STAR-SORB HDD
STAR-SORB HDD is a 25% wood fiber, 75% super absorbent polymer blend. The blend absorbs many times its weight in aqueous solutions, resulting in a stackable solid. STAR-SORB HDD is intended to solidify wet soil, general wastewaters and simple sludge for disposal to landfill or certified special waste site.
Application
STAR-SORB HDD should be added directly to the waste stream in small amounts as it absorbs the liquid portion of the waste. The amount of STAR SORB HDD added will depend on the amount of liquid in the waste to be solidified. Cuttings waste would require a lot less material than lower density liquid waste streams like spent drilling fluid.
Advantages
- STAR-SORB HDD is a high efficiency absorbent that expands in volume by less than 1 %
- Much more effective than fly ash, sawdust or recycled diaper absorbents
- When used properly, waste sludges will pass paint filter test (EPA9095)
- Solidified wastes can be incinerated
- Will not release entrapped liquids after freezing and subsequent thawing
- Aesthetically improved vs pure polymer products
