Keys To Selecting Dewatering Liner Materials
Drainable Container Box Filter Liners or Bags Used In Dewatering Operations
Utilizing the technological advantages of screen and non-woven polypropylene materials, dewatering liners are an effective avenue for draining liquids from sludges while leaving solids for disposal or other uses.
Ideal for use with standard and specialized steel dewatering containers fitted with dewatering liner screens or welded in perforated steel for the most efficient flow through of liquids through the liner and screens and out of the container. Critical Point: Without these screen features, the sludges/materials/liquids may blind the liner off and flow is restricted. See Link At Bottom Of Page For Views of Dewatering Containers.
The selection of the right dewatering container liner material for your application can often be a puzzle with sludges of all types requiring different liner bag materials.
Key Questions
- What Micron Rating Do You Require? Below You Will Find Links To Technical Data Regarding Particle Sizes And Micron Ratings.
- What is the Size (dimensions) Of the Container Box? Important Detail To Size The Right Liner To the Container Box?
- Will The Filter Liner Be Used In A Container With Inside Or Outside Hooks?
- What are your expectations of time and drainage performance?
- Does your container have a side to side or end to end barrier inside the container. That feature would require a different style or configured liner.
- Do you have time for us to send out a test kit for your operation to evaluate the best material and micron selection?
When you call or email us, we’ll offer additional details and ask questions to get to how best to serve your specific application.

Dewatering | Sediment Bags – Technical Details
Dewatering Bags are designed to filter sediment, silt, and sludges by discharging water while containing the suspended solids inside of an on-site, small footprint, dewatering bag.
Dewatering bags use inward pressure to provide enclosed dewatering without the need of a support container.
Standard and Custom Bags Available In A Very Broad Variety Of Sizes And Materials. Bags shown below are examples of larger selections.
Broad selections of fabric material options.
General Details
Flow/dewatering rates will vary dramatically according to soil type.
Sand will typically flow/dewater at the fastest rate with clay flowing the slowest.
-Wet sand weighs approx 120 lbs per cu/ft
Clay can also blind over the fabric in some instances blocking flow entirely.
Clean fabric will flow as follows:
Standard Dewatering Bag @ 90 gpm per sq ft
Reusable Dewatering Bag @ 50 gpm per sq ft
Dewatering Bags are normally allowed to dry in place then cut open and spread/removed with heavy equipment.
TYPICAL APPLICATIONS
Municipal wastewater
Industrial pond pumping and dredging
Agricultural waste pumping and dredging
Waterway remediation and dredging
Power plant cooling tower sludge
Construction and plant turnaround projects
FEATURES
Dewaters without a container
Provides waste volume reduction
Utilizes internal pressure to dewater
Assists in cleaning contaminants from water
Enables dewatering for hard to access areas
Accommodates up to 8″ diameter discharge hose
Contains solids for disposal
Stock and custom sizes available
