Winery wastewater problem solved by ‘internet of things’

Related tags Water

A water-treatment company is using the “internet of things” to command an army of bacteria in the battle against polluted winery wastewater.

South Australian company Factor UTB has developed the web-networked technology to alter the treatment environment for winery, industrial and municipal wastewater. 

Chief executive Rex Gibbs said the monitoring technology allowed the company to target and strengthen the bacteria that clean the water in holding tanks. 

He said native bacteria that attacked organic pollutants and excess nutrients in wastewater were harvested from sewage pipes, winery drains and waste streams. 

Then we train them up like Olympic hopefuls so they do what we want​,” Gibbs said. 

We are achieving nutrient results that are far better than almost anything else that is being produced. We are also able to achieve this at less than a dollar of chemicals per kilolitre treated​.” 

Factor UTB last month received a Water Industry Alliance award for excellence in environmental practice. 

Beyond the wine industry, the company has also built water tanks for Acacia prison in Western Australia, Australia’s biggest prison. 

Factor UTB uses 3G networks to access water tank controls to manipulate the environment. It is also able to control the pumps remotely across large distances. 

Tanks are fitted with sensors to detect pipe leaks, which can send an immediate notification to company personnel. 

The tanks are also fitted with probes and sensors to detect changes in alkalinity or oxygen levels and automatically adjust settings to optimise water treatment. 

The system is able to remove pollutants from millions of litres of water a day. Every litre of wine produced requires about five litres of water for cleaning. 

Gibbs said wastewater from a winery producing about 12.5m litres of wine contained about the same amount of biochemical load as sewage from a town with a population of about 20,000 people. 

The water that comes out of wineries is filthy and has extremely high pollutant loads. We do turn filthy water into dirty water and then we re-treat it to turn it into not very dirty water​,” Gibbs said. 

"We remove about 90% of the pollutants, and then when re-treated we remove 90% of what's left. The treated water can be used for many things without further treatment​. 

You can use the dirty water to water under-wood lots; you can certainly use it to water compost heaps and other things like that to make compost better​. 

The water is best used to irrigate something other than grapes. It's good crop hygiene to use the treated water to irrigate something other than what was originally produced by using that water​. 

The biggest tank we built for a winery is in Marlborough [New Zealand], and is about 1,800sq-m. If an Adelaide home churns through 500 litres a day, the one in New Zealand can churn about a 22,000 house equivalent​.” 

Gibbs said the treated water that was equal or better than the natural water in streams, and allowed the water to be returned to the environment. 

He said Factor UTB was in talks with wineries in South Africa. 

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. 

Gibbs said locating plants in towns and using treated water to irrigate parks and sporting fields could save 30% of the running cost of a traditional out-of-town plant. 

He said Factor UTB’s tanks prevented harmful odours by adding new waste to the bottom of the pre-treatment storage and regularly aerating tanks.
