No magic
Cleanit® EC is a groundbreaking water treatment
technology based on electrocoagulation. It uses
uniquely engineered electrodes capable of removing
multiple contaminants from water and wastewater.
These contaminants include multiple heavy metals,
organics, fluoride, arsenic, radioactive isotopes and
even pathogens. The functional units of the electrodes
are highly porous iron particles combined with several
proprietary functional components.
100% green, simple and cost-efficient
Cleanit® EC efficiently separates and removes
contaminants from water. No hazardous byproducts are
generated during the process and no chemical additives
are required. The technology can be applied to a wide
variety of water and wastewater treatment.
Double efficiency, half the cost
If you already use electrocoagulation for wastewater
treatment, we can easily double your process efficiency
while cutting the cost in half. How? You only need
to replace your current electrodes with Cleanit® EC
electrodes and follow the recommended operation. If you
are new to electrocoagulation, we will gladly help you set
up a test unit completely free of charge.
Power of Powder®
Cleanit® EC is developed and patented by Höganäs AB, a
world leader in iron powder established in 1797. We have
more than 1,400 customers in 65 countries and offer over
1,500 products from 14 production centers around the world.
We are driven by innovation. By utilizing the endless
opportunities of our metal powders, we want to improve
resource efficiency and lead a wave of change for the
better. That is what we call Power of Powder®.
Imagine an effective, low-cost, low- energy and low-maintenance process to treat industrial wastewater. Impossible? Not if you let nature do its magic.

Cleanit® EC is an innovative and 100% green electrocoagulation technology. Developed by Höganäs, it completely revolutionizes water and wastewater treatment. Cleanit® EC efficiently removes multiple contaminants such as heavy metals, organics, fluoride, arsenic, radioactive isotopes, pathogens, etc. from water and wastewater, while lowering energy consumption and operating costs.
A green revolution in water purification
Electrocoagulation – the basics
Electrocoagulation is a simple and effective method of
removing various heavy metals, metalloids, organic
substances, ammonia, nitrates, phosphates, etc. from
contaminated water. The process is performed by
applying an electric current across metal electrodes that
are submerged in water. When the electricity passes
through the electrodes, metal ions are released from the
sacrificial anode and combine with hydroxide ions
produced at the cathode. This results in the formation of
polymeric metal hydroxides, which are excellent
coagulants. These coagulants trap and remove
contaminants present in the water. Basic concept of
electrocoagulation is schematically presented in Figure 1.
Unique electrode design
Generally, iron and aluminum are the electrodes of choice as
they form effective coagulants. What makes Cleanit® EC
unique is the design of the electrodes. They are
fabricated using proprietary powder metal technology
and additives, which can be customized to target a
specific or broad range of contaminants in water.
Because of the unique characteristics of these metal

powders, the Cleanit® EC electrodes have very high
surface area to volume ratio. As a result, ionization
efficiency is higher, making the electro-coagulation
process fast and energy-efficient.
An added benefit is that the design of the electrodes is
fully flexible and their composition and shape can be
customized depending on the need of treatment (as
shown in Figure 2).

Chromium removal from wastewater
Hexavalent chromium contaminated wastewater obtained from Brazil
was used for the study. Table 1 briefly summarizes the wastewater
characteristics. Current density of 100 Amp/m2 was applied to the
electrodes. Figure 3 shows the results of the study. After the treatment,
hexavalent chromium was reduced to non-detect and trivalent chromium
was less than 0.01 ppm in the treated water.
