Aeration expert Suprafilt has landed a £100,000 contract for Scottish Water, the second in 3 months.

The North West based firm has recently been commissioned by Scottish Water’s framework contractor, George Leslie, to supply and install a complete system including new blowers, pipework, valves and instrumentation at the Drongan Wastewater Treatment Works in Ayrshire.

The company will be replacing the existing aeration system with 188 disc diffusers, DO probes, MLS probes and temperature sensors and the project will be completed by March 2013.

Graeme Feilden, Sales Director at Suprafilt, says: It’s great to be working with Scottish Waters again.

“Installing a completely new system is always the preferred method, not only does this work out cheaper but it’s a more seamless process.”

Lee Dempsey, Design Co-ordinator at George Leslie, says: “Suprafilt was one of the recommended tenders by Scottish Water, offering the best value for money. Although we are in the early stages of installation, we have been very happy with Suprafilt thus far and look forward to continuing a great working relationship in the future.”


A Rochdale aeration company has been appointed to fully refurbish Upper Brighouse Wastewater Treatment Works.

Suprafilt, who are based in Rochdale, has recently been commissioned by Yorkshire Water’s framework contractor, Byzack, to refurb the existing systems at Upper Brighouse Wastewater Treatment Works in Kirklees with replacement aeration grids.  They will be using AF D270 disc diffusers, which will be mounted on environmentally friendly polypropylene pipework.

Jonathan Lord, at Suprafilt, says: “Upper Brighouse is a pretty straightforward replacement project. We’ve chosen the disc diffusers mounted on environmentally friendly polypropylene pipework to offer a high efficiency (up to 24gO2/N3/hr/m (8% / m water depth), a low pressure drop, long lasting durability and a quick robust connection.”

Mark Vernon, site manager and commissioning engineer at Brighouse, says: “I have found all my dealings with Suprafilt to be excellent; from the management of the project behind the scenes to site level a pleasure to work with, I wish all our contractors where like them and wouldn’t hesitate in using them again.”



An innovative Rochdale aeration company has scooped a prestigious business award.

Suprafilt, which is based on Albion Road Industrial Estate, won ‘Business of the Year at the Rochdale Business Awards 2012.

The company has tripled turnover in the last 12months and works with some of the UK’s major water companies and leading industrial organisations, such as Seven Trent Water, Thames Water and Diageo.  It specialises in aeration technology, designs and manufactures energy efficient fine bubble diffused aeration solutions, and a range of stainless steel products including pipework and pressure vessels.

Graeme Fielden, Sales Director at Suprafilt, says:  “We’re over the moon to be recognised as Business of the Year in our category. We’ve grown over 200 per cent in the last year alone, despite a recession, which is testament to the passion and commitment of our entire team.

“It’s a very exciting time for Suprafilt, we’re currently the UK’s market leader in supplying ‘Liftable Aeration Systems’ and we’re also the only company in the UK to offer Teflon PTFE coated and fEPDM membranes, which offer double the lifetime guarantee of competitor products and deliver long term energy savings.

“We have also increased our exports five fold on previous years and now supply pipework to Saudi Arabia, Algeria and South America.”

Suprafilt has saved water company Seven Trent Water over 30% of its energy with its innovative diffuser system.

Rochdale-based Suprafilt was brought on board by Nomenca Ltd to find a cost effective solution to upgrade the diffusers at the Ilkeston water treatment plant 18 months ago.

The company, who are market leaders in designing and manufacturing of energy efficient fine bubble diffused aeration solutions, designed a high efficiency system based around MF 1100 plate diffusers, which when installed have reduced the energy consumption of the plant by 30% – saving them £30,000 per year.

Jonathan Lord, Contracts Director at Suprafilt, says: “We originally installed the diffusers at the Ilkeston plant 15 years ago, so it was nice to work here again.

“Our original brief was to look at the various options available to upgrade the existing diffusers to membranes in three lanes, whilst looking at the process optimisation and energy savings.

“In the end we decided on the MF 1100 plate diffusers, which offered Seven Trent Water a high efficiency system and lowest whole-life cost. This is based around an 8% per metre SOTE (standard O2 transfer efficiency).

“Over the year we’ve calculated over £30,000 in energy savings, since the new aeration system’s installation.

“It’s been great working with Nomenca – we have a strong and honest working relationship and the engineers we worked with were first class.   We’re hopeful in carrying on our association with Ilkeston.”

Ian Clarke, Site Manager at NMCNomenca Ltd, says: “It’s been great to work with Suprafilt – their site team in particular were very good.

“All aspects of the site install were exactly on schedule or in some cases ahead of the programme dates.  We wouldn’t hesitate in working with them again.”

Aeration expert Suprafilt has landed a £100,000 fabrication contract for Severn Trent Water.

The North West based firm has recently been commissioned by Severn Trent’s framework contractor, MWH Global, to supply and install 304 stainless steel pipework at the Clipstone Water Treatment Works in Nottingham.

The company will be fabricating the 304 stainless steel pipework which will be attached to the Granular Activated Carbon filters at the site.

The project is started in October and will take eight weeks, which includes three weeks of installation.

Jonathan Lord, at Suprafilt, says: It’s great to be working with MWH Global and the Clipstone site.

“Not many of our clients know that we also fabricate and install full piping systems.  Our engineers are experts in design and fabrication and not only do we manufacture all stainless steel piping on site in Lancashire but we also carryout installation with our own installation teams.”

Paul Wolstencroft, Senior Mechanical Design Engineer at MWH Global, Severn Trent’s framework contractor, says: “I have found Suprafilt to have a very professional approach.  Not only did they work within the timescales provided, but I was particularly impressed by the attention to detail, especially the quality of the site survey they performed.”


Safety first for Suprafilt

Suprafilt has scooped a leading edge safety accreditation from SAFEcontractor – a programme that recognises the highest standards of health and safety practise amongst UK contractors.

Hannah Nolan, Operations Manager at Suprafilt, says: “Here at Suprafilt we are unreservedly committed to achieving the highest practical standards of health and safety.

“SAFEcontractor shows our clients that we have in place the policies and procedures that are required to work safely on sites as well as the monitoring systems in place that ensure we are proactively checking our health and safety performance and looking for ways to continuously improve.

“This accreditation will set us apart from our competitors as well as enhance our credibility both with existing and new customers.”

John Kinge, Head of Risk at SAFEcontractor says: “Major organisations can no longer run the risk of employing contractors who are not able to prove that they have sound health and safety policies.

“More companies need to understand the importance of adopting good risk management in the way that Suprafilt has done. The firm?s high standard has set an example, which hopefully will be followed by other companies within the sector.”

Under the SAFEcontractor system, businesses undergo a vetting process, which examines health and safety procedures and their track record for safe practice. Those companies meeting the high standard are included on a database, which is accessible to registered users only via a website,

Rochdale based Suprafilt Ltd, beat off international competition to win the pipework supply contract for SSI’s aeration system contracts for Yanbu and Jubail Wastewater Treatment Plants in Saudi Arabia. SETE Energy Saudia has now completed installation of the system pictured below. Suprafilt and Stamford Scientific International worked together, drawing on our significant experience working in the middle east, to select the right materials for the project. The picture shows SSI’s AFD350 disc diffusers with fEPDM membranes mounted on Polypropylene header pipes with stainless steel dropper pipes and manifolds manufactured by Suprafilt. SSI’s fluorinated membranes are designed to extend the lifetime of the diffuser and to reduce the frequency of cleaning.
