Hydro International introduces the GritCup® and SpiraSnail®, a combined solution that achieves low-cost, high-performance grit washing and dewatering, especially when joined with a Hydro grit removal system at the headworks of municipal or industrial wastewater treatment plants. The solution is ideal for new, expanding or upgrading wastewater treatment plants (WWTPs) with a peak capacity of up to 10 mgd, or as a replacement for worn out or ineffective grit treatment systems.
