Phosphate analyzer PO4
Testomat 2000® Phosphate
Phosphates are mainly found in fertilizers and detergents. They are released into the groundwater by agricultural fertilizers in the soil or by domestic wastewater with phosphate detergents. In industrial plants, orthophosphates (PO4) are directly fed into the processing water to prevent corrosion in their piping systems.
A high concentration of phosphates and nitrates in the groundwater results in an excessive quantity of nutrients in rivers and lakes. This is the main reason for increased algae growth, resulting in a decrease of oxygen concentration in the water and a sustained disturbance of the ecological balance. In order to prevent this environmental hazard, policies for the concentration of phosphates and nitrates in water have been established.
Phosphates in Sewage Treatment Plants
In wastewater treatment plants, phosphate concentration must be measured in order to ensure effective wastewater treatment. Phosphates are removed by either chemical precipitation or biological elimination from wastewater.
By feeding in dissolved iron salts (ferrous chloride), most of the phosphorus from wastewater is precipitated and deposited along with the contaminants from the primary settlement tank to the bottom of the basin. Increasingly important in wastewater treatment plants is the phosphate recovery from wastewater and sludge, since phosphorus is an important and finite raw material.
The Right Tool for Measuring Phosphate Concentration
In all industrial processes, the measurement and controlling of the phosphate concentration is essential and must be carried out either manually or automatically.
To facilitate this need, we have developed our online measuring instrument, the TESTOMAT 2000® PO4, which continuously measures the amount of orthophosphate in aqueous solutions. The areas of applications include:
- Process water monitoring
- Production water purification
- Wastewater treatment (Wastewater treatment plants, biogas plants)
- Online environmental analyses
Your advantages through online monitoring of a cooling circuit in an industrial process
- Decreased need to add fresh water
- Lower wastewater treatment costs
- Longer use of process water
- Compliance with environmental regulations
Your advantages through online monitoring of phosphate elimination in a waste water treatment plant
- Continuous controlling of critical concentration of phosphate and other parameters resulting in the exact adjustment of the use of precipitants
- Lower operating costs through decreased use of precipitants
- Less sludge
- Reduced impact on the environment
