Environmental Footprint of Inland Fisheries: Integrating LCA Analysis to Assess the Potential of Wastewater-Based Microalga Cultivation as a Promising Solution for Animal Feed Production
(Processes, 2023-11-20)
This study evaluated the environmental impacts of producing 1 kg of biomass for animal
feed grown in inland fisheries effluents as a culture medium using the ReCiPe method. Four scenarios
with two downstream alternatives ...
Sensitivity analysis and multi-objective optimization of the energy, exergy and thermo-economic performance of a Brayton supercritical CO2-ORC configurations
(Energy Reports, 2023-03-25)
The following research compared some energy, exergetic and thermo-economic indicators of a
supercritical CO2 simple Brayton cycle integrated with a simple organic Rankine cycle (SORC), and a
regenerative organic Rankine ...
Evaluation of Local Scour along the Base of Longitudinal Training Walls
(Bommanna Krishnappan, 2023-11-17)
This study proposes a new empirical model for estimating local scour along the base
of longitudinal training walls for granular riverbeds. The model’s performance was rigorously
assessed through experiments conducted in ...
A Phytochemical Approach to the Removal of Contaminants from Industrial Dyeing Wastewater
(ChemEngineering, 2023-09-28)
This study investigates the influence of photoperiod and wastewater concentration on the
growth of microalgae and cyanobacteria for the removal of environmentally significant parameters
(COD, BOD, Cr, Fe, color, chlorides, ...

Energy and exergetic performance analysis of a hybrid solar multi-stage Brayton cycle with different working fluids
(International Journal of Thermofluids, 2023-08-10)
An energy and exergy model for a hybrid multi-stage Brayton cycle solar thermal plant is presented, incorporating an arbitrary number of compression stages with intermediate cooling and expansion with reheating. In hybrid ...
Analysis of a three-dimensional numerical modeling approach for predicting scour processes in longitudinal walls of granular bedding rivers
(EUREKA: Physics and Engineering, 2023-07-27)
In rivers, longitudinal walls are protective structures that are directly supported on the riverbank are frequently used as hydraulic prevent the current from eroding the bank and causing scouring. However, these structures ...
Using the Response Surface Methodology to Treat Tannery Wastewater with the Bicarbonate-Peroxide System
(ChemEngineering, 2023-07-16)
A bicarbonate-peroxide (BAP) system was evaluated to improve the quality of industrial tannery wastewater using an I-optimal experimental design with four variables (temperature, initial pH, bicarbonate, and H2O2 concentration). ...
