What is water treatment ?
Water is a fragile resource and is essential to the development of mankind. Waste water treatment is a major public health issue in many countries throughout the world. Water treatment is the process that removes contaminants (organic and mineral) from industrial or municipal water. To be injected back in the usable water circuit, it needs to undergo one or more physico-chemical processes that vary according to the final use, whether it has to be drinking water or not. The use of the treated water is either industrial or municipal.
Specificities of the water treatment market
There is more and more wasted water to be treated in the world and it becomes a challenge every day to handle it in short, middle and long term. Water treatment processes run continuously and deal with clear liquids as well as sludge. Equipment operating in this process has to face different rheology, in thin as well as in viscous fluids.
These environments require simple, efficient and economical equipment.
Steps for mixing water treatment
LUMPP® stirrers are designed to work in :

Frequency converter for floccurator
Hasler group provide its monitoring and control module allowing to optimize and control the agitator performances. This helps to extend the product life of the machine and to detect any need for maintenance.
Options :
- PTC Sensor
- Motor + gear box
(specific request) - Adjustable plate
LUMPP® solutions for water treatment
To reach these standards, we offer mixers without sealing and impellers specifically adapted to water treatment.
LUMPP’s team is also able to adapt the equipment to the environment described in your specifications.
Coagulation
The coagulation process consists in adding products to the water to remove all the charges between the particles. Ferric chloride, aluminum sulfate for example. Polymers are also added which will then allow flocculation. During this step, rapid mixing is necessary.
Floculation or Maturation
Flocuation step un waste water treatment plant
Here comes the polymers to allow the particles agglomeration together. We try to create the biggest flocs as possible. Medium to slight agitation is required to promote the formation of these flocs while avoiding shear destruction.
Neutralization
The aim of neutralization is to neutralize the water to allow coagulation or flocculation operations adding lime, soda or sodium carbonate. The water pH must be 7. The Number of Agitation is 4.
Sludges
The coagulation, flocculation and neutralization stages produce a lot of sludge which containing a high proportion of organic products, in a more or less liquid state, which must be treated. The aim is to reduce the volume to limit the quantities to store
