Effluent in a bag

With ever tightening regulations on effluent storage, containment – whether in open ponds or purpose built reservoirs – is capital intensive.

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.
