The client of this case study eas one of the leading companies manufactures rooﬁng and deck fasteners.

Succeeding in reducing the amount of zinc for OMG included a lot of House Calls – comprehensive tankside support for which the Hubbard-Hall is known – and a fair amount of Red Bull. Hubbard-Hall’s Technical Service Representative David Joyce led a team of wastewater treatment experts in developing a recipe that included AquaPure 100 (a custom-blended inorganic coagulant), AquaPure P601 metal precipitant and AquaPure FW polymer flocculant in liquid form. Early returns were positive; however, degradation in clarity was occurring between the ﬁrst shift and the third.
