Abstract
Air buangan penyudah logam yang dikaji bukan sahaja mempunyai kandungan logam berat melebihi had yang ditetapkan oleh Piawai B, Akta Kualiti Alam Sekeliling 1974, Peraturan-Peraturan Kualiti Alam Sekeliling (Kumbahan
dan Efluen-Efluen Perindustrian) 1979 malah mempunyai nilai keperluan oksigen kimia (COD) sangat tinggi iaitu melebihi 10,000 mg/L.
Metal finishing wastewater used in this study contained not only heavy metals that exceed the standard limits as stipulated in the Environmental Quality Act (EQA) 1974, under Sewage and Industrial Effluent, Environmental Quality
Regulations 1979 for Standard B, but also had a very high levels of chemical oxygen demand (COD) which was more than 10,000 mg/L.
