Heat and mass transfer in spacer-filled direct contact membrane distillation were experimentally investigated explained more detail based on the combination of thin film theory boundary layer theory.Experimental results used to calculate coefficient through instead existing Sherwood number correlations or modeling results.Consequently, change (DCMD) performance terms fluxes, temperature polarization (TPC), concentration (CPC) could be analyzed clearly fluctuation layer, thickness.Moreover,...
Fishing with artificial light has become one of the most advanced, efficient, and common methods for night-time purse seining in Vietnam. This study evaluated radiation spectrum, CIE chromaticity coordinates, correlated color temperature (CCT), catch rate, fuel consumption, CO2 emissions when using Light emitting diode (LED) lamps (0.196 kW) comparison use metal halide (MH) lights (1 offshore seine fishery Quang Tri province, The fishing efficiency boats LED increased 1.58 times rate than MH...
Abstract Lead-free (K 0.48 Na Li 0.04 )(Nb 0.95 Sb 0.05 )O 3 (KNLNS) ceramics have been successfully optimized for the calcination and two-step sintering temperatures. The experimental results reveal that KNLNS powder calcined at 850 or 900 °C presented a pure perovskite phase with an orthorhombic phase. particle size was in range of 0.1–0.4 μ m. temperature (range: 950 to 1100 °C) significantly affects structure, microstructure, electrical properties ceramics. presence good crystallization...
Energy aspects and cost analysis in DCMD using different commercial PTFE membranes are experimentally examined under the impact of operating conditions membrane pore sizes.Regarding energy efficiency (EE), gain output ratio (GOR), specific consumption (SEC), feed inlet temperature is most influential factor comparison to concentration volume flow rate.Regarding size, system a larger had lower per cubic meter freshwater production than smaller membrane.
Abstract This paper presents an experimental investigation of heat transfer in direct contact membrane distillation (DCMD) flow channels with and without the spacer. In this experiment, usual hydrophobic DCMD is replaced by a copper plate to eliminate mass transfer. The study shows most appropriate correlations for empty channel cases different heights rates. For case spacer channels, two materials are investigated: nonwoven plastic woven stainless steel. correlation both these materials....
A protease-producing Stenotrophomonas rhizophila MT1 isolated from sludge samples of shrimp ponds was selected to evaluate extracellular proteases.Enzyme activity reached the highest value 139.02 U/mL after 60 h culture.The isolate produced protease in culture medium containing 1% casein (w/v) with an inoculum size 10% (v/v) and agitation speed 180 rpm.Zymography indicated two proteolytic bands estimated molecular weights 30 kDa 110 kDa, respectively.The increased Ca 2+ , Mg Co K + ions...
The antimicrobial activity of silver nanoparticles is widely known. However, their application to biodegradable polymeric materials still limited. In this work, we report a strategy involving the green synthesis nanocomposite films based on natural matrix. Nanometer-sized (C-AgNPs) were synthesized with aid ultrasound waves between nitrate solution and nanocurcumin solution. C-AgNPs found have particle sizes in range 5–25 nm demonstrated good against Clostridium perfringens, Staphylococcus...
The mass transfer mechanism within commercial PTFE membrane with various nominal pore sizes in spacer-filled direct contact distillation (DCMD) was determined. Mass fluxes and permeability (MP) values for each were experimentally measured. MP increased insignificantly 2.3% 4% when the inlet temperature at feed side rose from 400C to 500C different sizes. All investigated models except Dusty Gas model good enough simulate inside smaller (0.22 µm, 0.45 µm). Compared combined diffusion model,...
Lectins are carbohydrate-binding protein domains. The C-type lectin designates a requirement for calcium binding. Proteins contain domains that have diverse range of functions, including cell-cell adhesion, immune response to pathogens, and apoptosis. This study aimed investigate the characters LvCTL-encoding genes from white-leg shrimp (
This study aims to clarify the salinization degree of irrigation water in Quang Dien and Phu Vang districts Winter-Spring crop season propose a potential technology treat saline on lab-scale. The majority was brackish (70%) at Phuoc, Loi, villages with concentration up nearly 7.1‰. For Thai An villages, is much lower when percentage from 30% 40%. Direct contact membrane distillation (DCMD) implemented 20‰ - 40‰ concentrations water. experimental results revealed that freshwater production by...
Tóm tắt: Phân vùng chất lượng nước cho mục đích nuôi tôm ở đầm phá Tam Giang – Cầu Hai được tiến hành với sự hỗ trợ của công nghệ GIS. Mẫu thu 44 điểm trong mùa mưa và khô. Kết quả thấy các yếu tố nhiệt độ, pH, DO, độ mặn, kiềm, N–NH3 khô cao hơn mưa. Giá trị trung bình môi trường biến động qua như sau: 22,8–29,3 °C (nhiệt độ), 6,09–8,87 (pH), 3,76–8,25 mg/L (DO), 0,3–28,5‰ (độ mặn), 17,9–107 kiềm) 0,019–0,725 (N–NH3). Vùng diện tích có pH < 7, không phù hợp lấy tôm, chiếm 2,34% (mùa khô)...
