VSEP Slashes Waste Treatment Costs

Category : VSEP

A/Prof Heitz’s team found VSEP reliably trapped 97 per cent of organic contaminants above the membrane, allowing smaller salts to filter through and produce a concentrated salt solution that is re-used upstream.

SHAKE, rattle and roll has slashed costs and reduced waste volumes at the Wanneroo Groundwater Treatment Plant.

The Wanneroo plant is successfully using a vibrating membrane to separate contaminants from its waste stream, producing a recyclable salt solution in the process.

The innovative system, called vibratory shear-enhanced processing (VSEP), relies on shaking and sideways forces to prevent large particles from blocking the membrane surface.

“Normal membrane treatments would clog up really quickly,” co-author and Curtin University Associate Professor Anna Heitz says.

“With this system, the contaminants aren’t sucked onto the surface of the membrane, there’s always this vibration going, agitating the surface.”

A/Prof Heitz’s team found VSEP reliably trapped 97 per cent of organic contaminants above the membrane, allowing smaller salts to filter through and produce a concentrated salt solution that is re-used upstream.

“Prior to this process, you would just buy new salt,” A/Prof Heitz says.

“Now we’re recycling: we can separate the salt, reuse that salt, we don’t have to throw it away.”

The plant treats up to 50 per cent of its groundwater using beads of magnetic resin to adsorb naturally occurring contaminants, a process called magnetic ion exchange, or MIEX. Once loaded with contaminants, these MIEX beads—manufactured in Australia by Aussie company Ixom—are also recyclable.

“You hit the resin beads with this highly concentrated salt solution, more concentrated than sea water, and the contaminants go into the salt solution, so you can reuse the beads,” A/Prof Heitz says.

By washing the resin beads with salt solution produced using VSEP, the MIEX plant becomes even more efficient, she says.

“This project was about taking waste from cleaning the resin beads—waste which is really difficult to deal with and expensive to dispose of—and further treating it so you can recycle part of it,” A/Prof Heitz says.

“You don’t have as much waste, you save on salt costs, you save on tankerage costs.”

In the first eight months of VSEP operation, the plant cut its salt costs by 38 per cent, recovering 75–85 per cent of the waste stream volume instead of paying for its disposal.

“You’d be able to use this process to clean up waste from other plants, for example water treatment plants in remote parts of Australia, where you can’t discharge brine,” A/Prof Heitz says.

Niagara Bottling Finalises Agreement for VSEP Brine Treatment

Category : Water Treatment

In a recent press release from PR Newswire, New Logic Research have announced the finalisation of an agreement with Niagara Bottling for the supply of VSEP systems as part of a brine minimisation program.  The addition of the VSEP systems will eneable Niagara to further increase water efficiency to greater than 99% plant wide.


VSEP Brine Minimisation systems

VSEP’s patented vibratory shear mechanism coupled with an innovative filter pack design keeps its membranes remain free of obstruction, ensuring trouble-free operation even in the face of difficult feed waters like reverse osmosis (RO) brine.

“We pick up where traditional RO systems leave off, filtering and concentrating the brine past the point where dissolved solids actually drop out of solution—an unthinkable proposition in other membrane systems. It’s this unique ability driving New Logic’s rapid growth in the field—increasing water yield through RO brine minimization,” said New Logic CEO Greg Johnson. “We’re proud to partner with Niagara —a fellow California company dedicated to providing innovative, high quality products for its customers.”

“VSEP is essentially a zero-wastewater purification system that will allow us to bottle 99%+ of the water we draw.  Increasing yield makes sense from both a business and sustainability perspective,” said Niagara CEO Andy Peykoff II. “This system will make our new facility the most water-efficient purified water bottling plant in the U.S.  We’re excited to get the system up and running.”

In recent years, New Logic has successfully commissioned many systems for RO brine minimization at bottling plants and a host of other industrial and municipal facilities around the world. Drivers for this growth include municipal infrastructure limitations, sustainability mandates, water scarcity, and increased regulatory scrutiny of brine discharge.

