The use of concrete is common on construction sites and a by-product of the equipment wash down processes are waste waters which are alkaline in nature (high pH water). The harmful waste waters must be neutralised before they can be discharged to either sewer or surface watercourse (with appropriate permitting). Where these waters are being reused, neutralisation is recommended to avoid any environmental or human health implications associated with high pH waters.
At OSSO, we understand the importance of treating these waters and the merits of reusing the grey water where possible, so we have designed a modular unit specific to the treatment of concrete wash water.
Modular Concrete Washout System
The OSSO concrete washout system (CWS) is a compact modular offering that allows you to clean down your concrete equipment, neutralise and recycle the wash water minimising off-site disposal and reducing the containment of large volumes of high pH waters on your site.
The alkaline wash water captured in the dewatering chambers is transferred into the treatment tank where carbon dioxide is introduced via an automatic pH correction system to maintain pH neutral water within the tank in readiness for reuse.
