AQUACULTURE POND LINERS

For efficient aquaculture farm management and water quality controls, hatchery, grow out ponds, tanks and raceways performance are significantly improved by the use of Geopoly HDPE geomembrane plastic pond lining system. The benefits of installing a HDPE geomembrane plastic pond lining system includes easier pond maintenance and reduction in operating costs; better water quality control, reduces turbidity and risks of disease; effective water leakages and bund slope erosion control; saves time in pond preparations between harvest; reduces sludge, waste and sediment contamination at pond
 

bottom; ultimately leading to better farm performance and profitable crop harvests.

The recommended HDPE geomembrane liner material thickness to 100% line an aquaculture pond is 0.75 mm. The customer may consider using HDPE geomembrane liners of 0.30 mm or 0.50 mm thickness with 7.10 metres standard roll width, if the requirement is to cover the pond bund and slope only. For slope protection purposes, an alternative would be to use Geopoly LDPE of  0.20 mm to 0.30 mm thickness with available roll width ranging from 0.75 metres to 7.00 metres.    

 

 

FLOATING COVERS, COVERED LAGOONS AND BIOGAS UTILIZATION

Issues of contamination from organic wastes and factory sludge has arisen from increased agro and factory production.

The effluent or discharge from such wastes and sludge lagoons are consistently being monitored by the Municipal Authorities and Environmentalists for a proper waste management, treatment and disposal system. There is a concern of ground water and river contamination by such untreated leachates and waste by-products.

Geopoly HDPE geomembrane lining systems are useful to line holding ponds, sludge ponds, aerobic or anaerobic treatment ponds and evaporation ponds in waste treatment facilities.


Geomembrane liners are also used as floating covers or cappings onto wastes lagoons or sludge pits to reduce air pollution, foul smell and to control flies, rodents and pests. HDPE geomembrane floating covers may be utilized in tandem with a biogas or methane gas collection facility to generate electricity.
