Principle Mode of action Result Possible disadvantages
Sedimentation Mechanical sedimentation of contaminants Lower turbidity, Less solid contents Time requirement = Volumes for sedimentation process
Skimmer overflow Removal of floating contaminants with fats and oil Less floating layers Loss of water due to overflow
Sand filtration Retaining particulates, as well as substances in part Lower turbidity, Less solid contents It is necessary to clean the sand bed
Multi-layer filter Multiple layers different filter mediums Depending on filter material, cleaning up to micron band, backflushing can be done Frequent backflushing, cleaning expenses
Trickle filter Filter medium do not stay in water instead are continuous Rinsed by water Biological cleaning Cyclical process, power consumption
Sieving Mechanical retention of contaminants Lower solid contents Cleaning, maintenance
Cyclone cleaning The heavy particles are routed out by the centrifugal force generated in the rotating water Lower turbidity, Lower solid contents Requires primary pressure, power consumption
Activated carbon Adsorption Removing non-polar water substances, such as mineral oil and organic compounds Maintenance, depending on dirt
Diaphragm filtration, Micro filtration Mechanical retaining of contaminants up to bacteria size Clear water , Bacteria free Maintenance, costs
Diaphragm filtration, Ultra filtration No longer turbid, Virus-free Keine Trübung mehr, Virenfrei Cleaning, costs, higher pressure = energy consumption
Biological treatment Decomposition of contamination load under oxygen consumption Reduction of COD value = good storage quality Time required = Volume, Oxygen requirement,

Breakdown with certain cleaning agents

Flotation Decomposition through gas pocket Lower COD content – good storage quantity Blower supply, Foam discharge = technical expenditure
Katadyn procedure Bactericide through metal ions Reduction of bacteria and virus over a longer period Dosage


Chlorine Bactericide through chlorine Reduction of bacteria and virus over a longer period Dosage, Cost
UV radiation UV Light Reduction of bacteria and viruses Maintenance, Power consumption, Re-eutrophication
Advanced-Oxidation Process Bacteria and viruses are inactivated with the help of active oxygen Reduction of bacteria and viruses Dosage, Cost
