The current rapid development of industrial activity indirectly discharged pollutant into the local water stream. One of the harmful industrial wastes that enter public drainage is heavy metal owing to its toxic, non-biodegradable and persistent in nature. Improper treatment of domestic waste also will discharged high amount of microbial. Various types of technology were developed for removing pollutant in wastewater, but most of the technology employed to address on removing organic content in wastewater. Other pollutant namely, heavy metals and microbial indirectly treated at low concentration of pollutant loading. Among various available technologies for water treatment adsorption process is considered a promising technology as compared to other methods because of convenience, easy operational and low cost of treatment. The aim of this study is to investigate potential used of local fruit rind modified with herb as adsorbent material. The rind present strong potential due to its high content of cellulose, pectin, hemicellulose and lignin as active binding sites for metal sorption. Modified rind improves absorption by having anti microbial properties to kill pathogenic organisms. The concentration of heavy metal ions was analysed using ICP-MS. E. coli and total colifrm were plated out using chromocult agar. The results showed significant reductions of heavy metals and microbial concentration after wastewater was treated with clove modified rind.
