Interest of lamellar decanters in wastewater treatment

Remove sludges in a wastewater treatment plant is an essential step avoiding water eutrophication in the natural environment.

The sedimentation and decantation of sludge helps for water clarification in primary, secondary or tertiary treatment of wastewater.

The lamellar system is speeding up the decantation process and separation allowing a smaller floor area used than a classic decantation with concrete construction.

Our solutions of lamellar decanters

We manufacture stainless steel frames for our decanters and steel or plastic lamellars system that is very compact and easy to use.

When manufacturing, the adjustment between lamellas is controlled to facilitate the discharge and avoid clogging.

There are different kinds of decantation, with backward flow, with cross flow, or co flow.

Each lamellar module works in a way to accelerate the process of separation and evacuation of biological sludge.

We propose solutions of decantation for physico-chemical treatment (primary treatment) and biological treatment (secondary treatment).

The two different treatments have a singular function leading to a common result : separate biomass from water by trapping particles living at the surface by decanting.

For sensitive areas, we provide a lamellar decanter for the tertiary treatment that means the treatment of vulnerable waters to the eutrophication and nitrates.
