Silt Bags for Water Treatment Plant
Question: I'm interested in using Silt Bags for a water treatment plant. I have recently heard of your products, and would like some information about using them to dewater sludge from filter backwash at our water treatment plant. We typically hire a sludge dredge contractor for sludge removal and dewatering. Will silt bags/geo-bags work as well and be cheaper?
I would guess that the percent of solids at 25%, and a volume is roughly 700 cubic yards (wet) total. I will also need input on how best to get the slurry up and into the bag. Do you also recommend slurry pumps? How do you mix to re-suspend solids prior to transfer pumping?
Answer: Thank you for asking. To answer your first question, yes, the dewatering bags and dewatering tubes are designed to help filter out materials on your site. Bags are typically designed to be more economical and less work than standard dewatering equipment.
Determining the right dewatering product can depend on several different factors. We have a questionnaire that really helps us to determine the proper solution for your project. Please contact us. We'll be more than happy to send you this questionnaire and walk you through selecting the best option for your dewatering project.
Some questions you will find this questionnaire include:
- What Amount of Liquid Needs to be Dewatered?
- Percent of Solids in Situ?
- Will Polymers be used?
- How many gallons will be pumped into the bag per minute?
- How long is the project?
For water treatment plants and long term projects, we typically recommend the use of a dewatering tube. These dewatering products are larger in size and can help contain and dewatering large amounts of materials.
Benefits to using silt bags for water treatment plant include the following:
- Minimal Equipment Required
- Bags can be Run 24/7
- No Complicated Components or Parts
