One industry that is in dire need of rescue from harmful Hydrogen Sulfide (H2S) is the wastewater treatment industry. FreshAWL® solutions virtually eliminate H2S, reduce selenides, remove mercaptans, and are excellent at sludge reduction while being an affordable, safe, and organic replacement for the harsh and expensive chemical methodologies currently in use.

Wastewater — What Is It?

Potable (drinkable) water becomes wastewater after it turns contaminated with natural or synthetic microbiological compounds introduced by human, commercial, or industrial activities along with other natural sources.

Unless properly treated, wastewater can harm public health and the environment. Most communities generate wastewater from residential, commercial, or industrial process sources.

Wastewater Treatment Plants (WWTPs) are very complex in what they do. Some receive millions of gallons of wastewater from toilets, sinks, showers, restaurants, launder-mats, and others every day.

Spoiled and disposed wastewater can really stink! It can stink even more when the accumulated waste begins to decompose at a local community WWTP.

This bacterial decomposition or breakdown of waste gives off foul odors (foul odors are caused when bacteria ingest sulfur, rather than the preferred oxygen, producing a byproduct of Hydrogen sulfide) that are strong enough to permeate an entire community. In some cases these H2S odor levels can reach concentrations strong enough to cause injury or death.

There are many methodologies in use today for controlling these foul odors and there are many considerations that must be taken into consideration such as cost, safety, the environment, asset protection, and how the plant is viewed by its community.

With all that said, we believe and we are able to show that our FreshAWL solutions work the best for wastewater treatment plants for controlling foul odors and eliminating Hydrogen sulfide.

WOW-Air water soluble formula demonstrates its strength in water based environments such as Wastewater Treatment Plants (see San Francisco Airport test results).

WOW-Air can be induced at any point in a WWTP system. It can be metered, poured, misted, or fogged anywhere odor control, H2S removal, or elimination of mercaptans and selenides is necessary.

Here's how FreshAWL works as a sulfur elimination technology for oil or water waste treatment systems:

FreshAWL Z-FOG(Oil Soluble for Fats, Oils, and Gases) and WOW-Air (Water Soluble) products work directly on sulfur, the source of foul odors.

NOTE: Waste disposal companies can rest assured that the FreshAWL™ base molecule has none of the negative effects that other products containing surfactants.

Eliminates Hydrogen sulfide, selenides, and Mercaptans

  1. FreshAWL solutions work quickly and specifically to bind up sulfur;
  2. The beneficial bacteria are freed from the poisoning sulfur when it is bound by FreshAWL;
  3. This reaction has shown a natural increase of O2 which optimizes the bio-chemical balance of treatment systems; and
  4. Simply put, FreshAWL does its job, freeing the bacteria to do theirs. 

WOW-Air works safely, efficiently, and provides a green solution which leads to lower cost.

Prior to WOW-Air, Environmental Health and Safety (EH&S) Managers relied on expensive, corrosive, unstable, and dangerous to handle chemicals like these:

  • Bleach-Chlorine
  • Ferric Chloride
  • Ferrous Chloride
  • Ferrous Sulfate
  • Hydrogen Per. 50% Oxygen
  • Bioxide (Calcium Nitrate)
  • Nitra-zyme
  • Thio-guard
  • Calcium Hydroxide
  • Potassium Permanganate

In addition to the expense associated with the short life span of these chemicals within the system and special OSHA handling requirements, they can also cause corrosive harm to the systems they clean and to the environment.

FreshAWL® WOW-Air™ will make you say WOW!

For effective elimination of H2S, mercaptans, and selenides, your best choice is the powerfully safe organic chemistry of WOW-Air.
