Recent studies have focused a significant amount of attention on the problem of dyes in water because of their adverse outcomes for the environment and people’s life. In the current work, the adsorption capacity of the sawdust of grapevine wood (GVW) from agricultural waste was employed as a new inexpensive, and green biosorbent via a batch adsorption process. Sulfuric acid was applied to grapevine wood to activate the sorbents for methylene blue (MB) elimination from the solution medium under varied parameters, including temperature, pH, original MB content, contact time, and adsorbent dimensions. The optimum capacity for adsorption ( q max ) of 220.51 mg·g –1 at 293 K was obtained after 180 min of solid/liquid contact with 1 g·L –1 activated grapevine wood (GVWA) sawdust. The Freundlich and pseudo-second-order systems were given the optimal isotherm and kinetic results for MB biosorption onto GVWA sawdust using linear and non-linear regression techniques. The findings for MB biosorption exhibit that non-linear regression was the best approach to choosing the optimum kinetic and isotherm models. The calculated standards for entropy change, standard enthalpy change, and standard Gibbs free energy change demonstrated that the adsorption dynamic was exothermic, spontaneous, and advantageous. Our findings suggest that sustainable and cost-effective GVWA is a suitable candidate for removing emerging contaminants like MB from contaminated waters.

Circulating cooling water consumes a large amount of water in thermal power plant, and there are some problems such as scaling and corrosion in the system. This study presents a novel circulating cooling water treatment process based on microbes. The mechanism and influencing factors of microbial treatment process of circulating cooling water is studied. Water from circulating cooling system of a 300 MW thermal power unit was used, dynamic simulation test was carried out and com- pared between the microbial treatment process and the traditional chemical treatment process. The results showed that nutrient solution dosage on calcium hardness is positive, while the interaction between nutrient solution dosage and aeration rate has negative effect. When ammonia concentration is 10–50 mg/L and aeration rate is 1–3 L, and the minimum calcium hardness is 18.3 mmol/L. Reducing the concentration of nutrient solution and increasing the aeration rate are beneficial to slow down the corrosion of carbon steel and stainless steel. When ammonia concentration is 10–50 mg/L and aeration rate is 1–3 L, the minimum corrosion rates are 0.01552 and 0.00110 mm/a, respectively. Compared with traditional chemical treatment process, the microbial treatment process can achieve the scale inhibition and corrosion inhibition target at high concentration ratio, the highest concentration ratio can reach 5.4, and the corrosion rate of carbon steel and stainless steel is low. The green, efficient and environment-friendly microbial treatment process provides a new method for circulating cooling water treatment, which can obtain stable and economical operation of circulating cooling water system under high concentration ratio.
