Microfiltration (MF) is a fundamental membrane process employed in water and wastewater treatment to effectively separate suspended solids, pathogens, and other macromolecular compounds that contribute to undesirable taste, odor, and color. Operating under hydraulic pressures typically between 1 to 4 barg, MF utilizes membranes with pore sizes ranging from 0.03 to 10 microns, making it suitable for diverse applications across various industries. Its robust polymeric construction ensures improved water quality with reduced chemical and energy consumption. The use of MF as a pretreatment step in processes like nanofiltration and reverse osmosis helps in minimizing chemical additives. It finds application in beverage and pharmaceutical product concentration, biologically aerated sewage water recovery, industrial effluent treatment, and oil-water separation, among others. MF provides a reliable solution for the solid-liquid separation needs of pharma and biotech industries, enhancing overall water recovery efficiency.

The Ultrafiltration (UF) Membrane System by Green Pebble Technologies is designed for effective water and wastewater treatment. Utilizing a low-pressure membrane filtration process, it efficiently removes suspended solids, colloids, bacteria, and viruses with typical pore sizes of 0.05 to 0.3 microns. This system operates under pressures ranging from 3 to 8 barg (300 to 800 kPa), enabling the passage of water and low molecular weight solutes while rejecting larger particles. The proprietary design eliminates the need for chemical-intensive treatments, which enhances its sustainability and modularity. The hollow fiber configuration supports both inside-out and outside-in water flows, ensuring high water flux, minimal fouling, and long membrane life. It's an efficient pretreatment stage for nanofiltration and reverse osmosis, offering adaptability for diverse water sources and reducing operating costs. Comprised of materials like PES or PVDF, the system provides a range of size options and features components constructed from UPVC, benefiting sectors that demand consistent water quality.

Green Pebble Technologies, based in India, is a leading provider of Membrane Bioreactor (MBR) systems, essential for modern wastewater treatment and zero liquid discharge applications. Their MBR systems utilize reinforced polyvinylidene fluoride (PVDF) hollow fiber membranes distinguished by high mechanical strength and energy efficiency in low-pressure environments. These systems integrate submerged ultrafiltration membrane filters with a specifically designed bioreactor, employing activated sludge to decompose nutrients, thus enhancing overall operational efficiency while minimizing the spatial footprint. The advanced MBR modules can efficiently replace conventional multistage wastewater treatment setups with a single, modular solution, offering flexibility across various applications and capacities. Notably, these modules provide high flux and long intervals between chemical washes, making them an excellent choice to meet stringent environmental regulations. The MBR technology not only reduces the need for settling tanks but also manages high sludge retention time, delivering immaculate treated water ideal for regulatory compliance in sewage and effluent treatment processes.

Nanofiltration (NF) is a membrane technology used for effective separation of multivalent ions, pathogens, and large particles in wastewater treatment systems. It typically features a nominal pore size close to 0.001 microns and a molecular weight cut-off (MWCO) between 1,000 to 100,000 daltons. NF membranes operate at pressures between 6-15 barg (600-1500 kPa) and are adept at softening water by removing hardness, making them invaluable in pretreatment for reverse osmosis processes. Green Pebble Technologies designs bespoke NF systems tailored to specific water treatment needs. NF's applications span diverse fields including biochemical separation, resource recovery, dye processing, and flavor extraction in food and beverage industries. This process supports zero liquid discharge strategies crucial for sustainable water management, contributing to reduced environmental impact.

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.
