5 Parameter values used in water quality analysis

Parameter is a measure of wastewater value and wastewater quality from various sources. It is important for wastewater treatment systems before releasing it into the environment.

1. pH  

pH is the acidity/alkalinity of water. The pH range is from 0 to 14, with 7 being neutral. A pH range below 7 indicates acidity and a pH range above 7 indicates alkalinity. The general industrial pH value is below 4.5, which means it is very acidic and highly corrosive. (The pH value of drinking water should be between 6.8 and 7.3)

2. BOD (Biochemical Oxygen Demand)

The amount of Biochemical Oxygen Demand used in the biochemical process to decompose organic matter in wastewater is measured in mg/L. A high BOD value indicates a high level of dirt or organic matter in the water.

3. COD  (Chemical Oxygen Demand)

The amount of Chemical Oxygen Demand used in the chemical process to decompose organic matter is measured in mg/L. Normally, COD is always than BOD. Therefore, COD is an important that indicates the dirtiness of wastewater.

4. DO ( Dissolved Oxygen ) 

Dissolved Oxygen in water is a parameter used to control the quality of source water. The standard for good quality water is generally a DO value of around 5-8 ppm, while wastewater DO values should be less than 3 ppm.

5. TDS ( Total Dissolved Solid )

The total amount of Total Dissolved Solid, inorganic and organic substances in water, including metals, minerals, salts, and ions dissolved in water, is an overall indicator of the presence of chemical contaminants in drinking water and the water quality. (Standard drinking water values are set at no more than 500 mg/L (PPM)).

Wastewater is not only a problem that affects the environment, it also has an impact on human health if not properly treated, contaminated wastewater can release toxins and bacteria into water sources.
