Waste water treatment with active oxygens
Oxidation agent and free radical source 

Peroxides and persulfates 

Soil and groundwater remediation, wastewater treatment and air pollution control 

Pollution of soil, water, and air is often due to contaminants such as pesticides, lead, petroleum hydrocarbons and other heavy metals and chemicals, fertilizers, nitrogen dioxide, nitrogen oxide, and sulfur dioxide emissions, leaching or improper disposal of wastes, or fuel and oil deposits. After the negative influences of human actions have become more and more drastic, it became obvious that damaging the environment sooner or later would also have a significant impact on humans themselves.

Peroxides and persulfates contribute to a cleaner environment

Megatrends such as population growth and urbanization are often accompanied by an increasingly drastic impact on the environment. Invariably, the connection between environmental and human health becomes undeniable. We must take measurable, effective action to mitigate the negative influences of human activity. 

When it comes to water treatment, for example, legal regulations stipulate various limit values on pollutants and microbes. Yet the water treatment itself should be part of the solution, not the problem. That is why using the powerful oxidants hydrogen peroxideperacetic acid, and persulfates is optimal for a range of water treatment solutions — from industrial and municipal wastewater treatment, groundwater remediation, recycling water, drinking water treatment, and more. Because once these oxidizing agents destroy non-biological as well as biological pollutants, they themselves break down into harmless substances: mostly just oxygen and water.

 

Environmentally friendly product properties of hydrogen peroxide, peracetic acid and persulfates

The unique chemical properties of hydrogen peroxide as well as its ecological friendliness predestinate this chemical for an extensive use in a variety of environmental applications. There are numerous examples where hydrogen peroxide helps to prevent or reduce negative impacts on the environment. 

Furthermore, hydrogen peroxide is often regarded as a true “green chemical”. In contrast to many other red-ox agents, hydrogen peroxide introduces no additional substances other than water into the reaction system. An excess can easily be decomposed into water and oxygen, not interfering with subsequent reaction steps.

In case of peracetic acid (PAA) the degradation or additionally derived product is acetic acid (AA), which is readily biodegradable in water and not bioaccumulative.

Evonik’s Tonawanda, NY persulfates plant is powered by hydroelectricity generated from the nearby Niagara River. Our KLOZUR® branded products are used to remediate contaminated soil and groundwater sites globally.

Despite its high reactivity, pure hydrogen peroxide and peracetic acid products from Evonik decompose very slowly and, if kept under optimal conditions, can be stored for years. Decomposition can be accelerated by high pH values, high temperatures, UV-irradiation, the presence of transition metal salts and other impurities. Decomposition of hydrogen peroxide and peracetic acid is a quite complex process, which involves formation of various free radicals. In some applications (soil remediation) the decomposition of these oxidizers can be used to enhance performance.
