Simple Waste Water Treatment For Concrete Producers. Many concrete production plants generate large amounts of high pH waste water. This waste or process water also contains a high level of dissolved and suspended solids. The waste water comes from rinsing the drums of the mixer trucks after returning from a delivery and from truck washing on ...
If you have already collected the slurry in drums or pits, both AQUAmaxx and ECO-QUICKgel can help with your slurry disposal. Add AQUAmaxx to reduce the amount of waste and just decant the water. Then add ECO-QUICKgel to solidify the remaining concrete slurry. With both products, it is best to mix it in the concrete slurry to create a faster reaction and speed up processing time.
Arrangements can be made to haul concrete from a demolition site to the recycling plant, or, in some cases, recyclers are able to move portable recycling machinery to the plant site. In terms of the overall environment, recycling concrete greatly saves energy compared to mining, processing and transporting new aggregates.
No matter how you look at it, recycling concrete slurry water is a tricky proposition. With the conversation now being more about "how and when" not "if" to recycle water, the question becomes what is the best solution for the slurry created by your company's processes.

Anaerobic digestion (AD) is an economically and politically preferred treatment method for organic waste streams. WTT can supply two different AD systems to be able to find the optimal solution for each specific situation. These are the Dry AD batch process, where waste is digested in large concrete boxes, and Wet AD systems, where the Pulper ...
