How is slurry obtained from waste water treatment?

Purification of water entails removing the polluting components in order to get water in adequate conditions for consumption (purification) or, in the case of wastewater, to bring it into compliance with current dumping standards. Slurries governed by specific legislation are produced during this process, which takes place in wastewater treatment plants. At the same time, these slurries can be processed, allowing them to be reused in agricultural activities, as fertiliser, or for composting.

Its use is governed by a directive that is becoming increasingly stringent. Faced with the prospect of tougher regulations, the industry is looking for alternatives that are compatible with current usage, or that would allow this by-product to remain financially viable. However, the slurry from wastewater treatment can include pathogenic bacteria and parasites that can be dangerous to humans, such as salmonella, E. coli, roundworm, and other parasites. As a result, it's critical to treat the slurry before using it.

What are the recent developments?

There have been researcheswhich show that adding quicklime to these slurries eliminates these bacteria. By establishing a high pH that is hostile to biological activity, adding lime to the slurry lowers smells and pathogen levels. The nitrogen and sulphur fumes generated during the anaerobic breakdown of organic waste are the primary source of slurry aromas. In this very alkaline media, the bacteria involved in the chemical are substantially inhibited or eliminated when lime is added. A similar mechanism is followed by pathogens.

To ensure pathogen eradication and provide adequate residual alkalinity to prevent the pH from going below 11, the pH must be maintained above 12 for a minimum of 2 hours during the quicklime slurry treatment procedure. This gives the stabilised slurry enough time to be stored or regulated. Time, chemical composition, and solids content all influence the amount of lime required to stabilise the slurry. It ranges from 6 to 51 percent in general, with the main slurry requiring the lowest amount of lime and the activated slurry requiring the greatest.

Various methods of slurry treatment

Other slurry treatment methods, such as aerobic and anaerobic digestion, are available, but treating it with lime provides more benefits when reused, as it yields a larger amount of useful product while also providing acid soils with the necessary neutralisation at no additional cost.

The slurry's physical and chemical properties are also affected by the high lime dose. These reactions lower nitrogen, which limits the amount of slurry that can be put to the land; but, they also allow for a greater volume of slurry per unit of area, while also improving the slurry's ability to shed moisture and the nature of secondary fluids.

Is it an alternative for another slurry treatment?

Additional benefit of this system is that it can be used as a back-up for another slurry treatment method because the lime stabilisation system can be started and stopped rapidly. As a result, it can augment existing systems when slurry volume exceeds design limits, as well as substitute incineration when fuel is scarce or when maintenance is required.

Conclusion

The slurry treatment method is not only more cost-efficient than other options, but it is also a safe and effective way to dispose of the slurry, minimising health risks and environmental damage. The slurry may be unloaded perfectly safely once it has been treated and stabilised. It's perfect for agriculture because of its high lime concentration, which makes it an excellent high-quality fertiliser for acidic soils with organic matter and fertilisers.
