Penggumpalan adalah teknik fizikal-kimia dalam olahan larut lesapan kambus tanah yang lama dan stabil. Beberapa pilihan bahan penggumpal konvesional telah digunakan. Dalam kajian ini, keupayaan Titanium tetraklorida (TiCl4) dalam olahan larut lesapan di kambus tanah Pulau Burung, Pulau Pinang, Malaysia telah dikaji. Ia dimulai dengan pencirian larut lesapan. Larut lesapan yang diuji mengandungi kepekatan yang tinggi, iaitu warna 4253 PtCo., pepejal terampai 330 mg/L, ammonia 4.4 mg/L dan UV254 0.017 cm-1. Ujian balang asas dijalankan untuk menentukan tahap optimum dan dos penggumpal. Pada pH optimum 6, dos optimumnya ialah 600 mg/L bersamaan 81.4%, 86.7%, 58.4% dan 76.5% penyingkiran untuk warna, pepejal terampai, ammonia dan UV254. Kesimpulan daripada kajian ini menunjukkan Titanium tetraklorida adalah berpotensi untuk menjadi sebagai bahan penggumpal dalam olahan larut lesapan kambus tanah semi aerobik.

Coagulation is a relatively simple physical–chemical technique in the treatment of an old and stabilized landfill leachate. A variety of conventional coagulants has been widely used. In this research, the capability of Titanium tetrachloride (TiCl4) in the treatment of stabilized leachate from Pulau Burung Landfill Site (PBLS), Penang, Malaysia was studied. The leachate was first characterized. The leachate was high in colour 4253 PtCo., suspended solids 330 mg/L, ammonia 4.4 mg/L and UV254 0.017 cm-1. Standard jar test was conducted to determine the optimum pH and coagulant dosage. At the optimum pH 6, the optimum dosage was 600 mg/L which corresponds to 81.4%, 86.7% , 58.4% and 76.5% removals for colour, suspended solid, ammonia and UV254 respectively. It can be concluded from the study that TiCl4 is potential to be used as coagulant in semi aerobic landfill leachate treatment.
