Due to the application of parallel plate technology, the DAF FPBC system exerts maximum contaminant separation efficiency.
Ideal for working with large flows and with measures and low loads of pollutants to be removed. They are very high-profile equipment that incorporates internal lamellar circuits to minimize the speed of passage of water in a reduced total volume.
The DAF FPBC flotation system is a high profile separator designed to treat low to medium load wastewater, even those containing low buoyancy particles.
The system is based on the principle of countercurrent flow, through a package of inclined corrugated plates. Water is introduced into the system in a cross-flow configuration that significantly reduces the distance solids must travel to effectively separate. Inside the compact separator, a package of inclined lamellar plates has been installed to obtain a maximum effective float area. The speed of separation is determined by the flow (Q) and the effective surface of the plate (S), therefore, the particles that reach a higher upward speed (by means of micro bubble aeration) than the overflow speed (Q / S), they will be separated.
Due to the application of plate separation technology, maximum separation efficiency is obtained with very low hydraulic ratios, which makes the separators compact and effective.
Dissolved Air Flotation (DAF) technology is used to remove suspended oils, fats, solids, and flocs that do not have enough buoyancy to separate; or where an emulsion of oils and solids (with higher density) requires flotation with air to improve the separation process.
The use of micro-bubbles (30 to 50-micron range) increases efficiency, as smaller bubbles easily adhere to particles of the same size or larger, increasing the overall efficiency of the system.
The DAF FPBC is a high-performance system with distinguishing features.
It includes a single separating movement that rotates against the hydraulic current helping to minimize the distance that floated sludge travels and eliminating the carry-over of solids in the effluent. This solution creates a sludge with a dry solids content 3 to 4 times higher than a conventional system. The result is a reduction in the need and size of any future treatments, such as dewatering or drying, thereby reducing operating costs.
The heavy sludge that settles to the bottom of the system is retained, concentrated, and partially dewatered with the shaftless conveyor system. This allows the operator to control sediment concentration and reduce sediment build-up. The residual sludge is transported to the central discharge point and removed through an automatic pneumatic valve. This discharge cycle has a self-cleaning effect and facilitates that any particle adhering to the walls of the system is released and eliminated with the rest of the waste.
The system is equipped with a saturator-manifold, recirculation pump, and control panel as standard to allow control of the air supply to the aeration module and the sediment discharge valve.
