500x500 mm 15 Plate 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 in filter press machines, more practical, more controlled, and fully automatic models have been developed.

The filter press operates on the principle of separating solid and liquid phases and is a special equipment 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 as the pressure increases, leaving the solid materials in the gaps between the plates.

At the filter press outlet, 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.

• High efficiency in sludge dewatering and oil dewatering.

• Low maintenance needs for filter presses.

• Easy to operate.

• Compatible with automation.

• Provides high suspended solid removal.

• Has a robust and durable structure.

• Low initial investment and operating costs.

• Low costs for storage, transportation, and disposal of the formed cake.

• Capacity increase or decrease can be easily changed as desired.

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

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 fabrics fitted on the filter press plates, and solid particles are collected between the filter plates. The liquid resulting from the filtration is removed from the equipment.

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

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

Features:

• 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.

• Can reduce power consumption.

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

• The membrane plate uses rubber or TPE.

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