ADVANCED TREATMENT (PACKAGE TREATMENT PLANTS)
THE ECO - FRIENDLY OPTION
There are different levels of wastewater treatment. We will explain very briefly below:
PRIMARY TREATMENT of effluent is accomplished with a standard septic tank and treatment field. Involves settling.
SECONDARY TREATMENT is a further treatment of the effluent, and is accomplished using either an Advanced Treatment Plant, or a sand mound field, and provides a very high quality treatment of the effluent that is being returned to the environment. Involves aeration; aerobic treatment.
TERTIARY TREATMENT is even more advanced but is rarely used in residential applications.
Involves disinfection, usually UV.
We measure contaminants/nutrients in the wastewater, and each level effectively lowers the values of each.
ADVANCED TREATMENT PLANTS create secondary-treated effluent, which is a very high quality almost clear liquid. Many times it is difficult to tell with the naked eye the difference between the secondary-treated effluent and normal drinking water.
They are normally placed after your septic tank, and some actually have an integrated septic tank. Eco-sensitive areas or areas with difficult soils may require secondary treated effluent. Homeowners may elect to choose an Advanced Treatment Plant as an eco-responsible decision. Using secondary-treated effluent also reduces the size of the treatment field needed where it is dispersed.
We recommend and design for several Advanced Treatment Plants such as:
