How to remove struvite? Struvite Removal Solution
6" pipe from CAFO operation that our Struvite Remover cleared
When looking at photographs of struvite filled piping, clogged valves and screens, and covered surfaces, it always leads to the question, “How do you remove struvite without causing a major interruption?” Struvite precipitation and formation in wastewater treatment plants (WWTP), Concentrated Animal Feeding Operations (CAFO), Food Processing, and many other industries that have wastewater with Magnesium, Ammonia, and Phosphate.
One of the easiest ways to stay on top of a struvite or vivianite problem is to utilize the plant data that you are collecting. Tell signs of struvite formation can include flow changes due to restrictions in lines, pumps and screens, and heat transfer in heat exchangers and anaerobic digesters.
A WWTP had a 14’’ diameter transfer line and noticed it took 45 minutes to transfer sludge when it should have taken 4 minutes. Upon discovering struvite, they hydro-jetted the line which can leave potential growth sites, or if they used a grinder, would have much downtime in both situations. Other options for removal have included using acids which can lead to other issues.
Replacing Equipment, Grinding or Hydro-jetting:
- A lot of downtime
- Labor intensive (High costs!)
- If any struvite remains will grow and accumulate much faster
Using Hydrochloric Acid to remove struvite or vivianite scale:
- Highly corrosive
- Highly Hazardous
- Leads to damaged equipment
Struvite Removal Solution with Struvite Remover STSR
An alternative method for struvite removal that is much easier to administer and control than mechanical grinding, hydro-jetting, and hazardous/corrosive acids is Struvite Remover STSR.
Struvite Remover STSR can be used in many different applications and industries.
- Recirculations for lines, pumps, heat exchangers
- Standstill soaks for lines that can't recirculate, pumps, screens, and other equipment
- Low-pressure sprays for belt filter presses, other walls, and surfaces
- Foaming for belt filter presses, other walls, and surfaces
Struvite Remover STSR is an environmentally safe product that has proven itself time and time again for struvite removal efficiently and cost-effectively. It is very effective at safely attacking and dissolving the struvite crystal (rock) by targeting the magnesium component of struvite.
