Companies working with certain solutions often have to find a way to separate the solid from the liquid. When the time comes, having a filter press is a must. However, choosing the right filter press manufacturers to buy from can be difficult. |
When making the choice, customers must determine exactly what they need. There are a couple of different types of machines to choose from, both performing a slightly different task. They can be either automatic or manual, which work the same with the exception that one is automated while the other is manually operated.
Plate and Frame Machine
The Plate and frame machine, is also known as the membrane filter plate. It consists of plates and frames that alternate. A centrifuge pump helps keep the solids suspended so there is no settling during the process. As the liquid is delivered through the machine, the solids collect on the cloth suspended over frames separating the chambers. When the frame becomes soiled with "cake," the process is stopped and the cleaned liquid is funneled off through collection pipes. The "cake" is removed at the plate and discharges the solids into its collection point.
Recessed Plate Machine
The recessed plate machine works very similarly to remove solids from liquid. The plates in this system are about two to four feet across and have a concave depression in the middle, hence the name. The solution is squeezed through the opening, which has a cloth pulled across it. As before, the liquid goes through and the solids remain, forming a cake. However, in this version, the cake cannot get more than 32mm thick before cleaning. This machine also takes longer to change the cloth and can form an uneven cake.
Filter press manufacturers not only make the machines that separate liquids and solids, but also the individual parts that are necessary to run them. This allows customers to purchase the actual machine and all replacement or repair parts necessary from one company. Parts such as piping, manifolds, hydraulics, and shifters may need to be replaced over time.
Customers may also want to purchase their filter cloths from the same company they received their machine from. Not only are they certain these cloths will work for their equipment, they may also gain additional input on maintenance and how to quickly change these pieces to limit downtime. For those that choose to purchase their replacement cloths elsewhere, many manufacturers have different types and sizes to choose from. It is important to ensure the right product is being purchased at the time of ordering.
Filter press manufacturers are responsible for making not only the machines to separate the slurry but also the parts to maintain that system. While it might be difficult to choose, it is important to select a company that has the right type of press as well as the parts to keep it running long term. Ordering from one company can lower costs and frustration.
