" What is meant by quaternary treatment? "

" In wastewater treatment, quaternary treatment means the fourth treatment stage and refers to processes of advanced wastewater treatment in which micropollutants are eliminated. \r\n The first three stages of wastewater treatment are mechanical treatment (primary treatment), biological treatment (secondary treatment) and phosphorus and\/or nitrogen elimination (tertiary treatment).

Q: " What is meant by tertiary treatment? "

" In wastewater treatment, tertiary treatment means the third treatment stage and refers to processes of advanced wastewater treatment in which a further reduction of nutrients (nitrogen and\/or phosphorus) takes place. \r\n The first two stages of wastewater treatment are mechanical treatment (primary treatment) and biological treatment (secondary treatment).

HUBER solutions for removal of very fine solids and dissolved organic trace substances by means of micro screening, filtration and adsorption.

Solids Retention

HUBER offers proven and reliable solutions for solids retention in the outlet of wastewater treatment plants. In addition to sand and disc filters, a cloth filter is also available for polishing filtration.

Phosphorus Elimination

For flocculation filtration and the elimination of phosphorous, HUBER offers reliable and proven process technology, which ensures that the respective phosphorus limits to be complied with can be safely met.

Biological Activated Filtration

With downstream denitrification in a sand filter during municipal wastewater treatment, nitrate limit values can be reliably met.

HUBER Active Carbon Filter CONTIFLOW® GAK

Elimination of Trace Substances

HUBER offers solutions for the elimination of trace substances and micropollutants from wastewater with granulated activated carbon (GAC) and powdered activated carbon (PAC).

Membrane Activated Process

The membrane activated sludge process is a biological wastewater treatment process that works according to the principle of the activated sludge process, but the secondary sedimentation tank for biomass retention is replaced by membrane filtration unit.

The wastewater treatment process of a conventional municipal sewage treatment plant consists of a mechanical and a subsequent biological treatment stage.

Increasing demands on the quality of the treated wastewater, however, increasingly require additional treatment stages, which are often referred to as third and fourth treatment stages, or collectively as “advanced wastewater treatment”.

The aim of advanced wastewater treatment is the reduction of one or more of the following pollutants: solids, COD, BOD, phosphorus, nitrate, micropollutants and germs.

HUBER is a competent partner for the implementation of different processes for advanced wastewater treatment:

Solids reduction: reduction of suspended solids, COD and BOD before discharge of the wastewater into the receiving water or as a preliminary stage for further treatment
Phosphorus elimination: reduction of phosphorus before discharge of treated wastewater into water bodies
Micropollutant elimination: adsorptive and oxidative removal of micropollutants
Biologically activated filtration: denitrification in sand filters
Membrane activated sludge process: solids-free treated wastewater
