CHEAP AND AUTHENTIC PLATE FILTER PRESS MACHINE AT ROTEC VIET NAM
I, Overview of plate filter press machine
What is plate filter press machine used for?
Sludge filter presses are used to separate solids, fibers, suspended residue in the sludge solution. Sludge presses process sludge faster than old technologies such as drying and settling naturally. At the same time, it helps to reduce sludge treatment time. The pressed sludge is easy to transport, reducing the cost of wastewater treatment and sludge treatment.
What are the popular lines of sludge presses?
Currently, Rotec designs and manufactures 3 main lines of presses: plate filter presses, belt presses and screw presses. Depending on the sludge characteristics, needs and investment capital you can choose the one fits your requirements.
The plate filter press is one of the best mechanical equipment to filter and dry sludge. Users can reuse sludge to make organic fertilizer or remove toxic sludge. In the wastewater treatment system, sludge treatment is an important step before releasing wastewater into the environment. Because the types of sludge in industrial wastewater are very diverse. And each type of mud will have different chemical properties. So depending on the type of waste, Rotec will advise the company on the right type of plate filter press.
Nowadays, most factories, wastewater treatment zones in industrial zones and residential areas have invested to use plate filter press machine to increase productivity and save costs. This is a low-cost machine suitable for many popular businesses across the provinces. Because the sludge presses bring great efficiency, environment protection on handling sludge
II, The role of the plate filter press machine
1) Using a plate filter press machine to reduce labor
Traditional manual sludge treatment takes a lot of manpower to dredge sludge in sedimentation tanks after a period of time the tank is full. Or if renting service is also very expensive and does not ensure environmental sanitation in the factory. Especially, with the food production, chemicals … sludge often smells sour, unpleasant or even toxic. Nowadays, when businesses use plate filter presses, belt presses and other types can handle these types of sludge not only at a much lower cost than the above method but also very safe and tidy and does not harm.
2) Saving space
Manual drying method of sludge always takes away a lot of space of factories, requires the sludge to spread thinly and it is sunny outside to meet the drying temperature. This manual method is very difficult because it depends on the weather, especially in the regions with clear dry and rainy seasons, the drying of mud is a difficult problem. If you build a roof for raining, you will have to pay more money for materials and construction labor.
With the ROTEC plate filter press machine, the tight connection with mechanical sludge compression will completely eliminate any concerns about weather. Sludge is very dry with low humidity after pressing, just use of bag or troughs to store sludge and simply process with the smallest sludge volume. Therefore, using the plate filter press machine presses helps many businesses save a large amount of drying yard area.
3) Filter press machine save costs of hiring professional units and dumping transportation
The plate filter press machine processes the sludge to the driest, at the same time with significantly reduced volume and weight. Transporting wet sludge when renting a truck can be large and take a lot of transportation, which is expensive for businesses. But the plate filter press machine helps the sludge to form blocks with high dryness, the sludge becomes tidy. Therefore, a truck can carry a lot of mud, reduce the number of transportation trips, greatly reduce costs.
Effective sludge treatment is to contain the least water, when dumped it does not affect the living environment, the working environment and sludge is quickly decomposed to return to a normal soil state. Therefore, when using plate filter press or belt press, it helps to reduce the cost of renting a sludge truck.
4) Saving polymer, chemical flocculation
The plate filter press machine greatly reduces the amount of sludge flocculation polymer. This long-term, cost-effective feature brings a lot of efficiency to the enterprise’s wastewater treatment system. Therefore, the plate filter press machine currently designed by Rotec team are really effective and indispensable in large-scale wastewater treatment systems, dehydration, wastewater sludge treatment such as:
- Inorganic sludge treatment (eg semiconductors, metal circuits, rocks and ores …)
- Industrial chemical sludge treatment: bleach, textile, white titanium (TiO2), Calcium Carbonate, AminoAcid, ore industry, metallurgy, plating …
- Sludge treatment in food industry: sugar, beer residue, sauces, drinks….
