Types of Filter Press Used for Wastewater

Wastewater treatment plays a crucial role in maintaining environmental sustainability. We provide an overview of various types of filter presses used for wastewater treatment.

Filter press is an essential equipment for wastewater treatment. It effectively separates solid particles from liquids, ensuring cleaner water discharge. This article explores different types of filter presses for wastewater treatment and their working principles.

From plate and frame filter presses to membrane filter presses, each type offers unique advantages and is suitable for specific applications. Understanding these types can help industries and municipalities make informed decisions when selecting a filter press for wastewater treatment.

Filter Press for Wastewater Working Principle

Plate and Frame Filter Press:

The plate and frame filter press is one of the most common types of wastewater treatment. It consists of alternating plates and frames with filter media in between. The wastewater is pumped into the press, and the solids are retained on the filter media while the liquid passes through. This type of filter press is suitable for applications where the solid content is high.

Recessed Chamber Filter Press:

The filter press is another widely type for wastewater treatment. It has recessed chambers between the plates, allowing for higher cake volumes. The wastewater is pumped into the chambers, and the solids are retained while the liquid is discharged. This type of filter press is suitable for applications with high solids content and requires efficient cake washing.

Membrane Filter Press:

The membrane filter press is a more advanced type for wastewater treatment. It includes an additional membrane layer between the plates. The membrane can exert pressure on the cake for further dewatering. This type of filter press is suitable for applications where desire maximum solids removal.

Belt Filter Press:

The belt filter press is a continuous operation filter press for wastewater treatment. It consists of a series of rollers and belts that continuously squeeze and wash the sludge. The sludge is fed onto the moving belt, and the solids are retained while the liquid is drained. This type of filter press is suitable for large-scale wastewater treatment plants.

Centrifugal Filter Press:

The centrifugal filter press is a unique type that utilizes centrifugal force for dewatering. It consists of a rotating drum with filter media. The wastewater is fed into the drum, and the solids are retained on the filter media while the liquid is discharged. This type of filter press is suitable for applications with high solids concentration and requires continuous operation.

Conclusion:

Choosing the right type of filter press for wastewater treatment is crucial for efficient and effective solid-liquid separation. Plate and frame filter presses, recessed chamber filter presses, membrane filter presses, belt filter presses, and centrifugal filter presses are popular in different applications.

Each type offers distinct advantages and is suitable for specific wastewater treatment requirements. By understanding the working principles of these filter presses, industries, and municipalities can make informed decisions and achieve optimal wastewater treatment results.
