The NitrOx® Process Helps Municipalities Meet New Lagoon Ammonia Effluent Standards Within Existing Infrastructure
Triplepoint’s patent-pending NitrOx process was specifically designed to work within your existing infrastructure to cost-effectively remove ammonia from your lagoon effluent. It is a proven, time-tested solution to remove lagoon ammonia that can be installed at 2/3 the cost of existing nitrification options, while also as low maintenance as a lagoon.
The NitrOx Principle of Cold Weather Lagoon Nitrification
Ammonia removal through nitrification will reliably occur with the proper conditions. The purpose of the NitrOx Process is to control and optimize each of these conditions, fostering an ideal habitat for a specific set of bacteria called nitrifiers and super-concentrating them into a small, cost-effective, and highly efficient reactor. In doing so, the NitrOx Reactor guarantees results by:
Maximizing Bacteria Concentration
An increase in nitrifiers yields an increase in ammonia reduction. Nitrifiers grow on substrate or “media,” meaning that in order to increase the quantity of these bacteria, you need to increase the surface area they grow on. The NitrOx Reactor contains millions of small media, producing over 150 square feet of surface area per every cubic foot of volume. This provides for a dense concentration of nitrifiers, and allows the NitrOx Process to be the most effective ammonia treatment solution in the smallest footprint, even at low temperatures.
As the water cools, nitrifiers consume ammonia more slowly. In the coldest winter months, wastewater can be too cold for the nitrifiers to effectively consume ammonia, so the NitrOx Reactor automatically regulates its influent by gently heating the water to 39–42˚F with heat exchangers and geothermal heat, then maintaining this temperature with an insulated cover. Because this temperature increase is minor and only required a few months per year, the NitrOx Reactor operates cost-effectively while promoting rapid ammonia reduction.
Optimizing Mixing & Aerating
Low maintenance coarse bubble diffusers release large bubbles from a full-floor grid, transferring the oxygen nitrifiers need to complete their ammonia digestion. These coarse bubbles also distribute their high-energy mixing throughout the Reactor, agitating the millions of media so the bacteria, the oxygen, and the waste are continuously in contact, creating an ideal environment for rapid ammonia reduction. This same mixing also causes the media to collide with each other, the walls, and the piping sieves, constantly self-cleaning so you don’t have to.
The benefits of the new Triplepoint NitrOx Cold Weather Lagoon Ammonia Removal System are:
- Removes lagoon ammonia down to <0.1 mg/L NH3-N
- Maintains treatment in water temperatures near freezing
- Cost-effectively retrofits your existing lagoons (2/3 the cost of alternatives)
- Low maintenance, simple operation
- Robust design that will last as long as your lagoon
