Purification and sanitary water


'Access to safe water is a fundamental human need and, therefore, a basic huma right. Contaminated water jeopardizes both the physical and social health of all people. It is an affront to human dignity.' Kofi Annan, United Nations (UN) Secretary-General.

Drinking water is a vital resource which is getting increasingly scarcer too. Tomorrow wars could be due to fight for access to drinking water.

WPP equipped with decalcification, ion exchange, activated carbon filter, reverse osmosis, pretreatment, ultraviolets, and ozone. Detail of reverse osmosis membranes, measuring systems, and dosing pumps for treatment.

Compact plants

COMPACT WPP in Salamanca, equipped with dosing pumps for polyelectrolyte and flocculant agents, flocculation coil, additive tanks provided with dosing pumps and agitators, lamellar decanter equipped with claridied water collector in AISI type 316L stainless steel, open sand filters, floating valve with buoy to control water level, sand backwashing circuit and filtered water recovery, automatic solenoid valves, and sludge collection. This WPP has been transported as a whole, and has been placed permanently on concrete poles. When assembled on a SPECIAL TRAILER, it becomes a MOBILE PLANT.

Compact plant equipped with open filters, suitable for 3,000 inhabitants.

Reverse osmosis is a membrane process which allows the removal of up to 99% of both organic and inorganic solids which are dissolved in water.

Compact reverse osmosis plant. Detail of disinfection system.

This reverse osmosis WPP is a complete plant. It is equipped with filters and disinfection, interconnected membranes, high pressure pump, TDS meter, pH meter, water column meters, ion exchange filter (cation or anion exchange resins), and activated carbon filter.



This plant carries out purification process in just one continuous stage, thus resulting in energy saving.

  • Minimum space taken.
  • Modular and versatile.
  • Easy operation and maintenance.

Disinfection system via ultraviolets. Possibility of disinfection by means of ozonation and chlorination.

Concrete slabs with nozzles

Used in sand filters. Several sand layers are placed on a concrete false floor provided with nozzles.

Nozzles are equipped with grilles which retain sand or resins allowing only water through them, diverting water to the bottom of the filters or to other equipment provided with granular beds (sand, demineralization resins, activated carbon, etc.).

Concrete slabs with nozzles assembly. Concrete slabs with nozzles (final result and leak testing).

Decanter by means of flocculation

Decanter by means of flocculation: the floccule traps and thickens suspended matter. As particles join together, they are heavier and precipitate to the bottom.

After flocculation stage, next stage takes place in a decanter.

Homogenizer tank equipped with slow agitator and flocculant agents dosing. Detail of lamellar decanter with conical bottom equipped with scrapers for sludge collection.


POLY-PRO equipment carry out poly preparation from polyelectrolyte powder, by means of an auger filler (volumetric dosing system) equipped with a mechanical variable-frequency drive.

All our models are equipped with mixing chamber, maturation chamber, and storage chamber.

Fully automated preparation by means of an electrical panel equipped with a synoptic.



  • Purification.
  • Wastewater treatment.
  • Sludge dewatering.
  • Industrial processes: paper mills, petrochemical industry…

The two pictures below show polyelectrolyte preparation and dosing equipment, POLY-PRO.


Utility tunnels

Utility tunnels: a practical solution to visual impact on the environment by guiding water, electricity and telecommunications services by means of underground tunnels, also minimizing ecological risks.
