DPD Test - Pool For Thought

A DPD test is a water test designed to test oxidizer levels such as free chlorine, total chlorine, chlorine dioxide, bromine and ozone. DPD, also known as DPD-1 and known chemically as N,N Diethyl-1,4 Phenylenediamine Sulfate. For a DPD test to be accurate the water pH level needs to be balanced, or the test results can become errored.

How Much Ozone Do I need to Treat Water

The amount of ozone required is mg ozone/mg Fe and mg ozone/mg Mn. Hydrogen Sulfide (H2S) creates an unpleasant odor in water (rotten eggs). In drinking water applications the H2S is often removed to make the water more palatable. The theoretical amount of ozone required to remove H2S is 3 mg ozone/mg H2S, but in practice and excess ...

The Role of Ozone in Water Bottling | WQP

2003-09-19· This ozone gas stream is brought into contact with the water to be treated in a device called an ozone contactor. In the ozone contactor, the ozone is dissolved in the water and the undissolved ozone in the off-gas is discharged through an ozone decomposer and released at rooftop levels.
