Reduction of Zinc in Wastewater (Case Study)

Reduction of Zinc in Wastewater (Case Study)

The client of this case study eas one of the leading companies manufactures roofing and deck fasteners.  Operating three shifts, five days a week, it turns out a minimum of 60,000 – 70,000 pounds of screws daily, 325,000 pounds per week.  Contractors and DIY-ers can find its Fasten-Master brand in Lowe’s and Home Depot’s nationwide.

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.
