Peat Water Treatment Models to Produce Clean Water by Electrocoagulation Method: A Promising Solution for Raw Water

Introduction

Peat water, abundant in most of Kalimantan and Sumatra, has great potential as a source of raw water. However, the high organic content and heavy metals make peat water not suitable for consumption without processing in advance. The electrocoagulation method, which has been proven effective in treatment of wastewater and river water, offers a promising solution to produce clean water from peat water. This study aims to develop a peat water treatment model on a pilot scale using the electrocoagulation method.

Background

Peat water is a type of water that is rich in organic matter and has a high pH level. It is often used as a source of raw water for various purposes, including drinking water, irrigation, and industrial processes. However, the high organic content and heavy metals in peat water make it not suitable for consumption without processing in advance. The electrocoagulation method, which uses electrical energy to remove impurities from water, has been proven effective in treating wastewater and river water. This method is considered environmentally friendly and has low operational costs.

Methodology

This study was conducted in two stages. The first stage was carried out in the laboratory using a glass beaker to identify optimal parameters such as sample volume, aluminum sulfate concentration, and electrocoagulation time. The result of this first stage became a reference to determine the number of additional alum solutions in the electrocoagulation process. The second stage designed the peat water treatment model on a pilot scale using several tanks. This model consisted of tub 1 (sample), tub 2 (electrocoagulation process), tub 3 (filtration), tub 4 (control), and tub 5 (clean water), with a flow speed of 1 liter/minute.

Optimization of Electrocoagulation Parameters

The optimization of electrocoagulation parameters was carried out in the laboratory using a glass beaker. The parameters that were optimized included sample volume, aluminum sulfate concentration, and electrocoagulation time. The result of this optimization showed that the optimal parameters for electrocoagulation were a sample volume of 100 ml, an aluminum sulfate concentration of 10 ml/liter, and an electrocoagulation time of 10 minutes.

Pilot-Scale Peat Water Treatment Model

The pilot-scale peat water treatment model was designed using several tanks. This model consisted of tub 1 (sample), tub 2 (electrocoagulation process), tub 3 (filtration), tub 4 (control), and tub 5 (clean water), with a flow speed of 1 liter/minute. As an electrode, an aluminum plate was used with a total of 4 pieces (2 cathodes and 2 anodes) at a distance of 6 cm. To speed up the coagulation and flocculation process, aluminum sulfate solution (17% alum) was added to a sample at a dose of 10 ml/liter of sample, equivalent to 1000 ppm of alum.

Results and Discussion

The model trial results showed an increase in pH close to neutral and a significant decrease in color, turbidity, COD, BOD, total organic, and metal content of Al, Fe, Mn, Zn, Cd, and Cu. This indicates that this electrocoagulation model is capable of producing clean water that is suitable for consumption from peat water. The results of this study show that the electrocoagulation method is effective in removing impurities from peat water and producing clean water.
