ZM8137B Flocculation Test Unit Vocational Training Equipment Hydrodynamics
Experiment Apparatus
Description
It demonstrates the removal of dissolved substances by
precipitation and flocculation with subsequent sedimentation.First,
raw water is produced in a tank to contain dissolved metal (e.g.
iron). A pump transports the raw water to the precipitation tank.
Here the precipitant is added (e.g. caustic soda). Due to the
reaction of the dissolved metal ions with the precipitant,
insoluble metal hydroxides form (solids). From here the water flows
into a flocculation tank divided into three chambers.
The purpose of flocculation is to improve the sedimentation
properties of the solids. By adding a coagulant in the first
chamber the repulsive forces between the solid particles are
cancelled out. The solid particles aggregate into flocs
(coagulation). To generate larger flocs, a flocculant is then added
(flocculation). In the third chamber low flow velocities are
present to prevent any turbulence. Turbulence would impede the
formation of flocs. The now well sedimentable flocs are then
separated from the treated water in a lamella separator. The
treated water and the sedimented flocs (sludge) are collected in
two tanks.
Flow rate, temperature and the pH value are measured. In addition,
the pH value in the precipitation tank can be controlled. For
measuring the conductivity an external meter is available. Samples
can be taken at all relevant points. The cover of the tank is
transparent for the inspection of the treated water.Analysis
technology is required to analyse the experiments. The choice of
analysis technology depends on the substances used. Trivalent
metallic salts are usually well suited as coagulants. Common
flocculants are organic polymers.
