Analyzing the Chemical Parameters of an Studied Wooden Industry Wastewater Treatment with Advanced Ozonated System

This research reports a study in which measured values before and after ozone addition for wastewaters collected from a wooden industry treatment process. It was found that ozone reduction of particle stability (i.e., increased alpha) depended on both the ozone dose and the water hardness, which is expressed in terms of the raw-water hardness to total organic carbon (TOC) ratio. Specifically, it found increases in alpha for ozone doses of 0.4 to 0.8 mg O3 /mg TOC and hardness-to-TOC ratios of at least 25 mg CaCO3 /mg TOC. In summary, the results showed the effect of ozone on alpha depends on ozone dose, calcium and hardness and algae type. With the advances in the technology used to generate ozone, ozone is becoming more affordable to install and cheap to operate. Typically an Ozone installation will pay for itself over 12 months in chlorine savings.