Hampton Downs Landfill Leachate Treatment Plant

Category : Water Treatment

The Client

The North Waikato Regional Landfill at Hampton Downs is New Zealand’s largest landfill. Situated between Auckland and Hamilton it receives 500,000 Tonnes per annum of municipal waste from Auckland.

Their Issue

The landfill needs to dispose of 150kL to 300kL of leachate each day. This was being transported offsite and discharged into the Auckland sewer 70 km away.

How Much it was Costing Them

To transport and discharge the leachate cost $22 /kL, or between $3,300 – $6,600 a day. The continued tankering of leachate offsite for the landfill’s anticipated life of  35+ years was quite literally throwing atleast a million dollars a year down the drain.

The owner and operator of the landfill, EnviroWaste Services, projected that as the size of the landfill grows this cost will increase by a further one million dollars every five years. By 2020 the transport and treatment costs alone will be $2.5M. Add to this the capital costs of more storage tanks and tanker trucks, price increases by the waste water treatment plant and the ever present risk they could change their acceptance criteria.

What needed to change

The ability to treat and dispose of the leachate onsite was desired. To achieve this the processes considered included:

  • evaporation
  • biological and chemical treatment
  • reverse osmosis

Evaporation was dismissed as nonviable. Evaporation to air is not possible due to Auckland’s average relative humidity in the range of 70% – 85%.

The landfill generates and harvest its own landfill gas, which it uses to generate electricity that it can on-sell. Using this gas to power an evaporator was investigated but the cost in lost revenue from electricity sales would be $38 per kL of leachate treated.

If the leachate is not vaporised and released into the air then any liquid or solid effluent/by-product of the treatment process would need to be disposed of to land or a waterway. Solid or sludge by-products could be returned to the landfill but any liquid effluent that could not be reused on site would need to be irrigated or released into a waterway. Their consent to irrigate to land only permits this when there is a soil moisture deficiency and only allows 150 kL per hectare per three days, and only from October to March. The Waikato River runs just east of the landfill and a consent to discharge into the river was granted, but with strict water quality criteria, particularly regarding Boron and Ammonia, and an allowable conductivity of only 20 μS/cm.

Reverse osmosis was going to be needed in order to achieve the strict environmental consent quality requirements. Traditional spiral wound reverse osmosis membranes would require pre-treatment, using either a biological system or otherwise a series of micro and ultrafiltration membranes, in order to prevent them from fouling and constantly needing cleaning.

The Solution

Alternatively a single pass through a vibrating membrane was proven in a series of pilot tests to adequately clean the leachate without fouling the membrane. The principle behind the vibrating membrane is that the vibration prevents the membrane from fouling.

Syngineering designed and constructed a treatment plant capable of treating 300 kL/day.  The system uses six VSEP systems to reduce the feed water with a Total Dissolved Solids (TDS) of 5,ooo ppm down to 550 ppm.

The permeate from the first stage is then treated through four stages of spiral RO.

Through this process it is possible to achieve a final permeate that is well below the required levels:

  • TDS of 0.1 ppm, down from 5,500 ppm
  • COD of 0.002 mg/L, down form 4,100 mg/L
  • Ammonium of 0.08 mg/L, down from 930 mg/L
  • Boron of 0.18 mg/L, down from 26 mg/L

VSEP used in Brazillian Ethanol Plant

Category : Water Treatment

VSEP from Syngineering Water

While membrane-based separations of liquids from solids have enjoyed increasing popularity over the last twenty years, the technology has an inherent challenge that affects all membrane devices: fouling. This long-term loss in throughput capacity is due primarily to the formation of a boundary layer that builds up naturally on the membranes surface during the filtration process. In addition to cutting down on the flux performance of the membrane, this boundary or gel layer acts as a secondary membrane reducing the native design selectivity of the membrane in use. This inability to handle the buildup of solids has also limited the use of membranes to low-solids feed streams.
