Fraccaroli & Balzan S.p.A. can offer a wide range of accessories for vertical clarifiers and high rate thickeners.
The oil or light floating elements are collected by the retaining ring and sent to a funnel, where they can be easily removed.
Automatic system, which sends back the treated water to the industrial process.
Screw separators are used to remove the aggregates from waste water.
The covering structures are proposed to protect the plants against adverse weather conditions.
After the treatment process, the water pH is adjusted with the help of automatic units equipped with probes and pH-meters.
Separator of suspended hydrocarbons, in accordance to the norms DIN1999 and EN858.
The filtration plant with quartzite and activated carbons filters mod. FB/DS and DCA is constituted by elements containing filtering beds of alluvial quartzite and high quality granular activated carbons. The filters are regenerated on a time or volume basis.
Before entering the clarifier, the waste water are mixed with a linear static mixer or in reaction tanks, in order to facilitate the reaction of the chemicals.
This system detects the slurry level in the clarifier and allows to program the automatic slurry discharge.
The scraping bridge conveys the slurry towards the center of the thickener. A centrifugal pump is installed under the thickener at the bottom of the conical part to extract the slurry.
The waste water produced in the processing line is fed to the clarifier by an antiabrasive vertical or submersible pump.
When treating very thick slurry, we use a scraping unit. The scraper is constituted by a motor gearbox connected to a shaft, which moves the scraping paddles in the cone of the clarifier.
The clarifier is fit with the automatic slurry discharge group, equipped with a manual safety valve and a pneumatic valve.
We can supply storage tanks completely in steel or with the bottom in reinforced concrete, on the basis of the required volume.
This system can automatically dose the amount of flocculant on the basis of the settling speed of a sample of waste water taken from the clarifier.
This system, injecting water, can dilute the slurry when it is very thick in order to facilitate the discharge.
With the help of the supervising system from remote station, it is possible to control the plants from a distance.
This station allows to prepare and dose automatically the coagulant.
This station allows to prepare and dose automatically the flocculant.
