FILTER PRESS IS OPTIMAL SOLUTION FOR SLUDGE TREATMENT

Sludge must be removed to reduce the volume of water slurry to the lowest possible level using mechanical methods or manually. This is the work necessary to reduce costs for sludge treatment the next stage, as well as the cost of renting the units shipped and sludge treatment professional.

The essential needs which are series of sludge dewatering technologies developed as a filter press, belt filter press, srew press and most recently technology is decanter centrifuges, which businesses are very interested. The technologies can meet and come up with solutions for the enterprise.

What is the best solution for sludge dewatering?

Drying solid filtration is an important criterion for us to evaluate the effectiveness of sludge dewatering devices because the cost of renting the units shipped and sludge treatment are calculated based on the volume of sludge after filtration. If the sludge after pressing achieve drying solid high → low volume →  cost of renting the units will also decrease, respectively, and that the main purpose of the sludge dewatering.

Nowaday, filter press is an effective solution for sludge dewatering. The difference is that sludge dewatering device operations stable, dryness solid high compared with the existing technology with concentration up to 35% along with low operating costs and  aintenance.

OPERATION OF TEFSA FILTER PRESS

  1. Pressing

First check whether the upper limit pointer of electrical contact pressure gauge on oil cylinder is in pressure maintaining range (cylinder diameter is within 20Mpa). Then close air switch, change rotary switch button to “manual” state, and then press “manual pressing” button, pressing plate begins to compact, when the pressure is up to the upper limit of electrical contact pressure gauge, motor stops running automatically.

  1. Auto pressure maintaining

After motors stop running, open feeding valve and start to feed slurry, however it must ensure the feeding pressure not exceed the rated feeding pressure of the equipment, at this moment, filter press is in auto pressure maintaining state, under the function of feeding pressure, it will filtrate slurry through filter medium (filter cloth), when oil cylinder pressure off hydraulic system is up to the lower limit of electrical contact pressure gauge, the filter press will supplement pressure automatically.

  1. Releasing

After finish filtration, push “manual releasing” button, solenoid ball valve powers on and start to perform high pressure unloading action, and after 15 seconds, pressing plate goes backwards automatically, (auto pressure maintaining model that under 25ml pump without solenoid ball valve) and when contacting with travel switch, the motor will stop automatically.

OVERHEAD FILTER PRESS

The overhead filter press has a more simple plate transport mechanism. It is housed between the over head I-shaped beams. This characteristics has the following advantages:

  • Longer life of the transport mechanism with less maintenance.
  • Installation of one sole transport mechanism which avoids synchronization problems.
  • Placement of all transport mechanisms in the cleanest area of the filter press, avoiding contamination and interfernace with the product.

Plates and Cloths filter

  • The Filter Plates:
    • The filter plate material selection is characterized by the mechanical, thermal, and chemical stress. The principle of all filter presses is based on the fact that the necessary pressure for filtration has to be even distributed in the plate system.
    • Experiences show that this basic principle cannot always be kept. Therefore the plate material has to be carefully selected for each case and regarding the mechanical properties, providing a maximum reliability.
    • The polypropylene plates are pressed and mechanically treated in all usual plate shapes, sizes, and configurations. Only in exceptional cases other materials are such as stainless steel, non-ferrous metals, rubber, etc are used
  • The Filter Cloths:
    • All filter cloths are in standard execution, double type with sewed bottle-neck type in one piece for the best and easiest installation.
    • The filter cloth function is to retain the solids in suspension, each filter plate will thus be fitted with its own cloth. Carefully selected according the exact application, this selection will be associated on the cake discharge guarantee
    • Support cloths can also be included in the delivery if requested in order to assist the filter cloth itself, acting as protection for a longer life time, a more effective filtration result, and guarantee the drain of the plate.
