The assessment of Struvite recovered from waste water by Terra Eco-Systems and used to produce a general purpose garden fertiliser

Rainbow, A., Rainbow Wilson Associates, UK


Struvite (magnesium ammonium phosphate) has been recovered by controlled precipitation from digested sludge
dewatering liquors using a pilot reactor at Slough Wastewater Treatment Works.
In addition to significant reduction in maintenance costs and other operational problems, this yielded Struvite of high
enough quality to potentially replace the synthetic Struvite used for many years as a slow-release fertiliser in
horticulture and landscaping.

Recovered Struvite was blended with other fertiliser materials and pelletised to produce an easy-to-use general
purpose garden fertiliser.

Laboratory analysis showed that the product was of good quality.
Growing trials demonstrated that the product matched the performance of equivalent proprietary fertilisers over a
range of popular garden plants.
