Formation of biofilms on the membrane surfaces and in the pores of membranes which are caused by extracellular polymeric substances and soluble microbial products has been identified as the main source of biofouling in membrane operation. The secretion of total polysaccharides and proteins by microorganisms can be lowered when they are exposed to the bismuth-BAL chelate (BisBAL) at near minimum inhibition concentration. Our study aimed at controlling the population and co-products of microorganisms that cause biofouling. After successful studies with the inhibition of Escherichia coli and Streptococcus pyogenes in activated sludge, BisBAL-containing membranes were fabricated. The effect of BisBAL on membrane performance was also observed. FTIR, SEM, contact angle, and surface roughness analyses were performed for the characterization of the membranes. Originality of this study comes from the usage of BisBAL for the first time for membrane synthesis.

Mn(NO3)2.4H2O, and Fe(NO3)3.9H2O was used as an oxidizer, while C2H5NO2, C6H8O7, and CH4N2O were used as fuel. According to XRD results, manganese ferrite was obtained as a major phase when glycine was used as a fuel, including a small amount of iron manganese oxide as a secondary phase. One of the crucial advantage of solution combustion synthesis method was to obtain high surface area, and porous powders due to large amount of gases released during synthesis method. SEM analysis confirmed that it was achieved to synthesize high surface area porous powder.
