CONCRETE WATER RECYCLING

CWR

Matec is a leader and the leading producer of hi-tech machinery for filtration of water derived from trucks, mixers, pumps and concrete, and generally all water derived from the process. Waste water and sludge treatment arising from washing processes in concrete production sites. Matec designs and manufactures complete CWR (Concrete Water Recycling) filtration plants.
By using the filter press, our plants treat waste water and sludge arising from various washing processes.

Matec CWR plants are designed to maximize the returns of concrete production sites and to recover and re-use washing water, which has
been clarified automatically and without using chemical additives. Thus we can guarantee cutting down disposal costs, also thanks to the production of dry cakes easy to shovel and move.

THE FILTER PRESS

Matec filter press is used in the CWR installations for the mud dehydration. The machine is completely automatic, for the opening and closing of plates, the washing of cloths and plates and their shaking, to guarantee that no mud remains attached to the cloths. Through the dehydration process, we obtain clean water that can be reused for washing mixers and concrete recovery units (screw separator or dewatering screen) and to obtain dry cakes easy to be disposed of. MATEC, through its CWR plants, can recover concrete at the end of its working cycle.

CONCRETE RECOVERY UNIT

SCREW SEPARATOR
The screw separator is used to separate aggregates, which will be washed during this process, from water, which still contains the finer particles and is ready to be purified by the filter press. Recovered aggregates are piled up at one end of the screw separator, ready to be reused in the concrete production cycle.

WHAT MAKES MATEC THE BEST SOLUTION FOR YOUR BUSINESS

PRESSURE
MATEC is the only 100% HPT company using pressure up to 21 and 30 BAR.

 

CAPACITY
We design and build plants to process from 0,5 to 100 m3/h, every plant is automatic and customized.

 

HIGH QUALITY
Matec only uses top brands: Siemens and Allen Bradley for the electrical part, Bosch Rexroth for the mechanical part and feeding pumps 100% made in Italy.

OPENING TIME
The TT2 patented system reduces discharging times of big machines from 15/20 minutes to less than 3 minutes.

 

AUTOMATION
MATEC produces only 100% automatic and hi-tech plants.

 

WARRANTY AND ASSISTANCE
MATEC has a technical office with 5 engineers dedicated to blueprint design, project engineering and the providing of different platforms, 1 dedicated engineer during installation, 10 technicians for the plant assembling and start-up, and for the after-sale assistance within 24/48 hours.

100% AUTOMATIC SYSTEM
FROM 2 TO 200 TRUCKS AND MIXERS
MORE THAN 300 INSTALLATIONS IN THE SECTOR

HOW IT WORKS

The mixers/trucks (1) are washed and the residue is discharged into the screw separator or the dewatering screen. The screw separator, (2) or the dewatering screen, recovers washed material. The recovered material is ready to be reused (4). The dirty water (3) is stored in an external tank ready to be filtered. The dirty water is agitated in the tank.
The dirty water is pumped directly into the filter press by an HPT pump (5) without adding flocculant and without being clarified. The filter press (6) filters the water by retaining all solids, returning completely clean water (7) ready to be reused in the production cycle. The filter press produces dry mud cakes (max 15% of residual moisture) completing more than 5 cycles per hour and reducing sludge volume by 85%.
