Fliegl offers effluent solutions
Founded in Germany as recently as 1977, today, the Fliegl Group employs more than 1100 workers, offering an expansive range of transport solutions, from their base in Bavaria.
An alternative solution from TechniPharm presents a cheaper option.
The Ecobag system, developed by Dutch specialist Wiefferlink Group, consists of a contained bladder-type structure which requires only minimal earthworks in the shape of a sump or earth banks for support, and is tethered by a system of retaining straps and ground anchors.
The company claims various advantages: preservation of nutrients, because the sealed bladder suffers none of the evaporation that occurs from open pond structures; no odours, useful if residential areas are nearby; and no entry of groundwater or rainwater.
The set-up is also said to prevent crust formation, and mixing is done by a self-contained stirrer.
The flexible film construction is said to have strong mechanical properties, resists chemicals and is backed by a five year warranty.
Installation costs can be as low as $37/m3 as against a more likely cost of around $60/m3 for a traditional open pond system.
Available in sizes from 1000-10,000 cubic metres.
