The variety of traditional treatment of non-organic industrial waste is very wide, so the purification approach is almost always to be studied on a case-by-case basis.
What all treatments have in common is that energy consumption, especially electricity, is very high, because these are subjected to numerous energy-intensive treatments, among which the main ones are:
- neutralization of ph;
- the separation of the precipitated salts;
- crystallization;
- the drying of the crystals;
- the separation of super-saturated crystals and suspended solids or those deriving from the chemical reaction of purification processes, often carried out with large centrifuges;
- the reaction with chemicals that lead to new less dangerous compounds and lower the costs of final disposal, when they do not allow a complete recovery of the wastewater;
- the recovery of industrial solvents, with the use of redistillation columns, from which however, in addition to the cleaned solvent, from the top, the residual substances come out, usually from the bottom, which must be conveniently disposed of.
Both in the pH neutralization plant units and in those of specific reactions with chemicals, the EMPOWERING DEVICE is capable to avoid large tanks and make the chemical process continuous and fluid, due to making possible to add the neutralizer online.
Without the tanks that must be stirred continuously and for a long time in order not to be stratified and inhomogeneous, the pumps for sending to the neutralization or reaction reactor are also eliminated, as well as the pumps for relaunching the finished product, allowing considerable energy savings and compactness of the plant.
The visual impact of the plant profile is thus drastically reduced, hiding from the eyes of the neighboring inhabitants who will therefore tend to complain less about the existence of the plant itself.
Knowing the characteristics of an incoming wastewater contained in a silos, even horizontal, through a PLC that can be controlled remotely according to the dictates of Industry 4.0, a set of solenoid valves and pumps will lead it through one, two, three or subsequent passages inside the cavitators and special filters designed to eliminate certain aspects of the wastewater to be treated and then add or not chemicals, ozone or whatever else is needed before being shipped to a storage silos of the treated where the wastewater, now processed and inertized, will then be ready to be disposed of.
On the basis of the “families” of origin of the wastewater, specific recipes are created in order to automate the process as much as possible.
