New Technology for Grease Control in Sewer Lines
Published on by Water Network Research, Official research team of The Water Network in Business
Aquafix has developed new biotechnology to control fats, oils, and grease in lift stations, pumping stations, and sewer lines that requires little maintenance
Bug On A Rope is a no-netting, slow-release bacterial brick that is bound by oxygen-rich biostimulants rather than an oil-based binder.
Traditional bricks for grease control are made with hardened soap, wax and oils. The same materials that build up in lift stations. This means the bricks have to degrade their base in addition to what is in the lift station. The bricks are held together with a mesh net, which catches a lot of paper and makes them a mess to retrieve.
Story Behind Bug On A Rope
About four years ago a customer of ours, Dan, was using a netted brick from a janitorial supply company, and he said it worked so-so. Aquafix started to study grease deposits from lift stations and what types of bacteria were truly needed. Aquafix found all types of fat, oil and grease (animal fat, vegetable oils, etc), and then asked ourselves how can we bind this bacteria with biostimulants to really activate their growth. It took four years of research and development to come up with the Bug On A Rope, which was named by another customer, Mitch. Both of these customers still use the product and swear by it.
Why Bacteria?
We use the power of bioaugmentation over common degreasers, because degreasers and citrus-based solvents will move the oils straight into the wastewater treatment plant. Fats, oils and grease are very high in BOD and hard to break down, and if they reach your plant, major damage could occur. Naturally degrading the mess and treating upstream will always benefit the rest of the process. There is no better grease control for sewer lines, than Bug On A Rope.
7 Facts about Grease in Collection Systems and Sewer Lines
The harder and colder the water, the harder the grease will set up on the walls.
Generally animal fats are more difficult to break down than vegetable fats with the exception of coconut oils and canola oils.
The thicker the grease is on the walls of a lift station, the more grease in the sewer lines, especially in hilly areas.
Grease coats the lines and creates anaerobic pockets for converting sulfate salts into hydrogen sulfide gas. Sulfide causes rotten egg odors and sulfuric acid corrosion of sewer lines.
The less BOD in a sewer line, the less sulfide gas formation.
1/2 inch of grease in an 8" line reduces your flow by 25%.Then your pumping costs go up accordingly.Grease causes 30% of sewage backups.
