WHAT IS ELECTROPLATING?
Electroplating is a process that uses electric current to reduce dissolved metal cations so that they form a coherent metal coating on an electrode. Electroplating is primarily used to change the surface properties of an object (e.g. abrasion and wear resistance, corrosion protection, lubricity, aesthetic qualities, etc.), but may also be used to build up thickness on undersized parts or to form objects by electroforming.The most common form of electroplating is used for creating coins such as pennies, which are small zinc plates covered in a layer of copper.
FILTER PRESS TECHNOLOGY
We have invested in a new automated Zinc Line connected to an industrial filter press. This makes for a more efficient and safer working environment. The filter press has a very high performance, particularly when low residual liquid in the solid is desired. The main environmental benefit is that once the liquid has run through the press we are able to recycle the water back through all of our plating tanks.
What is a filter press and how does it work?
A filter press is a piece of equipment used in liquid and solid separation. The filter press separates the liquids and solids using pressure filtration, where in a slurry is pumped into the filter press and is dewatered under pressure. The working principle of filter presses is that slurry is pumped into the machine such that solids are distributed evenly during the fill cycle. Solids build up on the filter cloth, forming the filter cake; the filtrate exits the filter plates through the corner ports into the manifold, yielding clean filtered water. Filter presses are a pressure filtration method and as such, as the filter press feed pump builds pressure, solids build within the chambers until they are completely chock-full of solids, forming the cake. Once the chambers are full, the cycle is complete and the filter cakes are ready to be released.
