COMPANY HISTORY
Fraccaroli & Balzan s.p.a. was founded in 1969 at Pescantina (Verona). From the very beginning of its foundation, the main aim of the company has always been to develop new and sophisticated technologies for waste water treatment and re-cycling plants in industrial processing in addition to dehydration and mud disposal.
Fraccaroli & Balzan s.p.a. with its qualified team of specialized technicians, a commercial and after-sales network service with thousands of plants installed all over the world, presents itself as a privileged intermediary to all companies that require a definite and reliable solution to their recycling problems. Research, innovation, reliability, dynamism and dedication to the customer: these are the qualities that have put Fraccaroli & Balzan s.p.a. At the forefront as a leader in the sector of waste water treatment during the course of its by now 40 years of activity.
APPLICATIVE FIELDS:
MARBLE, GRANITE AND STONE Decantation of waste water and dehydration of mud coming from the industrial processing of marble, granite and stone.
AGGREGATES PROCESSING Decantation of waste water and dehydration of mud coming from the washing of aggregates (sand, gravel) and washing of ready-mix cars for concrete.
READY MIX TRUCK WASHING Waste water recycling and mud dehydration plant for water produced in ready-mixed concrete truck washing.
TUNNELING Decantation of waste water and dehydration of mud coming from excavation, during the realization of tunnels.
IRON AND STEEL INDUSTRY Decantation of the waste water and dehydration of mud resulting from iron and steel industrial processes.
OTHER SECTORS The waste water treatment and mud dehydration plants manufactured by Fraccaroli e Balzan S.p.A. can be used in processing facilities involved in the following productions: cement, porcelainized gres, ceramic, iron material recovery, gravel crushing, glass, concrete, prefabricated panels and iron metallurgy
SOIL WASHING Decantation of the waste water and dehydration of mud resulting from the reclamation process of polluted soils.
CYCLE DESCRIPTION - REF. PHOTO 1
The waste waters involved in the industrial processing are collected into a pit (A) and are conveyed to the decanter by a suitable pump, which works automatically through level probes. In the flocculant station (B) a solution of water and flocculant is prepared, and is subsequently injected into the pipe feeding the decanter (C). The flocculant acts on the solid particles increasing their settling speed. Once the waste water has entered into the decanter, the clean water rises towards the top of the silo and overflows into the clean water collection tank (H), from which it can be sent back to the machines. The mud accumulates at the bottom of the decanter and is extracted by a pneumatic group (D), which discharges it into the homogenizing tank (E). The tank is equipped with an agitator for preventing the settlement of the solids. A double speed centrifugal pump (F) takes the mud out of the tank and feeds the filterpress (G). The chamber-type filterpress squeezes out the residual water still retained in the mud and discharges the dry mud below its structure.
