Wastewater is rich in nutrient (mainly Ammonia and Phosphorus). A typical treatment plant will be able to degrade ammonia. But what about Phosphorus? Well, a treatment plant will also degrade phosphorus to a certain degree. In larger municiple treatment plants SBR systems are able to degrade phoshourous
Too much phosphorus (TP) in wastewater discharges can lead to an increase in TP within a river or watercourse. This leads to something called "Eutrophication". Eutrophication is the name given to an increase in nutrient causing an inability for an ecosystem to be able to clean itself. It doesn't need a lot of phosphorus in water to lead to Eutrophication (above 0.1mg/litre). Therefore, if a watercourse has a high level of phosphorus, it is imperative to bring the levels down of all treatment plants discharging into said watercourse.
A treatment plant with chemical dosing can be used to achieve a 90% reduction of phosphorus. Some treatment plants on their own can achieve a 75% reduction, however this is not enough.
Parts of Herefordshire including the River Wry and River Lug are particularly at risk of Eutrophication and therefore require phosphorus removal. Parts of Scotland and wales are also effected.
Yes, the Solido Smart with P removal dosing is capable of 90% reduction in TP.
Whilst installing the right treatment plant is the first step. Due to the sensitive nature of the local ecosystem, it is imperative that such a treatment plant is looked after professionally. Furthermore, the dosing chemical needs to be "topped up" periodically.
