RO Demineralisers Medium Models 4DAXX00. Main Features: Antiscalant doser instead of a water softener with salt. Antiscalant automatic mixture preparation. Backwash with demineralised water instead of feeding water. Advantages due to the use of antiscalant: Ecological: No brine from the water softner regeneration Logistics and easy use: no need to stack salt bags and simplicity Cheaper: antiscalant is cheaper than salt consumption Expansion of the action capacity: wide espectrum Balance in the ratio production/surface & reject/surface of the membrane compared with the old existing equipments.

Main Features: Quality of components: Programmable PLC Siemens S7-200 Centrífugal Pump Grundfos Metering Pump Prominent Stainless steel frame quality AISI-304 Piping of High salinity range in stainless steel AISI-316 Toray membranes: TMG10 (Low salinity), TM710 (High salinity) Production can be upgraded just by adding membranes to the existing equipment (no need to buy a full new system). Suitable cabinet assembly Wide range of pre-treatments available:

RO Demineralisers Medium Models 4DAXX00. Balance Situation Customer How can we reach the balance between the three different interests? TAS Equipment

RO Demineralisers Medium Models 4DAXX00. Anomaly a) Minor Anomaly Those that require a TAS action, but they are not critical for the equipment operation. In this case, the equipment will alert with a buzzer, being this information registered in the PLC. From this moment, the customer has 10 days to inform to Istobal TAS, so they can proceed to the repair this anomaly, during these 10 days the equipment will keep on working. After this time the equipment will stop automatically, protecting itself from severe damages. Example: Antiscalant dosing failure. b) Serious Anomaly Those that require a TAS action, but being critical for the operation of the equipment. Therefore the system will stop immediately in order to avoid irreversible and expensive damages to the customer. Ejemplo: Water shortage, so the equipment must stop in order to avoid damages in the pump.

RO Demineralisers Medium Models 4DAXX00. Example of anomaly Just like a car, the models 4DA have two types of alarms to inform us about any possible failure and its seriuosness. CAR DEMINERALISER TYPE OF ALARM EXAMPLE ACTION NOT CRITICAL Windscreen wiper water shortage Amber light: to stop in a few miles Flow of demineralised water production, product dosing. Failure warning, failure record and equipment stop after 10 days. CRITICAL Motor oil shortage, brake fluid shortage Red light: immediate stop Water shortage, levels, overcurrent. To stop the equipment

RO Demineralisers Medium Models 4DAXX00. Main Features: Buzzer included to alert the customer about the failures. The equipment must recognize the adverse conditions to assure a long operational life. The demineralisers are equipments overlooked by the customer (is a non productive equipment) and usually there is not a preventive maintenance of these installations. The equipment will stop only if there is an imminent risk to its operating life, avoiding irreversible and expensive damages. The customer must be informed of any anomaly (critical or not) without decreasing the business. Light Alert Buzzer

RO Demineralisers Medium Maintenance of Demineralisers 4DAXXXX 1.- Daily maintenance To check the level of chemical product. 2.- Every week To check and to take note of pressures and flows. 3.- Every 3 months To check the condition of the filters (FS1 & FS2), if necessary they should be changed. 4.- Every 6 months To clean the small tanks of anti-scalant and backwash water.

RO Demineralisers Medium Example of calculation of Antiscalant vs Water Softener Antiscalant dosage Consumption of antiscalant product: Daily need of water: 21 m3 at 70 ºHF (39,2ºHD). “High” dosage of product: 5 mg/L = 5 g/m3 Daily product consumption: 21m3 x 5 g/m3 = 105 g/day = 0.105 kg/day 1 carafe 10 L = 13 kg So 1 carafe of 10 litres of antiscalant will last: 13 kg / 0.105 kg/day = 124 days Water softener 2x100 litres Salt Consumption: Daily need of water: 21 m3 at 70 ºHF (39,2ºHD). Necessary regeneration of the water softener every 9 m3 Number of regenerations per day: (21m3/day) / (9m3/ regeneration) = 2.3 regenerations /day Consumption of salt per litre of resin in every regeneration: 0,2 kg/Litres of resin Consumption of salt in every regeneration: 0,2 kg/Litre of resin x 100 Litres of resin = 20 kg of salt per regeneration Salt consumption per day: 2.3 regenerations / day x 20 kg of salt/regeneration = 46 kg/day Salt consumption in the same period of time (124 days): 46 kg/day x 124 days = 5. 704 kg = 228 sacks of 25 kg

RO Demineralisers Medium Example of calculation of Antiscalant vs Water Softener Conclusion: In 124 days of use: 5.704 Kg of salt = 1 bottle of 10 L (13 Kg) Make yourself your calculations: Price/kg Salt x 5.700 kg salt = Euros spent on salt versus PVP 10 L Antiscalant carafe = 189 ,00 Eur
