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.

More Information

Inspection and maintenance: inspection and maintenance are performed from the surface, using two chimneys that provide access to the sediments deposited upstream from the first plate and the oils and floating debris retained in the second compartment. Work in confined spaces is not required.

Pipe connections: Soleno offers dependable connections, compatible with all materials usually used for construction of storm water sewers (HDPE, PVC, concrete and CSP).

Separation by settling: gravity is used to separate suspended solids and oils.

Treatment capacity: Soleno’s settling tank treats up to 550l/s (145 gallons/sec) and helps eliminate sediments and suspended solids greater than 100 microns.

Installation: quick and easy, providing significant savings in project costs. Withstands CL-625, H-25 and HS-25 loads. Its size reduces excavation costs. Lightweight and durable construction.
