Moving carbon bed for wastewater.
A moving carbon bed that leaves little sludge.

Sewage or factory wastewater needs cleaning with very little sludge left over. Air and wastewater keep carbon granules moving in a tank.

Problem and fix

The problem this solves.

  1. 01
    The problem

    Sewage or factory wastewater needs cleaning with very little sludge left over.

    How it is fixed

    Air and wastewater keep carbon granules moving in a tank. The pollution breaks down on the carbon as the water passes.

How it works

Step by step.

  1. 1

    React

    Air and wastewater keep carbon granules moving.

  2. 2

    Break down

    Pollution breaks down on the carbon surface.

  3. 3

    Separate

    Clean water leaves the top, carbon stays in the tank.

Key features

Why it works well.

About INR 8 per 1,000 litres. Built up to 15 lakh litres a day.

  • No secondary pollutionNothing harmful is added to the air or ground.
  • Little sludgeSaves disposal cost.
  • Water for reuseTreated water can be recycled.
  • Proven in many industriesRunning in India and abroad.

Questions

Frequently asked questions.

Is this technology proven?

Yes. It is at ready level 9 of 9, which means: already in use. About INR 8 per 1,000 litres. Built up to 15 lakh litres a day.

What does it cost to run?

About about INR 8 per 1,000 litres. The exact figure depends on your water and the size of the plant. We confirm it after testing a sample.

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.

Factory wastewater that fails COD, smells or makes too much sludge

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 9Carbon bed for very strong, toxic wastewaterWastewater from pesticide, dye or chemical plants is so strong it kills the bacteria in the ETP.Ready: level 7 of 9Enzyme filter to remove foam and detergentTreated wastewater still foams because detergent is left in it.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.
