Accessories for clarifiers

Fraccaroli & Balzan S.p.A. can offer a wide range of accessories for vertical clarifiers and high rate thickeners.

Oil retainer

Oil retainer

The oil or light floating elements are collected by the retaining ring and sent to a funnel, where they can be easily removed.

Pumping stations for clean water

Pumping stations for clean water

Automatic system, which sends back the treated water to the industrial process.

Screw separators

Screw separators

Screw separators are used to remove the aggregates from waste water.

Covering structures for clarifiers and accessories

Covering structures for clarifiers and accessories

The covering structures are proposed to protect the plants against adverse weather conditions.

PH adjustment with acid or sodium hydroxide

PH adjustment with acid or sodium hydroxide

After the treatment process, the water pH is adjusted with the help of automatic units equipped with probes and pH-meters.

Coalescence separator

Coalescence separator

Separator of suspended hydrocarbons, in accordance to the norms DIN1999 and EN858.

Quartzite and activated carbons filters

Quartzite and activated carbons filters

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.

Static and dynamic mixers

Static and dynamic mixers

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.

Slurry level measure with probe or pressure gauges

Slurry level measure with probe or pressure gauges

This system detects the slurry level in the clarifier and allows to program the automatic slurry discharge.

Slurry extraction pump for high rate thickeners

Slurry extraction pump for high rate thickeners

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.

Waste water feeding pump

Waste water feeding pump

The waste water produced in the processing line is fed to the clarifier by an antiabrasive vertical or submersible pump.

Scraper

Scraper

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.

Pneumatic slurry discharge

Pneumatic slurry discharge

The clarifier is fit with the automatic slurry discharge group, equipped with a manual safety valve and a pneumatic valve.

Clean water storage tanks

Clean water storage tanks

We can supply storage tanks completely in steel or with the bottom in reinforced concrete, on the basis of the required volume.

Flocculant dosage system

Flocculant dosage system

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.

Automatic cleaning system for the cone of the clarifier

Automatic cleaning system for the cone of the clarifier

This system, injecting water, can dilute the slurry when it is very thick in order to facilitate the discharge.

Supervision

Supervision

With the help of the supervising system from remote station, it is possible to control the plants from a distance.

Manual and automatic coagulant stations

Manual and automatic coagulant stations

This station allows to prepare and dose automatically the coagulant.

Manual and automatic flocculant stations

Manual and automatic flocculant stations

This station allows to prepare and dose automatically the flocculant.
