Dewatering Filter Liners – A Solution For All Your Dewatering Needs

Dewatering is the process of removing excess groundwater or surface water from a job site. It is typically the very first step in preparing a site for construction-based applications and is also carried out routinely in various other industries and applications such as in manufacturing, mining, pipeline, and disaster relief—to name a few.

In all these industries, though, it isn’t often that the liquid that has been dewatered is clear and ready for disposal. This is because the liquid is often mixed with soluble chemical contaminants that are not readily removed by filtration and solids capture. Here’s a list of other process candidates that dewatering filter liners can be used to capture both suspended and settled solids during the dewatering process:

  • Municipal sludge
  • Grit and screenings
  • Industrial sludge
  • Paint sludge
  • Cooling tower sludge
  • Tank sludge
  • Drilling muds and frac sand
  • Sump cleaning sludge

There are a few methods that can be used to get rid of these contaminants. Depending on the type of sludge, the easiest and most convenient is to use dewatering box liners. The purpose of these liners is to filter out the contaminants and separate them from the liquid being dewatered at the job site.

Various Types of Liners to Solve Unique Dewatering Needs

There are various types of dewatering container liners that can be distinguished based on the materials used in their construction, the level of filtration they provide, and the type of container they fit.

  • There are two popular types of materials used to make dewatering box liners:
    1. Non-woven cloth to help filter finer particle sizes down to 100 microns
    2. Geo-textile mesh for enhanced dewatering speed and retention of larger, coarse particle sizes
  • Dewatering liners are available for most standard container sizes. There are purpose-built options available too, such as roll-off dewatering liners. If required, these liners can also be custom-built for containers with unique dimensions.
  • Level of filtration is the distinguishing parameter of dewatering liners. The most common options are:
  • 100-micron dewatering liner: Used to separate wastes such as grit, soil, industrial sludge, fine sand, and more.
  • 250-micron dewatering liner: Filters medium to coarse sand, greasy waste, industrial waste, and other sludge with large volumes of liquid with high solids loadings.
  • 400-micron dewatering liner: Ideal for high solids loaded wastes with larger particle sizes such as municipal sludge, paint sludge, drilling muds, and fracking sand, among others.

Why Are Dewatering Liners an Ideal Choice?

From convenience to cost-effectiveness, speed and simplification of the entire process, dewatering liners offer a few advantages. Here are the most significant reasons why you should opt for them:

  • Dewatering bin liners are quick and very easy to install, saving you time and effort.
  • Most waste minimization can be executed on-site using dewatering liners, making the entire dewatering process more efficient.
  • Using a dewatering liner also makes disposal of the dewatered sludge easier, meaning you can typically avoid the use of solidification agents, which is a significant cost savings.
  • The reduction of water weight means the cost of disposing the waste at a landfill decreases.
  • Saves on washout costs of the container after dewatering is complete.

Dewatering container liners are extremely simple, quick, and cost-effective solutions for separating solids contaminants from the liquid phase. When choosing the dewatering liner, make sure you pick the right size by selecting them based on the solids loading and particle sizes in your sludge and how effectively you want the drainage to occur.

At Ironclad Environmental Solutions, we have a variety of rental tanks and roll off rentals which would work with the right dewatering container liners of various micron ratings for your dewatering needs. Our dewatering liners fit directly onto containers using hooks present on either the inside or the outside of the container. We also have rental pumps available, with flow rates up to 2000 GPM, to help facilitate dewatering.
