Morning all,

I need help please.

On our new project we have been told to treat the waste water from washing out of concrete wagons.

I have looked into the Slitbuster (pH unit and roadside unit), but may be coming out as too expensive.

Have any of you guys got any other tried and tested methods please.

Thanks for that, came across that page yesterday also, so I will check with the Project Manager to see if the concrete company will do that.
