The Singulair TNT (Total Nitrogen Treatment) system from Norweco reduces total nitrogen by more than 68 percent. Certified performance data from NSF International verifies that the average effluent produced by the system contains 7 mg/L nitrate, 12 mg/L total nitrogen, 4 mg/L CBOD5 and 9 mg/L TSS. It offers flow equalization, effluent filtration and low electrical usage. Designed for easy installation, operation and maintenance, the system minimizes effluent nitrogen concentrations, without requiring effluent recirculation or the addition of dangerous chemicals. All treatment is accomplished within the tank. It is a reliable treatment method for nutrient reduction in onsite treatment and disposal systems, and complies with the most stringent regulations. 800/667-9326;
