As our group grew, we realized the need for retail and makers spaces. After grueling work getting the building ready for business, we opened officially in …
In this study, basalt fiber (BF) was modified by grafting an organic/inorganic composite, attached to which rich microorganisms were supposed to form biofilm for wastewater treatment. The modified BF (MBF) used as biofilm carriers were investigated in terms of hydrophilicity and surface roughness, which determined their bioaffinity.
Basalt ist ein basisches (SiO 2-armes) Ergussgestein.Es besteht vor allem aus einer Mischung von Calcium-Eisen-Magnesium-Silikaten und calcium- und natriumreichem Feldspat sowie meist auch Olivin.Basalt ist das vulkanische Äquivalent zum Gabbro (), der die gleiche chemische Zusammensetzung hat.. Die um 1800 geführte Auseinandersetzung über die Herkunft der Basalte, …
Feb 22, 2018· The results show that the surface-modified basalt fiber (MBF) can be successfully prepared by physical coating method. The surface roughness of MBF is 209.04nm, and the contact angle of MBF is 66.62°. Moreover, the biomass attached on MBF surface is significantly increased and the biofilm is relatively dense and homogeneous.
Jul 10, 2019· The modified basalt fiber (MBF) showed a more hydrophilic and positively charged surface. The bio-affinity of BF and MBF bio-carriers were evaluated in Bacillus subtilis adhesion and activated sludge immobilization tests. The influence of CTAC coating on the initial adhesion of bacteria and subsequent biomass immobilization was investigated.
