Tank storage systems are designed to accommodate the specific requirements of wastewater treatment systems. Needs are suitable for every stage of wastewater treatment including flocculation tanks, mixing tanks and sedimentation tanks. The goal of wastewater storage is to clean and protect water. It means that water must be clean enough so that people can use it for drinking and washing, and by the industry for commercial purposes. It also must be clean enough to release into oceans, lakes, and rivers after it has been used.
