Solids Settling tank (SST)

When washing with a Hydropad portable wash rack system where little or no solids settling is available, the SST is perfect. Why put water-settling storage in ground where you find it difficult to clean out? The SST is self-cleaning.

• Gravity flow-through design
• Flow rates of 25 and 50 GPM
• Passive/active gravity solids separation
• Self-cleaning tank makes sludge removal easy
• Overflow protection device
• Optional continuous solids removal to 5 micron nominal with a continuous media automatic filtration unit (CMAFU-2)
• Factory assembled and tested

How The SST Works

When below ground, water storage is inadequate for solids settling; above-ground solids settling becomes very useful. Water is pumped from any collection point to the SST. Wastewater is directed though a liquid quieting well tube where its velocity is slowed to as low as 3 FPM. The wastewater is forced to reverse course 180 degrees in order to exit the SST, allowing solids to settle to the bottom. Clarified wastewater is drawn through a cascade collection system and directed to the exit port. The SST flow is governed by gravity and is self-regulating. Its self-cleaning cone bottom tank can be manually or automatically purged, depending on the system configuration. The addition of the optional CMAFU-2 polishing loop continuously removes accumulated sludge from the bottom of the SST. During periods of low flow the CMAFU-2 polishing loop super-cleans the wastewater to <5 or 1 microns nominal.
