RO Demineralisers, Medium Flow

1. RO Demineralisers, Medium Flow Demineralisers Medium Flow. Units available Mod.4VA0X00:Cancelled • Many membranes replaced in guarantee period. • Corrosion problems due to high salinity • Chlorine remover filter insufficient (chlorine damages the membranes) • Few pre-treatments available

2. RO Demineralisers Medium Demineralisers Medium Production Capacity. Units available Mod.4DAXX00: Available • Equipments to process water from wells and brackish water, suitable to treat up to 2.500 mg/l (low salinity) and 9.000 mg/l (high salinity) of TDS, respectively. • It can be mounted in a small cabinet Mod. 4045500 • Optional production capacity increase with adittional membranes (1-4) • Options: Chlorine remover filter, silex filter, iron remover filter, organic matter filter. Biocide doser, Bisulfite and water softener for boilers. Iron remover Filter Silex-antracite Filter Chlorine remover Filter Organic Matter Filter Biocide Doser Bisulfite Doser

3. 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.

4. RO Demineralisers Medium Models 4DAXX00. 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:

5. RO Demineralisers Medium Just like a car, the models 4DA have two types of alarms to inform us about any possible failure and its seriuosness. Models 4DAXX00. Example of anomaly

6. 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

7. RO Demineralisers Medium Demineraliser. Size. Height 2.000 mm It is possible to be installed in cabinet Ref. 4033500 (size with cabinet: Height 2.100 mm x Width 1.500 mm x Depth 900 mm Width 480 mm Length 1.550 mm

8. RO Demineralisers Medium Demineraliser. Available Configuration Assembly in Plant Configuration

9. 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. 4.-Every 6 months To clean the small tanks of anti-scalant and backwash water. 3.- Every 3 months To check the condition of the filters (FS1 & FS2), if necessary they should be changed.

10. RO Demineralisers Medium Example of calculation of Antiscalant vs Water Softener 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 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

11. 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

12. RO Demineralisers Medium Difference between antiscalant and water softener. Antiscalant doser system + Antiscalant drum Water softener + Salt

13. RO Demineralisers Medium Range: Low salinity: 0 ppm– 2.500 ppm High salinity : 2.500 ppm – 9.000 ppm All R.O. equipments must be installed with a pretreatment stage according to the intake water quality !
