Introduction

Press water filters are essential tools in industrial and municipal wastewater treatment, providing an efficient method for separating solids from liquids. The technology is widely adopted due to its capability to handle large volumes and produce dry filter cakes. This article delves into the mechanism of press water filters, their working principles, and specific solutions provided by Jinrun Filter Press Company.

What is a Press Water Filter?

A press water filter, commonly referred to as a filter press, is a device used for solid-liquid separation in various industrial processes. It consists of a series of filter plates and frames arranged alternately. These are compressed by a hydraulic system, which exerts pressure to separate the solids from the liquid, producing a filtrate and a solid filter cake.

How Does a Press Water Filter Work?

The operation of a press water filter involves several key steps:

1. Filling: The slurry containing both liquid and solid components is pumped into the filter press. The slurry fills the void spaces between the plates.
2. Pressurization: Once filled, the hydraulic system applies pressure, typically ranging from 100 to 700 psi. This pressure forces the liquid through the filter medium, leaving the solids behind.
3. Filtration: The liquid, known as the filtrate, exits the system through drainage pipes. The filter medium's pore size is critical in determining the efficiency and quality of filtration.
4. Cake Drying and Discharge: Upon completion of the filtration cycle, the press opens, allowing the solid cake to be discharged. The cake typically has a moisture content of around 20-40%, depending on the solids' nature.

Key parameters affecting press water filter performance include applied pressure, filter medium characteristics, feed solids concentration, and cycle time. For example, increasing the pressure typically results in a drier filter cake but may also increase wear and tear on the system.
