Compact systems for water treatment
PROCESS
The used components can be classified as follows:
Pre sedimentation tank:
Coarse/fine screens, sieves, preliminary settling tanks for turbidity values > 100 NTU, possible disinfection/sterilization, and aeration.
Preconditioning:
pH regulation, coagulation (destabilization and transport process), and flocculation, equipped with a static mixer and/or mechanical agitators.
Flocculation / Sedimentation:
Combined flocculation and sedimentation area designed as an inclined clarifier with lamella inserts in conjunction with sludge recirculation to reduce chemical consumption.
Filtration:
Depending on the application, the following filtration techniques can be employed based on raw water quality and the hydraulic plant profile:
- Vertical or horizontal pressure filter (WT-AMV-2-B.pdf (110,8 kB)
- Conventional gravity filter (WT-AMV-3_B.pdf (39,7 kB)
- Valveless gravity filter (WT-AMV-4_B.pdf (96,7 kB)
- Continuously backwashable gravity filter (WT-AMV-1_B.pdf (1,1 MB)
Desinfection:
It depends on the degree of organic contamination in the raw water. Disinfection of the treated water and/or in connection with raw water disinfection can be carried out as follows:
- Disinfection of raw water through ozonation or hypochlorite.
- Disinfection of drinking water through chlorination, as well as by UV disinfection or ozonation.
WATER QUALITY & USE
Following the combined treatment steps, the treated water should comply with the drinking water guidelines of the WHO, European, or national drinking water guidelines if the total dissolved solids (TDS) in the raw water do not exceed the value of 1500 mg/l (e.g., WHO limit).
