Evaluating the Sintering Temperature Control Towards the Adsorptivity of Ammonia onto the Natural Zeolite Based Hollow Fibre Ceramic Membrane
The disproportionate quantity of ammonia presence in water has led to serious drinkable water scarcity worldwide. The abundant source of mineral and superior cations selectivity has made natural zeolite as a good adsorbent for the ammonia removal. This work aims to fabricate natural zeolite based hollow fibre ceramic membrane (HFCM) via extrusion based phase inversion and sintering techniques f...
متن کاملDigestive alkaline proteases from the Tunisian barbell (Barbus callensis): Characterization and application as a detergent additive, in chicken feather-degradation and as a dehairing agent
Alkaline crude enzymes from the viscera of the Tunisian barbel (Barbus callensis) were extracted and characterized. Proteolytic crude extract from barbel viscera was active and stable in alkaline solution. The optimum pH and temperature were 11.0 and 55 °C, respectively, using casein as a substrate. The crude alkaline protease was extremely stable in the pH range of 5.0-12.0. Zymography activit...
متن کاملبررسی کارایی فرایند آنزیمی هورس رادیش پراکسیداز (HRP) و آب اکسیژنه در حذف آلکیل بنزیل سولفونات خطی (LAS) از محیط های آبی
Background and purpose: Enzymatic treatment, due to various benefits, has attracted many researchers since long time ago. Anionic detergents are one of the largest families of detergents that entered into the environment in recent decades. This study investigated the effect of horseradish peroxidase enzyme process on the removal of linear alkaline benzyl sulfonate (LAS) from aqueous solutions. ...

متن کاملبررسی کارایی فرایند پلیمریزاسیون آنزیمی در حذف فنل از فاضلاب مصنوعی
Background and Objectives: Phenolic compounds are presence in many industrial wastewaters, and have been classified as priority pollutants. Application of several conventional processes due to high cost and low efficiency has been limited. Thus, new methods such as enzymatic polymerization seem to be preferable and effective processes with high potential to substitute the conventional processes...
