The buildup of grit and debris (hair, sand, rags etc.) can
negatively impact the operation of a digester by reducing its
retention time and not allowing the full proper digestion process to
take place. This grit and debris is usually not able to be
removed using the sludge pumps that draw the biosolids from the
digester, and that which is able to be removed is very harsh on typical
pumping and heating equipment that is in place, causing higher
APG has the experience and the technology to safely and efficiently
clean all types of digesters. With our advanced pumping
systems, screening equipment, and operator knowledge, we can handle
any digester or tank.
All of our operations personnel who work on digester projects are
trained in confined space entry & rescue as well as any other
safety training required. We comply with all jurisdictions health
and safety policies regarding confined space entry. Air quality is
continuously monitored using air monitoring equipment, and emergency
rescue equipment (e.g. SCBA) is on site should it be required.
All of our equipment that enters the digester is Hazardous Location
Rated for such an environment.
