In this work, we proposed and tested a method for utilizing agricultural waste alum sludge as an effective adsorbent to treat poultry wastewater. The product was also targeted be used fertilizer agriculture. Modified biochar produced from crop residues, water treatment plant, magnesium salt. characterized by scanning electron microscopy, energy-dispersive X-ray spectroscopy, Brunauer-Emmett-Tel...

We used the software Optferm to model and optimize the bioprocess of escherichia coli fermentation, simulating the conditions of a fed-batch bioreactor. The results, obtained by employing different AI approaches, provided useful orientation for nutrient feed strategies for increased productivity. In conclusion, we believe in silico tools can perform a rapid and valid optimization of bioprocesse...

High concentrations of nitrogen compounds, such as ammonia observed in the petrochemical industry, are the major environmental pollutants. Therefore, effective and inexpensive methods are needed for its treatment. Biological treatment of various pollutants is a low cost and biocompatible replacement for current physico-chemical systems. The use of aquatic plants is an effective way to absorb th...

In the process of milk production, the highest cost relates to animal feed. Based on reports provided by the experts, around seventy percent of dairy livestock costs included feed costs. In order to minimize the total price of livestock feed, according to the limits of feed sources in each region or season, and also the transportation and maintenance costs and ultimately milk price reduction, o...

Conventional procedures are inadequate for optimizing the concentrations ofnutrients to increase the sugar yield. In this study, an artificial neural network(ANN) was used to optimize the Ca, Mg, N, K and Na content of the storage rootto increase sugar yield (Y) by increasing both sugar content (SC) and root yield(T). Data from three field experiments were used to produce a wide range ofvariati...
