Summary: Compost from pine bark has shown effective adsorption for different classes of textile dyes. The adsorption capacity was higher for Basic Violet 10 (BV10) than for Direct Blue 151 (DB151) in batch conditions, and competition reduced the uptake of both dyes. Furthermore, the presence of both dyes in solution decreased their affinities in column tests. The column biosorbent could be effectively regenerated using ethanol.

Summary: This study investigates the adsorption of substances contributing to COD in secondary treated effluents of pulp and paper mills using CoFe2O4 and quartz sand-coated CoFe2O4. The experiments demonstrate that CoFe2O4-coated sand has good adsorption performance and stability. Results show that an increase in feed flow rate and initial pH can decrease breakthrough time, while an increase in bed depth can increase breakthrough time.

Summary: The study found that Spirulina has higher removal capacity at pH 5.2 and lower adsorption capacity at higher ionic strength, suggesting ion exchange as a relevant mechanism. Immobilizing Spirulina on alginate beads not only increases adsorption capacity but also overcomes limitations in column systems. Dose-response model was the most appropriate to describe the biosorption process.

Summary: The study investigated the adsorption of phosphorus in low-concentration phosphorus wastewater using a modified calcium-modified attapulgite (Ca-GAT). The study explored the effects of various parameters on dynamic phosphorus adsorption and found that the adsorption ability improved with increased bed height and flow rate, and decreased initial phosphorus concentration. Breakthrough curves were fitted using four models, with the Thomas model determining a maximum adsorption amount of 13.477 mg/g. The study also found that NaOH regeneration had the best effect, and the breakthrough point was achieved after 177 hours in treating actual MBR effluent. These findings suggest that Ca-GAT has potential for the treatment of low-concentration phosphorus wastewater.
