The basic technology behind membrane filtration involves using a semi-permeable membrane to separate a liquid into two distinct streams.

The minuscule pores of Alfa Laval RO membranes only allow small fractions of salts to pass through along with the water, the prime component of the permeate. Certain organic compounds with low molecular weights may also pass through but only to a limited extent. However, the membrane will retain for any other components (salts, sugars, etc.) suspended or dissolved within the liquid flow.

Innovative formulations are used in small quantities to break down algae/cyano into inoffensive and non-toxic by-products such as O2 and H2O

All membrane materials used for both flat sheet and spiral wound configurations comply with EU Regulation (EC) 1935/2004, EU Regulation 10/2011, EU Regulation (EC) 2023/2006 and FDA regulations (CFR) Title 21, and are suitable for use in food and pharmaceutical processing applications. Compliance also extends to the related equipment and fittings, including items such as plate-and-frame units, element housings and pumps.

This version has a pHt™ spiral membrane that tolerates temperatures and pH higher than the RO PE series. The RO98 pHt™ has a NaCl rejection of ≥ 98%.

The Lake Guard® Blue treatment was applied to a 6-hectare reservoir in Israel. While it only took minutes to apply the formula, far-reaching results were evident within 24 hours.

A combination of in-situ measurements, advanced remote sensing capabilities, and satellite imagery allows us to fully understand the size, scale, spread, and location of each bloom.

A water separator removes water droplets in compressed air in three stages; directional change, velocity change & centrifugal separation.

A spiral membrane comprises of a number of membrane 'envelopes' with 2 membrane sheets separated by a permeate spacer mesh, each glued to a central permeate collection tube.

The comprehensive range of ultrafiltration spiral membranes from Alfa Laval is a popular choice for many processes applied in the food, beverage, dairy, biotech and pharmaceutical industries

BlueGreen is honored to have received a “Breakthrough Technology Company of the Year” award at the Global Water Awards (GWI) 2021. BlueGreen was selected from a range of early-stage technology companies for its achievements in treating cyanobacterial proliferations in water bodies of any shape or size. The award recognizes how BlueGreen’s patented formulations are transforming the way cyanobacterial attacks are treated globally as well as the company’s pioneering usage of advanced technologies to monitor, treat and rehabilitate infected waters

Headquartered in Israel, we are a global company with direct representation in the USA, South Africa and China and are planning to rapidly expand our global footprint.

Pumping this liquid across the surface of the membrane creates a positive trans-membrane pressure that allows any components smaller than the porosity of the membrane to pass through, forming the permeate.

South Africa knows more than most countries how critical every drop of water is. Within just a few days, one treatment with BlueGreen’s Lake Guard® solution made billions of gallons of water in South Africa safe for human consumption.

Most people know that climate change, pollution, overuse, and waste is rapidly diminishing the planet’s water supply but there is another deadly problem hiding in plain sight.Cyanobacteria/blue-green algae, or harmful algal blooms (HABS) are proliferating in lakes and oceans around the world where they swiftly dominate ecosystems killing off other organisms, hampering the delicate balance of life in the environment, and causing devastating economic damage to industries that rely on water.Even more frightening, they release harmful toxins (such as cyanotoxins) that can sicken, or even kill humans and animals.

Nan Hu is the beating heart of Yo Yang City and the site of its famous annual water festival. A proliferation of toxic algal blooms threatened to destroy the delicate environmental balance in and around the lake. After exhausting every alternative, government officials appointed BlueGreen water technologies to tackle the problems. Within 24 hours of implementing BlueGreens Lake Guard® technology, the lake’s outstanding recovery was clearly visible on satellite images.

10 Nov 2015 — Establishing a hot water reset schedule allows the boiler to only heat the water to a designated set-point. This can be done several ways.

Any components larger than the pore size simply cannot pass through, and remain behind in what is called the retentate. The surface of the membrane is kept free of blockages by the force of the liquid flow moving parallel to the membrane surface.

Alfa Laval offers nanofiltration membranes for high-yield concentration and demineralization of products such as antibiotics, whey, and beverage production. Learn more.

Alfa Laval reverse osmosis spiral membranes (RO) are low energy, proven solutions for concentrating feed streams, particularly heat sensitive products. The RO spiral membranes can also be used for pre-concentration prior to evaporation as well as product and water recovery from permeate streams and evaporator condensate. The two series of RO membranes have different NaCl rejection properties. The RO membranes are thin-film composite cast on either polyester or polypropylene backing paper.

BlueGreen’s revolutionary technologies and water treatment formulations are responsible for the removal of hundreds of thousands of tons of harmful carbon from our atmosphere each year. By focusing on oceans – the largest source of excess carbon in the world – we are unlocking a massive and untapped potential to clean up the environment and literally preserve life on earth.Our treatments result in the best kind of carbon removal where carbon is transformed into inert limestone. This generates the most desired type of carbon credits in the world.

Lake Guard products are coated with our patented IP formulation making them buoyant by wind or current to the affected location
