Integrated solutions, from study to commissioning

Six areas of expertise to meet all your industrial needs.

• Industrial water treatment

  Design and construction of tailor-made plants: reverse osmosis, ultrafiltration and demineralisation for your process water.

  Raw water is almost never usable as-is: hardness, chlorine, dissolved salts and suspended solids scale exchangers and foul membranes. We size the treatment chain from a real analysis of your water and your flow rates rather than from a catalogue — 5 to 20 m³/day for compact reverse osmosis, and up to 150 m³/day for ion-exchange demineralisation, reaching a residual conductivity below 0.2 µS/cm.

• Wastewater treatment

  Biological treatment plants and industrial effluent recycling, from sizing through to operation.

  An effluent is treated for two reasons: discharge compliance, which sets a minimum target, and economics — past a certain volume, treated water becomes a resource again. Activated sludge, MBR/MBBR and polishing filtration are selected according to the real load and how much it varies. Our containerised modular plant covers 50 to 400 m³/day using activated sludge with filtration, with no heavy civil works and relocatable if your site changes.

• Air treatment

  Filtration, purification and air control systems for healthy, compliant industrial environments.

  Effective filtration is built in stages: pre-filters capture coarse particles and preserve the terminal filters, which drives running cost as much as performance. Our systems reach HEPA H13 efficiency — at least 99.95% of particles at the most penetrating size — for air flow up to 10,000 m³/h, with remote monitoring of pressure drop so filters are replaced at the right moment.

• Instrumentation

  Supply, calibration and integration of measurement and control instruments to run your processes with absolute precision.

  An installation drifts slowly: a rising membrane pressure, a climbing conductivity, a pH out of range. None of these trigger a shutdown, but they wear equipment and degrade quality. The point is therefore not to add sensors but to install the right ones at the right places, with a calibration plan — an instrument whose calibration is never checked eventually produces a false reading that is trusted.

• Maintenance services

  Preventive and corrective maintenance, spare parts and technical support to guarantee the availability of your installations.

  Preventive maintenance does not eliminate failure: it moves the intervention to a moment you choose rather than one you suffer. Corrective work depends mostly on what was prepared beforehand — availability of membranes, resins and filters, whose lead time often exceeds the intervention itself. On a treatment plant, downtime is never confined to the failed equipment: it halts the production it feeds.

• Industrial solutions

  Turnkey solutions and support across your entire production chain, from initial study to commissioning.

  Four stages, with no change of contact: on-site study and audit, tailor-made design and sizing, construction and installation by our teams, then commissioning with training for your operators. Founded in 2015, SAFWAT brings these six disciplines under one roof, which avoids having to coordinate several suppliers on a single installation. We work in food and beverage, pharmaceuticals, industry and with municipalities, across all of Tunisia — from Tunis to Sfax, Sousse, Bizerte, Gabès and Nabeul.
