VaporVeil Project

Pacific AirWell's VaporVeil captures the ambient vapor, humidity, mist, and comprehensive water lost through the mechanical engineering processes inherent to cooling towers found in industrial and commercial applications. Net water loss costs significant amounts of real dollars on a daily basis and the urgent need to conserve water places a greater-than-ever emphasis to find ways to stop wasting water anywhere possible. The VaporVeil addresses the fundamental conundrum to requiring water-based cooling applications for industrial and commercial needs yet reconciling the need to preserve water almost at all costs.

Our team of professionals are looking to capture and reinsert the evaporate to eliminate the need for blow down, saving selective cleaning cycles. The result would be a dramatic reduction in make-up water, blow down wastewater treatment, and flushing away expensive chemicals.

We are performing calculations to come to a comprehensive understanding of the plant’s blow down cycle costs per a given cooling tower or set of towers for that matter. With this discovery in practice, the economic outcome should be very exciting.

Discoveries With Cooling Tower Blow Down

Blow down refers to the mechanism by which cooling towers prevent mineral deposits and scaling within the tower system. The blow down process flushes water through the system and creates a non-potable water solution typically discharged as wastewater.

The evaporate that comes out of the cooling tower is the equivalent of distilled water. Capturing the evaporate and injecting it back into the system will balance the mineralization and require fewer blow down cycles.

Energy (conical cooling towers)

The initial development effort of the VaporVeil product involves capturing the wasted water vapor, mist, and humidity lost from the top of the large-scale towers deployed at energy generation plants. The Lodi Energy Center represents the catalyst for development of a proper solution with millions of dollars in water costs over-expended annually due to a lack of solution to prevent water loss through the conventional cooling tower process. Likely the easiest application basis for a solution, the VaporVeil will apply to the top of the cone design, the focal point for loss within the tower design.

Non-conical or waterfall cooling towers represents the other conventional and, frankly most commonly deployed cooling tower solution globally. Instead of concentrating vaporized water into a system to induce a phase change into reusable water, waterfall towers allow ambient air to create a temperature gradient as water cascades down basically open-air fins in a commonly square-shaped structure. As the water literally falls through the metal fins of the tower the ambient air cools the water temperature into a reasonable range by which traditional cooling equipment can normalize the water temperature. The sheer amount of surface area required to cool the water ambiently reflects a massive challenge to net water loss as nothing inherent to any cooling tower design can prevent water loss while preserving the basic function of the tower.
