The developed microbial granules containing photosynthetic pigments had successfully achieved approximately 18–21% of carbon dioxide (CO2) removal in POME for one complete SBR cycle. Also, the granules had reached CO2 removal at 15–29% within 24h and removal of 25% after 5 days. Both results were inconsistent possibly due to the slow mass transfer rate of CO2 from gas to liquid as well as the simultaneous...
Phenolic resins such as resol or novolac phenol-formaldehyde (PF) ones have been synthesized and etherified with poly(ethylene glycol) (PEG) with different molecular weights (1000, 1500, 4000). The solution behaviors in aqueous medium of the prepared resol and novolac phenol-formaldehyde ethoxylated resins, as nonionic polymeric surfactants with different hydrophilic chains lengths, have been interpreted...
