Say goodbye to BOD, ammonia, or nitrates.

SAY HELLO TO THE BIOPORTS MBBR.

Combining the proven BioPorts moving bed biofilm reactor with Nexom’s unmatched nitrification expertise and patented processes means facilities with footprint restrictions can beat their ammonia (or BOD or nitrate) limits too

Find Out if Bioports is Right for your Installation

MBBR and IFAS technology promises major nitrification, minor footprint.

Whether you’re building a greenfield treatment plant or retrofitting a facility, this is great news. BioPorts has proven itself in a wide range of applications, from standalone MBBR systems to converting activated sludge plants into IFAS facilities to lagoon-based systems requiring ammonia reduction. 

Nexom’s acquisition of the BioPorts MBBR puts its established strengths in the hands of the company that knows BOD and removal and nitrification—especially nitrification in the most extreme conditions—better than anyone.

FULL AMMONIA REMOVAL IN less than 1°C WATER.

Lagoons love winter when they've got a SAGR.
Find Out Why

The Nexom SAGR® is designed to follow wastewater treatment lagoons or other secondary treatment processes to provide full nitrification in cold water temperatures. The SAGR reliably achieves effluent Total Ammonia-Nitrogen levels below <1 mg/L in water that’s <1°C/34°F

Beat phosphorus limits as low as 0.02 mg/L

For every regulator's action imposing ultra-low phosphorus limits, Blue PRO is the equal and appropriate reaction.
Blue Pro Reactive Filtration

You didn’t choose your limits, but you can choose to beat them. When ultra-low levels of phosphorus or metals can do a lot of damage, wastewater treatment plants can become targets of regulatory pressure to meet low levels of phosphorus and metals limits. Beat those limits with Blue PRO. 

REMOVING SOLIDS OR PHOSPHORUS

requires a full-time solution, so when you need to remove solids or phosphorus turn to the
Infini-D Zero-Downtime Cloth Disk Filter

The infini-D™ Zero-Downtime Cloth Disk Filter is ideal for solids and phosphorus removal. It provides optimal filtration and allows individual disks to to be removed, inspected and maintained while other disks continue filtering. Tank de-watering is not required, and the system stays online while being maintained.

Imagine your lagoon as a HIGH-PERFORMANCE TREATMENT FACILITY.

With optAER, it can be.
optAer Fine-Bubble Lagoon Aeration

Nexom’s optAER® family of lagoon upgrades is created to give you the tools you need to meet BOD and TSS effluent quality requirements and turn a lagoon into a low-O&M, high-performance treatment facility, including fine-bubble aeration, floating laterals, self-tensioning headers, HDPE ball covers, and much more.

You can try squeezing the last 0.1% out of your SOTE, but low-hanging fruit can COME OFF THE BELT.

Optimize your plant with 30% less BOD and 60% less TSS thanks to
Ecobelt Rotating Belt Filtration

Thanks to EcoBELT’s size, performance, and cost, primary treatment is finally scalable. With a small footprint, a relatively low capital cost, and proprietary advantages that make it the most operator-friendly rotating belt filter to date, now primary treatment can be upgraded.

With great nitrifying power comes TOTAL NUTRIENT REMOVABILITY.

Beat Total Nitrogen and Nitrate limits with
BlueNite Biological Denitrification

The simple, flexible, biological way to beat nitrate limits. Built upon a continuous-upflow sand filter platform, Blue Nite creates the optimal conditions required for denitrifying bacteria to thrive. And where denitrifiers take hold, nitrates don’t last long.
