Flocculation Test Unit

Analysis of a water or waste preparatory
to the design of a treatment sequence often involves coagulation and
flocculation tests, ‘Jar tests’, in the laboratory.

Jar tests are routinely used for the control of plan operations and are performed by treatment plant operators.

The tests serve to indicate the optimum
chemical dosages for removal of turbidity and colour, including such
parameters as pH adjustment, and the supplemental use of activated
carbon. Jar tests, furthermore, yield a wealth of qualitative
information on the rate of agglomeration as a function of energy input
(paddle speed), the settleability of the floc formed, the clarity of the
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
including, for example, the kinetics of reaction and the removal of
trace constituents from aqueous solution.

A bench-mounted framework incorporates
facilities for six tests to be carried out simultaneously. The glass
flocculating vessels stand on a translucent base which is illuminated
from below. Each flocculating vessel incorporates a stirrer paddle
driven by a 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withdrawn for removal and cleaning of the test vessels.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. Paddle speed is accurately maintained by
electronic feedback control. A digital display clearly indicates the
speed which is fully variable. Alternatively, the use of two adjustable
presets allows repetition of pre-selected speeds.

A digital timer can be set to count down from 1 to 99 minutes. After count

down the paddles stop and an alert sounds.
