400x400 mm Wastewater Filter Press

The filter press has been used for many years in areas such as sludge dewatering, oil dewatering, etc. It is a highly efficient machine used to filter sludge, oil, and similar substances, making it preferred in many applications.

With technological advancements, more practical, more controlled, and fully automatic models have been developed.

It is a special equipment that works on the principle of separating solid and liquid phases, generally used in sludge dewatering, oil dewatering (reducing waste volume, reducing water content in the product), or filtration applications.

In the Filter Press Plates, the watery sludge transferred by the pump is filtered through the cloths, leaving the solid materials in the spaces between the plates as the pressure increases.

At the outlet of the filter press, the solid phase produces filter cake and the liquid phase produces filtrate.

The filtration process is discontinuous; as the plates fill up, the system opens, and the formed filter cake is cleaned. Then the process is repeated.

The advantages of the filter press compared to other dewatering and filtration equipment can be listed as follows.

• The efficiency of sludge dewatering and oil dewatering is high.

• Filter presses require little maintenance.

• It is easy to operate.

• It is compatible with automation.

• It provides high suspended solid removal.

• It has a robust and durable structure.

• Initial investment and operating costs are low.

• The storage, transportation, and disposal costs of the formed cake are low.

• The concentration of the formed cake can be easily changed optionally for capacity increase or decrease.

• The concentration of the formed cake is completely independent of the feed waste concentration.

Working Principle of the Filter Press

The solid-liquid mixture is transferred to the filter press with the help of a high-pressure pump. The solid-liquid mixture is filtered with filter cloths fitted on the filter press plates, and solid particles are collected between the filter plates. The liquid formed as a result of filtration is removed from the equipment.

The filter press plates and the cloths on them, which are compressed under high pressure, must be fed by high-pressure pumps.

The solid materials accumulated in the volume between the filter press plates must be disposed of by opening the plates and cleaning the materials between them.

Features:

• The high-pressure filter press will significantly shorten the entire filtration cycle.

• The membrane filter press adopts TPE and can reach a maximum squeezing pressure of 2.5MPa, which will greatly reduce moisture content, save on drying costs, and increase production efficiency.

• It can reduce power consumption.

• In cross filtration, the flow rate will be small and the pressure will be high.

• The membrane plate uses rubber or TPE.

• It has many advantages: high strength, high squeezing pressure, high usability, and durability.
