Industri tekstil adalah salah satu industri utama di dunia yang menggunakan kuantiti air yang banyak dan mengeluarkan jumlah yang besar air sisa. Olahan adalah penting sebelum air sisa ini dapat sebebaskan ke alam sekitar bagi melindunginya. Koagulasi dan Flokulus adalah proses yang agak mudah yang biasa digunakan untuk merawat air sisa tekstil. koagulan akan bertindak sebagai ejen bagi caj-caj elektrik daripada zarah dalam air sisa tekstil dineutralkan. Pelbagai koagulan konvensional seperti aluminium sulfat, ferik sulfat dan ferik klorida telah digunakan secara meluas. Titanium (IV) tetraklorida (TiCl) telah diuji dalam kajian ini dan ia tidak pernah digunakan bagi koagulan dalam olahan air sisa tekstil sebelum ini. Dalam kajian ini, keupayaan Titanium (IV) tetraklorida (TiCl) telah dikaji untuk merawat air sisa kumbahan tekstil dari kilang pembuatan tekstil yang terletak di Kawasan Perindutrian Perai, Pulau Pinang. Air sisa tekstil yang dicirikan terlebih dahulu. Air sisa tekstil mempunyai warna, pepejal terampai, Permintaan Oksigen Kimia ( COD), Ammonia dan kekeruhan yang tinggi. Ujian balang telah dijalankan untuk menentukan pH optima dan dos optima dalam menghapuskan warna, pepejal terampai, ammonia, Permintaan Oksigen Kimia, dan kekeruhan. Pada dos optimum 300mg/L dan pH 6, peratus penyingkiran masing-masing adalah 98.8%, 22,14%, 99,64%, 82,04% dan 56,16% untuk kekeruhan, warna, pepejal terampai, ammonia dan COD. Titanium tetraklorida adalah koagulan baik dalam menghilangkan kekeruhan , pepejal terampai dan ammonia tetapi tidak berkesan dalam menghilangkan warna dan COD.

Textile industry is one of the major industries in the world and consumes a lot of water and produce large amount of wastewater. The treatment is important before this wastewater is release to environment in order to protect it. Coagulation and flocculation is relatively simple physical chemical technique that commonly been used to treat textile wastewater. Coagulation acts as neutralizing agents for electrical charges of particle in textile wastewater. A variety of conventional coagulants such as aluminium sulphate, ferric sulphate and ferric chloride has been widely used. Titanium (IV) Chloride (TiCl4) was tested in this research and it has never been applied for textile wastewater treatment before. In this research, the capability of Titanium (IV) Chloride (TiCl4) has been studied to treat textile wastewater from textile factory, that is located at Perai Industrial Estate, Penang. The textile wastewater was first characterized. The textile wastewater has high value of colour, suspended solids, Chemical Oxygen Demand (COD), Ammonia and Turbidity. Standard jar test was conducted to determine the optimum pH and dosage in removing colour, suspended solids, ammonia, Chemical Oxygen Demand, and Turbidity. Standard jar test was conducted to determine the optimum pH and coagulant dosage. At optimum dosage 300mg/L and pH 6, the percentage of removal are 98.8%, 22.14%, 99.64%, 82.04% and 56.16% for turbidity, colour, suspended solid, ammonia and COD respectively. Titanium tetrachloride is good coagulant in removing Turbidity, suspended solid and ammonia but not efficient in removing colour and COD.
