What Can CleanWESPTM Do For You?

Prevent media fouling of the regenerative thermal oxidizer (RTO) and contaminant buildup in the wet electrostatic precipitator (WESP), with ProChem, Inc.s' tailored chemical treatment program to treat the recycle tank water. CleanWESPTM platform can remove both particulate and inorganic compounds that can lead to diminished RTO/RCO bed life such as potassium oxide, silicone dioxide, and more.
This prevents harmful contaminants such as tars, tannins, and lignins from entering expensive WESP and RTO equipment and piping saving thousands of dollars in maintenance costs and downtime.

A Total Water Management Strategy


Increase Production Time

For every minute of maintenance downtime, the facility is losing valuable production time. The production process, unfortuantely, is dirty and over time particles plug up the media and build up in the WESP causing reduced efficiency and higher energy usage. Additionally, the particles can be introduced into the RTO, RCO, or biofilter causing irreparable media fouling or poisoning. The CleanWESPTM chemical treatment program prevents these harmful contaminants from entering expensive WESP, RTO equipment and piping allowing the plant to continue in production mode.



Reduce Operations and Maintenance Costs

While hydro-blasting and caustic cleaning can clean the equipment and media successfully, these are expensive and are only effective for a few cycles. Replacement of RTO media, or poisoned RCO media, costs millions of dollars for the media alone.


Prevent Unscheduled Downtime

Planned and Unplanned downtime is expensive. CleanWESPTM programs and equipment significantly reduce the cleaning time necessary for the WESP. Typically a dirty WESP can take 32 labor hours to clean. With CleanWESPTM the cleaning time can be reduced to just four (4) hours. If the cleaning is performed twice a month, this means you can gain two extra shifts of production a month.


Protect Emission Control Equipment

The following particles can be found in the water vapor and become trapped inside the Wet Electrostatic Precipitator (WESP) and the Regenerative Thermal Oxidizer (RTO) media. This can plug up the equipment and media, even causing it to become brittle and dysfunctional.

  1. total suspended solids (TSS)
  2. total dissolved solids (TDS)
  3. high chlorides
  4. sodium oxide
  5. potassium oxide
  6. lignins
  7. tannins
  8. terpenes
