The treatment of tannery effluent is great interest as it contains a complex mixture pollutants, primarily chromium. disposal this wastewater can have adverse effects on the environment and aquatic life, which an emerging problem for environment. In work, electrocoagulation used to remove chromium from real wastewater, focusing performance optimization sludge characterization. Electrocoagulation experiments were conducted using electrochemical cell with iron electrodes immersed in specific...

Nickel has wide range of applications, and its production is expanding to meet the growing demand especially for energy storage applications. Hydrometallurgical nickel extraction from laterite ores requires a significant amount sulfuric acid, primarily due acid-consuming minerals such as magnesium silicates. The reaction acid silicates results in sulfate waste solution which an environmental liability. Electrochemical separation can be used produce these solutions reused on-site increase...

Alkali-earth metals pose a significant challenge to water treatment technologies and electrochemical processes due their propensity precipitate as metal hydroxides, which can deposit on membranes and/or electrodes reduce efficiencies. Membraneless electrolyzers partially overcome this issue because they lack or diaphragms, however are still susceptible fouling. To issue, be incorporated into recirculating electrolyte scheme where magnesium is removed in the form of Mg(OH)2 before reaching...

The intense colour of the spent wash effluent leads to crucial ecological issue when released untreated into environment. decolourization distillery is known be a very challenging task. In this study, degradation organic pollutants in form was performed using nano photocatalyst prepared aluminium oxide (Al2O3) nanoparticle and kaolin clay. As-synthesized nano-Al2O3/kaolin composites were used as for effluent. process parameters such dosage, pH, temperature agitation optimized attain maximum...

Data-driven models are essential tools for the development of surrogate that can be used design, operation, and optimization industrial processes. One approach developing is through use input–output data obtained from a process simulator. To enhance model robustness, proper sampling techniques required to cover entire domain variables uniformly. In present work, Monte Carlo with pseudo-random samples as well Latin hypercube quasi-Monte Hammersley Sequence Sampling (HSS) generated. The...

Steelmaking is an energy-intensive process that generates considerable amounts of by-products and wastes, which often pose major environmental economic challenges to the steel-making industry. One these steel dust produced during separation impurities in smelting refining metals furnaces. In this study, electric arc furnace (EAF) has been evaluated as a potential, low-cost additive increase viscosity weight drilling muds. Currently, cost operations typically accounts for 50 80% exploration...

In New York City, traffic crashes are one of the main causes fatalities in city. This study presents a comprehensive time series analysis road city from 2013 to 2019. The crash data were collected, organized, and analyzed at different levels: yearly, seasonally, monthly hourly bases. Forecasting total number years 2020 2025 was conducted using Box-Jenkins method based on autoregressive integrated moving average (ARIMA) model. model statistically validated modified Box-Pierce (Ljung-Box)...
