RO Demineralisers Medium Models 4 DAXX 00. Main Features: ü Antiscalant doser instead of a water softener with salt. ü Antiscalant automatic mixture preparation. ü Backwash with demineralised water instead of feeding water. ü Advantages due to the use of antiscalant: § § ü 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.

RO Demineralisers Medium Models 4 DAXX 00. Example of anomaly Just like a car, the models 4 DA 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 Water Treatment Division

RO Demineralisers Medium Models 4 DAXX 00. 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. Buzzer Light Alert Water Treatment Division

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

RO Demineralisers Medium Example of calculation of Antiscalant vs Water Softener Antiscalant dosage Water softener 2 x 100 litres Consumption of antiscalant product: Salt Consumption: – Daily need of water: 21 m 3 at 70 ºHF (39, 2ºHD). – Necessary regeneration of the water softener every 9 m 3 – Number of regenerations per day: (21 m 3/day) / (9 m 3/ 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 – Daily need of water: 21 m 3 at 70 ºHF (39, 2ºHD). – “High” dosage of product: 5 mg/L = 5 g/m 3 – Daily product consumption: 21 m 3 x 5 g/m 3 = 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 Treatment Division

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 Water Treatment Division
