What is FROG, and why is it a problem?
FROG stands for fats, rags, oils, and greases. Sewer overflows and backups, odor, and many other issues to the environment are a few of the reasons why FROG is a problem.
Most wastewater collection system blockages can be traced back to FROG as the cause. Blockages in the wastewater collection system are serious, causing sewage spills, manhole overflows, and sewage backups in homes and businesses.
Large amounts of FROG in the wastewater causes decreased pipe capacity in the collection system, resulting in increased maintenance costs and premature pipe replacement.
FROG also can cause treatment issues at the wastewater treatment plant. In a liquid form, it does not appear harmful. As the liquid cools and the grease congeals, it creates thick grease mats on tanks, piping, and equipment, which causes treatment problems and higher maintenance costs. In addition to fats, oils, and grease, rags and flushable wipes also cause blockages in pipes and equipment.
