All mass finishing processes produce a wastewater stream that in many municipalities must be treated prior to sending it to the sewer. There are many types of treatment options available and the appropriate system for your facility will depend on the requirements of your local municipality.


Basic options include settling tanks and filter paper beds. These systems greatly reduce the amount of ceramic and plastic media residue from entering your facility’s waste stream. More advanced options include flocculation, centrifuges, and membrane filter systems. These options can produce a clear waste stream that can go to the drain or be reused in the mass finishing process.
Settling Tanks and Filter Paper Beds

These are effective at removing undissolved metals and media residue prior to sending mass finishing effluent to the drain. Both operate using the same principle. The effluent pass through a filter media and is coarsley filtered. The filter paper bed offers more flexibility is that diiferent micron paper filter is available.

Flocculation Systems

use a reactant powder to cause the solids in the mass finishing effluent to form a floc. The effluent then passes through a filter media to remove these solids. This process clarifies the effluent enough so that it can be reused in the process or discarded to the sewer. A major advantage of this type of system is that it can produce a near zero discharge from your mass finishing operations.

Ultrafiltration Membrane Systems

mechanically remove solids and dissolved metals by forcing mass finishing effluent through a membrane filter. Fine particles of metal, worn media, and oil are rejected by the membrane and concentrated in the process tank. Water and unused chemistry pass through the membrane and may be reused in the process. These systems present great savings in chemistry and disposal costs.
