• Whale Tankers has developed a dirty water recycling option for its jetvac and jetting vehicles which is said to allow more work between clean water refills.
For jetter use Aqua-Batic removes then recycles most of the water from retrieved sludge in its load compartment. The system comprises three automatic selfcleaning processes: a wedge wire screen that is continuously scoured by compressed air; a cyclone filter; and a fine stainless steel screen.
Another innovation is the hydraulically traversing, selfaligning hose mounted on the rear door. This moves sideways via a rack-and-pinion arrangement to improve access to awkwardly placed sewers.
The Aqua-Batic and rear traversing options are among several new features on Whale's latest 13,000-litre MegaWhale demonstration unit which was displayed at last week's Wasteman '93 exhibition.
The unit is based on a Mercedes 2422 6x4 chassis. With moving division, 125mm extending gully arm, high powered jetting pump and radio controls, it costs around £135,000.Whale has also developed a smaller vanbased jetter, the Jetvan, which can generate up to 320bar for clearing out drains and sewers up to 450mm diameter.
