TRANSONIC offers On-site recycling system. When
approximately 100 Liters of solvent waste is generated per day. The
simplest form of solvent reuse is termed "downgrading,"
which is the use of a solvent that has become contaminated through
initial use for a second cleaning process. For example, precision
bearings need very high purity solvents for cleaning. The solvent
acquires very little contamination in usage and can be downgraded or
used for less demanding cleaning operations.
More effort is required to recycle solvent that has become heavily
contaminated and the possibilities for both on-site and off-site
recycling or reclamation need to be explored. In vapor degreasing
and cold cleaning, the soil removed accumulates in the equipment.
Eventually the solvent becomes too contaminated for further use and
it must be reclaimed or disposed of via incineration. For on-site
recycling, many different separation technologies are available.
Commonly used separation technologies for contaminated solvents
include gravity separation, filtration, bath distillation,
fractional distillation, evaporation.
On-site recycling :
A company that used trichloroethylene in degreasing was able to cut
its solvent waste from 20 drums a month to five drums a month a 75
percent reduction. Virgin solvent consumption was reduced by 15
drums a month. Formerly, the company removed solvent waste from
degreasers into a storage tank every other day. The stored waste was
transferred to drums for disposal. Now, the solvent waste is pumped
into a holding tank; every two weeks this collected waste is
redistilled to recover as much solvent as possible, leaving only 5
drums per month requiring off-site disposal.
Extra features of TRANSONIC Distillation/ Recovery Units :
- Proprietary designed water separator encased in cooling
jacket for removal of atmospheric water added during
distillation.
- Extra cooling coils for fast distillation of solvent. (Bigger
freeboard Zone)
- In direct heating (Oil bath heating) to avoid excess heating
of solvent which would otherwise disintegrate.
- Effective chilling unit.
- Storage tank. (Optional)
- Air tight lid cover.
- Filter unit (Optional) at input.
- Level indicator.
