THE AMF SYSTEM
The system consists of a circular tank divided into four main sections as follows:
1. central inlet blending section containing the distribution system into the flotation tank;
2. circular ring flotation basin with low water profile, to let an even distribution of the water from the centre towards the periphery of the tank, following a pre-calculated dynamics, that allows the optimal separation of the solid particles in a very short processing time;
3. floated solids collector trough, that guarantee high consistency of floated sludge due to exclusive dual scoop design for uniform recovery of floated material:
4. settled sludge discharge troughs.
Recycle pressurization DAF systems utilize a portion of the effluent water in the process.
From the tank, processed liquid is pumped into the pressure vessel where air is injected and is allowed to dissolve into the solution.
This pressurized recycle is now injected into the waste water line running to the AMF tank.
At a point determined to be most efficient, a pressure control valve reduces the liquid pressure, allowing the entrained air to be released from solution, thus creating fine bubbles.
The imbalance of density between the air-water mass and the liquid further away creates a vertical upward mass flow – which carries waste particles to the water surface.
On the way, air bubbles attach themselves to the particles and upon arriving at the surface the particles is supported and maintained by the bubble. At the water surface, the air flows radial away – pushing the solids clear.
The floated solids are periodically removed by a scraping mechanism which moves round the surface of the liquid.
The clarified wastewater flows via a submerged outlet into a weir chamber prior to discharge. The telescopic valve controls the depth of liquid in the flotation tank.
Availability of several automatic and advanced process control options to optimize costs, efficiency and minimize the operators presence at the plant running.
