Ash Pond Materials
Products for Fly Ash Disposal
An ash pond is used to dispose of combustion residue, called fly ash. This "wet method" of disposal requires a large pond to fill with fly ash slurry. The water will eventually drain and evaporate, leaving the fly ash in a contained environment to be reused.
What Materials Do I Need to Create an Ash Pond?
Using a geotextile liner to line the pond will protect the soil from contamination. One of the largest current applications is to the containment of hazardous or municipal wastes and their leachates. Our liners are available in various styles. Some common fabrics we carry are Low-Density Polyethylene (LDPE), High-Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), and Polypropylene (PP).
Our Granite experts recommend implementing a water baffle system in your ash pond. The baffles will allow the flow to be controlled and the entire pond area to be used. This results in better BOD and TSS levels and ensures plants stay within there permit limits and avoid costly shutdowns.
One other recommended option is using Dewatering & Filtration Products. These dewatering bags are ideal for filtering materials on projects and are used extensively on Water Treatment projects (WWTPs), agricultural ponds, aquaculture facilities, pulp and paper mills and numerous industrial lagoons for consolidation of media. This technology is often the most inexpensive economical route to consider for treating a specific sludge / slurry stream.
How Can Fly Ash be Reused?
In the past, fly ash was simply released into the atmosphere, but now it can be stored and recycled. Fly ash is most commonly reused in the following applications:
- Portland Cement and Grout
- Embankments and Structural Fill
- Waste Stabilization and Solidification
- Raw Feed for Cement Clinkers
- Mine Reclamation
- Stabilization of Soft Soils
- Road Subbase
- Flowable Fill
- Mineral Filler in Asphaltic Concrete
- Loose Application on Rivers to Melt Ice
- Loose Application on Roads and Parking Lots for Ice Control
