About T-FLOC

Water pollutants viz., colloidal, suspended and dissolved cannot be removed by DAF/DGF or by settling. A physical-chemical pre-treatment such as Coagulation or Flocculation is required.

A varying combination of residence times and uncontrolled G-values is a major factor contributing to a disturbed Floc growth. Floc structure, shape and size will differ widely, impeding subsequent separation by DAF/DGF or settling. To compensate for these poor characteristics, the retention time in conventional type flocculators is three to five times longer than those indicated by the jar test.


T-FlocTM is a combination of pipe flocculators and plate flocculators, which are both based on the principle of the “tube-plug flow reactor”.


PIPE Flocculator

The pipe flocculator consists of a calculated length of pipe which is expanded in diameter along its length in order to facilitate the slower ortho-kinetic floc building up. The pipe is divided into certain lengths that are connected by 180° elbows. The result is a “coiled” pipe flocculator that can be suspended on a steel support frame. The flocculator pipe length and diameters can be exactly determined on the basis of jar test results.

Chemicals can be injected into the flocculator precisely at those points where they are most effective. The energy required for the flocculation process is not derived from stirring devices but by well-defined factors such as fluid velocity and pipe friction under plug flow conditions.

Plate Flocculator

The plate flocculator consists of a number of vertical corrugated plates arranged in two or more compartments. The water flows between the plates from compartment to compartment in an alternately upward and downward direction. The first flocculator compartment is the smallest one with each successive compartment being larger, resulting in tapered velocity flocculation.

By raising or lowering the adjustable plates a corrugation phase shift can be affected. The phase shift causes a higher flow resistance between the plates, thus creating increased G-values. The advantage of the plate flocculator is that G-values can be adjusted so that the flocculation process can be optimised to the maximum possible extent. The plate flocculators are mainly used in combination with our plate settlers in process or drinking water plants.


Where to use T-FLOC

T-FLOC coiled pipe flocculators and plate flocculators are ideally suited for a variety of applications where chemicals are mixed with waste streams to facilitate coagulation ad flocculation prior to below separation processes
