The OxiMax MC Series
The OxiMax MC Series is designed to produce Sodium Hypochlorite (NaOCl) from seawater or water with salinities > 4 g/l.
Description
The OxiMax MC Series Seawater Electrochlorination System produces high-quality sodium hypochlorite directly from seawater, delivering safe, cost-effective and environmentally responsible biofouling control for industrial cooling water and seawater intake systems.
The OxiMax MC Series is designed to produce Sodium Hypochlorite (NaOCl) from seawater or water with salinities > 4 g/l. These heavy duty, high performance cells use Thermomoulded PVC casings and bipolar electrode arrangements for optimum energy efficiency, safety and NaOCl production.
Typically, a side stream of seawater is taken from the discharge of the seawater pumps directly to the Electrochlorination Plant. This seawater is strained to 400 micron and passed into the electrolyser cells. DC power is applied to the seawater inside the cells which results in the production of Hypochlorite. The OxiMax MC Series uses staged Hydrogen removal through the electrolyser train via multiple Hydroclones, resulting in superior Hypochlorite production and energy savings. The Hydrogen flows to the Hypochlorite storage / degassing tanks where the Hydrogen is diluted to < 4% (typically < 1%) and safely purged to atmosphere. The Hypochlorite is then dosed into the seawater intake lines to prevent marine growth and biofouling of the mechanical equipment such as the cooling water pumps, the bar screens, drum screens and condensers as well as the cooling water pipelines of the power station.
Each OxiMax MC Series system is controlled by a high quality PLC with a colour HMI, for ease of control.
