Permeation tubes 

KIN-TEK Trace Source™ permeation tubes use a mixture of reagent-grade nitric and sulfuric acids as the analyte source. The sulfuric acid binds the water, reducing water emission to negligible levels. Emission of the sulfuric acid is extremely low compared to that of nitric acid, so the emission is primarily nitric acid. Formation of nitrogen oxides in the vapor is minimized by dynamically blending the emission to form trace concentration mixtures that are then used immediately. Tubes are available for concentrations from low parts per billion to about 10 ppm in
1-L/min dilution flow. KIN-TEK Laboratories Inc. (La Marque, Texas).

Spray nozzle 

The Spray Nozzle trihalomethane (THM) removal system for medium and small tanks is effective at removing all four types of regulated THMs. The system provides tank mixing and THM removal in one. A submersible pump pushes water through the spray nozzles, where THMs are volatilized and removed from the water. Simultaneously, some of the pump flow also is directed through an efficient mixer located near the bottom of the tank. In cold climates, the THM removal function can be switched off while the mixing function continues to prevent ice damage in the tank. It is portable and prepackaged for user or contractor installation, with minimal permanent infrastructure changes. It includes the assembly, tank-mixing system, submersible pump, piping, and tank adapter. SolarBee Inc. (Dickinson, N.D.).
