THIS PROJECT PRESENTS BANANA TRUNK FIBER AS THE MAIN FILTERING LAYER IN A WASTE WATER FILTER SYSTEM. THE MAIN PURPOSE OF USING BANANA TRUNK FIBER IS BECAUSE IT WAS PROVED FROM PAST RESEARCH, THAT BANANA TRUNK FIBER HAS THE CAPABILITY TO ABSORB 70% TO 80% OIL AND GREASE IN SAMPLED WASTE WATER DEPENDING ON THE NATURE OF THE PROCESSED BANANA TRUNK FIBER THAT WAS USED AS A FILTER. KITCHEN SINK WASTE WATER OFTEN CREATE PROBLEMS SUCH AS CLOGGING IN THE SEWAGE SYSTEM, WATER POLLUTION AND ALSO INCREASE THE WORKLOAD OF A SEWAGE PLANT. THIS FILTER SYSTEM IS DESIGNED TO BE APPLIED IN DOMESTIC OR RESIDENTIAL KITCHEN SINK. THE APPLICATION OF THIS FILTERING SYSTEM NOT ONLY FILTERS OUT OIL AND GREASE BUT WILL ALSO REDUCE TURBIDITY, PH AND SUSPENDED SOLIDS OF THE WASTEWATER DISCHARGED INTO THE SEWAGE SYSTEM. IN CONCLUSION, THE USAGE OF BANANA TRUNK FIBER AS A FILTER HAS A SIGNIFICANT IMPACT IN REDUCING CLOGGING AND WORKLOAD OF SEWAGE TREATMENT PLANTS DUE TO HIGHER-LOAD GREY WATER FROM KITCHEN SINK.
