Advanced Oxidation Process (AOP)

Advanced Oxidation Process filtration, or AOP as it is known in the water industry, is an exciting, newer technology to drinking water suppliers. It uses the power of ultraviolet light and an added oxidizer in the form of Hydrogen Peroxide, to destroy any contaminants that may be present in the raw water supply. It can remove all VOC contaminants plus other contaminants, such as 1,4 Dioxane, that are not removed through traditional filtering methods like Air Stripping and GAC. Bethpage Water District utilizes AOP at all of our sites except one location, as it is not required at the lone location.  BWD led the industry in 2014 and instituted a full scaled pilot study of this system in 2014 with success at our Park Lane plant. This type of filtration is the future of not just Bethpage's needs but of just about every other supplier on Long Island.  AOP is the only approved method to remove contaminants like 1,4 dioxane.

Air-Stripping

This technology is used by many public water suppliers across Long Island, New York as more sophisticated testing is available and stricter testing requirements are being implemented. This proven state-of-the-art equipment is in place at three of the district's plant sites to remove any traces of volatile organic compounds that may be present in the water that is pumped from the ground long before it enters the public supply system.

Based on the principal of exposing a large surface area of water to air, the process is relatively simple to understand. Water is pumped to the top of a tower and then cascades downward over a large number of packing materials or small round objects that look like ping pong balls. At the same time, filtered air is blown upward through the tower, breaking the water molecules and removing or "stripping" any contaminants in its travels.

GAC Filter

Removal of organic compounds with a granular activated carbon filter is based on the principle of adsorption. The activated carbon's porous composition provides tremendous surface area that acts as an absorption system. The water is purified as it passes through the carbon filters. The used carbon is replaced periodically according to industry standards. GAC filters are similar to air strippers in that they both remove volatile organic contaminants.

Nitrate Removal

The ion exchange process for the removal of nitrates is both simple and effective. It operates in the same manner as a common water softener and easily can remove much more than 90 percent of the nitrates. The process uses a strong base anion exchange resin, which is regenerated with common salt.

Backup Generators

The Bethpage Water District has equipped its plant sites with backup diesel generators to ensure the smooth operation of each facility and to keep the pumps running and the water flowing in the event of a power outage. Whether it's a brief loss of electricity or major blackout like the one caused by Hurricane Irene in late August 2011, the necessary equipment is in place to handle the incident so the water remains available for drinking and fire fighting.
