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.
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.
