FPAC

Description

The FPAC flotation equipment is a large surface flotation clarification and cross-flow sludge/water separation system. The system has been designed to treat wastewater streams with a very high load of suspended solids and other contaminants, which require a large flotation surface to retain the separated sludge (up to 40kg of dry matter per m² can be treated).

SIGMADAF technology is used to separate oils, greases, suspended solids and flocculated matter, which do not have sufficient flotation capacity or when oil-solids emulsions (with high density) require air flotation to improve the separation process.

The use of micro bubble technology (30 - 50 microns) increases the separation efficiency. The smaller the bubble, the better it can adhere to the particles, enhancing the efficiency of the system.

Unique system features

The SIGMADAF FPAC is a high performance, high quality system with differentiated features. It includes a unique separator movement that rotates against the water current helping to minimize the distance that the floated sludge travels and eliminating the dragging of solids in the effluent. This solution creates a sludge with 3 to 4 times the dry solids content of a conventional system. The result is a reduction in the need and size of any future treatment, such as dewatering or drying, which consequently reduces operating costs.

Heavy sludge that settles to the bottom of the system is retained and partially concentrated by the shaftless conveyor system. This allows the operator to control sludge concentration and reduce sludge buildup. The residual sludge is conveyed to the central discharge point and removed through an automatic pneumatic valve. This discharge cycle has a self-cleaning effect, and allows any particles adhering to the walls of the system to be released and removed with the rest of the waste.

The system is equipped with a saturator-manifold, recirculation pump and a control panel as standard to allow control of the air supply to the aeration module and the sediment discharge valve. The better the bubble will be able to adhere to the particles, boosting the efficiency of the system.
