- Industrial Water and Wastewater Treatment: An Overview
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.

- Membrane Distillation in India | GreenPebble Technologies
Membrane Distillation (MD) Resource Recovery and Brine Minimization using Sustainable and Advance MD 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 relies on water vapour transport through porous hydrophobic membranes using partial vapour pressure difference across the hydrophobic membrane. 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. Membrane Distillation (MD) Advantages Low pressure and low-temperature operation Low operating costs High water recovery up to 90% Excellent product water quality Simple operation and less maintenance Modular configuration Less fouling Multimode operation Capable of treating a wide range of feed characteristics Membrane Distillation (MD) Applications: Acid Recovery Zero Liquid Discharge Valuable Minerals Recovery Brine Minimization Wastewater Recovery and Recycle Custom Solutions using Membrane Distillation Contact Us
- MBR for Wastewater Treatment & ZLD in India | Greenpebble Technologies | Gujarat
MBR Sewage Treatment Plant Design MBR Working Principle MBR Membrane Module with Skid MBR Membrane Module MBR Hollow Fibers Reinforced Hollow Fiber Membrane for MBR MBR Sewage Treatment Plant Design MBR Working Principle Membrane Bioreactor (MBR) for Wastewater Treatment and ZLD Sustainable and Reliable Wastewater Treatment using MBR Technology GreenPebble Technologies (GPT) is India's leading MBR membrane manufacturer and supplier. We are an innovation-driven water and wastewater treatment plant manufacturer and supplier. Our compact and efficient sewage and effluent treatment plants deliver on improved water and energy efficiency with minimal life cycle costs. Membrane Bioreactor (MBR Technology) is made up of the combination of submerged type Ultrafiltration (UF) membrane filter in either hollow fiber or flat sheet configuration. MBR system also integrates biological aeration comprising of activated sludge to decompose incoming nutrient load. This configuration significantly improvises overall operational effectiveness and reduces space requirements. GreenPebble Technologies’ proprietary MBR system utilizes reinforced PVDF hollow fiber membranes as a submerged module. GPT's MBR modules are suitable for a variety of applications and capacities and they come with flexible designs for easy installation. GPT's MBR plant system integrates a submerged hollow-fiber membrane with a specifically designed bioreactor system that breaks down complex substances in wastewater and the MBR membrane filters out product water. Our MBR system can replace a conventional wastewater treatment system comprising multistage operations with a more modular, easily deployable and integrated solution that is easily maintained and operated. GPT's proposed MBR system consists of a primary treatment screening stage followed by MBR membrane module- thus reducing operational footprint and improving process performance. To get even further purification, it is possible to treat MBR product water by adding a Nanofiltration (NF) or Reverse Osmosis (RO) stage. Solid substances larger than 0.03 microns are removed by the membrane and clear treated water, having almost no solid particles and harmful pathogens- is recovered. Due to its increased reliability and excellent product water quality, MBR is an ideal technology to meet strict environmental compliances. Membrane Bioreactor (MBR) technology is mostly preferred as it eliminates the requirement of additional settling tanks and reduces the overall asset footprint compared to the conventional size and it results in an overall cost-effective solution.
