TECHNOLOGIES

The biological treatment is achieved when the dense microbial culture of the activated sludge remains in suspension to the wastewater under aerobic conditions. The organic material is oxidized to CO2 and H2O and forms biological floc that is separated in the settling tanks.

With the Membrane bioreactor treatment (MBR), the biological process is combined with a perm-selective microfiltration or ultrafiltration membrane, specifically a suspended growth bioreactor. Due to the lack of a sedimentation tank, the cost is reduced and the process is ensured.

The MBBR treatment consists of a tank filled with special designed bio-media with high surface area that can provide abundant surface for the biomass to grow and thrive. The biomass will digest the organic waste and convert the soluble material to biomass, which can be removed downstream. With the MBBR treatment, a high degree of efficiency is achieved, the required residence time is reduced and consequently the size of the plant is reduced, with several economic and environmental benefits.

In a sequencing batch reactor the organic matter digests in a single complete mix reactor in which all the steps of the activated sludge process occur for certain periods of time. In areas where there is a limited amount of space, the treatment takes place in a single basin instead of multiple basins, allowing for a smaller footprint.

The physico-chemical treatment of wastewater focuses primarily on the separation of colloidal particles of the inorganic compounds and heavy metals. This is achieved through the addition of specific chemicals combined with mechanical separation methods. Through them, the physical state of the colloids changes, allowing them to remain in an indefinitely stable form and therefore form into particles or flocs with settling properties.

AOPs rely on the use of reactive species that are the strongest oxidants and can be applied in water to oxidize virtually any compound present in the water matrix, often at a diffusion-controlled reaction speed. OH reacts unselectively once formed and contaminants can quickly and efficiently fragmented and converted into small inorganic molecules.

Adsorbent Treatment Technologies can achieve the absorption of the pollutants and the formation of a molecular or atomic film by the accumulation of a gas or liquid solute on the surface of an adsorbent. The absorption is achieved due to the implication of electrostatic forces depending on the properties of the adsorbent and the properties of the waste.

Reverse osmosis (RO) is a purification process that uses a partially permeable membrane to separate ions, unwanted molecules and larger particles from water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential differences of the solvent, a thermodynamic parameter.

The technology is based on the use of ultraviolet radiation through special lamps which after a suitable contact time causes a chemical reaction in the DNA of microorganisms resulting in their death.
