SEWAGE LAGOONS
Many municipalities or industrial facilities rely on aeration to treat, reduce or eliminate sewage. This aeration will typically take place in a single lagoon or a system of ponds.
GeoCHEM can provide the containment to protect the soil and groundwater beneath these ponds. Polypropylene is an emerging material used in this application due to its long term service life and excellent physical properties. Polypropylene provides the following advantages:
Formulated to provide 20 year service life as an exposed membrane.
Excellent tensile/tear strength properties provide strength required in steep ponds of 3:1 slope angle or steeper.
Easy to field seam and repair; No specialized equipment necessary.
Not subject to environmental stress cracking as are some HDPE linings.
Excellent chemical resistance.
