Disinfecting rainwater
Davey Water Products has launched its Aquashield™ Max automatic water treatment package
for the pressure boosting and disinfection of rainwater, especially where conserved and stored
rainwater is desired to be used as a potable drinking water supply.
The treatment is ideal for applications in domestic households, commercial toilet flushing, public buildings, and any situation where there is a need to ensure that rainwater is safe for drinking and free of contaminants.
The Aquashield Max is also suitable for bacteria and algal control for aquaculture projects or water features as well as treating bore or surface water supply sources.
The system works in a three stage process to treat micro-organisms such as viruses, bacteria and parasitic cysts. These stages include 20 micron to 1 micron filtration, UV disinfection using two Filterpure cartridge filtration stages, and exposure to UV light at 254 nanometers in a Steriflo UV chamber which damages the DNA of contaminants. Davey says the Aquashield unit is able to deliver treated water at flows of up to 70 litres/min and pressures of up to 850 kPa.

Piping system’s mechanical joint handles corrosive waste streamGF Piping Systems has re-designed its mechanical joint for its Fuseal® corrosive waste piping system. The new joint features an EPDM ‘O’ ring seal that accommodates system expansion and contraction as well as temperatures up to 210°F. GF says the chemical and physical properties of the Fuseal piping system are ideal for handling corrosive waste streams.
The piping system is resistant to the corrosive action of alkalis, alcohols, acids, solvents and salt solutions and waste streams which rapidly degrade metallic pipe, (such as dilute mineral acids and aqueous acid salts) have no affect on the Fuseal system. The company says the equipment will not rust, pit, scale, corrode or be affected by electrolysis. The joint is suitable for use in chemical and
industrial plants, and hospital and university laboratories where mixtures of acids, bases, and solvents are drained. The
3 inch and 4 inch fittings have been streamlined for shorter lay lengths allowing the fittings to be installed in tighter spaces.
Gary Sample, GF Piping Systems product manager commented: “The component kits and smaller lay length fittings improves the ease of installation. The new seal design has allowed us to remove restrictions on placing the product in inaccessible locations and close to high temperature waste dumps.”

Wastewater pumps for irrigation and drainageBiral has developed a range of SW wastewater pumps for stationary or portable application. SW pumps are ideally suited for irrigation and drainage functions with clean or dirty water, even if contaminated with abrasive sand or sludge.
Flow of the medium delivered around the motor ensures sufficient cooling and protects the motor from overheating, even with extremely low water level (slurp operation). SW pumps are available as automatic alternating current pumps with level controller fitted, high performance three-phase pumps in combination with a control unit and alternating current pumps for salvage work. The company also offers HP-E and the HPC-E Vertical high-pressure pumps. The HP-E range is for the transportation of drinking water, and the HPC-E range, for the transportation of aggressive media, such as demineralisedwater. These compact pumps come with an integrated frequency converter designed to save energy during operation through the use of variable pressures and water volumes.www.biral.ch
Slimline water tank wins awardReln Pty Ltd, designer and manufacturer of plastic products for the water and agricultural industry, has received and award at the 2008 Western Sydney Industry Awards for its Slimline 2100 water tank, a design that is light, strong, and recyclable.
The tank is 2250 mm long and 820 mm wide, with a 2100 litre capacity. Features of the tank include lockdown feet, a leaf strainer with stainless steel mosquito mesh, an overflow elbow, a 1 inch outlet and tap and is sealed to prevent the entry of vermin and insects.
