10- FLOT T

DISSOLVED AIR FLOTATION UNIT

PRINCIPLE DESIGN FEATURES APPLICATIONS

The SERINOL flotation unit FLOT T is a longitudinal separator with cross flow.

Micro bubbles of air come to adhere on a particle to form a unit lighter than water, therefore floating.

An especially adapted unit of pressurisation allows the dissolution of air followed by the production of these micro bubbles at the time of the phase of expansion.

The size of the produced micro bubbles (30 to 50 microns) ensures an excellent buoyancy of the matters to be separated.

The dimensioning of the devices is defined to respect a maximum climbing speed of 4m ³/m ²/H.

Flow crosses a packing, located at the head of the apparatus, which supports a fast separation of the largest sedimentary or floating matters.

The slowest particles are separated in the zone of completion.

A scraping system with a temporised motor reducer scraps the floating matters towards a chute of evacuation.

The hydrostatic pressure through a manual valve, evacuates the sediments accumulated on the inclined bottom.

This type of apparatus is particularly adapted to the processing of strongly charged effluents.

DESIGN FEATURES

· 304 stainless steel casing, with internal lamellar pack and anti-swirl surface grid.

· Pressure system:

Controlled injection of air to the aspiration of a pump, which reverses in a tube of pressurisation. This tube is provided with valves to purge the excess of air and to inject the water pressurised at the entry of the flotation unit.

Pneumatic casing including, a flow rate meter and a pressure control component.

· Foam scraping system:

- moto-reductor

- stainless steel conveyor chain with polyethylene rollers

- stainless steel oil gearwheel and driving axes

- shaped stainless steel scrapers and polyethylene blades

· Electric panel:

- manual or automatic control

- motors securities

- adjustable temporisation for the functioning of the scrapers.

APPLICATIONS

- Food industry: slaughter-houses, canning facilities, dairies, separation of greases...

- Paper industries

- Chemical Industries

- Mechanical engineering industries

- Urban effluents

OPTIONAL EXTRA

Rotating sieve SERTAM at the entry - Footbridge with guardrail and ladder – Flocculation unit
