What is industrial wastewater? Industrial wastewater is the contaminated water generated after industrial or commercial activities in various industrial sectors. Today almost all industries require fresh water for their regular commercial activities. Fresh water is generally extracted from natural resources such as rivers, groundwater, lakes or the sea. Industries use water for various purposes including processing, reaction, formation, purification or separation of the desired product. The undesired or excess water resulting after industrial use contains various contaminants in a suspended or dissolved form. Each industry has its own unique characteristics of wastewater that needs to be carefully evaluated to suit its recycling requirements. Sources of Industrial Wastewater In industries, water is used in various parts of the production process such as utilities, processing, cleaning, washing, human consumption etc. The wastewater is emanating from primarily two sources: effluent wastewater from industrial processes and municipal sewage due to human consumption. It is important to understand the quality and quantity of contaminants vary significantly in both industrial wastewater and municipal sewage. Depending on the nature and quantity of pollutants, the treatment approach and process will be decided. What are the treatment methods for industrial wastewater? The contaminant levels and the nature of contaminants vary significantly across industries. In general, industrial wastewater contains a mix of organic and inorganic wastes, dissolved ions, suspended solids, biological components, pathogens or microorganisms etc. The industrial wastewater effluent treatment plant undergoes multiple treatment steps to recover the bulk of wastewater and reduce effluent volume. These include primary, secondary and tertiary wastewater treatment followed by a minimum or zero liquid discharge system. Below are some examples of various processes that covers in wastewater treatment: Primary treatment of wastewater involves: Coarse and fine screening Coagulation and flocculation Primary settler/ clarification tank Dissolved Air Floatation (DAF) Oil skimmer Sludge collection tank Secondary treatment of wastewater consists of: Biodegradation of industrial effluent/ biological aeration Anoxic/anaerobic system Secondary settling tank Activated sludge recycling tank Tertiary treatment of wastewater covers: Granular media filtration/sand filtration Activated Carbon Filter Micron Cartridge Filter Ultrafiltration or Nanofiltration Reverse Osmosis system Ion Exchange resin Disinfection system Industrial Wastewater Treatment plant Design The industrial design and engineering of an industrial wastewater treatment plant depend on multiple factors i.e. basic inputs, outlet water quality requirements, regulatory compliance etc. After basic process design concepts and technology selection, the most important and crucial steps of basic and details engineering starts followed by equipment sizing and technical specifications. The advanced design is an incremental and slow-moving process from idea and feasibility study to successful commissioning, performance guarantee test and final hand-over.

Polluted Water Wastewater Treatment in Textile Industry Textile Prioritizing ESG Goals using Advanced Wastewater Treatment Plant Systems We have dedicated process and product solutions that are suitable for harsh and demanding conditions of textile industries. ​ The textile industry is traditionally water intensive sector and generates effluent with high amount of TDS, TSS and COD. Therefore, it is extremely important to adopt new technologies to effectively treat and recycle the effluent to meet strict environmental standards and achieve water sustainability. ​ Conventional industrial wastewater treatment technologies consist of multiple stages of pretreatment , Reverse Osmosis , Evaporator and Crystallization system. They require high operational footprint, high capital and O&M costs. Additionally, they are difficult to maintain and gives overall high cost of ownership. ​ GPT’s patented SBS© system is based on Forward Osmosis (FO) technology which offers multitude of advantages of low energy consumption, less fouling, less chemical use while providing more than 70% water recovery. ​ Some of the typical solutions that we offer are as follows: - Zero Liquid Discharge - Caustic Recovery - Dyes and PVA Recovery - Color Removal - Raw Water Treatment Plant - Wastewater Treatment Plant - MBR Technology for ZLD ​ We can provide waste water treatment solutions with new designs or with retrofitting improved processes. ​ Our advanced membrane filtration product portfolio can deliver efficient, cost-effective, environmental friendly and low energy solution compared to conventional treatment methods. ​ Contact us to get a free evaluation of your specific requirement at the earliest. ​ Water Treatment Solutions Contact Us

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
