Physical separation and process protection
Filtration and ultrafiltration of water in the Canary Islands and Africa
We design systems to control solids, turbidity, colloids and microbiological load, protect facilities and stabilise water quality prior to each process.
A barrier for each fraction
Good filtering starts with knowing what needs to be retained
There is no universal filter. We combine stages depending on the size and nature of the solids, water variation, flow rate and the sensitivity of the process to be protected.
Media leak
Deep retention to reduce solids and turbidity using selected beds and appropriate service velocities.
- Sand, anthracite and specific media
- Pressurised or open filters
- Manual or automatic backwash
Safety filtration
Final protection by means of cartridges, screens or self-cleaning filters before pumps, membranes, heat exchangers and processes.
- Filter cartridges and bags
- Automatic meshes and discs
- Differential pressure control
Ultrafiltration
Membrane barrier for finer, more stable separation from turbidity, colloids and microorganisms.
- Compact modules
- Backwash and chemical cleaning
- Flow and transmembrane pressure control
Deep filtration
Turbidity and solids control without oversweeping the installation
We size the filter media, the effective surface area and the face velocity to maintain the flow rate with a controlled pressure drop. Backwash automation adapts to consumption, water availability and intake variation.
- Well water, galleries, mains network or surface water catchments.
- Irrigation protection, processes, UV and reverse osmosis.
- Simple, parallel or redundant configurations.
- Specific media for iron, manganese or other parameters when the analysis justifies it.
Industrial equipment
Pressurised filters, batteries and selected media for each flow rate
Industrial filtration is not defined solely by microns. The construction of the equipment, the effective surface area, the valve arrangement, the backwashing regime and the ability to maintain service while a unit is being serviced also matter.
Individual equipment and batteries
For moderate flow rates, compact units can be used. In higher-demand installations, we design parallel banks, alternating configurations, or standby reserves.
- One or more filtering water bottles
- Continuous service and redundancy
- Modular expansion in stages
Vessels, valves and control
We select vessels in composite material, coated steel or stainless steel depending on the water and the application, with manual or automated operation.
- Automatic valves or manifolds
- Electric or pneumatic actuators
- Backwash by time, volume or head loss
Filter beds and media
Layer combination is determined by the contaminant, the filtration rate and the quality objective, not by a fixed recipe.
- Flint and anthracite for particles and turbidity
- Activated carbon for chlorine and organic matter
- Zeolites and specific media where appropriate
Membrane separation
Ultrafiltration for a more stable quality
Ultrafiltration works as a low-pressure physical barrier. It allows turbidity, colloids and the microbiological load to be consistently reduced, even when the feed water exhibits variations that complicate conventional filtration.
- Advanced protection for reverse osmosis and other sensitive processes.
- Production of water for drinking, reuse or industrial use.
- Automatic sequences for filtration, backwashing and cleaning.
- Membrane flow design, recovery and transmembrane pressure.
Selection criterion
From the visible solid to the dissolved pollutant
The technology changes according to the fraction to be controlled. This separation avoids offering ultrafiltration where a simple filter is enough and avoids promising that a UF membrane will remove salts that remain dissolved.
Coarse solids
Screens, sieves, hydrocyclones, meshes or discs depending on origin and flow rate.
Turbidity and particulates
Media filtration, specific media and safety cartridges.
Colloids and bacteria
Ultrafiltration when a finer and more stable physical barrier is required.
Dissolved salts
They require specific processes such as reverse osmosis; they are not removed by UF.
What ultrafiltration provides
- Water with very low turbidity.
- Retention of fine solids and colloids.
- Barrier against bacteria according to membrane and operation.
- More consistent quality for downstream processes.
What must be dealt with through another channel
- Salts and conductivity.
- Hardness and certain dissolved ions.
- Compounds requiring adsorption or oxidation.
- Residual disinfection of a distribution network.
Process engineering
From water analysis to a maintainable operation
Equipment is sized for actual site conditions: feedwater quality, peak flow, operating hours, available space, washwater discharge and the operator’s capabilities.
Characterisation
Analysis, turbidity, solids, SDI where applicable, variability and quality objective.
Selection
Technology, surface area, filtration grade, membrane flux, and redundancy.
Integration
Pumping, valves, instrumentation, automation, washings and storage.
Validation
Commissioning, setpoint adjustment, training and maintenance plan.
Applications
Protection and water quality for different sectors
Standard lines of treatment
- Surface water abstraction: screening, depth filtration, safety and disinfection.
- Osmosis pretreatment: filtration, cartridge filters and, where justified, ultrafiltration.
- Mains or process water: activated carbon and final filtration according to use.
Factors affecting the project
- Spikes in turbidity, solids and organic matter.
- Service flow rate and backwash water availability.
- Space, pressure, drainage and existing automation.
- Service continuity and operator capacity.
Maintenance and consumables
Quality depends on maintaining every barrier
We check pressure drops, backwash sequences, valves, instrumentation and the condition of the media or membranes. We plan consumables and cleaning to reduce downtime and prevent the system from losing capacity.
- Cartridges, bags, filter media and spare parts.
- Differential pressure and flow rate control.
- Backwashes, chemical cleans and integrity testing.
- Optimisation of existing facilities.
Coverage
Service from the Canary Islands for the islands and Africa
We develop projects in Tenerife, Gran Canaria, Lanzarote, Fuerteventura, La Palma, La Gomera and El Hierro, and coordinate supply, logistics and support for West and North Africa from the Canary Islands.

Filtration, water treatment and desalination fulfil different functions
We define the correct scope so that one stage does not promise what corresponds to another technology.
Frequently asked questions
Before installing a filtration or ultrafiltration system
What is the difference between conventional filtration and ultrafiltration?
Conventional filtration retains particles using meshes, cartridges or granular beds. Ultrafiltration employs membranes and offers a finer and more consistent separation against turbidity, colloids and microorganisms.
Does ultrafiltration remove salts from water?
No. Dissolved salts and conductivity require specific processes, such as reverse osmosis. UF can protect that process, but it does not replace it.
What data do you need to size the system?
Representative analytics, water origin and variation, hourly and daily flow rate, end use, operating hours, space, available pressure, and conditions for managing backwashes.
Does the system need backwashing?
It depends on the technology. Multimedia filters, self-cleaning filters and ultrafiltration systems require defined backwash sequences to restore capacity and maintain head loss.
When is activated carbon used in industrial filtration?
It is used mainly to adsorb free chlorine and certain organic compounds, improve organoleptic characteristics or protect sensitive processes. Its necessity, contact time and replacement frequency are determined according to the water and the end use.
What is the advantage of installing several filters in a bank?
It allows for the distribution of large flow rates, the adaptation of capacity to demand, sequential backwashing and the provision of redundancy to maintain service during certain maintenance operations.
Can you upgrade an existing installation?
Yes. We will review the point that limits flow rate or quality and propose phased changes, retaining the equipment that is still valid.
Do you carry out maintenance and supply consumables?
Yes. We provide maintenance services in the Canary Islands and coordinate spare parts, filter media, cartridges, membranes and technical support for projects in Africa.
