TB221018S07 Flocculation Equipment Teaching Equipment Fluid Mechanics Experiment Equipment

INTRODUCTION

Drinking water or wastewaters, in different volumes, contain suspended material, solids that can be settled at rest or dispersed solids that do not settle easily. A substantial part of those solids that do not settle may be colloids. In natural conditions, they cause cloudiness, color, smell, taste and solids.

Water purification processes involve the collection of colloidal material, which is indispensable in the wastewater purification and treatment processes.

The coagulation and flocculation operations destabilize the colloids and make them settle. This is usually obtained with the addition of chemical agents and the application of mixing energy.

The Flocculation Test Unit allows to study the coagulation and flocculation operations and to analyze the main parameters that determine the colloids removal operation.

GENERAL DESCRIPTION

The Flocculation Test Unit shows the removal of dissolved substances by coagulation and flocculation.

It has six beakers where water to be tested is poured. Each one has one adjustable speed paddle stirrer.

The unit is illuminated from the rear side to allow a clear visualization of the supernatant particles.

The instrumentation of the unit allows to determine temperature, pH and total dissolved solids (TDS) to set, thus, the optimum conditions for flocculation
