Membrane processes in nanoparticle production

EPDM Membrane Production: Materials and Manufacturing Processes

Because these reactive sites are pendant (not part of the main backbone chain) there are no weak points on the main chain. This is unlike for example Natural Rubber or SBR, where these necessary reactive sites are along the main chain. This means that reactive entities in the atmosphere (for example Ozone, which is very aggressive) can easily attack and degrade these materials. This also explai...

Physical Backwash Optimization in Membrane Filtration Processes: Seawater Ultrafiltration Case

Seawater ultrafi ltration (UF) as a pretreatment of reverse osmosis (RO) process in a thermal power plant was investigated using a 100 kDa hollow fi ber membrane. The choice of the UF physical backwash conditions remains arbitrary or ensuing from a sensibility study. As the optimum must take into account the factors interactions, we led a response surface study to analy...

Membrane processes in production of functional whey components

Whey, a valuable by-product of cheese manufacture, is the liquid fraction drained from the curd. Recently, the biological properties of individual whey constituents, such as a-lactalbumin (a-La) and b-lactoglobulin (b-Lg), lactoperoxidase (LP), lactoferrin (LF), glycomacropeptide (GMP) and immunoglobulins (IgGs), have become a focus of commercial interest as potential ingredients of so-called f...

performance of biological system and advanced oxidation processes (aop) treating antibiotic production industrial wastewater

در این مطالعه، عملکرد دو سیستم اکسیداسیون شیمیایی پیشرفته و یک سیستم بیولوژیکی برای حذف آموکسی سیلین در فاضلاب های سنتزیدر غلظت های مشابه با موارد صنعتی مورد بررسی قرار گرفته شدند. مطالعه انجام شده دارای سه بخش متفاوت اکسیداسیون با ازن و اشعه uv، اکسیداسیون با استفاده از نانو فتوکاتالیست tio2 و استفاده از بیوراکتور هوازی لجن فعال با جداکننده های فیزیکی می باشد. در هر بخش، متغیر های متفاوتی متنا...
