SevernTrent Services-Apliclor Provides Chlorine Dioxide Disinfection System for Spanish Drinking Water Treatment Plant

Posted: Thursday 2nd September 2010

Severn Trent Services-Apliclor, a leading supplier of water and wastewater treatment solutions, has been selected to design and install a new disinfection system for the Iznájar Drinking Water Treatment Station, which supplies 235,000 residents in the Spanish province of Cordoba.

The system utilizes Aquadiox® chlorine dioxide generators to produce chlorine dioxide on site, providing residual disinfection to prevent bacteria from forming in the distribution network. The new disinfection system, due to be completed by the end of 2010, will improve water disinfection and enable a doubling of water treatment capacity, from 51,840 m³/day to 103,680 m³/day. The contract, which also includes upgrading the existing chlorine gas dosing equipment, is valued at €370,000 (USD $493,000).

According to Rick Bacon, general manager of Severn Trent Services-Apliclor, chlorine dioxide will be used for disinfection as an alternative to the traditional use of chlorine. “Chlorine dioxide reacts less with organic matter present in the distribution network, thus eliminating odours and minimizing the formation of Trihalomethanes, a disinfection by-product that is considered harmful to human health and the environment.”

Severn Trent Services-Apliclor has recently completed a number of major water and wastewater projects in Spain including work in the provinces of Seville, Malaga and Cordoba.
