Dataset for laundry wastewater treatment.

No ethical clearance required for this study.<br>The purpose of this research was to investigate and evaluate the impact of ECF process variables such as mixing, electrode types; initial pH, voltage supply and volume had on TSS, turbidity, pH, Chlorides (Cl^-), and free chlorine (fCl2) and Hazen true colour removal. DoE Minitab software was used to design the order in which the experiments would were going to be run and analysed. Five factors set lower and higher values such as (i) mixing (0 to 500 r/min), (ii) Voltage (10 to 15 V), (iii) Initial pH (3.5 to 8.5), (iv) effluent volume (800 to 2000 mL) and (v) electrode types (aluminium and stainless steel) were investigated.Generally, Hazen true colour, chlorides, and free chlorine analysis require sample preparation for pH adjustment and turbidity removal. The samples were centrifuged at 4500 rpm or filtered with 0.45 µm membrane sheets to remove or lower turbidity and neutralise to pH 7.6 to avoid interferences for some analyses.<br>

本研究旨在探究并评估电化学絮凝（ECF）工艺变量——涵盖搅拌速率、电极类型、初始pH值、供电电压及处理体积——对总悬浮固体（TSS）、浊度、pH值、氯化物（Cl⁻）、游离氯（fCl₂）以及哈真真色度去除效果的影响。本研究借助实验设计（DoE）Minitab软件规划实验的执行流程与分析方案。本次研究共考察5个因素的高低水平设置：(1) 搅拌速率（0~500 r/min）；(2) 供电电压（10~15 V）；(3) 初始pH值（3.5~8.5）；(4) 处理体积（800~2000 mL）；(5) 电极类型（铝电极与不锈钢电极）。
通常情况下，哈真真色度、氯化物及游离氯的检测分析需对样品进行前处理，包括pH调节与浊度去除。
本次实验通过4500 rpm离心或使用0.45 µm微孔滤膜过滤的方式，去除或降低样品浊度，并将pH值中和至7.6，以规避部分检测分析中的干扰因素。
