Kajian ini mengkaji pengaruh parameter operasi untuk loji rawatan air sisa industri. Pengeluaran perindustrian seperti syarikat peranti perubatan mencipta kuantiti yang banyak dan jenis air sisa yang mengakibatkan pencemaran alam sekitar yang serius. Air buangan lateks adalah salah satu air sisa industri yang dihasilkan dari produk pembuatan yang berasal dari bahan pemprosesan lateks. pH air buangan lateks adalah kira-kira 3.88 dan ia berada dalam keadaan berasid. COD, BOD dan Warna air buangan lateks masing-masing adalah 1093mg/L, 48.8mg/L dan 1751PtCO. Terdapat beberapa proses rawatan untuk merawat air kumbahan industri dan secara amnya dibahagikan kepada tiga tahap rawatan iaitu rawatan fizikal, kimia dan biologi. Dalam kajian ini, lima tempat terpilih dalam loji rawatan air sisa lateks dimonitor dan kecekapan penyingkiran telah dibandingkan antara rawatan fizikal, kimia dan biologi. Rawatan fizikal, kimia dan biologi loji rawatan terpilih adalah perangkap getah, pembekuan dan pemberbukuan dan rawatan biologi menggunakan Mikroorganisma Berkesan. Kecekapan penyingkiran purata COD, BOD, Warna dan TSS untuk rawatan biologi masing-masing adalah 79%, 39%, 74% dan 78%. Kemudian, rawatan kimia menggunakan kaedah pembekuan dan pemberbukiran dan ferric chloride sebagai koagulan boleh dikeluarkan 56% COD dan 28% BOD dalam air buangan lateks. Semasa proses rawatan pembekuan dan pemberbukuan, 53% TSS dan 38% Warna telah dikeluarkan. Rawatan yang paling berkesan ialah rawatan biologi menggunakan (EM). Hasilnya juga memperlihatkan parameter kajian efluen yang dirawat berikut pelepasan standard B untuk efluen perindustrian.

The research attempts to study the influence operational parameters for industrial wastewater treatment plant. Industrial production such as medical device company create large quantities and varieties of wastewater that are causing serious environmental pollution. Latex wastewater is one of the industrial wastewater generated from manufacturing product that originated from latex processing material. The pH of latex wastewater is about 3.88 and it was in acidic condition. The COD, BOD and Color of latex wastewater were 1093mg/L, 48.8mg/L and 1751PtCO respectively. There are several treatment processes to treat industrial wastewater and it generally divided into three stages of treatment which is physical, chemical and biological treatment. In this study, five selected points in the latex wastewater treatment plant was monitored and the removal efficiencies was compared between physical, chemical and biological treatment. Physical, chemical and biological treatment of the selected treatment plant was rubber trap, coagulation and flocculation and biological treatment using Effective Microorganism. The average removal efficiency of COD, BOD, Colour and TSS for biological treatment are 79%,39%,74% and 78% respectively. Then, chemical treatment using coagulation and flocculation method and ferric chloride as coagulant able removed 56% of COD and 28% of BOD in latex wastewater. During coagulation and flocculation treatment processes, 53% of TSS and 38% of Colour have removed. The most efficient treatment is biological treatment using (EM). The result also shows the studied parameter of treated effluent follows the standard B discharge for industrial effluent.
