IOWater - International News

51 Europe - France Information: Tel.: +33 5 55 11 47 70 - E-mail: communication@oieau.fr The News N° 29 IOWater was once again actively solicited by industrials in 2018 to carry out audits with a view to optimising water treatment pro- cedures. The technical sectors concerned were highly varied: l Tanneries (BASTIN, PECHDO, etc.). l Agrifood (LACTALIS, TERRA LACTA, etc.). l Chemical industry (SAIPOL, LYON- DELL-BASELL, CHEVRON, etc.). l Refineries and energy producers (EDF, TOTAL, ORANO, CHEVRON, etc.). l Automobile industry (VOLVO TRUCKS, etc.). Diagnoses and support from IOWater in the industrial sector included the following mis- sions: ➊ Accompaniment on strategic issues: l Adaptation strategies and action plans. l The most economic, sustainable use of water. l Natural water retention measures. l Reuse of water, multicriteria approaches. l Ecosystem services and biodiversity of aquatic environments. l Institutional discussions and cooperation. ➋ Expert and advisory missions: l Bibliographic summaries. l Rapid, long-distance analyses and/or on-site in case of malfunction, regulatory modifications, etc. l Diagnosis of treatment unit design and operation, and definition of directions for improvement. l Technico-economic optimisation (reac- tants, energy, etc.). l Characterisation of effluents (hard COD, etc.). l Eco-engineering, nature-based solutions, life cycle analyses, adaptation of planning and management by river basin. ➌ Research test and technology deve­ lopment programme: l Treatability tests of clean industrial water and waste water. l Promotion of IOWater’s existing teaching and technological platforms. l Production of pilots in maritime contain- ers useable on any industrial site. ➍ Set-up and joint participation in calls for European Union and international projects and their production. Network- ing of stakeholders in the water sector on global level, mobilising expertise capaci- ties of both parties. ➎ Competence assessment: conception and production of training plans. Reco­ gnition of competencies and training paths. Method for validating competen- cies (certification). A non-exhaustive list of missions in 2018 includes: PECHDO tannery: diagnosis of the indus- trial effluent treatment unit: ➥ Detailed visit with the operator. ➥ Production of a chrome precipitation curve. ➥ Carrying-out of jar tests. ➥ Report of recommendations. LACTALIS: Quantification of impact of alti- tude and temperature on calculations of oxygen requirements. Measurement protocol for oxygen transfer in clear water. SAIPOL, Avril Group: Diagnosis of the industrial effluent treatment unit: ➥ Validation or not of STEP sizing. ➥ Validation or not of STEP equipment. ➥ Recommendations to optimise operation and settings. TOTAL group: Production of a bibliographic, technical and scientific overview of the anal- ysis methods of free chlorine and associated regulation of chlorine for semi-closed circula- tion cooling systems. VOLVO TRUCK: Audit of 2 demineralisation chains in production and regeneration phase: ➥ Optimisation of all settings, acid and caustic soda dosage, dilution, calibration of probes. ➥ Assessment of the current state. ➥ Technical report of all of the measures and controls carried out. ➥ Diagnosis of the treatment station with a view to reusing water. 4 Diagnosis and technical support for industrials BETTER WATER MANAGEMENT IN INDUSTRY
