Waterco’s Trimline Bag Filter designed for efficiency and effectiveness

With future trends in water treatment indicating the growing need for new and more energy efficient processes, many operators are seeking solutions to optimise the process.

Waterco’s Trimline Bag Filter has been designed to help address these needs. It offers an economical and user friendly alternative to many liquid filtration applications, and it provides favourable operating cost benefits.

“We have developed this filter to specifically suit the specific needs of water treatment operations,” says Victor Quijada. “It has a higher pressure rating of 6 bar, enabling it to withstand up to 600kPa (87 psi).”

The Trimline Bag Filter is particularly useful for the filtration of high viscosity liquids and liquids with a high level of particulate concentration. The design also makes them ideal as a coarse pre-filter / leaf trapper.

“To ensure we meet the varying requirements of facilities, we employed a one piece mould construction, making the housing of the Trimline Bag Filter out of high impact polypropylene, ensuring it is compatible with a wide range of fluids. In addition, its ergonomic screw down lid is designed for simple hand operation, allowing for a quick filter changeover,” Quijada says.

The filter bags are also disposable, and depending on the intended application, there are different micron rated bags.

Trimline bag filters have been utilised in a vast array of applications from cooling water, aquaculture, koi ponds and water recycling to commercial water filtration.


Waterco launches Hydroxzone Ozonator

Ozone and hydroxyl radicals combine to produce powerful sanitiser

Waterco has launched its new Hydroxzone Ozonator, one of the most powerful sanitisation systems on the market. The Hydroxzone is one of the key components of Waterco’s new Hydroxypure chlorine-free pool system, and it’s designed as a standalone product for both new and existing swimming pools.

“The Hydroxzone Ozonator uses hybrid patented technology to produce not only ozone but also hydroxyl radicals, which, combined, add another level of effectiveness in terms of oxidation and sanitation,” says Victor Quijada, Waterco’s water treatment product manager.

Waterco’s Hydroxzone system uses a modified VUV (high intensity ultraviolet light) ozone tube as a corona electrode to simulate nature (hybrid ozone acts like the sun). The result is an ozone generator that produces ozone using corona discharge technology and high energy light in one system.

“The combination also catalyses Advanced Oxidation Processes (AOPs) and, as a result, hydroxyl radicals are generated,” Quijada explains. “Put simply, hydroxyl radicals are typically formed when UV rays break up ozone and water droplets and then recombine. Scientists have dubbed hydroxyl radicals as the ‘detergent of the atmosphere.’”

The main benefit of the system is an additional ‘layer’ of sanitisation, Quijada says.

“Ozone, which is found in nature, kills microorganisms, destroys organics and breaks down chloramines by oxidation. It’s highly effective in reducing and destroying chloramines in the water

“In addition, ozone provides micro-flocculation to aid filtration and noticeably improve water clarity. It also destroys biofilm and reduces the amount of chlorine consumption while maintaining Free Available Chlorine (FAC) residual.”

Wateco’s Hydroxzone Ozonator can be used in pools with manual or automatic chlorine dosing and also with salt chlorinators.

“The ozone will contribute to the sanitisation process by reducing the chlorine demand,” Quijada explains. “In some states – e.g. South Australia – pool owners ask for installation of an ozonator to run their pool at lower chlorine levels, with the peace of mind that their pool is safe.”

There are a number of key benefits of the Hydroxone system:

  • It produces pure ozone (there are no toxic nitrous compounds as found in standard corona discharge ozone generators)
  • Output is constant and not negatively affected by temperature or humidity as with standard corona discharge technology
  • It produces hydroxyl radical, one of the most powerful oxidisers found in nature
  • There are no moving parts, which makes maintenance easy
  • It’s easy to install and comes with a bypass kit
  • Can be used on new pools or easily retrofitted to existing pools

The Hydroxzone uses a Dynamic Venturi Injector, whereby the pool water is mixed with the ozone/air mix at the throat of the injector through a narrow annular orifice, thus creating very small bubbles. This method of delivery allows the bubbles to be sustained in the water, maximising the efficiency of the ozone mass transfer.

Key features of the Dynamic Venturi Injector include:

  • ASME injector flow configuration to minimise pressure drop
  • Built in restriction at the orifice to increase the injection velocity and maintain constant frothing ratio
  • Adjustable 360°annular injection orifice
  • Dual injector point
  • Internal premixes cavity for dual ports
  • Rugged construction

MultiCyclone Pro

MultiCyclone continues to set the bar high

New MultiCyclone PRO created for commercial installations

Since its launch in 2008, Waterco’s MultiCyclone pre-filtration device has won numerous awards and been used in myriad commercial and domestic installations around the world. But Waterco hasn’t rested on its laurels; it has continued to further develop the MultiCyclone to suit different applications and industries.

One of the latest iterations is the MultiCyclone PRO, designed specifically for commercial applications which require higher pressure rating, such as the water treatment sector.

“We’re constantly undertaking research and development of the MultiCyclone to suit different sectors and uses – both commercial and domestic,” says Victor Quijada. “These include car wash facilities, cooling towers, aquaculture, commercial/industrial water reclamation, filtration and water recycling.

“The MultiCyclone Pro has been created with to cater for a large range of pressure requirements. It has an outstanding pressure rating of 690kPa (100 PSI).”

The MultiCyclone PRO features 16 multiple hydro cyclones and 50mm/2” quick fit unions. It operates by using centrifugal filtration – i.e. incoming water enters the hydro cyclones tangentially, generating a strong centrifugal effect. The process draws the unfiltered water into its spinning chamber, which sends sediment to the wall, leaving clean water in the centre. The filtered water then migrates towards the centre of the hydro cyclone, where the flow reverses and spirals upwards through the outlet.

