This study presents the results of using viable algae to remove cadmium from a synthetic wastewater. In batch and semi-batch tests, a local strain of Cladophora algae removed 80-94% of the cadmium introduced. The flow experiments that followed were conducted using non-local Cladophora parriaudii. Results showed that the alga removed only 12.7(+/-6.4)% of the cadmium introduced into the reactor. Limited removal was the result of insufficient algal quantities and poor contact between the algae and cadmium solution.

Article Synopsis
  • Understanding microgel morphology is key for enhancing their functions in various applications, but traditional methods are often limited and low in efficiency.
  • A new bottom-up approach is introduced for creating unique non-spherical microgels from N-vinylcaprolactam using a specific liquid crystalline comonomer, allowing for more diverse shapes like multilobe, dumbbell, and raspberry forms.
  • By manipulating factors like LCM addition time, temperature, and solvent ratios, researchers can fine-tune microgel shapes, which are characterized using microscopy and light scattering techniques, and they show potential in solubilizing hydrophobic compounds like Nile Red.

Article Synopsis
  • - Vertical flow-constructed wetlands (VFCWs) can effectively treat highly polluted textile wastewater, with a focus on using biochar from the plant Phragmites karka to improve their performance and sustainability.
  • - The study compared three types of VFCWs: one without plants, one with P. karka, and one with P. karka and biochar, finding that the system with biochar (VFCW-BP) achieved the highest pollutant removal rates, including significant reductions in COD and color.
  • - Results showed that biochar not only boosted pollutant removal efficiency within 72 hours but also improved plant growth conditions, indicating VFCWs with biochar could be a cost-effective solution for textile

This study explores a novel enzymatic pretreatment approach in anaerobic reactors for dairy wastewater, using lipase AY Amano to enhance methane production and modify microbial and archaeal community composition. Batch and semi-batch reactors with a total volume of 2000 mL were used to treat dairy wastewater with initial COD of 2000 and 15,000 mg L, respectively. In a new novel approach, the semi-batch reactors underwent a three-phase operation: 30 days of acclimation, 30 days of rest, and 30 days of active operation.
