Photocatalytic degradation of palm oil mill secondary effluent (POMSE) using zinc oxide nanoparticles

Palm oil mill secondary effluent (POMSE) properties still does not achieve the discharged requirement by the department of environment (DOE). Hence, it would be a solution to the POMSE treatment to recover and reuse the photocatalyst as to meet the development of greener and advanced technolog...
