Abstract

BACKGROUND AND AIM: WATER IS ESSENTIAL FOR ALL KNOWN LIFEFORMS, STILL, WATER POLLUTION AND THE DESTRUCTION OF ECOSYSTEMS CONTINUE TO INCREASE. WATER CONTAMINATION IS NOW A MAJOR PROBLEM IN THE GLOBAL CONTEXT AS A CONSEQUENCE OF INDUSTRIALISATION, GLOBALIZATION AND POPULATION GROWTH.BIOFILMS TREATMENT SYSTEMS EMPLOY THE USE OF BACTERIA, FUNGI, ALGAE, AND PROTOZOA TO REMOVE ORGANIC AND INORGANIC MATERIALS FROM WASTEWATER THROUGH OXIDATION OF ORGANIC PARTICLES AND NITRIFICATION OF AMMONIUM. THIS STUDY FOCUSED ON THE GROWTH AND EFFECTIVENESS OF BIOFILMS IN A REACTOR OF DILUTED WASTEWATER.METHODS: DURING THIS PROJECT FOUR BIOFILMS WERE GROWN IN A REACTOR TANK, TWO WERE ON NYLON MESH FRAMES AND TWO WERE ON PLASTIC MEMBRANES, ONE AERATED AND ONE ANAEROBIC. THE REACTOR TANK CONSISTED OF 50 LITERS OF DILUTED WASTEWATER WHICH WAS CIRCULATED AND OXYGENATED TO IMITATE A RIVER. TO DETERMINE THE EFFICIENCY OF BIOFILMS IN WASTEWATER TREATMENT, DAILY SAMPLES OF THE WASTEWATER WERE TESTED USING THE TOC METHOD.RESULTS: THROUGHOUT THE EXPERIMENT, MORE BIOFILM GROWTH WAS OBSERVED ON THE NYLON MESH FRAMES THAN ON THE PLASTIC MEMBRANE FRAMES. FURTHERMORE, COLONIZATION ON THE AERATED MEMBRANE SURPASSED THAT OF THE ANAEROBIC MEMBRANE.CONCLUSION: OVERALL, FROM THIS STUDY, IT HAS BEEN CONCLUDED THAT THE APPLICATION OF BIOFILMS IS AN EFFECTIVE STEP IN THE BIOLOGICAL TREATMENT OF WASTEWATER. EVEN THOUGH THE DEVELOPMENT OF THE BIOFILM TAKES TIME, THE FILMS ARE PROFICIENT IN INCREASING WATER QUALITY BY OXIDIZING AMMONIUM AND ORGANIC COMPOUNDS IN WASTEWATER.
