PENURUNAN KEKERUHAN DAN TSS PADA UNIT SEDIMENTASI DENGAN APLIKASI GRANITE PLATESETLLER DAN TANPA SETTLER INSTALASI PENGOLAHAN AIR BERSIH
Abstract
Pengolahan air sederhana, sebenarnya sudah cukup lama pernah disosialisasikan. Namun, sampai saat ini akses air minum (bersih) di Indonesia masih saja rendah.Unit pengolahan air yang sangat penting adalah bak sedimentasi, karena unit ini berpengaruh besar terhadap unit proses sebelum dan setelahnya. Pengolahan air di perdesaaan, biasanya hanya menggunakan unit filtrasi sederhana berupa pasir dan ijuk. Jika kekeruhan air baku tinggi, penggunaan media pasir dan ijuk tidak efisien digunakan karena membutuhkan waktu lebih untuk pencucian ulang atau backwash media filternya.Penelitianinibertujuanmendesain model unit sedimentasi menggunakan settler modifikasi granite tile dan untuk mengetahui pegaruh “granite tile settler” dalam menurunkan total suspended solid dan kekeruhan pada unit sedimentasi pengolahan air bersih.HasilpenelitianmenunjukkanbahwaModel unit sedimentasi menggunakan settler modifikasi granite tiledapat dibangun dengan murah dan mudah diaplikasikan.Penambahan granite tile sebagai settler memberikan pengaruh terhadap penurunan kekeruhan dan TSS masing-masing dengan efisiensi 54,62% dan 61,82% sedangkan tanpa settler memberikan penurunan masing-masing dengan efisiensi 43,61% dan 43,83%.
