The manufacturing process consists of traditional stamping, forming, casting, machining etc of various metals. However, once the pieces are made, they must be finished, usually inside and out and burrs removed. This can be accomplished using mass finishing of course, which also carries with it its own particular waste treatment provisions.
As with any mass or in particular vibratory finishing application, a slow, continuous stream of water is fed into the bowls for lubrication of the parts and finishing media. The water discharged from the process contains metal fragments and degraded media that require disposal. Flushing the water down the sewer is no longer an option due to the metal and other solids content of the effluent, not to mention the possibility of clogged pipes due to the ceramic and plastic media fines. Until recently, disposal was time consuming and very expensive, but recent developments in the use of small centrifuges and/or paper media using filtration units have not only made treatment prior to disposal down sewers possible they have led in some instances to waste water being able to be cleaned to the point it can be re-used in the machines many times over.
BV Products manufactures a range of equipment that provide practical solutions to the problem of treating the waste from mass finishing processes. These include, centrifuges, paper bed /band filters, simple settling/recycling tanks and more comprehensive systems that can be a combination of all the afore mentioned that allow the re-cycling of waste water.
