At ProChem, our mission is to provide our customers with solutions. More specifically, we want to provide cost-effective solutions that actually solve their problems and allow them to meet their goals.
That mission often requires time and specialization. We've dedicated the past 15 years to a (very) long list of contaminants, industry-specific issues, and customer-specific issues. As a result, we can meet a lot of different challenges here with our extensive (and impressive) catalog of equipment and chemistry. But there are still corners of the market that we have not yet reached. We want to be prepared for those challenges, and we will be with a little help from our friends at ABS Wastewater.
Like ProChem, ABS Wastewater is a full-service water and wastewater treatment company with products suitable for many different industries. Their flagship family of Regenex Wastewater Treatment Systems is ideal for cost effectively removing a (very) long list of organic compounds. Regenex utilizes a high performance, transformative absorbent technology, developed by their parent company, ABS Materials. This media is reusable. it can be regenerated over and over again while continuously treating wastewater. Regenex is specially designed and equipped to handle certain contaminants that are best left to the specialists at ABS Wastewater. That's why we're excited to announce that we're adding Regenex to our solutions offerings.
Through our mutual collaboration, ProChem and ABS Wastewater can be more cost competitive with a quicker turnaround on solutions for our customers. By expanding our respective catalogs to include one another's products, we can reach more industrial facilities. We share the same goal: solve industry's water problems. Together, we are one (giant) step closer. We're proud to have ABS Wastewater's Regenex systems as a solution option, and we are proud to be part of ABS Wastewater's solutions catalog too.
Before we ship a system to a customer site for installation, we test it here in our facility in Virginia. We call it a "wet test." Wet testing includes running water through the system, testing and calibrating instruments, checking for leaks, simulating scenarios, training Technical Services staff, applying finishing touches, and ensuring all the pieces are functional and present before shipping.
ProChem is currently starting up a 10gpm CWP - continuous flow wastewater treatment system at a leading global securities company. The system will remove heavy metals and suspended solids from their waste stream before discharging it. The following images are from the wet testing that was conducted on this CWP system.

After the successful we test, this system was shipped to Utah for installation. The installation and start-up process is now nearly complete. This process includes operations training and dedicated Technical Services staff on site. They are there to ensure that the system is running effectively, that the operations staff is ready to operate it on their own, and that our customer's expectations have been met--before we leave the site.
Many Engineered Wood and Pellet manufacturing facilities experience regular periods of scheduled downtime just to clean their equipment (WESP, centrifuge, piping, etc.). Downtime for scheduled maintenance can be frustrating and cost millions of dollars, especially if that maintenance includes replacing RTO media.
RTO media can be cleaned using hydroblasting and/or caustic based cleaners. That works but only for a few cleaning cycles. It's also expensive. The other repair option for plugged RTO media is replacing it. This can cost millions between the media itself, the labor associated with the replacement, and the downtime for the facility. RTO media replacement and regular equipment cleaning are only two costly maintenance activities. Engineered Wood and Pellet facilities incur many costs when it comes to maintaining their valuable equipment:
Facilities can save on these costly repairs and replacements by preventing contaminants from entering the equipment in the first place. Removing contaminants such as tars, lignins, sodium, and potassium from the water fed to the WESP, for example, prevents any of those liquid fine particles from entering the RTO. This can extend the life of the RTO media indefinitely. Since implementing the CleanWESP treatment program, one ProChem customer has gone 10+ years straight without having to replace their RTO media. CleanWESP is a chemical treatment program designed to remove damaging contaminants from recycle tank water in order to protect valuable equipment and save time. ProChem, Inc. performs a treatability study on the water from each customer site to determine the appropriate treatment program for that situation. The goal of CleanWESP is to protect valuable equipment, saving the customer down time and maintenance costs.
Downstream of a WESP, the RTO can receive a multitude of residual particles from the air, including those found in water vapor. These particles are left behind in the media and can plug it up, causing it to become dysfunctional. Hydro blasting and/or caustic cleaning may clean the media successfully, but it is only effective for a few cleaning cycles--and it's expensive. The other repair option is to replace the media, which can cost millions of dollars between the materials, labor, and plant downtime.
To prevent RTO media fouling, you have to know what's going in to the RTO; that is, you must know the inputs. In this way, you can predict what may linger behind on the media that could foul it and then implement a method of removal prior to the RTO. RTO inputs include both coarse and fine particles. Coarse particles (those over 5 microns) may be dust or liquid droplets. Likewise, fine particles (those less than 1 micron) can be liquid or solid, depending on their makeup. Fine particles are typically formed when vapor cools and condenses into a particle and can include oils, resins, and iron as as a solid. Liquid fine particles such as tars and lignins will be left behind deep within the RTO media as the water evaporates. Some fine particles such as sodium and potassium oxides and others, like chlorides, can cause more damage than plugging. Because they are chemically reactive, they will actually react with the makeup of the media itself at high temperatures. This reaction can cause the media to become brittle. One way to save on costly repairs and replacement is to prevent the inputs from entering the RTO in the first place. Removing or reducing water contaminants such as tars, lignins, sodium, potassium, and chlorides from the water fed to the WESP prevents any of those liquid fine particles from entering the RTO. This can extend the life of the RTO media life indefinitely.
CleanWESPTM is a chemical treatment program designed to remove damaging contaminants from recycle tank water in order to protect valuable equipment and save time. ProChem, Inc. performs a treatability study on the water from each customer site to determine the appropriate treatment program for that situation. The goal of CleanWESP is to protect valuable equipment, saving the customer down time and maintenance costs.
The Engineered Wood & Pellets industry make products such as OSB board, paneling, treated lumber, and wood pellets (burned for energy production). These processes, like all manufacturing processes, use water. All the water that these facilities use is reused back into their process. That's right, the wood industry is very water conscious. These operations utilize valuable equipment like Wet Electrostatic Precipitators (WESP) and Regenerative Thermal Oxidizers (RTO). These units require regular maintenance as excess tars and saps found in the water can gum (sticky seal, like resin) the equipment. It cost as much as $1 million (yes, one million) to replace the RTO media when it becomes fouled. When it is replaced, the plant has to be shut down. That $1 million doesn't include the costs associated with the down time, added labor, or waste disposal... So, the treatment of the water they reuse is a key cost saving factor for these operations, not to mention performance insurance for their equipment. Remember, if the manufacturers are saving, the consumer is too. ProChem, Inc. designs chemical treatment programs that protect the WESPs and RTOs so that the water is usable and the equipment lasts. Here is a case study from a ProChem customer, a Bio pellet manufacturer in Georgia: The customer was incurring high costs associated with maintaining their process equipment. Specifically, they were:
The cause was the poor quality of their water, which contained excess tars, saps, tannins, and lignins. To resolve this issue, ProChem, installed a new water treatment system that utilized a custom tailored chemical treatment program, CleanWESPTM, to remove TSS, tars, and saps while reducing the TDS in the recycle tank water. This provided the customer with cleaner recycle water and clean WESP flush water. ProChem also provided a treatment program for the shutdown water so that the facility could treat and discharge within discharge permit limits (rather than storing it on site).
It has now been over 9 years since the system was implemented, and the customer has not had to replace the RTO media at all in that time. Additionally. their costs and manpower required for routine planned maintenance has been reduced by 80%. Furthermore, solid waste generation has been reduced by 60% - 70% with filter case now at 40% - 50% moisture (as compared to the previous 80%+).
