Water Treatment


The water treatment plants treat water for its later human consumption. This is the process of common water conversion into drinking water. It normally consists of a stripping of volatile compounds, precipitations of impurities, filtration and disinfection.

Astramatic uses, or combines various technologies, processes and treatments needed for water purification, always according to the standards of quality determined by the authorities of each country.

Providing and process water treatment
Among several of the specialties of the company is the design and provision of process plants, contributing solutions for the use of the water in industry, by means of different technologies


  • Filtration
  • Chemical Meterings
  • Reverse Osmosis
  • Nanofiltration, ultrafiltration and microfiltration
  • Softening
  • Decarbonatation
  • Selective removal of nitrates, boron and metals
  • Degasification
  • Electrodeionization
  • Mixed Beds
  • Chloration


Industrial waste water treatment
Every community generates wastewater that has been previously contaminated by the different uses, for which it has been utilized, from residences, public institutions, industries, etc. There are different types of wastewater, the classification is made with according to its origin, since this origin is what will determine its composition.

Urban Wastewater
Is the discharge generated in urban centres of population as a consequence of their own activities. The supplies generated by this water are:

  • Sewage with human waste
  • Domestic washing water
  • Water from the drainage system of streets and avenues
  • Rain water and leachate

Urban wastewater has certain composition homogeneity and pollution load, as its supplies will be always the same. However, this homogeneity has very wide margins; since the characteristics of each urban landfill will depend on the core population in which it is generated. Parameters such as the number of inhabitants, the existence of industries within the centre, type of industry, etc. have an influx.

Industrial Wastewater

Water coming from any activity or business in which it is used in its production processing, transformation or handling. It is extremely variable in terms of flow and composition. The discharge characteristics are different, not only from one industry to another but also within the same kind of industry.

Sometimes, industries do not release a continuous discharge, but only at certain times of day or ever only at certain times of year depending on the type of production and the manufacturing process. Variations in flow and load throughout the day are also normal. These are more polluted than urban wastewater and this contamination is more difficult to remove.

Its high load together with its enormous variability makes the treatment of industrial wastewater complicated and a specific study for each case is necessary.


Water reusability
Astramatic has a wide range of technologies based on the characteristics of the water to be treated, among them being the following:

  • Safety filtration
  • Ultrafiltration
  • Reverse Osmosis
  • Desinfection

The reuse of wastewater is a resource of unconventional water that has been developed in recent decades. However, in order to proceed to reuse this resource require appropriate technologies and detailed earlier studies. We review the relevant technologies, as well as legislation regarding the reuse of wastewater. Generally, the reuse of wastewater is used for irrigation and urban clean.

Nanofiltration is a process of selective division using pressures of up to 10 bar (145 psi). Ultrafiltration is widely used in the division of milk and whey, and in protein division. It concentrates solids in suspension and solutes of molecular weight greater than 1000. The permeate contains organic solutes of low molecular weight and salts.

Reverse osmosis is a highly effective technique for dehydration treatments, concentration/separation of substances of low molecular weight in solution, or treatment of remains. It has the ability to concentrate solids in suspension or dissolved. The permeate contains a very low dissolved solid concentration. Reverse osmosis is applied generally to sea water desalination.
