Multilayer architectures in water purification membranes enable increased water throughput, high filter efficiency, and high molecular loading capacity. However, the preparation of membranes with well-organized multilayer structures, starting from the nanoscale to maximize filtration efficiency, remains a challenge. We report a complete strategy to fully realize a novel biomaterial-based multil...

As the natural purification of the traditional artificial floating island is very slow, the purpose of this research is to explore the efficiency of the green energy artificial floating island (GAFI) to improve water quality. We constructed experimental models near the bank of Lize Lake at MingDao University in Taiwan, where the surrounding waters and wastewater from the dormitories served as t...

Wet washing is a widely used method for biodiesel purification. However, this technique generates large amount of wastewater that needs to be treated afterward, which costly and time-consuming. Thus, solvent-aided crystallization (SAC) with ultrasonic irradiation as solution movement assistance was introduced. This based on the addition 1-butanol enhance purification via crystallization. During...

We report on the mechanisms and application of dextran-graft-polyacrylamide star-like polymers as efficient flocculation aids. Demonstrated in this paper is that these form complexes with three common radionuclide contaminants: uranium, strontium, cesium. Application flocculant aids together inexpensive kaolinite-like materials allows fast purification water. The methods presented here can be e...

This article presents the results of a study on oestrogenicity and androgenicity urban wastewater in Lodz, possibility their removal by Group Wastewater Treatment Plant (GWWTP). samples were taken at five points sewer system city inlet outlet GWWTP. The was conducted using Yeast Oestrogen Screen (YES)/Yeast Androgen (YAS) tests, which allow general assessment content compounds with (anti-)oestr...
