in porous media under ,dynamic, conditions is still a crucial issue. In this research, synthesised silica nanoparticles modified with ,acid, treatment (Si11A) evaluated in previous results in the bentonite-free water-based drilling fluid (BFWBM) in static tests were analysed in the coreflooding test under ,dynamic, and reservoir conditions.

Nitrogen removal from salt-bearing aquaculture ,wastewater, was investigated at different chloride concentration using ,dynamic, membrane bioreactor. Using the activated sludge model No.1 (ASMl) to simulate the DMBR by Biowin, the results showed that changing the values of KO,H, KNO and bH, the model values of NO3--N and TN was almost same to the experiment values, the deviation were about …

26/2/2020, · In the ,dynamic, tests under reservoir conditions, it was observed that nanoparticles with acidic treatment added to the drilling fluid reduce the ,filtration, volume by 77% and inhibit the reduction of the oil effective permeability by 76% regarding the drilling fluid in the absence of the nanomaterial.

In DMBR, the dynamic membrane (DM) layer acts as the main source of filtration resistance after its formation . Since the DM layer is a kind of surface sludge layer that can release smaller particles, the deposited organic material when gets more than the filtration capacity will block the membrane pores and cause membrane fouling issues in DMBR.
