WASTEWATER TREATMENT
Wastewater treatment plants are part of an essential process for sustainable water management and environmental preservation. These processes make it possible to convert wastewater, which has been used in human activities such as domestic, industrial or agricultural use, into clean water to release it into the environment or to reuse it for other purposes.
The water is collected with the sewer until it reaches the wastewater treatment plants (WWTP) which, depending on their capacity, condition the volume and composition of the industrial wastewater they can take on.
This combination of liquids with waste usually has a pH between 6.7 and 7.5 and is composed of suspended, sedimentable and dissolved solids, organic matter, organic nitrogen, ammonium, nitrites and nitrates, as well as organic and inorganic phosphorus.
Sized solutions specially designed for each project.
Accurate forecasts for correct coordination.
Products subject to strict quality controls.
Detailed budgets with precision and rigour.
The purification process makes it possible to reduce and even eliminate the existing pollutants in the water, meeting the growing demand for water and maintaining the recovery and reuse criteria essential for a society that respects and is aware of natural resources.
One of the most common designs consists of a skimmer or degreaser process, followed by primary sedimentation where a tank decants the sediments that have not been previously retained and that in certain cases can be supplemented with chemicals. Then we find the secondary treatment where a biological tank, bioreactor or digester, using microorganisms, accelerates the natural process of elimination of organic matter. Finally we find secondary sedimentation where we observe the characteristic cylindrical tanks of waste water treatment plants where water and biomass have just been separated.
Our heat exchangers are present in the heat treatment and in the chemical transformations of these processes, as well as in the mud and sludge line that thickens, stabilizes and dehydrates them, facilitating their handling and end disposal.
Heat exchangers for the wastewater treatment plants
Flat tubes heat exchanger
Flat and finned tube exchanger, with a high thermal exchange coefficient can be immersed in liquids or cool/heat oily gases such as in processing plants.
Pillow heat recovery unit
Pillow plate heat exchanger is an innovative equipment ideal for media with an extreme rate of contamination and sedimentation (oily, sticky, dusty, abrasive or sedimented fluids).
Double tube heat exchanger
Double tube heat exchanger or concentric tube heat exchanger allows the recovery of surplus heat in highly demanding processes such as in wastewater treatment plants.
