Phosphorus Removal

The Situation

Removing phosphorus is crucial for Utilities to meet  the tighter discharge limits of AMP7 and the Water Industry National Environment Programme’s (WINEP) consent levels.

Large treatment plants may be able to achieve the required low P levels, whereas smaller, rural sites will face a greater challenge.  Variable flows,  huge capital investment in additional civil structures (mixing chambers, settlement tanks), high operator levels are just some of the issues faced by Utilities who operate smaller treatment plants.

The Solution

Kolina’s Electrocoagulation technology offers a chemical-free, sustainable, alternative to current options on the market. Our system is a ready to go, containerised unit which can be installed quickly and efficiently into any existing system.

Our treatment method provides a circular economy, not only removing phosphorus from wastewater but the phosphorus-rich floc can then be used as a fertilizer as it’s not contaminated by other chemicals as would happen with chemical dosing systems.

With industry experts on hand, parameters are adjusted and refined.  We offer site specific treatment to ensure optimum results are achieved.

The Results

Requiring very little operator intervention and the benefit of remote monitoring, the Electrocoagulation unit has been working away at Scottish Water’s Wastewater Development Site.

Independent sampling and validation has taken place with results showing a compelling case for the use of Kolina’s Electrocoagulation in the removal of Phosphorus.
