The Benefits of Recycling Sealant
What is Recycling Impregnation Sealant?
In a traditional impregnation process using non-recycling sealant, typically more than 90% of the sealant is consumed and is not recoverable for reuse. It is washed off the components in the cold wash module and has to be treated as effluent. This adds cost to the impregnation process and increases environmental management costs for the user.
Recycling sealant means that up to 90% of the sealant is recovered and ready for immediate reuse.
How is the Recycling Sealant Recovered?
Instead of being simply washed down the drain and wasted, the sealant is collected from the wash tank and passed through the Ultraseal Sealant Recovery System (SRS) for retrieval and reuse.
Reduced Effluent Costs
Conventional non-recycling sealants emulsify when in contact with water. The resultant cold wash solution is continually weired to drain and requires expensive treatment to make it environmentally acceptable.
Effluent-Free Impregnation with the Ultraseal Water Recycling System*
Ultraseal's latest development is its Water Recycling System for the hot cure stage of the impregnation process. This now allows the whole process to be virtually effluent-free.
The Water Recycling System works by continuously pumping hot water from the hot cure tank to an energy efficient distillation unit where the water is purified before returning to the hot cure tank for re-use.
The Water Recycling System offers many cost savings:
- Virtually Effluent-Free Impregnation
- Less water used
- Less energy required to heat water
- Lower bills for effluent disposal
- No production down-time.
* Only a tiny amount of concentrated waste is produced during the distillation process - less than 2% of the volume in the water tank (dependant on process parameters). During distillation it is separated from the water and collected automatically for disposal.
