Optimizing wastewater plants with innovative technology

A systemic approach to wastewater treatment plants

Our strategy at Densiline South America (DSA) revolves around optimizing wastewater treatment plants using our patented hydraulic booster, Speed-o-Clar®, designed specifically for secondary clarifiers of activated sludge wastewater treatment plants. We focus on improving hydraulics to enhance overall plant efficiency.

As activated sludge wastewater plants are a complete and complex body, their heart is the clarifier and the efficiency of its hydraulics. This is where Speed-o-Clar® comes into action first.

Its design and action allow the lamination of turbulent flows, improving sedimentation, allowing an increased flow to be treated, and possibly a higher concentration of the sludge (RAS-WAS).

The results we obtain on hydraulics improvement allow us to get in-depth with a systemic approach to wastewater treatment plants. We conduct analysis and propose additional innovative solutions to be applied throughout the different processes of the treatment plants.

Transforming hidraulics into a secondary clarifier

Speed-o-Clar® technology is customized for each clarifier based on operational, design, and construction parameters. It features an activating chamber and a combination of deflectors and diffusers to create laminar flows, depressions, and counter-currents. This enhances floc agglutination and accelerates sedimentation towards the RAS/WAS.

Our Company

DSA originated in Chile in 2022, following the success of Densiline France, which started in 2001. Densiline France focused on understanding fluid characteristics, developing innovative products. The current improved concept of Speed-O-Clar® was launched in early 2022, and over 50 wastewater plants in France and Chile are equipped with it.

Speed-O-Clar® has received the SOLAR-IMPULSE seal for its performance, low cost, and environmental benefits.
