Description

At a record price of £1.4M for One, 39” long Koi Carp you must question what technologies they use in aquaculture to keep the water fresh and healthy. Evolution Aqua a leading supplier in the aquatics industry have teamed up with WCSEE to transfer technology into the wastewater treatment industry. 

United Utilities immediately saw the advantage of taking a well tried and tested technology from another industry and applying it to ‘P’ removal. 

Keep ‘P’ simple – the objectives:
•    Deliver to site, up and running in 1 day 
•    Back wash frequency every 1-2 weeks 
•    Air scour is used to clean the media so minimal waste returned to head of works or sludge storage  
•    20-minute backwash cycle  
•    No chemical dosing for cleaning 
•    Very low power usage, virtually zero when gravity fed. 
•    Operator input during backwash 10-15 minutes 
•    ‘P’ removal significantly better than 0.25mg/l  
•    ‘Fe’ removal & lt;2mg/l
