Coconut Shell-Based Activated Carbons Displayed at AWWA Conference

Siemens’ officials presented the new AquaCarb CX series last week at ACE11 in Washington, D.C.

At AWWA ACE11 in Washington, D.C., last week, Siemens presented the new AquaCarb CX series of coconut shell-based activated carbons, designed for surface water treatment.

Company officials highlighted its aftermarket, retrofit and rehabilitation services at the show, and as funding for new plants and major plant upgrades continue to be an issue for many municipalities, aftermarket solutions are ways that water treatment plants can remain in compliance.

Siemens provides spare parts and equipment that treatment plants need to properly maintain, repair or upgrade their existing facility. Officials can conduct a comprehensive review of the plant’s water treatment equipment and controls, as well as current operating procedures and data, and provide a detailed report with recommendations for improving the water treatment system’s performance.

Some of the locations that have relied on Siemens to meet water quality needs and keep their plants running longer include areas in Pennsylvania, New York and Hawaii. The Huntsville Water Treatment Plant in Pennsylvania converted its existing heavy media upflow clarifiers to the Microfloc Adsorption Clarifier from Siemens, resulting in dramatic reductions in clarifier turbidity levels and a 40% increase in plant capacity.

Additionally, a plant in New York had aging filter systems that had been unable to meet effluent water quality treatment goals. Disinfection by-product precursors and low pH were key problem areas. Officials installed seven Trident systems in concrete basins, and the filter effluent quality is now meeting turbidity and pH requirements.
