Technology

Kolina’s EC technology offers a greener alternative to chemical dosing for removal of phosphorus; it generates coagulant ferric ion species through an electrochemical reaction in the EC cells between passed current and sacrificial electrodes.

The generated coagulant ions have a utilisation efficiency of close to 100%, whilst dosed chemicals such as ferric sulphate and ferric chloride have active coagulant ion mass fraction hence utilisation efficiencies of between 28% and 34%.

The choice of anodes can also be tailored to use mild steel, aluminium, magnesium, and/or mixed metals oxide as sacrificial electrodes which can benefit sites with discharge limit/consent for metals, thus offering an added versatility to the end user.
