The Genap slurry lagoon is a Kiwa-certified, excavated pit for storage of various kinds of slurry and digestate. Use of a sophisticated soil balance solution ensures that no more earth will be moved than is to be filled by the banks of the lagoon. Depending on the applicable local requirements, a custom made lagoon will be supplied together with a bottom liner, floating cover and leak detector.
Bottom liner
The slurry lagoon is fitted with one or more prefabricated liners. The most commonly used liners are the PVC Fecatex®, EPDM and (HD)PE films, which are manufactured in accordance with Dutch BRM guidelines. The film liners are welded in our factory, guaranteeing consistent weld quality and enabling installation regardless of the weather conditions. Depending on the earthworks, one prefabricated liner can cover a storage volume of up to about 15000m3. Does it need to be bigger? With field welding, the achievable volume is unlimited.
Floating cover
Covered slurry stores are mandatory in an increasing number of countries. The Genap floating cover is widely recognised as an emission-reducing cover. The slurry is pumped directly between the bottom liner and the floating cover, resulting in a completely closed system. Rainwater can be pumped off the top.
Depending on the annual precipitation, this could provide an effective increase in the usable volume by about 30%. The most commonly used film for this purpose is the Genatex® 850 - a reinforced Kiwacertified reinforced PVC film. But we can also supply alternatives such as the reinforced Firestone EPDM film.
