Water disinfection technology and the food and beverage industry

The latest technological innovations supporting water disinfection in the food and beverage industry will be the focus of the Water Academy seminar, jointly organised by Hanovia and Domnick Hunter RL, taking place in Bangkok, Thailand, in September.

The one-day seminar will focus on best practice in process water technologies, and is aimed at process engineers and those responsible for technology procurement.

The seminar is the first in a series to be held across the Asia Pacific region, where the beverage industry is growing rapidly due to increased demand in sectors such as bottled water, carbonated soft drinks, dairy and brewing. Water disinfection and treatment is a key element in the beverage production process globally, and the use of ultraviolet (UV) technology within the industry is predicted to increase by 12.5% over the 2015-2020 period.

Hanovia, a leading provider of UV disinfection technology and water treatment solutions for industrial applications, will be making a series of presentations during the seminar’s morning session.

These will include an introduction to UV light technology; a look at how UV dechlorination can reduce water treatment maintenance and lifecycle costs and provide enhanced protection against bio-contamination; details of how UV technology can be used in applications such as sugar syrup disinfection and process water deozonation; and an explanation of the validation process for UV systems.

The afternoon session will include a presentation by Domnick Hunter RL – Thailand’s leading provider of liquid filters, water treatment and gas generation products – about cartridge filtration in beverage applications.

“This will be an informative and educational seminar, looking at the key water technologies that can benefit the beverage production process,” said Gunvinder Bhogal, Hanovia’s Global Marketing Manager. “The day’s presentations will focus not only on current best practice but also the innovations that will shape future development. It is a fantastic opportunity for attendees to network with leading industry experts and gain important knowledge about the latest technological advancements.”

Australian water filtration tech wins $500k award

UTS scientists have developed a low-cost, easy-to-operate water filtration system to remove arsenic and deliver safe and clean drinking water. The project won a Technology Against Poverty prize of $500,000.

Professor Saravanamuth Vigneswaran and Dr Tien Vinh Nguyen from the University of Technology Sydney (UTS) faculty of engineering and IT received the prize for their project to remove pollutants from groundwater in the Red River Delta of Vietnam. This densely populated area is beset with serious public health issues caused by high levels of arsenic in the groundwater.

Arsenic poisoning is a slow process, with people often unaware they are being poisoned as they suffer major health problems including cancers, gastrointestinal disorders, muscular weakness, nerve tissue injuries, blackfoot disease and intellectual impairment.

Current systems are neither cost-effective nor efficient at removing arsenic. The UTS team is working with Vietnamese partners on a local solution to a local problem in an area of about 20 million people. Partners include the Vietnam National University (VNU), Vietnam Academy of Science and Technology (VAST) and local manufacturers.

The scientists are deploying inexpensive technology to provide a model for clean water, which can be adopted worldwide to improve water quality for more than 130 million people in the 70 plus countries worldwide experiencing toxicity from naturally occurring arsenic.

“There are three key components to this system: an organic membrane, a tank/drum in which the membrane is inserted, and an absorptive cartridge made from locally available industrial waste products,” said Vigneswaran.

Local manufacturers can produce, install and maintain the membranes and the cartridges, creating local jobs in an area of high population growth, according to the scientists.

“The filtration can be powered by gravity or solar or by hand pump. Membranes will last up to three years, while the cartridges absorb the arsenic and are periodically replaced with new ones (every three to six months). The waste cartridges will be turned into safe building materials, so the system safely disposes of arsenic waste,” said Vigneswaran.

The system will also remove bacteria and solids from the contaminated groundwater, delivering water that is clean and safe to drink, and is scalable: for example, a 10-cubic-metre system will provide uncontaminated water for 100 people.

“This sustainable system will both maximise locally sourced resources and minimise arsenic waste and environmental pollution, improving health and quality of life,” said Vigneswaran.

Conductivity meter to measure water quality

The 703 laboratory conductivity meter from Alvi Technologies simplifies the monitoring and measurement of conductivity of water with its numerous safety functions and record printouts.

