BioBrane Biodegrdable Dewatering Bag

Hy-Tex Biobrane™ Dewatering Bags provide an effective way to collect harmful sediments from dirty water pumped out of excavation works (such as foundations, pipe line construction, water, sewer and utility trenches, waterways and lakes) that would otherwise pollute the surrounding environment.

It is a legal requirement to prevent silty water from leaving site untreated, and a finable offence if you do not take appropriate pollution control measures. The SEPA Guidance for Pollution Prevention Works and Maintenance In or Near Water: GPP 5”, and former EA Pollution Prevention Guidelines PPG6, in summary, require that the majority of suspended solids (gravel, sand, and silt) must be removed from site water before it is discharged into a drain, sewer or watercourse.

The standard 1.80 x 1.80m Biobrane™ Dewatering bags has the capacity to trap near 1 tonne of silt and cope with flow rates up to 4,100 l/min, while the smaller 0.90 x 1.20m bags can cope with flow rates up to 1,400 l/min.

Biobrane™ Dewatering bags are uniquely made from a special plant based biopolymer, providing an environmentally responsible solution by using sustainable materials that are fully compostable and biodegradable at end of use.
