Characteristics and Gel Properties of Gelatin from Goat Skin as Influenced by Alkaline-pretreatment Conditions
Goat Gelatin Skin Pretreatment Alkaline Gel Strength
2016/6/27
Characteristics and properties of gelatin from goat skin pretreated with NaOH solutions (0.50 and 0.75 M) for various times (1 to 4 days) were investigated. All gelatins contained α-chains as the pred...
Study of Backwashing Process for Ceramic Micro-Filtration Membranes Used in Pretreatment of DMF Wastewater
Backwashing Process Ceramic Micro-Filtration Membrane DMF Wastewater Membrane Fouling
2011/12/1
DMF wastewater from the PU synthetic leather industries was filtrated by ZrO2 micro-filtration membranes with an average pore size of 0.2μm. The membrane fouling mechanism was analyzed by resistance-i...
