Concrete Slurry Dewatering: Methods & Solutions for the Midwest

Concrete slurry is a byproduct of many construction, cutting, or polishing operations. Managing this slurry efficiently is crucial for maintaining compliance with environmental regulations, reducing disposal costs, and protecting equipment. This guide explores how to remove water from slurry and highlights the best dewatering solutions for industries in Illinois, Indiana, and Ohio.

How to Remove Water from Slurry

Removing water from slurry—especially concrete slurry—typically involves separating solids from the liquid phase to reduce volume and increase handling efficiency. This can be achieved through several methods:

• Settling and Decanting: Letting solids settle in a holding tank and draining the water from the top.
• Mechanical Dewatering: Using filter presses, centrifuges, or geotextile bags to remove water more efficiently.
• Chemical Conditioning: Adding flocculants or coagulants to speed up the settling process and improve filtration.

These approaches vary depending on slurry composition, site conditions, and disposal requirements.

What Are the Three Types of Dewatering?

Dewatering methods can be broadly categorized into three types:

Gravity Dewatering

This method uses gravity to settle solids at the bottom of a tank or pit. It’s cost-effective but slow and best suited for non-critical or low-volume operations.

Mechanical Dewatering

Technologies like filter presses, belt presses, and centrifuges rapidly separate water from solids. For concrete slurry dewatering, filter presses are the gold standard—producing dry cakes and recoverable water with high efficiency.

Chemical Dewatering

Chemical agents like flocculants and coagulants accelerate solid-liquid separation. These are often used in combination with mechanical systems to improve throughput and clarity.
