FILTERS & FILTER MEDIA
Longer lasting, easier to maintain and more effective than sand, Golden Coast believe
glass is the ‘smart choice’ for filter media
WATERCO’S GLASS FILTER MEDIA OFFERS CLEAR ADVANTAGES OVER SAND
Sand has a long history as the filter media of choice. Relatively economical, it is globally popular with pool owners, however, Golden Coast warns that it presents false economy. Managing Director Jamie Adams explained: “While sand and gravel provide effective filtration, there are a number of shortcomings. It is prone to clumping and calcifying over time – allowing channels to form enabling dirty water to pass through. “What’s more, it breaks down over time. The filter particles’ coarse, dirt-catching edges become smooth, lowering filtration efficiency. As a result, the system must be run more regularly, and more chemicals must be added to achieve the same level of water sanitation.” To avoid more work and minimise maintenance costs, it is recommended that media should be replaced at least every five years.

While Golden Coast offers a comprehensive range of filter media, Jamie said glass is the ‘smart choice’. He explained: “It is longer lasting, easier to maintain, and more effective than sand. It may cost more initially, but offers superior long-term value.” Waterco Glass earls, touted as the next generation of superior water filter, don’t degrade, clump, or calcify. They are manufactured from 100% virgin glass, and offer much finer filtration than available alternatives – below 3 microns – resulting in outstanding water purity and clarity. Safe to handle and service, Waterco’s ass earls are installed quickly and easily. A high purity level means that very little backwashing is required to cleanse the filter media prior to start up and cleaning requires 20% less water during backwash than traditional sand.
P At roughly half the cost per kilo, Waterco’s EcoPure Glass Media offers a
cost-effective alternative to virgin glass. Benefitting from the same supreme filtration and water economy as its stablemate, this environmentally-friendly media is not mined, but manufactured from recycled glass.

Jamie continued: “Furthering those green credentials, the superior permeability and cleanliness of ass earls reduces water, chemical, and energy expenditure. With lass, users can maintain a clean environment – both within their pools and the wider world.”

performance down to 4 microns. AFM® (Activated
Filter Media), the company’s Jimmy Lamb TnISPE openly admits that he was just as sceptical as the next man about what ‘Activated’ actually meant. But with an open mind and having taken the time to listen to those who were qualified and experienced, and now having the knowledge and seeing scientific facts behind it, he’s now a convert. A replacement for sand in all filtration applications, Dryden Aqua’s AFM®

manufactured from a specific glass type and processed to obtain the optimum particle size and shape. It is then activated to increase the surface area by 300 times over crushed glass or sand.
is the only activated glass filter media available, and Dryden Aqua say it is more efficient and cost-effective than any other filtration media. AFM®
The high surface area is negatively charged (zeta potential) to adsorb organics and small particles. It also has permanent metal oxide catalysts creating a high redox potential to make the product self-sterilising. AFM®
grade
1 is a direct replacement for sand used in most drinking water gravity flow and pressure filtration systems.
USE CERTIKIN’S EXPERTISE FOR FILTER SELECTION Naturally, Certikin is there to sell products, however the team are also happy to give free technical advice.
Commercial filtration, is a classic case in point where seeking expert help pays dividends. Commercial Manager, Steve Nelson explained: “A successful and efficient commercial filtration system requires accurate velocity and filtration rates to be taken into account. Sizing equipment is what we do every day at Certikin.
has already been extensively tested and compared against a range of filter media by the independent accredited laboratory IFTS in France.
Recent tests conducted by IFTS on grade 0 AFM®
(0.25 to 0.50mm psd) have confirmed a very high performance, >97% removal of all particles above 1 micron and >99.8% above 5 microns. Tests were conducted at a water velocity of 20m/hr with no pre-coagulation or flocculation. AFM®
grade 0 can therefore
remove cryptosporidium and most parasites and large bacteria found in water. Grade 1 (0.4 to 1.0mm psd) almost gave the same
“Our portfolio features an extensive range of commercial filters including the hugely popular SLX and SLX Plus and can tailor make a filtration solution for every pool.” The market leading SLX Plus bobbin wound filter comes complete with side manhole hatch and 3 inch sight glass as standard (on the SLX these features are optional extras). The filter boasts the very latest manufacturing techniques to produce a high quality finish on the bobbin windings. The filter retains all the key benefits of the SLX, such as the flange connections (they are at the same height and size as the SLX) and the highly effective ARV system. These filters come as 2.5 BAR standard but 4 and 6 BAR pressure along with nozzle plate versions or deeper bed depths are also available.
When it comes to domestic swimming pools, Certikin’s exclusive Vision bobbin wound domestic filters are bestsellers in their sector.
