Abstract
Konsentrasi polutan metilen biru yang diperbolehkan berada di perairan memiliki nilai ambang batas sekitar (5-10) mg/L sedangkan limbah industri tekstil memiliki kadar sekitar (20-30) mg/L. Keberadaan metilen biru yang berlebih di dalam perairan merusak ekosistemnya. Metode fotokatalisis merupakan salah satu metode yang dapat mengurangi kadar metilen biru dalam air. Telah berhasil dilakukan peningkatan kemampuan reaktor fotokatalisis “zuiverious” untuk mendegradasi kadar metilen biru dalam air dengan penataan substrat TiO2 (sebagai fotokatalisis) dalam reservoir proses. Substrat TiO2 disusun melingkar koaksial terhadap sumber cahaya lampu UV (jenis TL) yang ditempatkan di tengah reservoir proses. Hasil penelitian menunjukkan bahwa struktur penataan substrat TiO2 yang telah dilakukan mampu mendegradasi polutan metilen biru sebesar 8,05998 ppm (dari konsentrast awal 20 ppm). Hasil lain menunjukkan bahwa laju fotodegradasi metilen biru di siang hari (pukul 10.00 hingga 16.00) lebih besar dibanding waktu yang lain.

The permissible concentration of methylene blue
pollutant in the waters has a threshold value of about (5-10) mg/L
while the textile industry waste has levels of around (20-30) mg/L.
The presence of excess methylene blue in the waters destroys the
ecosystem. Photocatalysis method is one method that can reduce
the levels of methylene blue in water. It has been successful to
improve the ability of the "zuiverious" photocatalytic reactor to
degrade the levels of methylene blue in water by structuring the
TiO2 substrate (as photocatalyst) in the process reservoir. The
TiO2 substrate was arranged in a coaxial circle with a UV lamp
light source (TL type) placed in the center of the process
reservoir. The results showed that the structure of the TiO2
substrate arrangement that had been carried out was able to
degrade methylene blue pollutants by 8.05998 ppm (from the
initial concentration of 20 ppm). Other results showed that the
photodegradation rate of methylene blue during the day (10am to
4pm) was higher than other times.
