Every industry has certain abbreviations that are beneficial to know when you are shopping around and specifying products; whether it's cell phones, home appliances ... even dewatering solutions (like filter presses).

We asked our dewatering experts for some of the abbreviations and industry lingo that they recommend you know to make the process of sizing and specifying filter presses, a little bit easier.

abbreviations: What it stands for: Why it is important to know:
V Total volume of liquid/solid suspension to be filtered during the daily hours of dewatering operation expressed in gpd (l/d). This will determine how large of a filter press your facility will need to meet your dewatering needs.
tss Total suspended solids in the slurry expressed as a percentage by weight. The TSS will impact what material filter plates and cloths are made of.
sg Specific gravity of the suspension. This number is used to calculate mass of dry solids per day to be dewatered.
c Conditioning chemicals (if required) expressed as a percentage of the dry solids weight of the total batch. This will determine the materials that your filter cloths and filter plates will be made of. Different materials stand up better to different chemicals.
ds Percentage by weight of dry solids in the filter cake. The amount of dry solids (or filter cakes) produced will impact the system you have in place for transporting and storing the filter cakes.
D Filter cake density expressed in lbs./ft3 (kg/l). The density of the filter cake will impact how often it needs to be expelled from the press. If too much heavy cake builds up it can damage the press.
