Muffin Monster Protects Progressive Cavity Pumps, Enhances Productivity in Biogas Application
Biogas facilities commonly utilize a wide range of organic feedstock materials include food waste, manure, and agricultural waste. Feedstock is processed in a sludge or slurry form and is moved around the facility with some type of sludge pump. Progressive cavity pumps are one of the most common options for a sludge pump due to their ability to move viscous liquids.
The organic feedstock is often comprised of mixed waste and can often include unexpected debris like large, tough pieces of inorganic debris such as metals and plastics. This inorganic material, if left uninhibited, can clog a sludge pump or pipeline within the anaerobic digester systems and cause the process to breakdown. This tougher debris in feedstock can be extremely problematic for progressive cavity pumps that are susceptible to damage within the pump’s costly rotor or stator components.
In 2013, a biogas facility in Catalonia, Spain was experiencing these very problems. The mixed organic waste coming to the plant had hard inorganic solids that were never expected in the planning stages of the facility. The debris was finding its way to the progressive cavity pumps and wreaking havoc. Plant personnel worked with Protech Continental, the exclusive JWC Environmental distributor in Spain, to assist in solving the problem. The team was able to devise a long-term solution that would precondition the biogas feedstock, protect the sludge pump, and keep the biogas system running smoothly.
Problem: Damage to Progressive Cavity Pumps
Low production and high maintenance in biogas production facility. Loads of organic feedstock contained inorganic solids including bolts, plastics and rope that caused excessive wear on progressive cavity pumps.
Solution: Monster Grinder for Sludge Pump Protection
The introduction of a 30004-B150 Muffin Monster from JWC Environmental was just what the plant needed.
The Sludge Monster steps in to save a water reclamation plant in Texas after suffering from many years of severe plugging and pump rebuilds. With their previous macerators, the plant had to interrupt the system 2 – 3 times a day to cut through rags, hair and debris.
According to the Plant Maintenance Superintendent, “It’s been a blessing for the last six months” having installed the Sludge Monster.
Muffin Monster Takes Over When Macerator Can’t Cut It
The Coeur D’Alene Wastewater Treatment Plant has been in operation since 1939. Since then, the facility has been overhauled significantly to keep up with demand, area growth and innovations in wastewater treatment technology. The treatment plant was having continual problems with two sludge macerators, during design someone misread the max PSI rating as 150 — while the macerator’s true max pressure rating is 30 PSI. Eventually, one of the macerators exploded and flooded the underground pump area with sludge.
It took about 12 hours for operators to clean up the mess after the macerator exploded. The crew pulled a Muffin Monster® grinder from their back-up stock, and it took care of the sludge immediately. Impressed with the performance and quality of the Monster grinder, the treatment plant manager requested approval to purchase three additional 10K series Muffin Monsters.
