the effect of salinity on organic removal and ammonium oxidation in a down-flow hanging sponge reactor was investigated by conducting a long-term continuous experiment over a period of 800 days. the dhs reactor, constructed by connecting three identical units, was fed with artificial wastewater containing 500 mg-n/l of ammonium nitrogen and 1400 mg- cod/l of phenol. salinity of the influent wa...
Sponges are suspension feeders that use flagellated collar-cells (choanocytes) to actively filter a volume of water equivalent to many times their body volume each hour. Flow through sponges is thought to be enhanced by ambient current, which induces a pressure gradient across the sponge wall, but the underlying mechanism is still unknown. Studies of sponge filtration have estimated the energet...
Objective: The aim of this study was to explore the effect of endothelial progenitor cells (EPCs)-collagen sponge complex on the neovascularization of chronic cerebral ischemia following multiple burr hole (MBH) surgery. Methods: Bone marrow-derived EPCs from 5 Fisher 344 (F344) inbred rats were cultured and amplified in vitro, then co-cultured to become the EPCs-collagen sponge complex. Chroni...
This study was carried out to assess the efficiency of a combined system consisting of up-flow anaerobic sludge blanket (UASB) reactor and down-flow hanging sponge (DHS) system for color removal from reactive dyes wastewater. The UASB reactor and DHS system were operated at HRT of 6 and 2.0 h., respectively. The results obtained indicated that, the combined system was quite effective for remova...
Anaerobic oxidation of methane (AOM) in marine sediments is an important global methane sink, but the physiological characteristics of AOM-associated microorganisms remain poorly understood. Here we report the cultivation of an AOM microbial community from deep-sea methane-seep sediment using a continuous-flow bioreactor with polyurethane sponges, called the down-flow hanging sponge (DHS) biore...
