Process water systems treated with a ProMoss™ program, a plant-based chemical free program that utilizes the leaves from a particular species of Sphagnum moss, are producing some dramatic results in fouled systems. The program is demonstrating unique abilties to remove existing deposits by breaking down the organic "binders" that hold deposits together. This is resulting in dramatic cleanup results in systems without the need for chemical and/or mechanical cleaning.
These photos are from a section of stainless steel piping leading into a plate and frame heat exchanger in a tobacco processing plant. The first photo was taken right after the start of the ProMoss treatment program.
Start of ProMoss™ Program
After three months under the ProMoss™ program, the system was opened up for inspection. Deposits had begun to break down and were being removed from the piping surface.
Three Months Into ProMoss™ Program
This program has made a significant impact on the operations of the plant's open air washer systems that clean and condition the plant air. The systems run much cleaner than they did under chemical treatment programs and maintenance requirements have been reduced dramatically. Plate and frame heat exchangers that used to be on a 3-month cleaning schedule have not required cleaning for 18 months now. The photo below was recently obtained of the same piping shown above. This is its current state! All of the deposits have been removed! You can see signs of etching in the stainless steel surfaces caused by past under-deposit corrosion mechanisms. With this destructive process stopped, the plant expects to significantly extend the life of their process water systems.
Current Piping Condition
ProMoss has been a game-changing program for this plant, improving both the reliability and efficiency of its operations. Plant air quality has been improved, maintenance costs reduced, and equipment life in the plant has been substantially extended as previously corrosive conditions have been eliminated.
