Removal of phosphorus with Liquiline Control

Phosphorus removal from wastewater with Liquiline Control

Safely comply with limit values, optimize phosphate precipitation, and reduce sludge volumes

Many wastewater treatment plants use chemical phosphate precipitation to remove phosphorus from wastewater. However, phosphate loads can fluctuate, making optimal precipitant dosing difficult. If the dosage is too low, the strict phosphorus limits will not be met. In contrast, overdosing means a higher volume of sludge and thus higher disposal costs - in addition to wasting the costly precipitant. Furthermore, the salinity in the biology increases, leading to corrosion in the plant.

  • Save up to 30% of phosphate precipitant

    Optimize phosphate precipitant dosage and unlock a significant potential for savings! The dosage is at an optimum level if your plant reliably adheres to the limit value but does not use more precipitant than required. How do you optimize phosphate precipitation? By using the Liquiline Control system. It doses the precipitant automatically in accordance with the actual load and your individual phosphorus limit value. The result is reliable and resource-saving phosphorus removal from wastewater.

The automation of the phosphate removal ensures a low phosphorus concentration in your wastewater treatment plant's effluent during both peak- and low-load phases.

Liquiline Control works with iron-based, aluminum-based and mixed precipitants. You can change the precipitant at any time, e.g. if you want to use a different chemical in summer than in winter.

Precipitant continues to be added until the target value you have configured for phosphate is reached and the limit value for phosphorus is reliably adhered to.

Phosphorus removal with Liquiline Control prevents overdosing of precipitant, thereby averting an increase in the salinity of the biology leading to corrosion and an increase in sludge volumes.

How we can help

Liquiline Control is an automation solution that uses continuous flow rate and phosphate measurement to control your precipitant dosing pumps. It can quickly adjust precipitant dosing in the case of changing phosphorus loads or flow rates. This ensures efficient removal of phosphorus from wastewater, which means you use less phosphate precipitant and therefore reduce costs. In addition, optimized precipitant dosing prevents salting of the biology and high volumes of sludge.

  • Full compliance with your prescribed discharge values for phosphorus - even with dynamic influents and high load peaks

  • Optimized phosphate precipitant consumption based on the actual load

  • Control of three dosing pumps at the same time

  • You can use iron-based, aluminum-based as well as mixed phosphate precipitants for your chemical phosphorus removal

  • The process is completely under your control, as you can switch to manual operation at any time
