Ultrafiltration Membranes for Oil Sands Wastewater

Check if the same lab product or an alternative is used in the 5 most similar protocols

The ultrafiltration membranes were made using the PES polymer with a molecular weight of 58 kDa obtained from BASF (Ludwigshafen, Germany). PVP (molecular weight, MW: 360 kDa) was procured from Sigma Aldrich (St. Louis, MO, USA) and used as an additive. Potassium chloride (KCl) and N,N-dimethylacetamide (DMA) were purchased from Fisher Scientific (Waltham, MA, USA). The discrete TiO₂ NTs were synthesized using an electrochemical anodization process followed by sonication for discretization. Diethylene glycol (DEG) and ammonium fluoride (NH₄F) were purchased from Sigma Aldrich to be used as an electrolyte in electrochemical anodization. Octadecylphosphonic acid (ODPA) to functionalize discrete nanotubes was also indented from Sigma Aldrich. An industrial wastewater, produced from steam-assisted gravity drainage (SAGD) in the Athabasca oil sands industry (AB, Canada) was used for the membrane permeation and fouling characteristics tests. The produced water is the feed water to the warm lime softener (WLS) of current SAGD water treatment facilities.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
