Electric treatment so tanneries discharge no wastewater.
A tannery that sends out no wastewater.

A tannery must stop sending out any wastewater, but its mixed wastewater is too hard to treat. Each type of wastewater is kept in its own line.

  1. 01
    The problem

    A tannery must stop sending out any wastewater, but its mixed wastewater is too hard to treat.

    How it is fixed

    Each type of wastewater is kept in its own line. An electric treatment cleans each one so the water can be reused and no new pollution is made.

How it works

Step by step.

  1. 1

    Separate

    Each type of wastewater is kept in its own line.

  2. 2

    Treat

    Electric treatment cleans each stream.

  3. 3

    Reuse

    Treated streams go back into the process.

  4. 4

    Recover

    Salts and other inorganics are put to use.

Key features

Why it works well.

Zero wastewater discharge reached.

  • No new pollutionKeeping streams apart avoids mixing problems.
  • Lower costCuts environmental cost by 35 to 40%.
  • Meets zero discharge ordersWater stays inside the unit.

Questions

Frequently asked questions.

Is this technology proven?

Yes. It is at ready level 9 of 9, which means: already in use. Zero wastewater discharge reached.

Can we try it on our own water first?

Yes. We test a sample in our NABL-accredited lab and, where it helps, run a small trial on your site before you invest in a full plant.

Do you supply and install it?

Yes. We design, supply, install and start up the system, train your staff, and our lab checks the treated water.

Ready: level 9 of 9Carbon bed with bacteria for hard wastewaterYour ETP keeps failing the COD test and produces heaps of sludge.Ready: level 9 of 9Moving carbon bed for wastewaterSewage or factory wastewater needs cleaning with very little sludge left over.Ready: level 9 of 9Carbon bed for very strong, toxic wastewaterWastewater from pesticide, dye or chemical plants is so strong it kills the bacteria in the ETP.Problem guideETP Failing the COD TestIf your ETP cannot pass the COD test, adding more chemicals only adds more sludge. Here is what works instead.

THE NEXT STEP

Fix it on
your own site.

Send us a water sample or a test report. We will check it, confirm this method fits and tell you what it costs to run.
