Plant design

In the field of wastewater and drinking water, the company Acque e Chimici is able to design and take care of the construction of plants.


For the treatment of water, both drinking and wastewater, there are different modes of action. For each problem we work out the specific solution more appropriate . 


For example, with pressure filter systems it is possible to remove trace elements (As, Fe, Si, Mn, V), turbidity, taste, odor and color.
Depending on the characteristics of the water to be treated, different types of filtering mass are selected for an effective and complete elimination of unwanted elements.

A filter equipped with synthetic minerals and/or resins allows for example the removal of arsenic, fluorine or other components.


Arsenic filters 

In the treatment of drinking water it is possible to find arsenic values above the norm, generally due to the intrinsic characteristics of the soil. Our company has already dealt with the design and implementation of filters capable of removing arsenic from water up to suitable values. 

Filters with calcium carbonate or dolomite

For the deacidification of water, an alternative to the use of lime is a calcium carbonate or dolomite filter, which allows an increase in alkalinity and therefore of the buffer effect. The system has obvious advantages, since there are no over or underdosing problems (it self-regulates) and does not require the daily presence of an operator.  


Activated carbon filter

A filter filled with granular activated carbon (GAC) and sand, allows the combined removal of a wide spectrum of substances, such as micropollutants, surfactants, pesticides, suspended solids, etc.

Sand filter

If you have problems with water clarity, a filter with selected sand can remove up to 95% of the turbidity and suspended solids.

Pumps for automatic product dosing 

An automated system for dosing various products used daily, such as flocculants, allows time savings and is even more effective.

Dynamic drum thickener with Archimedean screw​​ - SCRUDRAIN®

Screw thickeners are installed before filter presses, belt presses, centrifuges and drying beds, to obtain a higher concentration of dry matter before dehydration.

Dewatering system with drainage bags - TEKNOBAG-DRAIMAD®

To dehydrate the sludge coming from small and medium capacity plants. The system allows you to dehydrate, pack and store sludge of any kind.
