Slime build-up

1. Check for slime build-up in the stock system.
— treat with one or more biocides.
2. It is sometimes beneficial to use an alternate biocide treatment after a complete boil-out.
3. Check the condition of untreated water.
4. Eliminate “dead” sections of pipe.
5. Eliminate all bypasses that are not essential.
6. Design essential bypasses with a minimum “dead” area.
See Deposit control.
Note: Slime tends to build gradually throughout the entire stock system where it clings to surfaces of pipes, chests, etc. Being somewhat sticky, fibers, fillers, pitch and other materials in the system are often found along with the biological build-up. After some time, the build-up has more cohesive
strength than adhesion strength to the surface where it has collected so it sloughs off and gets distributed throughout the entire stock system. The only control involves a continuous treatment with effective biocides and frequent monitoring to ensure system is working.
