Wastewater Discharge Pipe

Water used for farming, manufacturing, drinking and other purposes is commonly devalued in quality as a result of harmful contaminants. Therefore, contaminants such as bacteria, nitrates, suspended solids and organic waste must be reduced to an unharmful level if we want to reuse or distribute it back into the environment.

Stormwater running over gardens, paved surfaces and roof tops is also laced with damaging contaminants. It becomes polluted by oil, gasoline spills and chemicals, along with other harmful substances that become embedded throughout the water's journey to rivers, lakes and streams.

Wastewater Treatment Facilities

Environmental engineers are in charge of designing and constructing wastewater treatment facilities. A variety of natural and engineered systems are implemented using biological, chemical, physical and sludge treatment methods.

The features of wastewater treatment systems are determined by the nature of the industrial and municipal wastes that are transferred by sewers and the level of treatment required to improve its quality.

Wastewater FacilitiesWastewater treatment can be divided into categories - primary, secondary and tertiary or advanced. The minimal level of treatment needed is generally secondary treatment, however, a number of industries and cities must install advanced or tertiary processes to remove pollutants that are commonly resistant to conventional treatment.

Conventional Wastewater Treatment

Conventional wastewater treatment includes preliminary processes and primary settling, to extract floatable materials and heavy solids, and secondary biological aeration to flocculate and metabolise dissolved organics. Sludge extracted from these processes is thickened and processed for disposal, generally by landfill or land application.

Primary and Secondary Wastewater Treatment

Primary treatment includes sedimentation and is the process of extracting up to 50% of the suspended solid materials found in raw wastewater. The organic matter that remains following the primary treatment is removed by biological secondary treatment processes to meet sufficient requirements. Secondary treatment is normally carried out using rotating biological contactors, activated-sludge processes or trickling filters.

Tertiary Wastewater Treatment

Tertiary treatment is further treatment which follows the primary and secondary processes. It is implemented when primary and secondary treatment is unable to achieve all that is needed. Phosphorus removal, for example, may be needed for those wastewaters which are discharged to receiving waters that have a high chance of becoming enriched with nutrients.
