Phosphorus Removal

Phosphorus is a nutrient that, in excess, can lead to eutrophication, algal blooms, and other water quality issues. Here are some common methods for phosphorus removal in water treatment:

The choice of method depends on the specific characteristics of the water source, the concentration of phosphorus, and the desired level of treatment. Often, a combination of these methods is employed to achieve effective phosphorus removal in water treatment systems. Additionally, it’s important to consider local regulations and environmental impact when implementing phosphorus removal strategies.

Addition of chemicals such as alum (aluminum sulfate), ferric chloride, or lime to precipitate phosphorus as insoluble compounds.

Forms precipitates like aluminum or iron phosphates that can be filtered out.

Process where coagulants are added to water to destabilize colloidal particles, followed by flocculation to form larger flocs that can be removed.

Can effectively remove phosphorus along with other contaminants.

Utilisation of microorganisms like bacteria or algae to naturally remove phosphorus from water through biological processes.

Commonly used in constructed wetlands, biological filters, or activated sludge systems.

Use of adsorbent materials such as activated carbon, iron oxide, or certain clays to capture phosphorus from water through surface binding.

Adsorbents can be regenerated or disposed of after saturation.

Process where ions in water are exchanged with ions attached to a solid ion exchange resin.

Can remove phosphorus ions by replacing them with other ions bound to the resin.

Utilisation of membranes with specific pore sizes to physically separate phosphorus particles from water.

Techniques include microfiltration, ultrafiltration, nanofiltration, or reverse osmosis.

Electrochemical process where electric current is applied to water to generate coagulating agents in situ.

Helps in precipitating phosphorus and other contaminants for removal.

Utilisation of powerful oxidising agents such as ozone, hydrogen peroxide, or UV radiation to degrade phosphorus-containing compounds.

Effective for breaking down organic phosphorus compounds into less harmful forms.

We understand that your biological treatment requirements can be varied and highly dependent on changing legislation within the industry.

Whether treating potable or alternative water sources for process applications. RSE can integrate multiple technologies to provide best practice solutions, including membranes, ion exchange, filtration, chemical dosing, sterilisation and disinfection.
