Gpt Is A Sustainable Solutions Provider Engaged In Designing And Manufacturing Industrial Wastewater And Effluent Treatment Plant In India. Gpt'S Proprietary Membrane Distillation (Md) Process Is A Specifically Designed Innovative Membrane Process That Helps To Treat Wastewater With High Salinity Efficiently, Economically And Sustainably. We Offer Md As Part Of Etp And Zld Plants To Improve Energy Efficiency And Operational Effectiveness. The Md Process Recovers Product Water From A Feed Source At Significantly Lower Energy Compared To Conventional Methods. The Technology Is Ideally Suited For Industrial Wastewater And Complex Effluent Treatment Applications. Md Is Also Considered To Be Sustainable Membrane Technology For Low-Temperature Dewatering Of Food And Beverages, Zld, Brine Minimization And Desalination Etc To Meet Regulatory Compliances, Reduce Opex And Increase Water Usage Efficiency. ​ Md Can Be A Promising Alternative To Conventional Thermal Processes. Md Process Eliminates The Need For Complex And Expensive Evaporation And Crystallization Unit Operations. Moreover, The Process Economics Becomes Extremely Favourable If Waste Heat Or Natural Heat Source (I.E. Solar Evaporation) Are Available- Reducing Per Unit Cost Of Product Water And Thereby Achieving Integrated, Compact, Economical And Sustainable Process Solutions.

Ultrafiltration (Uf) Is A Low-Pressure Membrane Filtration Process For Water And Wastewater Treatment To Remove Suspended Solids, Colloids, Bacteria And Viruses. Uf Is Typically A Hollow Fiber Configuration Where Feed Water Flows Either Inside The Fiber (Inside-Out) Or Outside (Outside-In) Of The Fibers. Typical Pore Size Of The Uf Membrane Is 0.05 To 0.3 Microns And Operating Pressure Is In The Range Of 3 To 8 Barg (300 To 800 Kpa). Suspended Solids, Particles, Colloids And Solutes Of High Molecular Weight Are Effectively Rejected, While Water And Low Molecular Weight Solutes Pass Through The Membrane. Gpt'S Proprietary Uf Membrane System Removes The Need Of Spacious And Chemical-Consuming Coagulation, Flocculation And Settler Unit Operations And Thus It Is Compact, Modular And Sustainable. Ideally Uf Is Placed As A Pretreatment To Nanofiltration (Nf) Or Reverse Osmosis (Ro) System. Greenpebble Technologies Uses Custom-Made Uf Modules That Are Giving High Water Flux, Less Fouling, Longer Membrane Life And Cost Advantage. Our Ultrafiltration (Uf) Membrane And System Provides Flexibility To Operate In A Range Of Conditions That Can Be Optimized For A Specific Water Source To Reduce Operating Costs.

Reverse Osmosis (Ro) Is A Robust And Superior Membrane-Based Technology That Effectively Removes Nearly All Ions And Dissolved Salts From Water. ​ Ro Also Removes Natural Organic Substances, Pesticides, Pathogens And Suspended Solids. Ro Is Particularly Effective When Used In Series With Multiple Units. ​ Greenpebble Technologies Is A Manufacturer And Supplier Of Industrial Ro Plant System Used For Municipal Sewage And Effluent Treatment Plants, Zld, Wastewater Recycle And Reuse And Desalination Applications. We Provide Integrated And Containerised Ro Plants With Capacities Ranging From 0.5 To 50 M3/Hr Capacities. Depending On The Application And The Quality Of Water, There Are Several Versions Of Ro Plants Namely- Low Salinity Low Pressure Ro Plant, Brackish Water Ro (Bwro), Sea Water Ro (Swro). ​ Standardized 4″ And 8″ Diameter Commercial Ro Membranes From Reputed Manufacturers Are Used In Ro Plants For Brackish Water And Sea Water Desalination Applications. ​ Our Thoroughly Designed, Assembled And Factory Tested Ro Plants Demonstrated Excellent Process Performance With Excellent Reliable And Robust Operation.

Microfiltration (Mf) Is The Most Basic Form Of Thin Layered Semi-Permeable Membrane Based Process To Treat Water And Wastewater. Mf Process Can Be Used To Remove Suspended Solids, Pathogens And Other Macromolecular Compounds Which Are Responsible For Bad Taste, Odor Or Color. ​ The Main Driving Force For The Separation Is Hydraulic Pressure (Typically 1-4 Barg) Applied To The Feed Side. The Pore Size Of Mf Membranes Is In The Range Of 0.03 To 10 Microns. ​ Gpt'S Mf Products Are Made From A Robust And Efficient Polymeric Material. It Gives Enhanced Product Water Quality With Significantly Less Chemical And Energy Usage. ​ There Is Growing Concern Over Effective Pretreatment Of Influent Stream Prior To Inlet To Water Recovery Stages Of Nanofiltration (Nf) And Reverse Osmosis (Ro). Having Mf As Pretreatment Helps In Limiting Number Of Chemicals That Are Added To Feed Stream. By Removing Pathogens, Mf Process Can Help Achieve The Objective Of Reducing Chemical Addition Processes Such As Chlorination And Dichlorination.

Nanofiltration (Nf) Is A Membrane-Based Process To Effectively Remove Multivalent Ions, Pathogens, Suspended Solids, And Larger Colloids In Wastewater And Effluent Treatment Systems. Nf Membranes Have A Nominal Pore Size Of Approximately 0.001 Microns And An Mwco Of 1,000 To 100,000 Daltons. In Order To Obtain Clear Product Water Through Such Membranes, It Is Necessary To Push Water At Higher Operational Pressure Than Microfiltration (Mf) Or Ultrafiltration (Uf). ​ Typically Operating Pressure For Nf Is Near 6-15 Barg (600-1500 Kpa). Nanofiltration (Nf) Is An Efficient Membrane Process For Water Softening And Helps Remove Hardness From Water Which Makes The Nf Process Suitable For Pretreatment To Reverse Osmosis. ​ Greenpebble Technologies (Gpt) Selects And Designs Proprietary Nf Membrane Systems As Part Of Its Water Treatment Design Strategy Depending On The Requirement And End-Use.
