The Wide World of Superabsorbent Polymer Compatibility

The average consumer encounters SAPs on a daily basis, often without realizing their presence. SAPs are used in baby diapers, absorbent pads for food packaging, in hot/cold gel packs, feminine hygiene products, cat litter and more. SAPs also play a role in solidifying and rendering liquids generated by medical procedures as non-"red bag waste." In addition to the consumer goods and medical markets, SAPs are compatible with a long list of construction and industrial process wastes.

SAPs are also widely used to safely and efficiently solidify the following waste streams:

  • HDD drill cuttings, spent fluid, spoils
  • coal combustion residuals (coal fly ash and bottom ash)
  • wastewater treatment sludge and biosolids
  • water treatment sludge (alum sludge, etc.)
  • flue gas desulphurization waste
  • oil and gas drilling fluids and cuttings
  • oil refinery sludge
  • mine tailings
  • dredged sediments
  • petroleum tank bottom sludge
  • retention pond muck
  • saturated or wet soil
  • sandblast media
  • paint rinsate
  • remediation site waste
  • highway grinding waste
  • combined industrial liquid waste streams

Superabsorbent Polymer Basics:

  • Superabsorbent polymers are the fastest, easiest, safest, and most cost-effective option for managing liquid waste. Solidify most waste fluids in minutes resulting in reduced processing time.
  • SAPs require no special equipment. A standard excavator, backhoe, or skid steer can be used to thoroughly mix SAPs with waste fluid.
  • They require no special equipment. A standard excavator, backhoe, or skid steer can be used to thoroughly mix SAPs with waste fluid.
  • SAPs are safe to touch, require no special PPE, and prevent leaching of harmful liquid waste contaminants into landfills and the natural environment.
  • SAPs feature the highest absorbency of any commercially available technology, which allows them to absorb large volumes of liquid with a small volume (or dosage rate) of SAPs. SAPs are typically applied at dosage rates of 0.5% to 1.5% (by weight), compared to dosage rates of up to 200% for traditional absorbents, such as sawdust. The importance of a low-dosage rate for solidification reagents is realized transportation and disposal costs that are impacted by the weight of reagent that is transported and disposed of along with the waste.
