The effect of on-site use of dissolved air flotati

Product details

Total Suspended Solids (TSS) will naturally settle over time due to gravity, but this process can be sped up and improved by having an Inclined Plate. Water flows up the plate at a 60° angle. Gravity will force the solids to settle onto the plate. The particles collect on the plates will become heavier and slide back down the plate to the clarifier cone. This process creates a counter flowing pattern, where the solids are separated from the liquid into two lanes of traffic. The water flows in the upward bound lane, and the sludge flows in the downward lane. This method reduces drag and friction creating a faster settling process than if the solids were to settle naturally.

Flocculants and Coagulants are added to improve the settling time. Coagulants neutralize the negative charge particles allowing them to sink faster. Flocculants allow for the small particles to collect and accumulate. This will make the solids heavier and easier to settle.

Projected Settling Area

Inclined Plates allow for a compact design, therefore reducing the need for valuable floor space. The plates are angled at 60° allowing for an efficient projected surface area. Larger angles cast a smaller projected surface area, and shallower angles disrupt sludge flow and potentially could clog the plates. In the diagram, the Total Projected Surface Area graphically compares the equivalent floor space needed. One Standard Met-Chem Plate Pack is equivalent to a 15-foot diameter holding tank or a circular thickener.

Retention Time

Met-Chem’s design allows for a 50-60 minute retention time. This is a much better retention time than a traditional Parkson Style Clarifier which has nearly half the retention time. By having a greater retention time, this allows for more settling time, which improves the counter flowing pattern as described above. Moreover, a larger retention time Reduces the Risk to Overrun the Clarifier.
