SSR20240407B01 Flocculation test unit Educational Equipment

Description

The equipment allows for the well-known ‘jar tests’ to be conducted on water samples requiring treatment to determine the correct coagulant dosage on a laboratory scale as a prelude to full-scale plant operation.

Flocculation and coagulation are preliminary tests carried out prior to designing a water or waste water treatment plant. Jar tests are routinely used for the control of plant operations and they serve to indicate the optimum chemical dosages for removal of turbidity and colour, necessary pH adjustments and the supplemental use of activated carbon.

Jar tests yield a wealth of evaluation of agglomeration rate as a function of energy input (paddle speed), settleability of the floc formed and the clarity of supernatant water (which might be related to the subsequent length of filter run).

Coagulation and flocculation tests may be used, in conjunction with other tests, to study basic processes, eg the kinetics of reaction, filterability index and the removal of trace constituents from aqueous solutions.

Incorporates facilities for six tests to be carried out simultaneously.

Each flocculating vessel incorporates a stirrer paddle driven by an independent variable-speed drive. The paddle assemblies are easily withdrawn for removal and cleaning of the test vessels. The paddle shafts are made of stainless steel to resist corrosion.
