DECA Clarifier

The ODIS DECA Clarifier is an automatic hydraulic device, specially designed to accelerate reactions through methodical recirculation of the precipitates formed by the flocculent and influent water. The DECA Clarifier operates continuously, to provide required effluent water quality.

The Clarifier consist of three chambers:

  • Flocculation (reaction) chamber is a central conical chamber, where influent water ejected through special nozzle.
  • Intermediate cylinder, to reach a good growth of the flocs.
  • Settling chamber, where a separation between sludge and the effluent water is achieved.

Principles of Operation

The water to be treated, mixed with flocculent, enter the DECA Clarifier through a venturi type on-line flocculator placed in the bottom of internal (reaction) chamber. The up-stream flow of flocculated particles over close to the top to the intermediate cylinder chamber. This way the liquid is forced to flow downward precipitating heavier particles. The sludge deposited in the settling chamber returns to the reaction chamber by induced flow. The resulting sludge “enrichment” allows rapid flocculation and formation of the dense precipitate.
The conical floor of the unit helps the sludge slide toward the ejector for recirculation. Concentrated sludge is collected at the bottom hopper and periodically released to drain.
The effluent flows over the truncated conical collector into the intermediate tank for further treatment.
The DECA Clarifier has no moving parts.
