Geotextile dewatering bags have been a construction industry standard for several decades. Erosion control supply companies often recommend them as a solution to achieve clean water for discharge compliance on project sites. The bags are effective at containing coarse sediments from pumping activities. They are not very effective at capturing fine particulate matter and often require additional measures to produce clean water that meets compliance limits for stormwater discharge activities. The inclusion of polymers in the dewatering process can effectively treat the fine particulate matter and produce very clean discharged water. Standard practices have introduced the polymer into the bag during pumping activities. The idea is that the polymer will react with the sediment laden water and be retained in the bag. Unfortunately, this often results in the bag becoming severely clogged. This restricts pumping flow rates and accelerates containment failure of the geotextile bag. Contractors must then use many more bags at a reduced flow rate to treat the needed water volume. An alternative method for polymer application is to introduce it after passing through the geotextile bag. The bag is then used as a pre-filter and a way to convert concentrated flow into sheet flow. A simple containment is built around the dewatering bag and is used to direct the water flow over polymer blocks for treatment. This treatment consists of a soil-matched polymer (optimal results), mixing area with contact time, and a particle capture area to remove polymer treated sediment.
