Liquid waste presents several challenges for many industrial processes. Liquids are difficult to transport, liquids contaminate work areas and environmental receptors, and most landfills do not accept liquids. On-site solidification with superabsorbent polymers (SAPs) offers the most rapid, safest, and, in most cases, most cost-efficient method for transforming difficult-to-manage liquid wastes into easily managed solid waste.

Solidification of liquid wastes is a widely used waste management method in a variety of industrial sectors. When evaluating different solidification products, absorption capacity is a critical parameter that should be understood before making a selection. Superabsorbent polymers (SAP) feature an absorption capacity that is approximately 75 times greater than traditional absorbents such as sawdust and dried granular corn cobs.

The physical properties of Coal Combustion Residuals (CCR) present many challenges to utility owners and environmental professionals. The waste material (commonly referred to as Coal Ash) is most often captured and stored in open ponds or impoundments, which allow for unrestricted stormwater infiltration, resulting in saturated CCR.

A Step-by-Step Guide for Minimizing Reagent Quantities and Treatment Costs
Superabsorbent polymers (SAPs) are the most efficient available technology for eliminating free liquid and stabilizing saturated coal ash. However, without the proper planning steps, SAPs can be severely over-applied which often leads to unexpected treatment costs and/or underperformance.
The following steps are critical for the successful stabilization of coal ash with superabsorbent polymers:

Superabsorbent polymer (SAP) is commonly used in the manufacturing of ice packs used in the shipping of frozen and refrigerated food packaging.
SAP conglomerates, known as fisheyes, nodules, or gel balls, are common problems in ice pack production.
Fisheyes are denoted as globs or conglomerates of SAP gellant that do not readily hydrate when combined with water.

Rainy weather is often the last thing anyone wants to see on the forecast, whether your plans involve a round of 18, a day out on the boat, or a power plant CCR basin closure.
Water, while vital for life, can be an expensive nuisance when it comes at the wrong time and place.
For electric power utilities, closing a CCR basin during rainy season often result in the following scenarios:
- Missed deadlines
- Excessive chemical expenses, and
- Over-budget labor due to out-of-scope ash drying.
