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 easy to dispose of. This is because the liquid is often mixed with contaminants such as mud, sludge, chemicals, and more. Here’s a list of other contaminants that dewatering filter liners can be used on 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.) cloth to help filter heavy metals and hydrocarbons and 2.) mesh for enhanced dewatering speed and retention of solid waste.
- 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, sand, and more.
- 250-micron dewatering liner: Filters fine sand, greasy waste, industrial waste, and other sludge with large volumes of liquid and particles.
- 400-micron dewatering liner: Ideal for larger solid wastes 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 contaminants easier, meaning you can typically avoid the use of solidification agents, which is a significant cost savings.
- The reduction of waste 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 dewatering contaminants. When choosing one, make sure you pick the right size and pay special attention to the position of the hooks on the container. Also, select them based on the nature of contaminations in your sludge and how quickly you want the drainage to occur.
At Adler Tank Rentals, you can purchase or rent a variety of tanks and containers and find the right dewatering container liners of various micron ratings for a variety of dewatering needs. Our dewatering liners fit directly onto containers using hooks present on either the inside or the outside of the container.
