Chemical Phosphorus Removal
The chemical precipitation of phosphorus is brought about by the addition of the salts of multivalent metal ions that forms precipitates of sparingly soluble phosphates. Ions of aluminum [Al(III)] and iron [Fe(III)] are commonly used in the chemical phosphorus removal in wastewater. Polymers can also be used in conjunction with alum in order to increase the settling rate in the sedimentation phase or clarification step.

BENEFITS OF Chemical Phosphorus Removal
Chemical phosphorus removal methods can vary greatly depending on your treatment chain. Being in pre-precipitation, co-precipitation or post-precipitation, chemical phosphorus removal needs to be accurately designed to prevent phosphorus loading on your system. There are multiple benefits to chemical phosphorus removal optimization:
- Reduced environmental footprint
- Reduced dosages and costs
- Maximizing wastewater quality
- Maximizing wastewater flow output
- Optimizing capacity of existing equipment
- Helping you meet and exceed discharge limits imposed by your municipality or region
The Aquasan Process for Chemical Phosphorus Removal
Chemical phosphorus removal can be applied on multiple steps of your treatment. A one-size-fits-all treatment is usually not the best solution for these types of treatments, a global understanding of your system and challenges is required. The only way to truly optimize these systems is to have a dedicated account specialist that knows your plant and your challenges. Optimization cannot be done remotely, it needs to be done in collaboration between your team and ours in order to achieve optimal possible results. This true collaboration is what we call the Aquasan process. Aquasan’s Initial assessment, Jar-testing, Jar-testing reporting are always free of charge and Aquasan’s periodic visits are always included while you use our chemistries and services.
1. Initial Assessment
The initial assessment is a crucial step of the Aquasan process as it allows us to get a true understanding of the challenges and opportunities that your wastewater treatment system offers. These are some of the steps that your account specialist will take in order to get a better understanding of your system:
- Survey of facilities and available space
- Survey of equipment
- Survey of the hydraulic flow
- Survey of the existing challenges
- Survey of objectives
By getting all of the information, your Aquasan dedicated technical specialist can start to implement and design a strategy tailored to your specific needs
2. Jar-testing, mobile laboratory and chemistry optimization
Jar-testing is a way to test on a small scale many different chemistry combinations in order to determine which solution could present the best solution. With our mobile Jar-testing kit and laboratory, Aquasan will be directly on-site to perform the jar-testing, ensuring that we get the most representative water from all possible situations from normal operating conditions to sporadic events. Our mobile laboratory will also allow your account specialist to optimize the chemistry to target the phosphorus removal all along your process. Aquasan offers most of its products in many different packaging sizes, therefore upon recommendations from your Aquasan account specialist, the appropriate amount of chemistry will be delivered to you by our logistics team.
3. Plant trial
The plant trial is the next step of the Aquasan process. When a chemistry change is made, it is always vital to do a test on the chain of treatment in order to verify that the expected monetary or performance gains are observed on your equipment. Your Aquasan account specialist will be with you during this plant trial making sure that all transitions are smooth and that no unnecessary downtime is caused by the plant trial. During the plant trial, Aquasan will monitor and log performance for reporting, allowing you to take a decision on qualitative and quantitative data.
4. Periodic visits and Plant optimization
Wastewater systems are not linear, they are a system that can be affected by many different factors. Therefore, Aquasan makes it a point of honor to have periodic visits to all of our customers' plants. Optimizing chemistry through periodic visits allows your Aquasan account specialist to develop a deep knowledge of your wastewater operation. Even if we strive to make your life simple, we know that wastewater can become tricky on some occasions, the knowledge gained by your account specialist will become an invaluable resource for you in challenging times.
Ultimately, the Aquasan process is a way to streamline the optimization and operation processes of your wastewater system. Our goal is to make sure that we are as valuable an asset as our customers are to us.
