Settling and Separation Tank for Storm Water
Storm water treatment system
Size of particles to control: from very fine sand to very coarse sand (100 microns and over). It helps to effectively eliminate Total Suspended Solids (TSS).
Operation:
- Step 1: when it rains, surface runoff carries suspended sediments, oils and floating debris. Collection systems direct water to a storm water sewer which channels it to a settling tank.
- Step 2: when water carrying suspended pollutants enters the tank, its velocity is reduced to begin the settling process.
- Step 3: suspended solids are deposited through settling upstream from the first vertical plate.
- Step 4: Oils and floating debris are retained by the second plate.
