Forward Osmosis Module Forward Osmosis for Water and Wastewater Treatment Forward Osmosis (FO) Advanced Membrane Separation using Forward Osmosis Technology GreenPebble Technologies is an innovation-driven water and wastewater treatment solutions provider based in India. We design, manufacture and supply proprietary Forward Osmosis membrane, module and plant systems - for applications such as ZLD, wastewater treatment and recycle, seawater desalination, industrial effluent treatment plants etc. ​ Forward Osmosis (FO) is an advanced and sustainable membrane separation process, where a semi-permeable thin-film composite membrane generates water flux using a concentration gradient across the membrane. This way it is possible to recover, concentrate, separate or purify valuable feed sources and generate fresh water with minimal energy and pressure requirements. ​ FO is considered to be promising technology due to its operational and process-related advantages over conventional technologies. ​ As FO is relying on osmotic pressure generated by concentration gradient across the membrane- to extract clean and fresh water from feed source-, unlike any other pressure-driven membrane process, there is no need to apply additional hydraulic pressure on a feed side. ​ In FO, the water recovery is accomplished using concentrated draw solution to generate a concentration gradient across the membrane, which gives recovered water mixed with draw solution. Essentially, FO requires a subsequent draw solution regeneration step where the separation of product water and draw solution is accomplished. The draw recovery section is an essential step for the continuity of integrated operation in FO. ​ GPT uses a proprietary arrangement of membrane system along with FO to recover product water and reconcentrate the draw solution. Depending on feed source, inlet quality parameters, and overall treatment goals, GPT customizes the plant configuration to regenerate draw solution including RO , NF or membrane distillation (MD) . ​ Applications of Forward Osmosis (FO) ​ Brine Minimisation for RO Concentrate Effluent Treatment Plant ZLD Water and wastewater treatment, recycle and reuse Dewatering or concentration of high-value product stream Sea Water Desalination Concentration and separation of food, beverage or pharma products Resource recovery of valuable products or minerals ​ Our pilot and commercial results showed successful outcomes for our clients in achieving around 70-80% of water recovery and a 50% reduction in energy consumption. ​ Advantages of Forward Osmosis (FO) High water recovery Low operational pressure Simple, easy and integrated design Minimized waste Low energy consumption per unit of water recovered Low capital investment Low operation and maintenance costs Less fouling and scaling Longer membrane life Ability to treat complex wastewater Modular structure Forward Osmosis Technology Applications of Forward Osmosis Contact Us

Ultrafiltration (UF) Membrane System Assured and Reliable Purification for Water and Wastewater Treatment Plants 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.

Microfiltration (MF) Advance membrane separation for excellent filtrate quality 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. ​ Applications of Microfiltration (MF) Pretreatment or Concentration of beverages and pharma products Recovery of biologically aerated sewage water Industrial effluent treatment Oil-Water Separation Pretreatment of nanofiltration or reverse osmosis in desalination Solid-liquid separation for pharma and biotech industries Effluent Treatment Plant Contact Us

Packaged Desalination Plants Sustainable Desalination Solutions with Seawater and Brackish Water Treatment Plants Packaged Desalination Plants GPT is an innovation driven water and wastewater treatment plant manufacturer, providing sustainable and energy-efficient process solutions. ​ As the availability of fresh water become scarce, it is ever more important to search for new avenues of drinking water. ​ Desalination is a separation process mainly used to recover fresh water by reducing salt content from saline water- either sea water or brackish water. ​ There are several ways to accomplish desalination however, conventionally this have been done by boiling the salt water and then condensing to get fresh water. Thermally driven technologies require metallic evaporators that flashes or evaporates sea water to obtain product water. However fouling and scaling are some of the biggest challenges in the operation of thermal processes which eventually leads to high operation and maintenance costs. ​ Currently rapidly growing and more common way to desalinate sea water is based on pressure-driven membrane operation such as Reverse Osmosis (RO) . ​ Depending on water quality RO based desalination process is called Brackish Water Reverse Osmosis (BWRO) and Sea Water Reverse Osmosis (SWRO). It is relatively cost-effective, energy efficient and robust approach to get product water. ​ Advantages of GPT's packaged desalination plant: Simple Operation Less Capital Intensive Low operation and maintenance costs Good product quality in compliance with WHO standard Modular configuration Robust technology ​ Our seawater desalination water treatment plant consists of: Intake system Depth filters pH adjustment and dosing system Ultrafiltration system Antiscalent and antifoulant dosing High Pressure Pumps Energy Recovery Device BWRO or SWRO or Forward Osmosis membrane array Polisher Unit along with Product Water Remineralization CIP system Membrane Filtration Reverse Osmosis

Pervaporation System Advanced Membrane Separation for Resource Recovery Pervaporation is a membrane molecular separation technology- utilised for selective permeation of diffusive component from aqueous-organic mixtures. ​ The pervaporation process is mainly used for the removal of the solvent from a mixture to produce a concentrated feed stream and a purified stream of the solvent. Pervaporation system is ideally suited for resource recovery and waste valorisation for industries and can be a part of industrial water and wastewater treatment setup. ​ Pervaporation offers numerous advantages in terms of energy-efficiency, sustainability and cost-effictiveness than other conventional technologies. ​ GPT is a manufacturer, supplier and technology solutions provider of proprietary pervaporation system. ​ The pervaporation process is carried out in a dense polymeric membrane layer that are functionalized with either hydrophilic or organophilic which is responsible for physico-chemical separation and mass transport of molecules through the membrane. ​ In order to achieve separation, a vacuum or partial vacuum is applied on one side of a pervaporation membrane.
