INDUSTRIAL WASTEWATER AND ZLD / 14

Ready: level 6 to 9 of 9Already in useSmall site

Compact unit with filters, UV and ozone.
One compact unit for small-site wastewater.

A small site needs to clean wastewater, rainwater or sewage for reuse on plants. Water is settled and filtered through treated natural filter material, then UV light and ozone kill the germs.

    The problem

    A small site needs to clean wastewater, rainwater or sewage for reuse on plants.

    How it is fixed

    Water is settled and filtered through treated natural filter material, then UV light and ozone kill the germs.

How it works

Step by step.

  1. 1

    Settle

    Solids settle out.

  2. 2

    Filter

    Treated natural filter material removes dissolved pollution.

  3. 3

    Disinfect

    UV light and ozone kill germs.

  4. 4

    Backwash

    Filters are rinsed to last longer.

Questions

Frequently asked questions.

Is this technology proven?

Yes. It is at ready level 6 to 9 of 9, which means: already in use. About 1,000 litres an hour at about 5 paise a litre.

What does it cost to run?

About 3 to 5 paise a litre. 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 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.
