  • 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. What is the wastewater treatment approach of GreenPebble Tech (GPT)? GreenPebble Technologies offer a wide range of products and engineering services for its water and wastewater treatment solutions. Our focus is to deliver on sustainability, efficiency and robustness in process solutions. GPT takes a thorough overview of customers’ inlet wastewater quality, local site conditions, treatment goals, regulatory compliance etc. Depending on given inputs, basic and detailed engineering design will be considered along with commercial aspects at the project stage itself.

  • UF for Water and Wastewater Treatment | GreenPebble Technologies

    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. Applications of UF Water Treatment Plant Sewage Treatment Plant Industrial Effluent Treatment Plant Zero Liquid Discharge Sea Water Desalination Technical Specifications of GPT's UF Materials:- PES or PVDF Pore Size:- 0.03 micron Size:- 4″, 6″ and 8″ diameter and 30″, 40″ and 46″ length Potting:- Epoxy Operation:- Outside- In Module:- End Cap- UPVC, Body- uPVC Benefits of GPT's UF Excellent quality of treated water Good removal of pathogens Minimal chemical usage Consistent and high product water recovery (> 90 %) High removal of total suspended solids > 0.1 micron Longer membrane life Less fouling and plugging isssues Ability to handle higher solids Easier cleaning Simple and modular design allows low cost, compact systems Energy efficient and reliable system Effluent Treatment Plant Contact Us
