PhosBox Lagoon Phosphorus Removal

Triplepoint’s PhosBox Lagoon Phosphorus Removal System Helps Municipalities Cost-Effectively Meet New Phosphorus Effluent Standards

Triplepoint’s PhosBox™ is a low maintenance, tertiary lagoon phosphorus removal system designed to achieve effluent phosphorus limits as low as 0.07 mg/L. As wastewater flows into the PhosBox, it is inoculated with coagulant/flocculant that binds to the phosphorus; the combined mixture is then filtered out by a proprietary cloth media. The clean water is then discharged and the reject water is automatically backwashed and sent to a storage lagoon.

Financially Feasible

The PhosBox Lagoon Phosphorus Removal System is a highly efficient tertiary filter that can be installed between the final lagoon and the discharge/disinfection point. Given its small footprint and low equipment requirements, capital costs are kept to a minimum. Moreover, the filter operation and periodic backwash cycles are completely automated, so no hand-holding is needed. When maintenance is required, the low cost filter media can be replaced in minutes with zero downtime.

Simple Operation

lagoon phosphorusLagoons are simple to operate—they are low maintenance, low hassle, and offer lots of flexibility—making them the perfect wastewater treatment solution for small communities. We designed the PhosBox with precisely this in mind: Wastewater hydraulically flows through the system, sensors continuously monitor phosphorus levels and control coagulant addition, automated backwash cycles clean the filter media, and system alerts tell you when media needs to be replaced based on an increase in backpressure through the filter. All of these features are designed to make the job of operating a PhosBox Lagoon Phosphorus Removal System as simple as an aerated lagoon.

Proven & Predictable

The PhosBox filtration technology has been independently tested and is Title DHS 22 Approved by the State of California. The proprietary cloth filter media has been proven to be capable of solids capture to 10 micron. This, coupled with decades of treatment performance, with hundreds of filter installations in the field, ensure that each PhosBox Lagoon Phosphorus Removal System will reliably and consistently achieve your phosphorus removal requirements.

The Benefits of the PhosBox Lagoon Phosphorus Removal System are:

  • Removes phosphorus down to as low as 0.07 mg/L
  • Small footprint; integrates into existing infrastructure
  • Minimized capital costs
  • Automated coagulant addition and backwash cycles
  • Easy maintenance with no downtime
