Polyethylene HDPE geomembrane LLDPE 1.5mm Geomembrane
Wastewater treatment pond liner
Geomembranes designed for Aquaculture
Geomembranes control the cultured water quality, allowing for higher crop densities,healthier
crops with greater dissolved oxygen content, and improved feed conversion ratios. Higher survival
rates and greater outputs improve profit potential.
Dajin's high-quality, high-density polyethylene (HDPE) geomembranes are high performance
solutions designed for use in aquaculture applications. Our polyethylene geomembranes are
certified for potable water containment. They contain additives
or chemicals that could leach out and impact water quality or harm livestock. They are also robust
and reliable.
Dajin geomembranes can be repeatedly cleaned and disinfected with no decrease in the liner's
performance. Made from the highest quality resin recipes, our highly durable geomembranes have
been used successfully all over the world. They have outstanding thermal and dimensional stability
and are highly resistant to UV degradation. Key benefits of using these high-quality geomembranes
include erosion control, disease and microbiological controls, improved crop quality and a reduced
carbon footprint.
Erosion Control
Our geomembranes offer effective erosion control. The liner eliminates slope deterioration caused by
surface rains,wave action, and wind.The liner prevents eroded materials from filling the pond and
reducing the volume. In addition,costly erosion repair and dredging are eliminated.Dajin's high-quality
HDPE geomembranes offer secure water containment, enhanced quality control, erosion control, and
improved crop quality, and they are kind to the environment.
Geomembrane is very low permeability synthetic membrane liner or barrier used with any geotechnical
engineering related material so as to control fluid (or gas) migration in a human-made project, structure,
or system. Geomembranes are made from relatively thin continuous polymeric sheets, but they can also
be made from the impregnation of geotextiles with asphalt, elastomer or polymer sprays, or as multilayered
bitumen geocomposites. Continuous polymer sheet geomembranes are, by far, the most common
Manufacturing Technique
HDPE Geomembrane liner are made from polyethylene polymer materials by the film-blowing
process.it is most widelyused for solid waste containment (such as landfill liners), mining and
water containment applications.
