Water is purified by three successive filters 2, 3, 4, and valves 101, 26 and pump 32 enable water to be delivered to common outlet 7 from the downstream side of any selected filter. Thus water suitable for drinking is filtered by all three filters, while washing water is less purified....
centrifugation and the effect of the ethanol precipitation method because the influence of Phellodendron components in chitosan flocculation sedimentation method was more balanced,smaller loss of active ingredient.Conclusion Chitosan can be used to the purification process of the water extract of ...
Four wetland plant species(Acorus calamus,Typha orientalis,Lemna minor,Ceratophyllum demersum) were grown to compare the purification efficiency of wetland plant species alone and in combination on two eutrophic water bodies,high concentration sewage(influent) and low concentration sewage(effluent) in a...

Nanoparticles (NPs) show promising applications in biomedicine, catalysis, and energy harvesting. This applicability relies on controlling the material’s features at the nanometer scale. Surfactants, a unique class of surface-active molecules, have a re
However, the use of lepidolite in hydrometallurgy is restricted by high cost of the hydrometallurgical process for lithium recovery from this mineral as it requires a high concentration of acid and complex purification processes10. Alternative technology represents utilisation of bioleaching which becomes ...
Compared with other stem cells from neonatal tissues, hESC-MSCs have the advantages of a convenient source, sufficient cell number, and easy isolation, culture, expansion, and purification, and they still possess the characteristics of stem cells after more than 30 generations. Transplantation of h...
