Case Study
On completion of each day, the client washes off all equipment, moulds etc and hoses down the floor in preparation for the next. This water, averaging 20m3 per day, because of its contact with cement-based slurry products, contains a high suspended solids content and is highly alkaline. Added to this, the large storage and curing area have a high runoff during rainfall events. This runoff ends up in the same settlement tanks.
This water is a contaminated waste product, requiring routine maintenance in the removal and disposal of silt. The 120m3 settlement tank is a significant health and safety issue.
By installing a treatment system consisting of a treatment tank for pH reduction and water conditioning, a lamella settlement tank to remove solids and a water quality monitoring and correction tank, the water is transformed from a contaminated waste to a safe reusable asset.
This process not only enables the water to be reused in the batching process, but is also within the specification of the discharge consent for safe discharge from site.
As part of the installation of this system, the settlement tank was reduced from 120m3 to 45m3, with safety measures put in place to protect personnel, and a 10,000-litre clean water tank was installed to store clean water ready for reuse.
The system is installed for total automation, using its onboard diagnostics system to report to the site operatives on water quality, consumable restocking requirements and system status troubleshooting.