III, Principle of Operation of Sludge Filter Press Machine And Advantages and Disadvantages of the Machine
The plate filter presses is the leading filter press using the method of opening and closing the entire single chamber filter chamber at the same time. The machine operates continuously and automatically for the sludge that is difficult to filter, difficult to separate.
The slurry press machine works according to the principle of using the pressure of the diaphragm pump to pump the sludge solution through the filter bag onto the plate frames to press the sludge, the sludge is pressed in the form of mud cakes, firm and fast drying. Clean water will pass through the slot of the frame is designed with water taps for each frame. And get out by the trough. This water source can be released to the natural environment or reused. The frame press is pressed in batches with pressing time lasting from 45 to 60 minutes / batch
1) Principle of operation of the sludge filter presses
The current sludge presses have the same operating principle is to squeeze and separate water from the sludge to concentrate the sludge from a liquid form to a dry sludge with moisture content of 25 to 30%. Help the mud after pressed harder. Significantly reduced volume, saves on operation costs and is very easy to terminated. The sludge cake, after being filtered, is dropped into the box to be transported.
Current sludge presses are effective for thickening sludge to the maximum extent. And reduce the volume of sludge to 10 times compared to when in liquid form. The sludge press is an effective tool to help the unit save costs, labor for the treatment of wastewater and sludge.
2) Operating principle of the plate filter press machine
The plate filter press machine is based on the principle of using pressure to separate water from the filter cloth and retain solids, fibers, and residue in the sludge compartments of the plate frames.
Specifically, the hydraulic cylinder system of the machine creates pressure that acts directly squeeze the plate frames together. Then, pump (diaphragm pump or piston pump …) pumped sludge into the sludge cavity of the frame frames. Thanks to the pressure of the pump (from 4-11bar), water is gradually released out, keeping solids and residues inside. Pump continuously until the water no longer drains, stop pumping and release the mud cake.
3) Structure of the plate filter press machine

The parts of the plate filter press are coordinated to operate on a smooth transmission line. The plate frame provides the support system for the whole machine and a place to cover the filter cloth. A motor and a hydraulic machine are the primary sources of movement of the sludge press.
Unlike belt presses, plate filter press machine operate in batches, each batch will be a separate cycle. After the end of this cycle will proceed to the next cycle. The cycle is seamless, the machine operates continuously to produce dry, hard sludge batches. And along with the wastewater was separated from the sludge.
IV, Features Of Plate filter Press Machine
1) Modern plate filter press machine is fully automated, energy saving
The most critical point in filter press automation is that the de-water sludge cake must be water-separated completely. Because the machine uses a single-motion filter bag and a high-pressure pneumatic press air. So the sludge cake after dehydrating can be completely separated. That is why complete automation is possible. And the machine will operate optimally when there are fluctuations in pH concentration or sludge properties.
2) Save human resources, speed up progress
The plater filter press machine has automatic mechanisms such as: separating the sludge, cleaning, washing … It is this automatic design of the machine that shortens the working time. For example: the time it takes for the worker to pull apart the heavy plate frame. Or the washing machine will take more labor and longer than the automatic mode of the press. If the above steps are made by hand, it is very inconvenient for businesses to operate continuously at large capacity.
3) High de-water performance
Thanks to the use of the top feed type and the high pressure press (120 – 210 bar). So the mud cake has a low and homogeneous water content. Moisture after pressing pulp reaches 25 – 30%
4) Safety for workers
The application of the plate filter press machine is very safe for chemical factories, solvents, printing inks, tanning, textile, paint, food … Because the sludge of this unit contains toxic substances. . So when exposed to directly or through the air, it affects the health of workers
5) Long term cost savings
Compared with other types, the plate filter press machine use less polymer (slurry flocculation) about 30%.
The sludge after pressing has a high dryness, and can even be broken by hand.