Alvi’s 703 laboratory conductivity meters are suitable for a broad range of applications requiring water quality monitoring. Key features include measurement ranges from 0.000 µS/cm to 2000 mS/cm; well-designed IP54 rated enclosure; calibrated analogue galvanically isolated recorder output; Sensoface monitoring of sensor and measuring equipment; and an RS 232 interface for the computer and printer.

Conductivity is considered a good indicator of water quality. Conductivity of water is affected by positive or negative charged ions, and has a critical influence on aquatic life since every organism has a typical tolerance range. Measuring the conductivity of water could specifically be useful for fisheries.

Salts and other substances affect the quality of water used for drinking. Conductivity readings from the meter could be one of the measures taken into consideration when testing the output of raw water that comes from different water sources to determine the treatment process.

The water from a lake, river, or tap is rarely suitable for industrial use as it contains contaminants, largely ionic, which if not removed will cause scaling and corrosion in plant equipment, particularly in heat exchangers, cooling towers, and boilers. The water needs to be treated before it reaches the equipment. The residual output of a water treatment plant is discharged into oceans or rivers or used in irrigation. Depending upon the application, the water needs to be treated accordingly. Since conductivity is a measure of the total concentration of ions, conductivity measurement is done at different stages of water treatment.

 

Chemical free water treatment cleans up Thai sugarcane processing

COMPUTER-generated frequencies are being charged through wastewater to help sugarcane-processing plants in Thailand meet environmental standards.

Hydrosmart is a South Australian company that uses a unique water treatment process to improve water quality without the addition of chemicals.

Its microprocessors sit on the outside of pipes and send emit frequency shots to disrupt the bonds of minerals in the water, dissolving calcium, iron and gypsum scale off pipes.

It is now being used to reduce algae and improve the chemical oxygen demand (COD) of sugarcane wastewater in the eastern Thai province of Sakeo.

Managing Director Paul Pearce said the onflow from sugarcane wastewater was a serious environmental threat where large amounts of harmful materials were carried into waterways.

“Thailand has certain regulations as to what they can put out to the environment and COD is one of those they have to get to a certain level of,” he said.

“Our unit allows for the microbes and bacteria to thrive, the beneficial ones, and balance the water to a healthier state by reducing particle size, without the addition of other things.

“After installing the smaller D60EO model, the changes it has made to the quality of the water have been quite significant and it has even helped to remove odours.”

The sugarcane project was initially run as a trial using a smaller waste pond to test the effectiveness of Hydrosmart’s U-bend technology.

The D60EO model used in the trial consists of a 60mm PVC pipe that connects to the pipes that pump water out of the wastewater pond (pictured below).

Using two sets of frequencies, the economy unit was able to successfully treat the water within four weeks of being installed.

The plant now plans to install a full-sized model at its primary waste pond in Thailand.

According to Statista, Thailand exported 7.8 million metric tonnes of sugar in the 2015-2016 financial year. That figure is expected to rise to 8 million metric tonnes this year.

Pearce said the microprocessor unit was highly efficient and would only use about AU$10 a year worth of electricity in most cases, less than a standard light bulb.

He said the device required little maintenance and would work year-round as long as it remained plugged in and activated.

Hydrosmart’s technology is also being applied to textile wastewater in Bangladesh and is improving water quality in the Polynesian sovereign state of Tonga.

South Australia is the driest state in the driest continent in the world and has become a world leader in water treatment and reuse technologies.

Water Industry Alliance CEO Rachel Barratt said non-chemical wastewater treatment technologies were becoming an increasingly important element to meeting international environmental standards.

“Sugar cane as an industry internationally is mammoth now and the expectations about its pollution and run off is becoming more stringent,” she said.

“The processing of sugarcane contains a lot of organic matter and heavy metals so it’s great to see Hydrosmart doing so well internationally and using their solutions to tackle global challenges that have a direct and real impact on other communities.”
