Sludge Reduction by Ozone

Sludge falls under wastewater management.
It can either be from sewage or from effluent (industrial wastewater).

Our solution is a combination of Methodical Ozone Treatment & Reduced Activated Sludge Treatment, which can reduce sludge production upto net zero.
Not only that, complete de-toxification (high COD/BOD reduction and others), disinfection, de-odorization & de-colorization is achieved.

Ozonation done under a specific process and concentration is a highly effective method in excess sludge reduction because of its advantages such as being compact, clean, and powerful.
In addition to the sludge reduction, it has a positive impact on solubility, dewatering, and filtration.
Ozone decreases the sludge volume and increases its settling rate.
After ozonation, the release of the bonded water in cells or flocs is responsible for decreasing of bonded water and the increase of solid content of dewatered cake.
Moreover, the minimization of sludge volume is helpful to decrease the expense of sludge handling.

In most conventional systems, DAF + Biological treatment + Sedimentation is used.
We are using Ozonation instead of Dissolved Air Flotation (DAF) & reducing the size of Activated Sludge treatment. This is followed by Sedimentation.

For sewage treatment, biological treatment is not required at all, thereby making the process even more simplified : Methodical Ozonation (whereby BOD, COD is reduced below pollution control board norms) --> Sedimentation (using Tube-Deck media) --> Sludge-holding --> Filter Press --> Disposal. Thus the process even reduces the overall capital cost of making an STP by upto 40% and saves space by 50%.
Simultaneously, the Power savings are huge as well.

Our solution offers the following mega advantages :
1. Reduces sludge volume by more than 95%. Increases settling rate of residual sludge.
Even achieves net zero sludge at high concentrations.
2. Increases solubility, helps in de-watering (more solid content in cakes) & enhances filtration.
3. Decreases sludge-handling expenses
4. Lower capital costs, low maintenance, no extra manpower required, less headaches!
5. Reduces energy use at Sludge Treatment Centres :
DAF or other technologies have extremely high energy requirements, whereas Ozonation reduces the energy consumption including the fact that even the retention time is reduced with high ozone dosage. Thus power consumption becomes substantially lower - giving massive savings in the long run, and a superfast Return on Investment.
6. Reducing the carbon impact of the chemicals used at Sludge Treatment Centres :
Multiple chemicals are completely negated when Ozonation is used, as it itself takes care of disinfection and de-toxification of a range of wastewater parameters. Ozone is few hundreds (or thousands) times stronger than multiple chemicals for their respective usages - yet all natural and safe. Ozonation also maintains an alkaline pH under the pollution control board norms.
7. Reducing process emissions at Sludge Treatment Centres
8. Recovering more value from the resources :
Plants fertilized with ozone-treated sludge are characterized by a 50% higher yield of aboveground biomass and over 80% higher content of chlorophyll.

9. Effective sludge recycling :
The Ozone-treated sludge by our process, is easily, safely & most effectively recycled for agricultural use or landfilling.
