Determination of Phosphate and Phosphate Phosphorus in Wastewater: Analysis Methods

Why Test for Phosphate/Phosphate Phosphorus in Wastewater?

What is Phosphate and Phosphate Phosphorus?

Phosphate is the chemical compound form of the element phosphorus and is usually found as the PO43- ion. Phosphate types found in wastewater are as follows:

1. Organic Phosphates: Phosphorus compounds derived from organic matter. Degraded by biological processes.
2. Orthophosphates (Reactive Phosphorus): The form of phosphate dissolved in water and directly measurable in analyses.
3. Polyphosphates: Complex chain form of phosphate. Usually found in detergents.

Phosphate phosphorus is the part of the phosphate compound present in water as the phosphorus element and is denoted by P. Phosphate and phosphorus levels in wastewater are measured specifically to understand eutrophication (nutrient enrichment) problems.

Causes of Phosphorus Presence in Wastewater

• Fertilization in agricultural areas,
• Detergents,
• Coatings and varnishes,
• Animal waste,
• Other uses.

Increasing the amount of phosphorus in water can cause disruptions in the aquatic ecosystem. It causes a negative increase in algae. For this reason, wastewater disposal processes should be planned appropriately. One of the many chemical analyzes performed in wastewater is “Determination of Phosphate / Phosphate Phosphorus”.

Why Determination of Phosphate in Wastewater?

1. Water Quality Assessment: Phosphate can cause excessive growth of algae in water resources, reducing oxygen levels and threatening aquatic ecosystems.

2. Identifying Pollution Sources: Industrial plants, agricultural fields and domestic wastes are the main sources of phosphate loading. Phosphate determination helps to identify these pollution sources.

3. Compliance with Environmental Regulations: Determination of phosphate levels is a legal obligation under water pollution control. In Turkey, the Water Pollution Control Regulation sets phosphate discharge limits.

4. Monitoring Treatment Efficiency: Phosphate determination is essential to evaluate the efficiency of wastewater treatment plants and optimize phosphorus removal processes.

Effects of Phosphate on Water Quality

1. Eutrophication and Ecosystem Degradation: High phosphate levels lead to algal blooms in lakes and rivers, resulting in reduced oxygen levels. This leads to fish kills and ecosystem imbalances.

2. Human Health Impacts: While phosphate is not known to pose a direct health risk, toxins from algal blooms can threaten drinking water supplies.

3. Treatment Costs: Phosphate pollution increases operating costs by making phosphorus removal processes more complex in wastewater treatment plants.
