Water treatment 

Oxidation agents, free radical sources and anti-slime agents

Hydrogen peroxide and peracetic acid are environmentally benign chemicals and ideally suitable for the treatment of water in different applications


Waste water treatment with Hydrogen Peroxide & Peracetic acid

Hydrogen peroxide is known to be a strong oxidizing agent, which is used in the pre-oxidation for algae control, precipitation of iron and manganese and for the oxidation of many kinds of dissolved substances, both organic and inorganic.

Furthermore, in biologically active wastewater, hydrogen peroxide will readily decompose to water and oxygen. The release of oxygen can assist in biological oxygen demand (BOD) reduction by allowing the aerobic bacteria to function more efficiently. 

This mechanism is especially important in cases where an oxygen deficiency exists due to high biological oxygen demand / chemical oxygen demand (COD) / Total organic carbon (TOC) loadings and / or insufficient aeration. 

In order to protect waters from microbiological contaminations, peracetic acid can be used as a biocide for the reduction of germs in the purified wastewater of municipal and industrial sewage plants.

Waste water treatment with AOP 

In the Advanced Oxidation Process (AOP) hydrogen peroxide is activated by additional components, such as iron salts (Fenton`s reagent), ozone or ultraviolet light. The AOP technology is one of the most commonly applied approaches for waste water treatment. It is successfully used for the degradation of recalcitrant pollutants in various refinery effluents and waste water especially from chemical or pharmaceutical facilities.
The high efficiency of this process is based on the oxidation power of highly reactive hydroxyl radicals, which are formed by the activation of hydrogen peroxide.

Treatment of recycling water

Water recycling is one of the most suitable methods for saving drinking water and reducing wastewater. In many applications, it is possible to recycle the process or rinsing water instead of removal. Therefore, this approach has an enormous beneficial impact on environment.
On the other hand, the increasing amount of pollutants in the recycled water can be a big draw back for users. Especially the presence of biodegradable organic compounds can result in the formation and proliferate of microorganisms and after a while in a visible and smellable decline of the water quality.

Good examples are car wash facilities in which the majority of the washing water is recycled. 
Bad odors resulting from the metabolic processes of microorganisms can be avoided by continuously dosage of small amounts of germ reducing disinfectants e.g. peracetic acid into the recycle water. In case of an acute smell occurrence, it is also possible to carry out a shock dosage of peracetic acid. Thus, the application of peracetic acid helps to offset the drawback of using recycle water and therefore has a direct benefit for the environment.
