Jan 04, 2021 · Guo et al. dissolved FeSO 4 ·7H 2 O in water, stirred it vigorously at room temperature, and added Na 2 S 2 O 3 and then NaOH drop by drop. Finally, the solution was heated for 12 h at 413 K. The size of MFNs was within the range of 80–120 nm, and the magnetization saturation value was 57.59 emu/g. Solvothermal method

Cationic polyacrylamide (CPAM) has been widely used for sludge conditioning because it can neutralize the surface charge of solid and bridge particles through its …

Regarding the influence of the flocculant in the AD, it is known the negative impact of cationic polyacrylamide accumulation in the WAS after flocculation, affecting the sludge disintegration, as ...

Sludge (50.0 g) was added to a 100 mL glass reactor equipped with a temperature controller and a mechanical stirrer, and pH of sludge was adjusted by adding HCl (1.0 mol L −1 ) …

The enzyme was purified to homogeneity by salt precipitation, ionic exchange, and size exclusion chromatography with a final specific activity of 22.214 U mg⁻¹, yielding a purification fold of ...

DADMAC is a high purity, aggregated, quaternary ammonium salt and high charge density cationic monomer. Its appearance is colorless and transparent liquid without irritating smell. DADMAC can be dissolved in water very easily. Its molecular formula is C8H16NC1 and its molecular weight is 161.5. There is alkenyl double bond in the molecular ...

Cationic polyacrylamide (CPAM) has been the focus of research in environmental engineering field, particularly in sludge dewatering. However, poor stability of the existing cationic polyacrylamide ...

May 12, 2021 · While cationic polyacrylamide is widely used for treating primary sludge, digested sludge, and SAS in municipal wastewater, when industrial effluents require treatment, it is standard practice to ...

Oct 31, 2017 · The sludge sample presented an initial pH of 6.00–6.23, 98.3% moisture content, 120.2 NTU of supernatant turbidity and −17.2 mV of supernatant Zeta watering tests were carried out on a program-controlled jar-test apparatus (ZR4-6, Zhongrun Water Industry Technology Development Co., China) at room temperature (25.0 ± 0.5 °C).). The dewatering …

Jun 17, 2014 · Two cationic polyacrylamides, PAA and PAD, were synthesized for sludge dewatering. The advanced instruments such as 1H NMR, FTIR, and SEM were used to characterize the two copolymers. Their hydrophobic association properties in water were investigated by viscosimetry as well as the dewatering performance studied by the sludge …

Feb 08, 2021 · Polyacrylamide is the collective name for thousands of organic polymer electrolytes with acrylamide as the main component. Cationic polyacrylamide (CPAM) is commonly used for dewatering because sludge particles are usually negatively charged. The efficiency of sludge conditioning depends on CPAM and sludge characteristics.
