Siemens Water Technologies will provide two OSEC systems, similar to the one pictured, for the Ballymore Eustace Water Treatment Plant in County Kildare, Ireland. Ballymore is Ireland’s largest WTP, serving approximately 70% of Dublin.
Ballymore is Ireland’s largest WTP, serving approximately 70% of Dublin. The expansion will allow the plant to increase its capacity from 250 Ml/d to 318 Ml/d, with a planned peak capacity of 400 Ml/d.
Through the electrolysis of a brine solution, the OSEC system produces a 0.8% sodium hypochlorite solution, consuming only salt, water and electricity. This solution is stored in a day tank and injected into the distribution system by a metering pump. Fifty-seven liters of 0.8% sodium hypochlorite is equivalent to 0.45 kgs of chlorine gas or 3.79 liters of commercial sodium hypochlorite (12%).
The plant and its engineering contractor, Earth Tech of Dublin, considered onsite hypochlorite generation systems from other manufacturers, but Siemens provided one of the smallest footprints. A comparable competitive system would have required multiple units to produce 1,000 kg/d of chlorine, compared to Siemens’ OSEC systems that will each be capable of producing 1,000 kg/d of chlorine. Both units will operate in tandem producing 24 hours’ worth of chemical during the 8 hour low-tariff energy period, thus saving costs.
