Secondary Sedimentation Tank Sludge selec System SepTnk™

Continuously improve the treatment capacity of the biochemical system

Provide New Professional Wastewater Treatment Technologies

This process reduces the ratio of inorganic compounds and light sludge in the biochemical treatment system, while boost the overall activity and settleability of the sludge.

Product Advantages

No Additional Land Required

Taking the rectangular tank as an example, it adopts an embedded channel design and merges units with the same functions, which can be modified based on the original design.

Selective Sludge Return

By subdividing the sedimentation zone, we selectively recycle denser sludge with better settling performance and higher biological activity.

Suitable for Various Processes

Ideal for use in horizontal flow sedimentation tanks, rectangular sedimentation tanks, as well as circular sedimentation tanks with central inflow and peripheral outflow.

How It Works

Without adding new wastewater treatment structures, SepTnk™ optimizes sludge collection by dividing sedimentation zones in traditional secondary tanks, improving treatment efficiency.

Influent

Sludge with a higher inorganic substance has a greater density and is more likely to settle near the influent.

Middle

The sludge flocs are denser, with a higher content of aerobic granular sludge and good biological activity.

Effluent

The sludge at the far end contains a higher proportion of aged sludge and filamentous bacteria, with lower density and poorer settling performance.
