Trion now offers Ecotec -- a unique water pretreatment system -- with every system we sell because water pretreatment will enhance the humidification system's performance. Many pretreatment systems can also promote dusting. Our patented process removes undesirable minerals from your water, while leaving it in a non-corrosive, non-scaling state even in deionization (DI) or reverse osmosis (RO) or ion exchange water. Ecotec creates equilibrium, which improves system performance and increases the life of the humidification system.

DI and RO can leave water in a corrosive state, requiring the humidifier to use relatively expensive materials to resist this corrosion. Discharging this type of charged water will collect dust and be attracted to an opposite charge, thereby creating a dusting problem. A third widely used approach, ion exchange (or water softening) can also erode the system over the long haul while leaving the water in a charged state that promotes sodium dusting.

Herrmidifier´s Ecotec system offers a safe and stable alternative to conventional pretreatment options. Herrmidifier engineers understand that water is the life blood of any humidification technology. Herrmidifier´s Ecotec system employs a patented process that removes undesirable minerals from your water while leaving it in a non-corrosive state.

Because any minerals or impurities present in the water source will be injected directly into the air stream, Herrmidifier recommends conducting a complete water analysis prior to the design of your humidification system. There are no cookie cutter solutions to water treatment, so your unique humidification system design and source water quality will determine which water pretreatment solution is best for you.

Ecotec has developed a packaged system based on both the specific source water analysis and the humidification application it must perform within. This system must remove adequate mineral content in the water, yet retain just enough minerals to leave water in a less corrosive and non-scaling state (equilibrium).

Herrmidifier's Ecotec System: How it works

Sequence of Pretreatment
Domestic cold water and hot water are mixed through a tempering valve to obtain a temperature of 77°F (25°C). The exact combination of prefiltering is selected based on the application´s specific water analysis. After prefiltering, the water flows to the PWC/NANO filtration system at a minimum of 50 psig.

The first stage of the PWC/NANO Filtration System employs a physical water conditioning process, which is based on the principle of nucleation enhancement under the influence of magnetic resonance. Calcium carbonate forms around the newly created nucleation center in the water and the previously dissolved calcium carbonate precipitates to the new seed center and surrounds the center to form the micron crystal or platelet. The viscosity and surface tension is also decreased.

The second stage employs a crossflow membrane filtration process that removes particles in the 300-1000 molecular weight range (or an approximate weight cut-off of 150-300 Dalton for uncharged organic molecules), rejecting selected salts. Divalent and multivalent anions are preferentially rejected by the membrane. Monovalent ion rejection is dependent upon feed concentration and composition, however. Since monovalent ions pass through the membrane, they do not contribute to osmotic pressure or with the physical water conditioner´s ability to decrease surface tension. The membrane permeate flux is enhanced by the physical water conditioner´s improvement of boron retention and the flow rate, as well as reduction of scale formation at the solid-liquid interface. This synergy enables the Herrmidifier Ecotec system to reduce energy usage and maintenance costs as well as water consumption and sewage charges.

After treatment by the PWC/ NANO, the water, which is at equilibrium (between -.5 and +.5 on the Langelier Index) flows directly to the humidifier or to a non-pressurized storage tank. If the storage tank were used, a level control in the tank would operate the PWC/NANO system. A repressurization pump would then provide 75-85 psig pressure at the pump discharge and 50 psig to the humidification systems.
