Are you listening
to the water?
It has a lot to say.
At LaNova we speak the acoustic language of water. Our advanced AI machine learning takes what your process is telling us and makes it actionable — the right chemistry, the right dose, the right day.
01Listen
Acoustic feedback reads the process as it runs.
02Learn
AI machine learning finds the pattern in the signal.

Cost-effective water treatment
Lanthanide chemistry,
done seriously.
LaNova removes phosphorus with reduced coagulant volumes and less sludge — a fractional resource for plants that need process improvement and compliance without a full-time chemist on staff.
Pro-rare-earth chemistry
Lanthanide blends developed in-house for North American water — not borrowed from drinking-water playbooks. Chemistry that targets phosphorus, not everything around it.
Why LaNovaExcellent phosphorus removal
Lanthanides bind phosphate selectively into a dense crystal, achieving effluent below 0.07 mg/L at significantly lower dose rates than ferric or aluminum salts.
See the chemistryAcoustic feedback
Our field techs listen to the process itself — acoustic feedback shows how the chemistry is actually behaving in your water, so the phosphorus removal program gets tuned to your plant instead of guessed at from a bench test.
How we evaluatePolymer residual monitoring
We measure polyelectrolyte (polymer) residual left in your effluent, so dosing never carries over far enough to blind MBR membranes or foul RO units in tertiary treatment.
Membrane safetyLess sludge volume
Up to 60% less chemical sludge than ferric chloride, aluminum chloride, or polymer coagulants — dewatering drier cake and shrinking every truckload to the landfill.
Cut your sludgeProven results
Rare-earth chloride chemistry deployed across North American plants from 0.02 MGD to 45 MGD — field evidence, not just jar tests.
Case studiesPowerful benefits
Greater water clarity, faster coagulation, improved sludge dewatering, better digester performance — with no staining or discoloration of facility structures.
Plant impactHow it works
Traditional coagulants are non-specific and demand massive doses. Lanthanides have a strong, selective attraction for phosphorus — less coagulant, less sludge, less cost.
Jar test trainingLaNova measurement technology
Particle size should not change the answer
A solids number is only useful if it means the same thing from one day to the next. LaNova's acoustic backscatter measurement holds its calibration across the particle sizes that actually occur in wastewater — from 20 nm colloids to 250 µm grit.

01
Scattered, not reflected
The transducer emits a pulse at a wavelength longer than most particles present, so the wave scatters off the solids instead of reflecting off a surface. The intensity and time-evolution of the returning echo are the measurement.
02
Blind to color and turbidity
Because the signal is acoustic, liquid color, turbidity, temperature and the speed of sound in the medium have little effect on the reading. There is no optical window to foul.
03
Fine particles are the hard part
Optical backscatter response varies by a factor of 10 to 100 across the 1 to 100 µm range, and conventional ultrasound at 3 to 10 MHz only stays size-independent above roughly 100 µm. That gap is where most real suspended solids actually sit.
04
Validated where other methods fail
From 20 nm to 250 µm — the range where optical and standard acoustic sensors both lose the signal — our measurement holds within a factor of 5 of the reference concentration at 20 µm.

Dewatering intelligence
You cannot control what you never measure
Centrate and filtrate quality is the fastest honest read on whether your dewatering is working. LaNova monitors it, interprets it, and turns it into the setpoint decisions your operators actually make.
What your dewatering is losing
Solids in the centrate or filtrate are solids your centrifuge, press or DAF did not capture. We measure continuously across 0 to 2,000 mg/L, so the trend shows while there is still time to act on it.
Polymer you paid for and did not use
Residual polymer in the centrate is the clearest read on over-dosing. Centrate commonly runs 0 to 2,000 µg/L, and dewatering is most economic in the 200 to 400 µg/L band. We watch where your dose curve flattens.
A setpoint, not a lab report
Live measurement feeds the decision — sludge feed rate, dewatering parameters and polymer concentration, adjusted as the sludge changes.
Measurement that stays in service
High solids and heavy polymer loads foul measuring equipment. LaNova owns the maintenance schedule, calibration and cleaning so the numbers stay trustworthy.

Custom.
LaNova means "the new" — and like our name, our chemistry is unique, specialized, and custom. It's a tool we bring to solve your problem, not a product we're here to sell.
Where standalone rare earths are expensive and collapse in variable water, our patented lanthanide blends perform across that variability at a fraction of the dose — non-hazardous, engineered to your water. The right chemistry, deployed as a service.

Inventors: Scott Frazier & Jon Khachaturian · App. No. 16/924,751
Treatment of wastewater generated from animal processing (poultry, beef, pork) using rare earth density modifiers — lanthanum, cerium, and praseodymium salts — to modify the protein phase density and enhance lipid fat phase separation from protein solids.

Municipal WWTP · Tertiary Phosphorus Removal
South Fork Coeur d'Alene River Sewer District · Page WWTP · Osburn, Idaho
The South Fork Sewer District needed to optimize phosphorus and metals removal at the Page WWTP to meet a stringent NPDES permit limit of 0.15 mg/L total phosphorus. Esvelt Environmental Engineering conducted a comparative jar-testing program evaluating three coagulants — 48% aluminum sulfate, 38% sodium aluminate, and a 45% cerium and lanthanum chloride rare earth solution — across a target pH range of 7.0 to 9.0 S.U. Alum and sodium aluminate were tested first; neither could achieve the 0.15 mg/L target under the permitted pH conditions.
