Two of the many properties ProMoss™ brings to industrial water treatment are flocculation and removal of scale. Flocculation produces clear water by binding TSS (total suspended solids) together until they fall out of solution. Chemical companies charge a lot of money for flocculants and polymers to accomplish the same task. This function of the ProMoss™ only becomes a problem when there is a large load of TSS and the treated water needs to pass a small orifice like a spray nozzle. In this case it makes total sense to place a 40-100 micron bag filter after the ProMoss™ contact chamber to remove the TSS that ProMoss™ has removed from the water by flocculation. If there are no small orifice critical points in the system, filtration may not be necessary.
ProMoss™ also removes scale regardless of the ionic makeup. Two activities, at the present time, account for this. First, ProMoss™ causes ions in scale to become soluble, and second, it dissolves the organic contamination that glues scale crystals together into a solid.
Over time, the hard scale becomes soft and ends up as sand particles on the bottom of the vessel. Theoretically, if the flows and turbulence in the water are high enough, this removed scale could flow downstream and plug heat exchangers etc. If there is a concern, a filter would alleviate the fear.
One last point, we have heard from customers that treating with ProMoss™ is too effective and they have to empty the filters more frequently. In one factory, so much “crud” was caught in the filters they couldn’t believe it was coming from their water system and that The Moss™ was somehow making the material.
Luckily the process is progressive. The longer the system is treated with ProMoss™ the cleaner it becomes, there is less scale formation and less filterable material.
