Sludge, a viscous mixture of liquid and solid components, is generated by essentially all industrial and municipal wastewater treatment facilities. When sludge must be periodically removed in order for plant maintenance crews to conduct repairs on process equipment and concrete holding basins, superabsorbent polymers (SAPs) are the safest, fastest, and most efficient choice to convert wet sludge to dry stackable solids.
The new coronavirus epidemic, COVID-19, which originated in Wuhan China, causing severe respiratory illness, has brought a heightened level of both awareness and panic to the general public regarding the spread of viruses and infections in general. This only adds to the pressure hospitals and other healthcare centers have been under to reduce Hospital Acquired Infections (HAIs), which, according to the Centers for Disease Control and Prevention (CDC), affect roughly 1 in every 31 hospital patients across the United States.
Have you ever wondered how those thin pads under your ribeye steak absorb and hold so much liquid? Yet a similar size paper towel can only absorb a fraction of the same volume and releases the liquid when any pressure is applied.
Liquid waste streams such as wastewater treatment sludge (biosolids), coal combustion residuals (coal ash slurries), horizontal direction drilling (HDD) mud, and dredged sediments are challenging to manage for many reasons. Regulatory restrictions on liquid waste disposal require free liquids to be absorbed, or solidified, prior to acceptance at landfill facilities. The absorbent material that is selected can impact the landfill’s leachate management costs, the landfill’s longevity, and the water quality in groundwater and surface water in the vicinity of the landfill. Superabsorbent polymers (SAPs), one of the EPA’s few accepted absorbent materials, help landfills minimize leachate management costs, mitigate environmental risks from leachate leaks, and maximize landfill life.
