Bioregeneration of activated carbons by bacterial degraders after adsorption of surfactants from aqueous solutions

Adsorption, desorption and bioregeneration in the treatment of 2-chlorophenol with activated carbon

“…The mechanism of bioregeneration of activated carbon includes subsequent biodegradation. The second theory mentioned in literature is about desorption of organic matter as a result of exoenzymatic reactions [4,6,7].…”

Microbial regeneration of spent activated carbon dispersed with organic contaminants: mechanism, efficiency, and kinetic models

“…(Aktas and Cecen 2007a). Besides synthetic surfactant mixture, non-iogenic surfactant, sulfonol have also been used by various workers (Klimenko et al 2004;Sirotkin et al 2001). Coelho et al (2006) demonstrated the bioregeneration of herbicide molinate loaded activated carbon using mixed microflora.…”

“…Bioregeneration of activated carbon is controlled by the reversibility of adsorption (Klimenko et al 2004). At equilibrium, adsorbable substance is distributed between the solution and the powdered activated carbon (PAC) surface.…”

“…Effective bioregeneration requires certain microbiological and physico-chemical preconditions as stated below (Klimenko et al 2004 Major target compounds for adsorption-bioregeneration are stated in the following section.…”

Utilização de carvão ativado biológico para o tratamento de água para consumo humano

“…A cinética da degradação biológica em biofilmes apresenta três aspectos relevantes (RITTMAN & HUCK, 1989 KLIMENKO et al, 2003).…”
