Water Disinfectants and Oxidants

150 years ago, chlorine was first introduced as a water disinfectant. Back then, it was the only choice for treating drinking water. Today, there are many more water disinfectants. This list includes ozone, hydrogen peroxide, chlorine dioxide, potassium monopersulfate (KMPS), UV radiation. Each of these disinfectants has a different strength and suitable for different applications. They are all effective for disinfecting water, and avoid some of the complications associated with the use of chlorine.

Above all, water disinfectants can be used as oxidants. Oxidants remove organic and inorganic components in water by oxidation. A special case is UV radiation that triggers oxidation and disinfection by direct photolysis of molecules.  In addition, one of the strongest oxidants is formed during UV light dissociation of hydrogen peroxide. This reaction produces hydroxyl radicals, the strongest known oxidant in water treatment.

Chlorine Dioxide

Chlorine dioxide is an advanced disinfectant for water and wastewater treatment, as well as for disinfecting swimming pools. Unlike chlorine, chlorine dioxide does NOT produce carcinogenic compounds as a by-product of disinfection. For drinking water, chlorine dioxide is better than regular chlorine. Chlorine dioxide has a long-lasting effect through residual concentration – something that neither ozone nor UV can provide.

Our liquid sets for chlorine dioxide production consist of Hydrochloric Acid 9% and Sodium Chlorite 7.5%. Both components are ANSI60 certified for drinking water. You can purchase these liquid sets from the Osorno Online Store and directly from our company.

PowerOxide™ Disinfectant

The PowerOxide™ chlorine dioxide kit consists of two components used to produce chlorine dioxide. PowerOxide™ is often used when you cannot invest in a chlorine dioxide generator or when you only need to produce singular batches of chlorine dioxide. Both components are ANSI60 certified for drinking water. You can purchase PowerOxide™ disinfectant from the Osorno Online Store.

KMPS

KMPS, potassium monopersulfate, (the K comes from “kalium”, the Latin word for potassium) in its stable form is a triple salt and a highly active oxidant. You can use this chemical for a wide range of applications, such as disinfecting drinking water, disinfecting wastewater lagoons prior to discharge, disinfecting swimming pools, or sanitizing water reservoirs (dugouts) for small communities. You can use potassium monopersulfate with sodium or calcium hypochlorite. KMPS is ANSI60 certified for drinking water. You can purchase KMPS from the Osorno Online Store or directly from our company.

Hydrogen Peroxide

Hydrogen peroxide (perhaps best known for its use as hair bleach) is a slow-acting, but strong disinfectant. The oxidation potential of hydrogen peroxide even exceeds that of potassium permanganate. It is best used to oxidize organic matter in raw water, enabling easy removal through flocculation. You can use hydrogen peroxide with chlorine dioxide (but not with chlorine or hypochlorite). You can purchase Hydrogen Peroxide from the Osorno Online Store in 4 L and 20 L containers.

Sodium Hypochlorite (Liquid Chlorine, Bleach)

The disinfection compound in sodium hypochlorite is hypochlorous acid. This acid forms when chlorine gas dissolves in water.  You cannot isolate hypochlorous acid from sodium hypochlorite because it exists in equilibrium with its precursors. This equilibrium depends on numerous factors. The disinfection efficiency of sodium hypochlorite depends on the water's pH. An acceptable pH for efficient disinfection is 6.8 – 7.5. Hypochlorous acid reacts with organic compounds and forms THMs (trihalomethanes).

In addition, hypochlorous acid reacts with ammonia to form chloramines, which are a weak secondary disinfectant. There are many different types of chloramines. Monochloramines form in a pH range of 7.5 - 9.0. The most acceptable pH for water chloramination is 8.2 – 8.3. You can purchase Sodium Hypochlorite 12% from the Osorno Online Store.

Sodium Bisulfite

Sodium bisulfite (also known as bisulfite bleach or sodium hydrogen sulfite) is a reducing disinfectant.  Sodium bisulfite reduces residual chlorine in chlorinated water. It also reduces residual concentrations of chlorine dioxide and hydrogen peroxide and it can prevent oxidative corrosion. You can purchase our 32% sodium bisulfite solution from the Osorno Online Store.

Ozone

Ozone (O3) is produced when oxygen (O2) is exposed to UV light. It is a powerful oxidant for treating water and air. Because ozone decays quickly, you cannot manufacture and transport ozone like other industrial gases.
