MEGALITH FILTER PRESS

HEAVY DUTY DESIGNED

The Megalith Filter Press, with its high pressure technology (HPT), guarantees a higher force in the cake pressure. This allows us to achieve a dry cake with a low residual moisture content of up to 10% and to return up to 98% reusable clean water. The new HPT21 BAR system enables filtration at an even higher pressure than before.

Megalith, Matec’s “monolith” with its simple design, consisting of 6 hydraulic cylinders, allows the filter press to be closed, evenly distributing the closing pressure.

The new TT2 FAST allows all plates of the filter press to be opened, 10 at a time, at a speed that makes the TT2 FAST system the fastest opening technology on the market. Simple in design too, because it consists of recessed chamber plates, connected by a chain, and an agitation system consisting of pneumatic cylinders, all standard in the Megalith Filter Press. Structurally robust and all assembled with a fixed carbon steel head at one end and 4 rectangular double-welded tubes for the side beams. All this makes this filter press the only one that can safely reach 21 bar pressure.

The Megalith Filter Press is available in the following models:
2500×2600

Air Gasser® Automatic Shaker

Pneumatic system to guarantee the detachment of the filtering cloth panels created with a series of high efficiency pneumatic cylinders. They lift a stainless steel bar by means of special pivots and then release the plate in order to give it a suitable vertical stress. Our shaker does not wear out and guarantees an efficient vertical shaking of the plate and the complete detachment of the mud cake.

Protection and safety systems :

• Emergency ropes (Standard equipment for every Filter press);
• Stainless steel cover AISI 304 for machine protection and safety;
• Photoelectric barriers;
• Safety gates.

TT2 Fast System

The TT2 System is patented by Matec to solve the problem of sludge discharging opening and closing dead time in filter presses. Thanks to this system that reduces also the length of the machine, the process of plate discharging has decreased from the usual 15/20 min to 3 min for 150 plates. This system guarantees also a 30% increase in productivity and a reduction in operating and maintenance electrical costs, in addition to an easier use of the machine. The TT2 works by opening the main cylinder just once, then it closes, in order to open the first 10 plates. The quick opening of the plates is used to open 10 plates at a time through the back and forth shifting. The two oleodynamic cylinders “TT2 Fast”, installed on lateral bars and provided with mechanical modules. The opening of 2 cylinders works at high speed through the oleodynamic power unit.

Core Blow

The Core Blow system is designed to clean the feed hole, at the end of the filtration process, of residual sludge collected in the diffusion duct through the plates. The filter press is equipped with an air duct inside the moving plate to blow the residual sludge out of the plates at the end of the filtration process. A suitable valve system allows the blown sludge to bypass the pump and be discharged back into the collection tank.

Tilt Sensor

The Tilt Sensor system consists of upper and lower proximity sensors that control the tilt of the last closing plate. In the software that manages the filter press, the delay time between the two sensors can be set. If the second sensor is activated within the set time after the first, the machine can continue its cycle normally. If not, an alarm will be triggered.

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.
