AGW Antech Gütling - Continuous systems for wastewater treatment


Application fields

Before waste water is discharged into the sewerage system, it must be treated and purified pursuant to statutory provisions and using the latest technology. Continuous systems are proven and tested economical processes and are employed for major waste water flows with low pollutant concentrations.

In general, the continuous system is employed in the following procedure steps:

  • Neutralization
  • Precipitation
  • Flocculation
  • Sludge separation

General process description

The waste water passes through a number of tanks which are equipped with agitators and in which the corresponding reactants are added by metering. The precipitated sludge particles are separated from the waste water with the settling cyclone or compact settling tank developed by Antech-Gütling and dewatered into a dumpable filter cake with filter presses.
The respective treatment process depends on the respective waste water substances and is accordingly determined

Description of system

The incidental waste water is buffered in a storage tank to achieve a homogenization in view of concentration and flow rate. The waste water is raised to the inlet level of the continuous system with a pumping station. Subsequently, it passes through it in gravity flow without any shearing stress. Depending on the available overall height and the nature of the formed sludges, they can be separated from the waste water with a settling cyclone or a compact settling tank. The settled wet sludge is further compacted in a sludge thickener.
In the further course of the process, the sludges are dewatered into a dumpable filter cake with a chamber filter press. In particular cases, a membrane filter press can be employed.
For secondary cleaning, a sand filter and, if required, a selective ion exchanger are employed. The clarified water flows into the sewerage system through final pH control

Advantages

  • Treatment of major waste water flows with low pollutant concentrations
  • Continuous operation mode
  • Relatively small footprint
  • Standard sizes
  • Corrosion-resistant design
  • High degree of automation
  • Minimum operating efforts
  • Sludge separation and pre-thickening in one system
