Hungerford & Terry-designed system protects RO membranes at facility in Geneva, Ill.
A new 8-million-gal-per-day Black & Veatch-engineered water treatment center has received the Project of the Year Award for 2009, as well as the Public Works Project Excellence Award, from the Chicago Chapter of the American Public Works Association.
The facility incorporates pretreatment equipment, designed by Hungerford & Terry, upstream of the reverse osmosis (RO) treatment system.
This Hungerford & Terry-designed filter system offers protection to the RO membranes. The filters are sized to treat a flow of 3,576 gpm and remove 3 mg/L of iron and 0.06 mg/L of manganese. Hungerford & Terry’s system includes four 10-ft-diameter by 30-ft-long two-cell horizontal filters and a custom forced draft degasifier to reduce 50 mg/L of carbon dioxide in the RO effluent to 8 mg/L.
The degasifier is housed in the silo portion of the farm building and includes a 12-ft-diameter by 16-ft-tall FRP tower with 905 cu ft of polypropylene tower packing, plus a 16,900 cfm air blower.
“Hungerford & Terry was pleased to provide this specially designed pretreatment equipment in order to ensure effectiveness and efficiency in extending the life of the membranes as well as in saving money in the ongoing treatment process,” said Ken Sayell, Hungerford & Terry’s vice president of sales.
