چکیده در تصفیه آب و واحدهای نمک زدایی با استفاده از غشاهای اسمز معکوس (ro) و نانوفیلتر (nf)، گرفتگی غشایی مشکلی جدی محسوب می شود. یکی از دلایل اصلی گرفتگی غشایی در ro و nf رسوب مواد معلق و کلوئیدی موجود در آب خوراک در طول فیلتراسیون است که گرفتگی ذرات معلق یا گرفتگی کلوئیدی نامیده می شود. ذرات کلوئیدی موجود در آب خوراک غشاهای اسمز معکوس و نانوفیلتر تمایل دارند در فضاهای خالی و روی سطح غشا رس...

Reverse osmosis (RO) technology has been widely applied to water treatment such as seawater desalination, and large RO plants are many in operation around the world. Moreover, much larger plants will be required to secure sufcient water resource in the near future because global water shortage and quality problems are still getting more serious. Mega-ton Water System pr...

In this study we introduce the concepts of statistical convergence of order$beta$ and strong $p-$Ces`{a}ro summability of order $beta$ for sequencesof fuzzy numbers. Also, we give some relations between the statisticalconvergence of order $beta$ and strong $p-$Ces`{a}ro summability of order$beta$ and construct some interesting examples.

This paper investigates the simulation of a hybrid desalination system composed of multi-effect evaporation with thermal vapour compression desalination (METVC) and reverse osmosis (RO) plant. The hybrid desalination system is also integrated with a gas turbine power plant through a heat recovery steam generator (HRSG). First, a comprehensive Thermodynamic model for HRSG, METVC, and RO are deve...
