Wastewater Treatment – Arsenic Removal

Arsenic can be found in the wastewater from electronic manufacturing, silicon semiconductor manufacturing, communication and optical manufacturing utilizing gallium arsenide, and in the wastewater discharges from ethanol production plants.  Municipal wastewater treatment plants are also required to meet minimum Arsenic discharge levels.

Arsenic has been linked to cancer of the bladder, lungs, skin, kidney, nasal passages, liver, and prostate. Non-cancer effects can include thickening and discoloration of the skin, stomach pain, nausea, vomiting; diarrhea; numbness in hands and feet; partial paralysis; and blindness.

To protect an estimated 13 million Americans, the U.S. EPA has  lowered the acceptable limit for arsenic from 50 ppb (parts per billion) to 10 ppb, and water systems had to comply with the new rules by January 2006. 
Siemens offers a number of solutions, including granular ferric hydroxide, to help communities meet new arsenic removal guidelines. Additional technologies include:

  • Granular Ferric Hydroxide Systems
  • Wastewater Aerators
  • Tertiary Wastewater Filters
  • Membranes
  • Clarifiers
  • Unique package plants that combine these many of these treatment steps.

Siemens also provides pilot treatment systems and analytical testing to document the efficacy of treatment prior to installation.

GFH Media Removes Arsenic in Arizona Supply

Like many communities in the desert southwest, Phoenix, Arizona’s water supply includes wells with arsenic concentrations exceeding 10 ppb.  Long before the USEPA revised the arsenic rule from 50 parts per billion (ppb) to 10, the City of Phoenix began bench and pilot scale studies

After carefully evaluating all the factors as well as bench-scale and pilot study data, the City selected a granular ferric hydroxide (GFH™) adsorption media from Siemens  to treat water at its well #280 site.   for arsenic removal options.
