BIOLOGICAL TREATABILITY OF PULPING EFFLUENTS BY USING A PENICILLIUM SPECIES

Pulp and paper plants are among the most polluter industries. Their ef fluents are normally treated biologically for standard parameters such as BOD and GOD; but biological treatment is usually not complete. Unc onventional parameters unique to these wastes, such as color and organ ic halides(AOX), are virtually persistent throughout the treatment cyc le. A fungus, which is able to affect over 50% AOX and color removal f rom soft wood pulping bleachery effluents in less than two days of con tact, have been isolated and tentatively identified as Penicillum sp.
