ABBCo been manufacturing geo-textile dewatering bags since 2000.  Woven (WSFB) and Non woven geo textile dewatering bags are used either to replace or complement mechanical sediment  removal equipment. 

We exclusive use specially configured geo-textiles for the construction of the dewatering and pump filter bags. Before proceeding please download the Synthetic Industries Technical Bulletin (see info box) to gain an appreciation of their application capabilities and limitations. Material data sheets are also available for download. 

Standard seams are two rows of double stitched 10,000 denier polyester. Depending on product to be dewatered we are also able to seam using upto to 2mm twisted polyethylene and braided kevlar threads.

Application Notes




SI 4x6

1.2 When selecting the most appropriate filter bag for an application it is best to conduct a trial of the bag material using the actual material to be filtered.

We have available text bag packs containing two each of the following:

 SI 4x6 Test Bag

 SI 4x4 Test Bag

SI 1601 Test Bag

The test bags are normally suspended over a collection tray and a sample of the material is poured into the bag.

WDB46-6 6.7m 1x300mm   SI 4x6 11.5
WDB46-9 9.0m 1x300mm   SI 4x6 20

Filter bags should be placed on a fairly level area (filter bags can roll if used on steep slopes). The bags are fitted with hose snouts after inserting the hose (or hose tail) the connection must be secured with a clamp.

Filter bags can handle flow rates in excess of 1920 litres per second. The amount of discharge water which the bag can effectively handle depends on such factors as pump flow rate, amount and type of sediment, degree of slope, and the permeability of underlying surface.

Caution: The filter bags are very strong and water permeable; however, they are not indestructible. Extremely high pumping rates and high sediment concentrations can cause the bag to burst. Monitor bag use to assure maximum performance.
