If you regularly work with concrete wastewater, you probably already have a concrete wastewater treatment method in place. However, working in the concrete industry requires you to constantly be innovative. You must be innovative with how you dispose of waste (and how much you create) in order to prevent costly fines and environmental harm. Quality control is constantly at the forefront of operators’ minds and environmental regulations must be adhered to. To meet regulations, wastewater must be filtered and treated before it is recycled or dumped. There are a variety of ways concrete operators can utilize different processes to adhere to regulations.

Filter Press

A filter press is used in countless industries, including the concrete industry. It produces very clean water and allows operators to reuse their concrete wastewater. The slurry is pumped through the press where it moves through the filter press plates. As slurry gathers and turns to mud, water is forced through the filters via pressurized air. Choose from automatic filter presses, semi-automatic filter presses, or the portable MudHen filter press depending upon your needs. Filter presses are an ideal option if you need crystal clear water.

Rapid Settlement Water System

A rapid settlement water filtration system is an easy-to-use system that relies on gravity. It is a much more efficient take on a settlement pond (another option for wastewater treatment). The system utilizes inclined plate clarifier technology and automated purges and pumps, therefore quickening the dewatering process and allowing your shop to run efficiently. The clarifier removes 95% of solids from your wastewater, making it perfect for concrete shops. This is a low-cost, low-maintenance solution for concrete wastewater dewatering.

Slurry Silo

The slurry silo is another effective dewatering technique for concrete wastewater. It relies on the decanting process, which consists of pouring liquid into a container without disturbing the sediment. Slurry is pumped into the collection chamber and polymers are added. As water moves down and around the center, particles fall toward the bottom. Particles slowly settle. Some people choose to use the slurry silo along with a filter press for cleaner water. Though less effective, some concrete operators rely strictly on coagulants and flocculants for dewatering.


Some shops opt to utilize a combination of these machines to get the best results. Contact us for a customized solution.