“One of the key principles is to help save water and minimise filter maintenance,” says Quijada. “It works on the basis of centrifugal water filtration and can cut 80 per cent of the dirt that clogs a filter. Plus it potentially eliminates filter media backwash by up to 40 per cent, which extends the life of a media filter. The added benefits are that there are no moving parts and no filter media to clean or replace.”

Designed for both new and existing installations, the MultiCyclone Pro is also UV and corrosion proof. It’s manufactured from glass filled reinforced thermoplastic, with a clear poly carbonate sediment chamber, which enables the accumulation of sediment to be visibly monitored. Other features include a lock ring and a 25mm/1” sediment purge valve.

Another major benefit of the system is that it’s easily cleaned by opening the purge valve. And only 15 litres of water is discharged to cleanse the MultiCyclone.

Hydrostorm ECO-V 150

Power and energy conservation combined

New Hydrostorm ECO-V 150 packs a punch

Swimming pool energy efficiency is now being factored into swimming pool installations – both new build and retrospective – and a key focus is on variable speed pumps.

In the US Department of Energy’s Measure Guideline: Replacing Single-Speed Pool Pumps with Variable Speed Pumps for Energy Savings, it explains that variable speed pumps are preferable to single speed pumps. “A variable-speed pool pump will allow the homeowner to achieve the ideal filtration flow rate with the least amount of energy consumption. [They] are noticeably quieter, require less maintenance, last longer and, through slower water filtration rates allow for better and more effective filtration of the pool water.”

Waterco’s next generation Hydrostorm ECO-V 150 pump has been designed with the needs of modern day swimming pools firmly in mind – and that translates into plenty of power.

It’s impossible to deny the benefits of variable speed technology – they provide the great opportunity for energy savings. In the case of the Hydrostorm ECO-V 150, it uses over 80 per cent less electricity than a regular pool pump.

What also stands out about this pump is its innovative variable speed, permanent magnet, brushless DC motor. It means the speed control ranges from 1000 to 2850 RPM, plus it offers the finest adjustment in operating speed.

“It gives you the ability to fine tune the pump’s motor speed with 25 RPM increments, allowing a perfect match to the flow requirements of the swimming pool, maximising energy savings and minimising pump noise,” says George Flory, Waterco’s domestic water care product manager.

The Hydrostorm ECO-V 150 can be set to three different pre-programmed speeds to achieve optimal performance:

  • High speed: gives the power needed for vacuuming and backwashing
  • Medium speed: perfect for suction pool cleaners
  • ECO speed: low energy saving speed for everyday filtration. This is the setting pool owners will use 99 percent of the time

“Operating a pump at a low flow rate both reduces water flow resistance in pool equipment and plumbing and also has the added benefit of improving a pool’s filtration efficiency, thus enhancing the clarity of the swimming pool water,” says George.

“And it can potentially operate at speeds lower than conventional multispeed pumps, further improving both energy savings and noise reduction.”

In addition, for those who want to operate their pool equipment automatically, there is an optional communications cable for connection to the Aquamaster pool controller.

And unlike single speed pumps, which in many areas can’t be used at night because of the noise levels, the Hydrostorm ECO-V 150 is one of the quietest pumps on the market, operating at just 55 decibels.

The Hydrostorm ECO-V is also weather proof, corrosion resistant and incorporates a motor protection bracket.This protection bracket fits between the pump wet end and the motor, allowing the draining of any water leaks due to long term usage wear of the main mechanical seal, thus protecting the pump motor from corrosion and eventual failure from a leaking mechanical seal.

A fantstic achievement, for Waterco

International swimming pool and water treatment specialist Waterco Ltd has been granted the European patent for its multi award-winning MultiCyclone system. The revolutionary centrifugal pre-filtration system has also been submitted for a worldwide patent which encompasses the United States, Australia and China.

Managing Director of Waterco Europe, Tony Fisher, calls the granting of the patent “a fantastic achievement.”

“Since its launch four years ago, the MultiCyclone has continued to grow in popularity – and the types of industries which are using the system have continued to diversify,” Fisher says. “The MultiCyclone is now being used in both the domestic and commercial markets, and by swimming pool, water treatment and aquaculture industries.

“And with hotel and leisure chains being put under growing pressure by local government authorities to install environmentally-friendly products which help reduce running costs and conserve water, the commercial use of the MultiCyclone continues to grow in popularity.”

In addition to its water saving benefits, the MultiCyclone is popular for the fact that it reduces filter maintenance. “This is a system which works extremely well,” comments Tony. “It’s easy to install, with no moving parts or media to clean and replace – plus it’s virtually maintenance free.  In developing the unique MultiCyclone system, Waterco has set the bar high – and created a unique category.”

“That’s why the granting of the European patent is so important,” says Fisher. “It protects an innovation as unique as the MultiCyclone, which has such a broad range of uses. Nothing has been more revolutionary in the swimming pool filtration market since it was introduced.”

Over the past four years, Waterco has continued to innovate and invest in different versions of the MultiCyclone. In 2010 it released the MultiCyclone Plus and in 2011 the MultiCyclone Ultra, a compact all-in-one pre-filtration / filtration system which can be mounted on top of a pool pump.

Additionally, high pressure-rated units have been developed for the water treatment market, and a large commercial-sized MultiCyclone is being developed for commercial swimming pools.

“We won’t be resting on our laurels, and will continue to evolve the MultiCyclone to suit the myriad markets which are using this ground-breaking system,” Fisher adds.
