Technologies

There are many technologies today that apply and combine to respond to the water requirements arising from day-to-day activity in the various sectors of the main productive agents of the company.

 

Below we relay the most common technologies:

FILTRATION

Mechanical separation of particles. Primary filtration systems:

 

  • Silex
  • Silex/Anthracite
  • Silex/Anthracite/Garnet
  • Active Carbon
  • Iron Removal
  • Cartridges
  • Bags
  • Rings
  • Netting
  • Hydrocyclone

Membrane technology used for selective removal of suspended matter, particles, large macromolecules, colloidal matter and microorganisms, but which does not remove ions or dissolved material. The diameter of the membrane hole is between 0.1 and 0.001 µm.

 

It has several advantages over conventional filtration: lower chemical consumption, more efficient removal of contaminants, better and greater continuity in the quality of the filtrate, more compact plants and simpler automation.

REVERSE OSMOSIS

System designed for producing water with low salt content, free from viruses and chemical contaminants. Osmosis membranes are used, configuration of which varies according to the nature of the water to be treated.

 

Performing suitable pre-treatment is the most important requirement for making sure a reverse osmosis facility operates well, as well as exploiting and maintaining it correctly.

Treatment to remove ions dissolved in water (Calcium, Magnesium, Sulphates, Biocarbonates, Metals and Nitrates, among others) using resins from ion exchange, which reactivate by using regeneration agents. Types:

 

  • Decalcification
  • Demineralisation
  • Decarbonation
  • Mixed Beds
  • Denitrification
  • Other
ELECTRODEIONISATION (EDI)

Refinement technique to achieve ultra-pure water. It takes place continuously with no consumption of the chemical.

 

Energy consumption is directly proportional to the quantity of salt displaced and water loss is very low, around 5-10%.

 

Resins are regenerated continuously electrochemically through ion-conductive membranes and by applying electricity.

Technology that aims to destroy or deactivate pathogens in water.

The most common methods are:

 

  • Physical Methods: Ultraviolet Radiation.
  • Chemical Methods: Ozone, Hydrogen Peroxide, Chlorine and its derivatives
PILOT PLANTS

This is a processing plant on a reduced scale which is designed, built and operated to establish the technical and economic viability of a physical or chemical process.

 

It is much more flexible than an industrial-scale plant because it enables work to be conducted at a wide range of values which make it possible to establish the optimal operation parameters for the process to subsequently design and build the industrial-scale plant.

Treatment which removes colloidal particles by destabilisation and subsequent formation of floccules. It consists of 2 stages:

 

 

  • Coagulation – flocculation: floccules are formed by adding chemical reagents.
  • Clarification: process that eliminates floccules using systems of Filtration, Flotation or Decanting.
BIOLOGICAL

This is applied mostly for water high in biodegradable organic material (soluble and colloidal), as well as for removing compounds that contain nutrients (Nitrogen and Phosphorus, predominantly).

 

According to the features of the water and organic load to be treated, we have various kinds of treatment:

 

  • MBR
  • SBR
  • Activated Sludge
  • Plug Flow
  • Anaerobic Systems
  • Other

Effective technology to treat liquid industrial waste, which can create a zero-dumping treatment system. It enables waste to be minimised by concentration, which reduces the cost of managing it.

 

The water treated is of such high quality that it can be reused in the industrial process.

 

It is widely used in sectors whose activity has a large impact on the environment, such as iron and steel, chemical, pharmaceutical, paper and leachate industries.
