C) MOnthly IntervalS
1) Empty the bath and inspect it for signs of corrosion, especially pitted surfaces and flaking
scale. The inside should be wiped out with a rag wetted with 5% washing soda (sodium
carbonate) solution.
2) Screen the medium through a 50 to 70 mesh sieve before returning it to the cleaned bath. This
removes scale, agglomerated medium, char, undegraded polymer and lost parts and helps
maintain a good quality of fluidisation.
D) halF-yearly IntervalS
1) The bath should be emptied, cleaned, inspected and the medium replaced by a fresh charge.
2) Alternatively, if the facilities are available, the medium may be thoroughly washed in several
changes of clean water, washed through a 70 mesh sieve, drained, dried and returned to the
bath where drying is completed by fluidisation and heating at 150°C, until the medium
fluidises in the normal manner. The washing procedure removes acidic residues and
accumulated soluble salts and residues.
Symptoms of neglect should be dealt with immediately. These include: pitting of metallic surfaces,
formation of lumps of agglomerated medium, accumulation of polymer or polymer filler material,
indications of bad or uneven fluidisation, blockage of the fluidising plate and wetness or stickiness
of the medium.
nOte A non-standard version of this industrial fluidised bath is available which is manufactured
from materials that resist the effects of corrosion experienced when processing items contaminated
with PVC and other halogenated polymers. We recommend that this version is utilised in applications
where continued use of PVC is envisaged.
