Teatro Marcello Manager: Teatro Marcello Energy Srl. Plant Location: Roma, EUR Quarter, on the road to Fiumicino Plant Type: 1 x ZE‐50‐ULH LT‐ORC Module Application: Waste heat recovery from wood‐pellet‐fueled Burkhardt gasifiers and from the cooling jacket and flue gases of the MAN engines fueled by the syngas produced by said gasifiers.  
  10. 10.   Proposal for treatment and reuse Treatment Solar Based directional solvent extraction. Very low temperature membrane‐free desalination by directional solvent extraction. Separation of salt from water with decanoic acid. Decanoic acid is a fatty acid and occurs naturally in many essential oils. We are sourcing from India.  The process involves heating the solution to 40 to 90 degrees Celsius (104 to 190 degrees Fahrenheit) that separates highly concentrated brine from the water‐acid solution. As the solution is cooled, the pure water separates out and the solvent is reused.  We are basically concentrating glycerol in water droplets. A better solvent will dissolve more water in it and therefore, the yield of water per volume of solvent is higher and requires less energy, allows for smaller systems and greater overall efficiency.  Like dissolves like, but we are looking for pairs of materials with water which exhibit asymmetric solubility. So where we want the water to dissolve in our solvents, we don’t want the solvents to dissolve in our water.  You just take a solvent. put the water in it, it dissolves out the water, contaminants are rejected, you remove that, cool the solvent back down, the water kind of precipitates out – like air is hot, it picks up water, when it cools the water drains out – and we collect that and reuse the solvent.  The plant will use Concentrated Solar Power to Heat the Water to required temperature.  Reuse The Water will be bottled and supplied to our network of Mineral Water Franchisees in UAE, Oman, Qatar, and Kuwait. We will use the water to generate electricity using solar and use it bottling the water.  Bottling 1.5 liter PET fizzy or still mineral water. We have taken into account 1 million liter/month and 5 million liter/month capacity. It is one‐off investment cost. The calculation consists of the whole project which the bottling might start immediately with. The amount is made up of all kind of supplementary costs which is necessary to carry out the project. such as planning and designing, authorization, evaluation, building and mechanical construction, taxes and contributions. Capacity of planned bottling line is 10,000 PET/hr. implementing smaller production line is not expedient because it has the best exploitable cost performance ratio. Electricity for the bottling will be generated by wind, solar and Bio‐diesel based hybrid system at the site.  The Salt and Chlorine produced will be packed in HDPE bags for supplying to India and Pakistan.  The brine water will also used for generating electricity using organic rankine cycle by utilizing Geo Thermal Energy before being disposed in to deep well.

The system components are a solar collector and a desalination tower, although thesystem can be operated with other energy sources. The desalination tower is made of six stagesand a water circulation system through the stages to avoid salt concentration. The numericalresults calculated using ambient data show that the production rate can reach 25 L/m2/d, which isby a factor of five times greater than the rate of a basin-type solar desalination unit. The water(polluted seawater and well water) laboratory tests results show that the desalination processeliminated the Coliform group bacteria and reduced the salt concentration to very low levels.

The results show that it can reach a water production rate of 25L/m2/d for a value of 4.8k Wh/m2/d of solar radiation. This represents a rate of 5.2 L/kWh m2 anda factor of five to six times greater than the tank-type distiller. The problem of salt concentrationhas been taken into consideration through the continuous water flow through the unit.

When water passes trough a second pass, residualcalcium and magnesium concentration are close to zero.Therefore 2nd-pass Ro permeate should be remineralized to achieve a residual typical hardnessof 8oD (100 mg/L CaCO3).This solution matches well drinking water requirements in low sodium, high calcium values.Irrigation waterIrrigation water is more complex, it relies on an equilibrium between sodium, calcium andmagnesium that ensure good infiltration in the soil. this equilibrium is measured by the SodiumAdsoprtion ratio (SAR) and the Electrical conductivity (EC):Boron should also be removed, as it represents a toxic poison for the plants.In order to keep a minimum EC of 0.3 dS/cm (~200 mg/L TDS), a sufficient calcium andmagnesium concentration, the second-pass RO should be avoided or largely by-passed.Therefore the ideal solution is to use a specific Boron removal ion exchange resin and then toremineralize.Process waterProcess water is a very generic term that includes all type of water that doesnt need to complywith the WHO guidelines for drinking water. Requirements are usually up to the water consumingapparatus manufacturers guidelines, like a heat exchanger, a boiler, dilution water, etc.. In

The R-TEN DLX unitsfrom R-TEN Systems are some of the most energyefficient desalination systems available. Energyconsumption for these units will vary from 3.0 to 4.5kWh per cubic meter of RO product depending uponthe system size.Labor - Even though the R-TEN units are highlyautomated, labor is still necessary for routineoperating and maintenance activities. Highly skilledlabor is not necessary since R-TEN Systems can trainany operator who meets basic qualifications. Ingeneral, the SOLAR DESALINATION lead operator should be wellversed in the operation of mechanical and electricalequipment. They should be capable of followinginstructions to perform simple troubleshooting tasks,routine test procedures, and periodic membranecleaning activities.Membrane Replacement - Modern RO membraneelements are designed for long life but they do needto be replaced periodically. Replacement interval ishighly variable depending upon local operatingconditions. Typical membrane life is three to fiveyears although there are documented cases ofmembranes lasting well over ten years.Consumables - Operation of the SOLAR DESALINATION requires theuse of certain consumable items including filter aidinjected into the feed stream to improve prefilterperformance, scale inhibitor to prevent fouling of theRO membrane, filter cartridges, and membranecleaning chemicals.Spare Parts - While R-TEN uses high qualitycomponents in constructing its R-TEN units,various parts of the SOLAR DESALINATION are apt to wear or failover time and spare replacement will be necessary.Capital Amortization - The final cost factor is theamortization of the capital investment. R-TEN’s

Our first SOLAR DESALINATION is still operatingafter sixteen years of service.TYPICAL O&M ACTIVITIESThe tables on the following pages list the operationand maintenance activities for some of our mostpopular size plants.System Monitoring - Any SOLAR DESALINATION system requiresthe operator to check and record various criticaloperating parameters on a daily basis. This data isinvaluable when it becomes necessary to troubleshootsystem performance. The R-TEN DLX unitshave automatic data logging which minimizes thistask.Housekeeping - This covers the day-to-day tasksnecessary to keep the system clean and orderly thusprolonging the life of the system and facilitatingmaintenance activities.Filter Changes - The R-TEN systems haveseveral filtration steps utilizing disposable media(cartridges and bags). These need to be changedperiodically.Instrument Calibration - Successful operationrequires dependable data. Instruments on theR-TEN systems should be calibrated on amonthly basis.Surface and Tank Cleaning - The surface of the tankused in the R-TEN units will become fouled overtime with suspended solids, organic material, andbiofilm. The membrane is cleaned periodically witha chemical cleaning process. Actual cleaning intervalis a function of the feed water quality.Membrane Replacement - Typical membrane life isthree to five years.Component Repair - Man hours should be budgetedfor the non-scheduled repair or replacement of worncomponents.Important milestonesSTAGE  Duration RemarksFEED Study  4‐WeeksEngineering and Design of Plant  8‐WeeksDetailed Engineering and Design of Equipment 12‐Weeks Can be parallel with Plant
