Orange County, Florida is interested in procuring services for the Cleaning Air Quality Control Towers. To date, research within the industry has indicated to the County that Yave Yire Enterprises, Inc. located at 2156 Sunset Terrace Drive, Orlando, FL 32825, is the only vendor that fulfils this requirement.

Minimum requirements are listed below:

OVERVIEW

Orange County Utilities is responsible for maintaining air quality control towers at the Eastern Regional Water Supply Facility 9100 Curry Ford Road Orlando, FL 32825. A contractor will clean all 10 towers at this location twice a year—once in March and once in September.

BACKGROUND

The facility uses a system to clean drinking water by removing hydrogen sulfide gas.

The process is as follows:

• Water is sprayed from the top of special towers while air is blown in from the bottom.

• This process removes hydrogen sulfide from the water and pushes it into the air.

• That air is then cleaned in separate towers (air quality control towers), where water with a high pH (11.0–11.5) is used to pull the hydrogen sulfide out of the air.

• Sodium hydroxide is added to raise the water’s pH, which helps trap the gas.

However, this process causes calcium to build up on plastic media inside the towers. If not cleaned, the buildup can reduce performance or even damage the system. The towers contain thousands of small plastic balls to help with air-water contact and mist eliminators to prevent corrosive mist from escaping.
