TERRAE FILTER PRESS
PERFORMANCE AND RELIABILITY
The Terrae Filter Press is perfect for large and medium-sized production plants specialising in processing aggregates, sand and gravel in quarries and mining or recycling sites.
The name comes from the Latin word for earth. We wanted to remember another central element of our production, a material that we transform from waste into a resource thanks to these extraordinary machines.
The Terrae Filter Press is available in the following model versions:
1200×1200 / 1300×1300 / 1500×1500 / 1500×2000

OPTIONALS OF THE CUSTOMER'S CHOICE
The Cake Dryer is a 100% automatic system for the drying of the cakes of mud through the use of compressed air. The system is similar to the Core Blow; the jet of compressed air is blown into the central hole of supply of the plates, thus allowing a drying of block 20 plates, to have a final cake completely dry.
Cake Washing is a closed-loop system for special slurries containing chemicals. It is usually used in conjunction with membrane plates, allowing clean water to flow into the plate chambers before the bricks are discharged. This process rinses the bricks, lowering the level of chemicals below the threshold that would make them ‘special sludge’ with the associated disposal costs.
The Drip Tray system consists of one or two staggered trays that occupy the part underneath the filter press during the filtration phase and collect the water droplets that escape. Once the filtration phase is over, the trays are then moved by a motor to allow the removal of the cake. This system is designed to prevent some of the water droplets escaping from the cloths from falling on the already discharged mud bricks.
The filter press can be equipped with an automatic plate and cloth washing system. The Real Washing system consists of a valve and piping system on the feed side of the filter press and vent valves on each plate. The feed pump sends clean water to wash out the residual sludge. The system washes the plates 20 at a time. The frequency of the washing cycle is set on the control panel.
The Robo Wash is a fully automated canvas washing system that can be put into operation at the push of a button. The high-pressure sprayer, located at the end of a sliding curtain, runs between each plate and dispenses high-pressure washing water over the entire surface of the canvas, dislodging and removing any build-up of dirt on the canvas.
The Squeezing Membrane system allows better mechanical pressing of the sludge cake. Basically, the membrane is inflated with water and grows in volume by squeezing the sludge that is pumped into the chamber. A variable volume is the main difference to standard plates. The special plate, together with the drainage system, guarantees a drier end product and a more efficient filtration cycle. The draining of the cake also benefits. The material of the membrane can be varied by using different technopolymers depending on the customer’s needs and the material to be processed; they are usually made of polypropylene.
The Torbidity Sensor is placed in the clear water storage tank and consists of a candle gauge (sensor) immersed in water with dissolved particles. Based on the feedback from the sensor, it is possible to determine where to direct the water flow. Using predefined values, if an excessively high turbidity level is detected, the system activates the valves and diverts the water flow from the fresh water tank to the wastewater collection tank, in order to put the water through the clarification phase again.
