Cartridge filters,
nozzles and consumables.
Fast replacement. Operational continuity.
We supply cartridge filters, strainer nozzles, spare parts and accessories for water treatment plants, with replacement programmes coordinated with plant operation so that the plant does not stop for lack of a component.
Quality materials
Verified dimensions
Technical compatibility
Traceability
Spare parts tailored to every filtration system.
We supply high-quality filter cartridges and strainers, as well as high-performance MBBR carriers to meet the requirements of each installation.
Filter cartridges
Cartridge filters for particle retention and equipment protection, selected by micron rating, material, dimensions and operating conditions.
Filter nozzles and strainers
Distribution and drainage components for water filters, selected according to slot size, connection, material and backwash conditions.
MBBR carriers
Plastic media designed to support the growth of microorganisms that remove pollutants from water.
Strainer nozzles: how to choose the slot size
The slot size must be smaller than the finest grain in the layer it supports, so that the medium does not pass into the underdrain, and compatible with the backwash flow rate.
Technical compatibility
We check materials, dimensions, connections and service conditions before recommending a component.
Equipment protection
We select consumables to ensure effective filtration and help protect downstream processes.
Planned maintenance
We help identify critical spares and organise replacement to reduce interruption risks.
How often each component needs replacing
Cartridges: when the differential pressure reaches the cartridge’s change-out value. Granular media: when filtrate quality falls or the bed analysis indicates it. Strainer nozzles: at each bed inspection, if there is media carry-over.
Further information: Everything you need to know about cartridge filters.

Desalination and reverse osmosis
Filter cartridges for pretreatment and membrane protection in desalination plants.

Drinking water treatment
Filtration consumables and components that maintain water quality and equipment performance.

Wastewater treatment and reuse
Filtration elements and spare parts for tertiary treatment and water recovery.

Industrial processes
Consumables that protect equipment, maintain process water quality and simplify maintenance.
Filtration experience demonstrated in real-world installations.
KEIKEN’s experience in water treatment enables us to understand the technical demands of different filtration systems and the importance of selecting the right components for each process.
Answers to your questions about filter cartridges and consumables.
What information do you need to identify a consumable?
Reference, manufacturer, photographs, dimensions, material, the equipment where it is installed and operating conditions.
Can you supply compatible equivalents?
Where technically feasible, we can propose compatible alternatives after checking specifications and application.
What types of filter cartridges do you work with?
The selection can include different materials, micron ratings, lengths, diameters and configurations depending on the process.
How is a cartridge’s micron rating selected?
It depends on the contaminant, the target quality, the solids load, the flow rate and the process stage.
Do you supply nozzles and strainers for existing filters?
Yes. We need the dimensions, connection, slot, material and system characteristics.
Can you help identify a spare part with no reference?
Yes. Photographs, dimensions, equipment, function and working conditions help us find a suitable option.
How is chemical compatibility managed?
We review the fluid, concentration, temperature, pressure and component material.
Do you hold stock?
Availability depends on the reference. We can also agree safety stock for critical components.
Do you offer replacement programmes?
Yes. Consumption, minimum levels, frequency and forecasts can be defined to reduce the risk of running out of stock.
What documentation comes with the supply?
Depending on the product, this may include technical datasheets, certificates, traceability and material documentation.
Can you supply operating accessories?
Yes. We can include tools, gaskets, adaptors, mounting elements and other auxiliary components.
Do you make scheduled deliveries?
Yes. Logistics can be organised as partial or periodic deliveries according to consumption and storage capacity.

We are a B Corp company
B Corp certification independently assesses a company’s environmental and social performance, transparency and legal accountability. For us, it is more than a label: it provides a framework for our technical decisions. Every plant we design is also assessed for its energy consumption, the water footprint it helps reduce and its impact where it is installed.
