David Sholson of Hydrotek presented a Clean & Green seminar to council representatives and industry leaders on the responsibilities of pressure cleaner operators to comply with EPA regulations.
Australian Pump Industries hosted a hugely successful Clean & Green Seminar presented by David Sholson from Hydro-Tek, US. The reception, held at the Crowne Plaza Norwest, was attended by local government representatives, industry leaders, and specialist cleaning contractors.
David Sholson and Hydro-Tek have lead the way in developing an affordable mobile clean and capture system that enables contractors to comply with the strict U.S. environmental controls. Known here as the Aussie Hydro-loop system, the trailer mounted package contains a robust engine drive steam cleaner and a vacuum recovery system that recovers and re-cycles the waste water.
At the seminar Sholson graphically highlighted the responsibilities of contractors and those using their services to protect the environment. That means following the EPA regulations regarding the discharge of waste water to stormwater drains.
He pointed out the substantial penalties that can be issued to serious offenders and that even accidental breaches can be subject to on-the-spot fines.
Only clean water is permitted to enter the drain. Pollution from cleaning additives, including those that are biodegradable, and materials washed off as a result of the cleaning must be prevented from entering the stormwater drain.
“We have learned from experience that enforcement of EPA regulations makes companies search out affordable, practical solutions,” said David Sholson. “Our Hydro-loop recovery system ticks all the environmental boxes. It cleans effectively using steam with no harmful chemicals required. It recaptures the waste water and filters out the contaminants. And thirdly it recycles the water back to the onboard tank for reuse,” he said.
The system is built around an Aussie Hydrotek steam cleaner, a product already in use with councils around the country. The steam effectively removes graffiti, clean amenities, removes oil stains and chewing gum all without the need for harmful and expensive chemicals. Steam also sanitises and can even be used to kill roadside weeds without harmful chemicals.
Before cleaning, the operator places berms across the entrances of nearby drains forming a natural collection point for the waste water. The scupper attachment of the vacuum system is placed at this collection point. The vacuum unit retrieves the captured, contaminated water and filters it through seven stages before returning it to the holding tank for re-use.
Alternatively the Hydro-loop system can be used with a flat surface cleaner that is directly connected to the vacuum system. Called the ‘hydro-twister’ flat surface cleaner, this collects the waste water with only a little run-off. That run off is collected at the berm dam and can then be vacuumed up at the end of the job.
“Up until now the only option for cleaning contractors has been prohibitively expensive specialist equipment. I was impressed by interest shown at the seminar. There is a real need for this type of system,” said Sholson. “We’ve seen demand rocket in the US as the authorities tighten the enforcement of the EPA regulations and you can bet that this will follow in Australia,” he said.
Australian Pump will be bringing David Sholson back to Australia in 6 months time to host a range of technical seminars on Hydro-loop recovery systems for both distributors and customers.
For those who were unable to attend the seminar, Australian Pump is offering to run demonstrations and information sessions on the Hydro-loop system. Contact Adrian Fiatarone on 02 8865 3500. More information including a video and presentation are also available online (www.aussiepumps.com.au).
