Steps of the Filter Press Process

Filter presses have evolved over the past decade, but mostly due to the advances in automation. Matec filter presses were the first of their kind to fully automate a filter press. This lead to upgrades in the process due to the automatic setting options. Consequently the operaton of a press has become much less time consuming and easier of the years. Specifically, upgrades such as stronger pumps, better clarifying systems, and consistent sludge development provide a solid foundation for the filter press process. This ensures the press, while going through its sequence of events, operates as unattended as possible and maintains the functionality of the filtration and dewatering process.

In this Water Facts, we will briefly outline the steps to the automated filtration process and how each sequence of events builds upon the next to result in efficient filtration and dewatering and 15% moisture cakes.

How the Filter Press Operates

1. The press has a control box that acts as a brain of the waste water plant. The operator selects Automatic mode to activate the press and begin the de-watering sequence.

2. Sludge is pumped from the bottom of the clarifier into a sludge homogenizing tank. This is done to ensure the sludge is uniform and easier pumped at high pressure.

3. A high pressure pump will send the uniform sludge into the plates of the filter press. The waste material is kept inside the mesh on the plates and water is forced out to a gutter system.

4. Once full, the high pressure pump will stop and the plates will open up. This opening allows for caked material to fall out and be disposed of as solid waste.

5. Once the plates have been emptied, they will begin to retract back to the closed state. Once fully closed, the cycle will begin once again.

What is a Filter Press?

Zinkan has been working diligently to integrate the benefits of the automatic filter press to its customers to ensure that they get the most out of their dewatering process.
