Wastewater Treatment: Preliminary and Primary DVD

Water comes in many forms: groundwater, surface water, drinking water, wastewater, stormwater, or dual use and reuse. Some forms may need greater treatment than others, depending on where it is discharged or how it is used.

This informative DVD provides a general wastewater overview that also discusses preliminary and primary treatment, and how solids are removed in order to protect downstream equipment and lessen the treatment burden on more costly secondary treatment. Understand that no two treatment plants are identical and, although there are variations among treatment technologies and plant designs, the science remains the same. 30 mins.
