Industrial water processes can be categorized into two segments - water treatment and wastewater treatment. Water treatment refers to the processes used to make water from the ground, surface or rainwater sources clean and safe for an intended use through the reduction or removal of contaminants. Wastewater treatment is the process of treating waters that have been discharged by industrial or commercial activities before they are released back into the environment. While there is a wide range of usage for each process, every industry has standardised rules and regulations that manufacturers take note of when customizing treatment machines.
