Compact systems for water treatment

We offer compact water treatment plants, generally consisting of prefabricated system components or frame-mounted plant groups, as well as primary treatment stages such as raw water collection, coarse and fine screens, or sieves. The treatment process essentially involves chemical conditioning, flocculation, filtration, and disinfection for plant capacities ranging from 20 to 500 m³/h, equivalent to a population of 3,000 to 80,000 people.

Our compact plants are applied in municipal water supply, with particular emphasis on operational safety, ecological aspects, cost-effectiveness, and the long-term maintenance of drinking water quality. Our compact and well-proven basic design (e.g., static mixers, sludge recirculation & flocculation, lamella separators, continuous backwash filters, etc.) allows for the realization of very space-saving plant concepts. Thus, even in limited space conditions, a reliable solution can be provided without compromising on the essential aspects of water treatment.


The raw water normally available from surface water sources is, however, not directly suitable for drinking purposes. The objective of water treatment is to produce safe and potable drinking water. Generally to treat surface water (e.g. river water, lake water and well water) the treatment process consists of Coagulant Dosing, Mixing, Flocculant-Aid Dosing, Flocculation, Sedimentation, Filtration and Disinfection. 

The main goals of AMV package units are removing suspended solids, turbidity and pollution from the available raw water in each area, providing a treated water quality based on WHO, european or national standards. The applied design criteria and the components of a water treatment plant depend on the turbidity and pollution of a known raw water source.

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.


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.


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)


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.


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).
