EW Units

Because every water drop counts.

Cleanliness AND disinfection on smooth surfaces rough surfaces !

EW Units produce electrochemically-activated water (EW) for cleaning and disinfection and are used where hygiene and cleanliness are paramount. The use of electrochemically-activated water is therefore suitable for many different industries – ultimately where high hygienic standards have to be met.

Disinfection of surfaces, floors and equipment in the food industry

Washing and disinfection
of fruits
and vegetables

Cleaning and disinfection
of stables
in agriculture

Are EW Units suitable for other areas of application?

From standardised plug-and-play systems to custom solutions

Our EW Units take care of the industrial production of electrochemically-activated water (EW). We distinguish between systems tailored to customer requirements and pro aqua EW Units. Tailored systems are planned and developed in close cooperation with the customer and the customers themselves build the system. pro aqua supplies the components, from the BDD cells to the control system. However, many of our customers request a plug-and-play system and therefore opt for a pro aqua EW Units.

Did you know?

Electrochemically-activated water is now also and mostly used for preventive protection of plants against plant diseases such as mildew or botrytis.
Electrochemically-activated water can be used for a wide variety of applications. We are happy to advise you depending on your needs and requirements.

Plug and Play

Our standard EW Units can be taken into operation right away

Tailored systems

EW Units can also be tailored to customer requirements

Highly effective

Our units produce EW of up to 3,000 ppm
and more

2-in-1 solution

EW: Cleaning and disinfection in
a single step

Standardised and tested

Comly EN 1276, EN 13967, EN 14476 standards as well as Biocides Regulation (528/2012)

Complete system:
pro aQUa EW-Anlage


The systems consist of:

  • Water softening system (optional)
  • Salt water tank
  • EW tank
  • Electrolysis cell(s) with boron-doped
    diamond electrodes
  • Control cabinet


The system’s size is determined on the basis of the following parameters:

  • Litres of electrochemically-activated water
    per unit of time
  • Desired oxidant content


The following prerequisites must be met on the side of the customer in order to be able to put the system into operation immediately:

  • Space for the system
  • Water and electricity connection
  • Salt for the salt water tank

Electrochemically-activated water:
A reliable all-rounder

Electrochemically-activated water can be used in a wide variety of different areas, as they differ greatly depending on the composition of the salt water and the concentration of oxidant produced. In principle, the Electrochemically-activated water produced with EW Units complies with the EU Biocidal Products Regulation (BPR) No. 528/2012 and among others, the following standards:

  • EN 1276 Chemical disinfectants and antiseptics
    (bactericidal activity of chemical disinfectants and antiseptics used in food, industrial, domestic and institutional areas).
  • EN 13697 Chemical disinfectants and antiseptics
    (bactericidal and/or fungicidal activity of chemical disinfectants and antiseptics in food, industrial, domestic and institutional areas)
  • EN 14476 Chemical disinfectants and antiseptics
    (virucidal activity in the medical area)

Did you know?

Generally, pro aqua’s EW Units are designed to produce electrolysed water with a concentration of 3,000 mg/l. However, some pro aqua customers have produced electrolysed water in excess of 10,000 mg/l using its BDD Cells.
We will gladly advise you on the right system for you.
