Water Treatment

Water Treatment is defined as a physical-chemical and biological process, where the degree of existing pollution is decreased and assessed by means of parameters both physical-chemical (pH, Temperature, Conductivity, Suspended Solids,...) and microbiological (Biochemical Oxygen Demand, Analysis and Colonies Count,...).

Classification

As far as the source of water to be treated is concerned, we can differentiate 3 types of SEWAGE WATERS TREATMENT STATIONS:

- Urban Sewage Treatment Plants

These plants treat sewage water from houses in urban centres. For small and medium populations, we normally use underground compact sewage treatment plants, thus minimizing the visual impact. For big population centres, it would have to be measured according to the existing number of equivalent inhabitants and the peak flow, building then a Sewage Water Treatment Station by means of a civil work.

- Industrial Sewage Treatment Plants

The dumping from a factory or an industry is very different, depending on its activity. For this purpose, it would be neccessary to carry out a complete analysis of the sewage water from such industry and know the minimum values of certain parameters according to the Law and then, once the sewage water has been treated, dump it to the public sewer systems. In the event of industries, the water treatment performed generally is that of Physical-Chemical type.

- Agricultural Sewage Treatment Plants

These plants treat the “manure” obtained from farms and stables, and it’s made of a mixture of feces, orine, and cleansing water for farming facilities.

Treatment Uses

Depending on the final use of treated water, we can also classify it in 2 large groups:

- Controlled dumping

The values of certain parameters foreseen in the Law must be complied before dumping into a river or to the sea, thus protecting both Public Health and Environment.

- Reuse in farming irrigation

Treated water is used for the irrigation of green areas and agricultural fields, thus preventing the possible damages to crops as well as to aquifers in the area.

Whatever the final use of sewage waters, the current tendency is to PURIFY it, in a way more or less intense depending on the purpose or on the area where it is going to be dumped. In the event of its exploitation or if it’s going to be dumped to the sea, the installation of a Treatment Station is essential for built-up urban areas in terms of sanitary guarantees derived from TREATING the Sewage Waters.

In many areas in our country, the dump of non-treated sewage waters into a course or to the sea, represents a serious pollution problem, deriving in the phenomenon of “eutrophication” in reservoirs, swamps, bays and, in general, in all those mass of water with a low hydrodynamic activity.

Therefore, the sollution to the problem of cleaning up any urban or industrial community must pass through an appropriate treatment of the sewage waters, together with an appropriate evacuation system or a convenient reuse.

The determining fact in order to choose a water treatment system, the structural design of the station and the guidelines of the treatment to be performed is the cost of the system, the number of inhabitants, the polluting load, the seasonal variation and the subsequent use of the affluent.

Conclusions

AGUAMED, SOC. COOP. design, manufacture and build your Station for Treating Sewage Waters, whatever its origin or final destination. Our TREATMENT equipment is manufactured with resistant and first quality materials, guaranteeing an optimum process during the whole treatment of sewage waters.

Furthermore, we provide an excellent After Sales Service (Maintentance, Spare Parts,...), guaranteeing solutions before any kind of problem that may arise during installation.

Once we know the source water, the volume of sewage water to be treated (in its absence, the number of inhabitants) and the final use of treated water, AGUAMED, SOC. COOP. can provide you with a quote for your Desalting Plant without obligation.
