Treatment of toilet odor using horizontally placed odor removal membrane

Treatment of toilet odor using horizontally placed odor removal membrane / Nuramalina Md.Nor
Kekerapan tandas digunakan dan aktiviti yang dijalankan di dalamnya membawa kepada keadaan yang buruk di mana terdapat bau yang tidak menyenangkan dan keadaan ini sering menjadi kebimbangan terhadap penggunanya. Terdapat beberapa kaedah yang digunakan dalam menangani isu bau di dalam tandas seperti meningkatkan kekerapan tandas itu dibasuh, penggunaan pewangi tandas dan juga reka bentuk pengudaraan tandas yang baik. Kajian ini bertempat di tandas asrama perempuan di Desasiswa Lembaran, dijalankan untuk memberi tumpuan kepada rawatan bau tandas menggunakan membran penyingkiran bau, iaitu Deodoratex. Kecekapan pengendalian bau kedua-dua jenis kain ini iaitu Deodoratex, Jenis 03 dan Jenis 32 yang digunakan dalam kajian ini dinilai dengan mengukur kepekatan unit bau (OU / m³) dan intensiti bau di dalam tandas sebelum dan selepas pemasangan kain . Penyingkiran ammonia dan hidrogen sulfida yang tidak menentu juga diukur dan dibandingkan dengan kedua-dua fabrik dalam kedua-dua keadaan (sebelum dan selepas pemasangan). Ujian penyerapan ammonia juga dilakukan pada fabrik untuk menentukan keupayaan kain untuk benar-benar menyerap kepekatan ammonia. Kedua-dua jenis kain ini menunjukkan kecekapan kawalan bau yang bagus di dalam tandas walaupun bau bervariasi dan bau intensiti dari semasa ke semasa. Fabrik ini juga memberikan keputusan yang positif dalam ujian kecekapan penyingkiran bau di mana Jenis 32 menunjukkan peratusan yang lebih besar dalam penghapusan ammonia dan hidrogen sulfida. Dalam ujian penyerapan ammonia, fabrik menunjukkan kesan yang ketara ke atas ammonia kerana jumlah ammonia selepas ujian lebih rendah jika dibandingkan dengan jumlah ammonia yang tidak dirawat. Fabrik Jenis 32 mempunyai jumlah ammonia-nitrogen yang lebih tinggi apabila air basuhannya diuji menggunakan Hach Spectrophotometer. _______________________________________________________________________________________________________ Toilet is considered the most visited place in a home or in public. The frequency of the toilet being used and the activity conducted in it led to a bad condition where it can have offensive smell and the odorous condition of the toilet often be a concern towards its users. There are several methods applied in dealing with odor in the toilet such increasing the frequency of the toilet being washed, the application of fragrance and also a wise toilet’s ventilation design. This study that took place in toilet located in girl’s hostel at Desasiswa Lembaran, was conducted to focus on treatment of the toilet’s odor using odor removal membrane, which is Deodoratex. The odor control efficiency of the both type of Deodoratex fabrics, Type 03 and Type 32 that are used in this study are evaluated by measuring the odor unit concentration (OU/m³) and odor intensity in the toilet before and after the installation of the fabrics. The removal of ammonia and hydrogen sulfide also being measured and compared for both fabrics in both situation (before and after installation). Ammonia adsorption test also conducted on the fabrics to determine the capability of the fabrics to really adsorb ammonia concentration. Both fabrics shows a great odor control efficiency in the toilet even the odor intensity and odor character varies from time to time. These fabrics also have a positive values of odour removal efficiency where fabric Type 32 shows a greater percentage in removal of ammonia and hydrogen sulfide. In the ammonia adsorption test, the fabrics showed significant effects on ammonia gas as the concentration of ammonia after the test was lower compared to the concentration of untreated ammonia. Type 32 fabrics have higher amounts of ammonia-nitrogen when the washing water is tested using the Hach Spectrophotometer.
