FERTILIZER AND AGRICULTURAL CHEMICALS INDUSTRY WASTEWATER

Special treatment solutions for fertilizer and agricultural chemicals industry wastewater - nitrogen and phosphorus removal

Fertilizer and agricultural chemicals industry wastewater is characterized by high nitrogen, phosphorus, potassium content and organic matter. Wastewater from fertilizer production facilities requires special treatment processes due to high salt concentration, pH variability and nutrient content. As PİLSAN CONSTRUCTION, we are experts in the effective treatment of fertilizer and agricultural chemicals industry wastewater through a combination of physicochemical and biological treatment.

This wastewater contains; high nitrogen (NH4-N: 100-2000 mg/L), phosphorus (PO4-P: 50-500 mg/L), potassium, salt concentration, wide pH range (pH 2-11), high organic load (BOD: 500-5000 mg/L, COD: 1000-10000 mg/L) and suspended solids.

In Turkey, the Water Pollution Control Regulation (SKKY) and local discharge regulations determine standards and limits for discharge and reuse standards. PİLSAN CONSTRUCTION designs, installs and commissions processes verified by laboratory and pilot studies as turnkey.

For effective treatment of fertilizer and agricultural chemicals industry wastewater, a combination of pre-treatment, physicochemical treatment, biological treatment and advanced treatment is required. Especially nitrogen and phosphorus removal is of critical importance.
