Water remediation system
A method of remediating water comprises: reducing the concentration of nutrients in the water and dosing the water with metal ions, e.g. zinc, titanium and/or iron ions. It has been found that through a combination of reducing nutrients present in the water and treating with metal ions, the requirement to treat with high chemical dosages is removed. The dosing agent may be in liquid form and can comprise a metal compound, e.g. a metal oxide, dissolved in an acid carrier. The step of dosing the water with metal ions can be performed by electrolysis. Alternatively, the metal ions can be pumped from a container into the water. The metal ions may be dosed to a concentration of less than 5mg/L. The step of reducing the concentration of nutrients in the water can comprise filtering, wherein the filter can be a biofilter, mechanical sieve filter or an ion exchanger. The water may be dosed with a flocculant to reduce the nutrient concentration. The method can also comprise applying UV light to the water. The pH of the water may be controlled in the range 7.5 to 8.5. A water remediation system is also claimed, e.g. a swimming pool remediation system.
