Influence of Critical Parameters on the Extraction of Concentrated C-PE from Thermotolerant Cyanobacteria.

This work aimed to identify the influence of pH, molarity, / fraction, extraction time, agitation, and either a sodium (NaHPO·7HO-NaHPO·HO) or potassium buffer (KHPO-KHPO) used in the extraction of C-phycoerythrin (C-PE) from a thermotolerant strain of sp. An experimental design (Minimum Run Resolution V Factorial Design) and a Central Composite Design (CCD) were used. According to the statistical results of the first design, the K-PO buffer, pH, molarity, and / fraction are vital factors that enhance the extractability of C-PE.

Bicarbonate-Hydrogen Peroxide System for Treating Dyeing Wastewater: Degradation of Organic Pollutants and Color Removal.

The textile industry is a global economic driving force; however, it is also one of the most polluting industries, with highly toxic effluents which are complex to treat due to the recalcitrant nature of some compounds present in these effluents. This research focuses on the removal of Chemical Oxygen Demand (COD), color, Total Organic Carbon (TOC), and Ammoniacal Nitrogen (N-NH) on tannery wastewater treatment through an advanced oxidation process (AOPs) using sodium bicarbonate (NaHCO), hydrogen peroxide (HO) and temperature using a central composite non-factorial design with a surface response using Statistica 7.0 software.

Advanced Oxidation Processes and Biotechnological Alternatives for the Treatment of Tannery Wastewater.

The tannery industry is one of the economic sectors that contributes to the development of different countries. Globally, Europe and Asia are the main producers of this industry, although Latin America and Africa have been growing considerably in recent years. With this growth, the negative environmental impacts towards different ecosystem resources as a result of the discharges of recalcitrated pollutants, have led to different investigations to generate alternative solutions.

Multiparameter analysis of activated sludge inhibition by nickel, cadmium, and cobalt.

Activated sludge processes are often inhibited by nickel, cadmium, and cobalt. The inhibitory effect of these heavy metals on a synthetic wastewater treatment process was tested through pulse microrespirometry; i.e.
