیر خورشیدی به‌دلیل جلوگیری از هدررفت آب، استفادۀ آسان و طول عمر زیاد، توان بالایی برای تأمین آب آشامیدنی با کیفیت برای نواحی با جمعیت اندک و آب و هوای گرم دارند. بررسی فنی و اقتصادی استفاده از دستگاه­های تصفیۀ آب خانگی و سامانۀ تقطیر خورشیدی برای دستیابی به آبی با کیفیت و قابل آشامیدن در منازل و هم‌چنین بررسی تجزیۀ حساسیت هزینۀ آب، هزینۀ عملیاتی و افزایش هزینۀ ثابت اولیه، هدف این پژوهش است. نتایج نشان می‌دهد که باوجود هزینۀ اولیۀ بالاتر سامانۀ تقطیر خورشیدی، هزینۀ استفاده از این سامانه در درازمدت از نظر اقتصادی به‌صرفه‌تر است، ضمن آن‌که کاستی ِهدررفت آب نیز در این سامانه‌­ها وجود ندارد.

چکیده [English]

Drinking water supply in the household consumption sector has always been emphasized due to its direct impact on human health. One of the common methods to reduce soluble solid pollutants that is used in many parts of the country, is the use of household water purifiers. Despite the usefulness of filters in these devices which need to be replaced at regular intervals, they waste 70-80% of piped water by transferring it to sewage due to their mechanism of action based on reverse osmosis. In contrast, there are solar distillation systems that produce distilled water using solar energy. The use of solar distillation systems has a high potential to provide quality drinking water for sparsely populated areas and hot weather due to its prevention of water loss, easy use and long life. The purpose of this research was to Techno-economic study the use of household water purifiers and solar distillation system to achieve quality and potable water in homes, as well as to analyze the sensitivity of water cost, operating cost and increase the initial fixed cost. The results show that despite the higher initial cost of the solar distillation system, the cost of using these systems in the long run is more economical, and the water loss for these systems can be ignored.
