15 صفحه اولinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Improved Solid-liquid Separations with Temperature Responsive Flocculants: a Review
Recent progress in the development of temperature responsive flocculants based on poly (N-isopropyl acrylamide) (PNIPAM) is reviewed. The polymer switches between a flocculant at temperature above the Lower Critical Solution Temperature (LCST) (32C for PNIPAM) and a dispersant at temperature below the LCST. Both batch sedimentation and continuous pilot scale operations have been conducted. Sedi...
متن کاملEnhanced solid-liquid separation of dairy manure with natural flocculants.
The aim of this study was to determine the effectiveness of natural flocculants to reduce solids and nutrient loads in dairy cow wastewater using solid-liquid separation; chitosan was used as a model. Its use efficiency and optimum application rate were determined using flushed dairy cow manure of varied strengths - 0.4%, 0.8%, 1.6%, and 3.2% total solids (TS) content. Treatments consisted of n...
