The Trans-Flo® Secondary Clarifier - Three Proven

Technologies in One

The Trans-Flo® Secondary Clarifier has combined three proven technologies - The Rim-Flo® Peripheral Feed and Takeoff Clarifier, the Tow-Bro® Hydraulic Sludge Remover and the Chain & Scraper Sludge Collection System to assure a fresher, more concentrated sludge, reduced aeration requirements and lower effluent solids.

Despite the technologies it contains, the Trans-Flo® performs in a smaller space and at lower construction and equipment costs than the average clarifier. As a new installation it requires less equipment and has lower construction costs than circular basins.

As a retrofit for existing tanks it is cost-effective because of its common wall construction, an option for large multiple tank applications or sites where space is limited. It is also well suited for replacing traveling bridges, track vacs or sludge suckers. It can be designed with greater mass loading and flow capacities in much longer and wider basins.

How It Works

The basic process is as follows:

1. Influent is introduced through a tank-length channel.
2. The downward circular flow uses the full tank volume and eliminates short circuiting while solids drop uniformly out of suspension.
3. Solids dropped to the floor are moved by the chain and flight mechanism to the sludge removal headers, which are spaced uniformly across the tank.
4. The treated water is circulated upwards and out the effluent channel.
