Slurry is a turbid, acidic substance that contains a specific, smelly odor derived from the rotting organic matter that is placed on a large scale in large landfills and landfills every day.
During the decomposition of the materials that go to the trash, together with the water coming from the rain, the slurry originates.
The big problem is that the garbage dumps receive tons of garbage daily, but they do not go through any kind of treatment.
In this way, the slurry penetrates the soil leading a series of pollutants to the earth.
As a result the water table is contaminated and thus occurs to the pollution of rivers and lakes.
The slurry was initially taken to sewage treatment plants.
However, the sewage treatment networks only dilute the slurry in the water, because they did not have the necessary resources and technology for the effective treatment of the same.
Nowadays there are some environmental preservation and recovery technologies that produce some immensely satisfying results.
And it is now possible to transform slurry into pure water, free of any residues from slurry.
Soon after the leachate is collected in landfills, the liquid goes through a series of procedures.
In the initial stage, the slurry flows through a cluster of gratings, which have the function of retaining the largest solid residues.
Subsequently the liquid is taken to a kind of sandbox, whose purpose is to absorb the finer residues, which were not retained by the grids of the first stage.
After passing through the two filtration systems from the previous steps, the liquid is taken to the ponds.
In which the biological decomposition takes place, this process takes in average three days.
The level of oxygen present in the pond is conditioned to ensure the survival of aerobic microbes that have the function of digesting organic material.
At the end of the process, some flakes are generated, which will then be taken to another pond, where the process of decanting the denser solids will be carried out.
That will originate a layer of mud in the deep of the lake.
The liquid resulting from the settling is compatible with the environmental regulations in force.
The sludge from the settling process is cleared with dredge, with approximately 3% solid material.
At the end of the process, the pulp derived from the previous process is taken to a composter.
Which is basically a container used to diffuse organic waste and in this way can be recycled.
The pulp is converted into fertilizer, which can be used in plantations and crops.
Usually slurry producers are landfills and meat producers in general.
Both differ, but each produces an abundant volume of manure.
Usually these companies are constantly in search of solutions to this regrettable picture.
There are now numerous ways of treating slurry.
And there are already some equipment with a cost significantly more in mind, that do not use any chemical or biological treatment during the treatment of manure.
