Information on a new radium removal process will be available at the company’s boothHungerford & Terry Inc., at Booth #649 at ACE10, June 20 to 24 in Chicago, has announced a variety of successful projects.

The company was selected by the city of Vineland, N.J., to design and supply equipment to remove radium from four municipal city wells during 2009 and 2010. All of the systems for the four designated wells are identical in specifications and design, and each one includes two 102-ft-diameter exchangers to remove radium.

They were also selected to design and build five 12-ft-diameter by 40-ft-long horizontal multi-cell granulated activated carbon (GAC) filters with a 3,000-cu-ft bed of GAC per filter. This contract is reported to be $2.3 million dollars. The filters will be utilized for pretreatment to a membrane system that will treat 15 million gal of water per day for the residents and businesses in the Santa Fe, N.M., city and county.

The company also announced the introduction of a radium process that removes radium from municipal drinking water supplies at significant cost savings compared with standard ion exchange. Information on the new process will be available at the Hungerford & Terry booth (#649) at ACE10. The radium removal process delivers a significant benefit over ordinary water softener resins: It eliminates the regeneration that produces radioactive brine, thus reducing labor and material costs in the radium removal. With this new process, there is no regeneration step or any waste regenerant.

They also announced the development of two highly efficient nitrate removal systems. The countercurrent removal system is the best choice for most systems because of its extremely efficient design and operation. For smaller systems, where capital costs are of greater concern, the cocurrent nitrate removal system is recommended.

Both the countercurrent and cocurrent systems reduce the nitrate levels in water through anion exchange. The nitrates, alkalinity and sulfates are exchanged for chlorides on strongly basic anion exchange resin.
