Abstract

The aim of this study to revamp the existing laboratory scale electrolysing unit in order to increase chlorine generation and current flow as well as produce and evaluate the characteristics of electrolyzed water at optimal condition as cleaning medium in food industry. The purpose of this study is also to compare the effectiveness of revamp in chlorine generation and current flow form previous work (Sulaiman, 2018). Over the last few decades, electrolyzed water has achieved immense popularity as a novel broad-spectrum sanitizer. The simplicity of production and application is the main reason for its popularity. A sustainable and green concept of electrolyzed water has several advantages over the traditional method as it can minimize the cleaning cost, on –the-spot production ad safe for humans as well as the environment. The results shown that after revamp of electrolyzing unit, the chlorine generation and current flow increase significantly from previous work (Sulaiman, 2018). Acidic electrolyzed water (AcEW) act as sanitizer and it has the potential of eliminating foodborne pathogens for tis high bactericidal effect. While alkaline electrolyzed water (AIEW) acts as a degreaser and can replace the use of alkaline wash. Effect of electrolyzing parameters (electrode types, NaCI concentrations, Electric voltage and electrolysis time) on the chemical and physical properties (pH, oxidation-reduction potential (ORP) and free chlorine) of electrolyzed water (alkaline and acidic electrolyzed water) were optimized by using Response Surface Methodology (RSM). From the RSM and Box Behnken Design (BBD), an optimal condition for AcEW is obtained at 0.92wt% NaCI concentration, electrolysis time of 7.79min and voltage of 15.00V to produce 2.77 pH, 1035.99 mV, 11.22mg/1 free chlorine. AIEW is obtained at 0.25wt% NaCI concentration, electrolysis time of 10.00 min and voltage of 13.46V to produce 11.27pH, - 424.80mV, 0.01mg/1 free chlorine.
