Effluent treatment for a new acid zinc plating and zinc alloys plating (inc. zinc nickel) lines capable of processing 120m2/h. The required discharge limit was 5ppm total metals.
Fruit of a close design development with the plating line manufacturer and with the use of eco-rinse, several stages cascade rinsing, the effluent volume is only 16m3 per day. This enabled the implementation of a 20m3 batch reactor and a specific treatment of zinc alloy stream.
The process developed by Puretech’s chemical engineers associates the use of specific reagents, standard batch reactor and specifically design treatment program. Week in, week out the batch reactor delivers a processed effluent under 3ppm total metal, when the raw effluent is in excess of 100ppm solely on zinc.
This was the very first plant delivered by Puretech Environmental in 2006, the word spread across the road from there and lead to an other exciting project : Thermo-king.
"Puretech's Environmental's performance was outstanding and exceeded all my expectations; I was especially pleased there was no disruption to the company's production operations."
