Wastewater treatment facilities clean and reclaim water from community sewage systems through physical, chemical and biological processes. The treated, purified water is discharged into waterways and the solids that remain undergo further treatment to eliminate pathogens, and/or disease-causing organisms.
This also reduces odor and helps to avoid attracting animals and insects that can carry disease. These solids are treated using a variety or combination of processes, including heat systems, digestion, lime stabilization, composting or hydrolysis to prepare the material for safe, beneficial use.
