The purification of industrial and municipal wastewater comprises a number of steps such as sieving, filtering, biological treatment and the control of chemical processes. Lutz-Jesco products are thus used for several dosing and control steps during the treatment of process water, including:
Removal of phosphates from the waste water by means of coagulants
Iron or aluminium salts can be used to initiate a precipitation reaction to remove phosphate particles from water. These bind phosphate residues from cleaning agents and detergents so that they can be filtered from the wastewater as sludge. Dosing pumps perform sterling service in this respect. Ingenious dosing technology accessories allow the most diverse wastewater plant requirements and conditions to be mastered.
Application of flocculants
Polyaluminates are added to the wastewater – either in liquid form via Jesco dosing pumps or as a powder via dry material feeders – to increase the size of precipitates and encourage their concentration.
Nutrients for bacteria
Especially in cold months or when the level of water contamination is low, the decomposing and specially bred bacterial strains in the wastewater treatment plant require additional nutrients. These are continuously supplied by dosing pumps, for example in the form of methanol.
