Abstract
The provision of clean water is an urgent need that must be realized in order to solve the problems that continue to be faced by people living on peatlands. The purpose of this research is to process peat water into clean water using nanofiltration method by ceramic membrane based on clay, activated carbon nanoparticles of Oil Palm Empty Fruits Bunch (OPEFB) as an additive and iron powder as a reinforcement. Peat water is first neutralized by addition of quicklime then processed through various microfiltration methods with sponges with pore sizes, namely 0.5 µm, 0.3 µm 0.1 µm and activated carbon and finally processed through ceramic membranes made from OPEB activated carbon nanoparticle additives. The pressure is set at 1 bar, 1.5 bar and 2 bar. The raw material for peat water from the Telang River is acidic with a pH value of 4.1 and contains TSS 147.5 mg/L, Fe 0.33 mg/L, Mn 0.56 mg/L, Zn 0.02 mg/L, NH3- N 0.58 mg/L, NO2-0.19 mg/L, PO4-3 0.264 mg/L, and BOD5 12.1 mg/L. It was found that, the greater the transmembrane pressure difference and the longer the operating time used, the better the permeate yield. The difference in pressure of 2 bar gives the best results in reducing the levels of contaminants contained in peat water with an average percent rejection reduction of TSS 91.89%, Fe 70%, Mn 93.2%, Zn 95%, NH3-N 68, 6%, NO2- 70%, PO4-3 38.14%, and BOD5 91.99%
