Concrete slurry dewatering separates the slurry into solids and clear, clean water. The slurry typically consists of two components: concrete fragments suspended during the sawing or grinding operation, and cooling water.
To increase worker safety, decrease dust emissions, and extend the life of the saw blades, water is injected into them. The grinding machines have a vacuum system built in to collect all of the concrete wastewater slurries, for management and disposal.
How can manage concrete slurry wastewater?
Concrete slurry wastewater treatment typically comprises a wide range of disposal methods. The conventional slurry management method has been to disperse the wastewater down the roadside, in rural areas with vegetated slopes. If this cannot be done because of environmental concerns, the slurry must be cleaned up and removed from the area. Additionally, the slurry must never be allowed to enter an area with a closed drainage system, or one that is ecologically delicate.
The slurry may be transported to a facility for collecting and pond decantation. This makes a sealed compartment where the solids can eventually settle, and the slurry can build up over time. Ponds packed with material are created as a result, albeit the water must often be disposed of.
The last alternative is to collect and transport wastewater from concrete slurry, to a processing plant in watertight haul tankers. The operator must do this off the job site and use different plant designs (typically belt presses or centrifuges). The location will be ready to manage any processed water, storm water runoff, and solids that are transported to landfills, or used for secondary goods (lime). These outlying plants typically have higher operating costs, and demand bigger initiatives to offset them.
Stations for dewatering and portable filter presses
A mobile mounted filter press with slurry and clean water tanks can quickly extract water from the slurry, reducing the amount of 15% moisture solid cakes in the slurry. The remaining clean water is then redirected through a conduit to the grinder. This process offers total control over the slurry product from birth to death.
The Dewatering Station's portability reduces site set-up costs, and because it runs automatically, just a few personnel are needed to operate it.
Recycling Slurry Wastewater
We are discovering that we can't always carry on in the methods of our ancestors, particularly when it comes to the production of concrete and slurry effluent. As quality control standards and environmental limitations increase, we must discover creative solutions to the problems we face today.
In order to meet increasing environmental standards, reduce waste, and lower operating costs in the concrete slurry wastewater management, Netsol Water has created a cutting-edge system for recycling, treating, and disposing of concrete wastewater on-site.
Slurry wastewater is caustic because its pH ranges from 11 to 12. It includes dissolved solids from equipment, cement, and sulphates and hydroxides from cement, as well as derivatives from chemical additives.
The proper disposal of concrete slurry has grown to be a significant problem, but using technologies like slurry separators and solidifiers makes the process simple, affordable, and successful. Contractors can dispose of slurry immediately at the jobsite rather than transporting it back to the shop, to let it naturally dry out.
Using a slurry solidifier to clean up the mess and dispose of the concrete slurry can be very straightforward. An alternative method involves picking up the wastewater with a wet vacuum, or an auto scrubber and pouring it into buckets or drums.
