Brightwork & Fabiton developed the EcoBlue filter

In a joined effort, Brightwork, and Fabiton developed the innovative EcoBlue filter. Together they now launch this new product.

Continuous sand filtration with high capacity

The EcoBlue filter is based on the well-known continuous sand filtration principle. In recent years, there has been a growing demand worldwide for compact and modular (waste)water treatment solutions. The EcoBlue filter is the answer to this need, since it is entirely comprised of prefab components which can be quickly assembled into a working system on site. By combining multiple filter cells into one unit, it is possible to create a high throughput of up to 500 m3/h.

Advantages of the EcoBlue filter

“The advantages are lower construction costs, short construction time, the optimal filter performance, lower carbon footprint and superior construction quality. Our partnership combines Brightwork’s process knowledge with Fabiton’s expertise in prefab concrete construction. It is an excellent match.”, according to Hans Wouters, CEO of Brightwork.

Sand-Cycle

Moreover, the EcoBlue filter is compatible with the Sand-Cycle remote monitoring & control tool. This tool, developed by Brightwork, is based on RFID technology and enables remote monitoring and control to optimize the filter performance, and thus reducing operational costs. Various applications are possible: nutrient removal in wastewater treatment, surface water treatment and process water reuse.

BW Products rapidly provides continuous sand filter in Wales

“Speed is of the essence”, with that motto in mind, BW Products rapidly provides a continuous sand filter in Wales. Within a few weeks this filter installation will be in operation by Welsh Water. In this way, an urgent discharge problem at one of her sewage water treatment plants can be solved completely.

Answer to client requests

“More and more often we get questions from our clients to solve an urgent problems. We then come in to action as soon as possible to adjust existing installations, but also to to supply complete (waste)water treatment installations in a very short timeframe, as in this case”, says Matthias Bosma, Marketing & Sales Engineer bij BW Products.

In recent years, BW Products has invested in expanding her rental fleet of temporary (waste)water treatment installations. By deploying one of the continuous sand filters that is part of the rental fleet, necessary support can be offered immediately.

Continuous sand filter installation with Sand-Cycle

Even before the end of this year, the continuous sand filter installation will be in place and operational at a small sewage water treatment plant in Wales. In this way, the effluent of this plant will be treated additionally so that it meets the strict discharge consent requirements.     The performance of the continuous sand filter will be closely followed by using Sand-Cycle remote monitoring, which is based on RFID technology. RFID tags ared added to the sand filter bed and follow the filter sand’s behaviour.

After registering the tags, the Sand-Cycle tool provides an online dashboard that gives insight in the real-time filter process, depicting for example current sand circulations speeds in an easy to understand graph. Using this tool makes it possible for the operator to see anomalies earlier and act on these accordingly.

Supply & Support

“With this “Supply & Support” we anticipate on a clear need in the market”, says Bosma. “Our clients appreciate our sense of purpose and creativity. Moreover, with our directly available installations we can put our money where our mouth is. Also, for temporay solutions we provide customized treatment solutions”.

Sand-Cycle receives positive feedback in Norwegian pilot research

Sand-cycle receives positive feedback of researchers that have used Sand-Cycle in their pilot testing with continuous sand filtration at WwTW Gardermoen in Norway. They are enthusiastic about the use of this tool and reported their positive feedback.

International Water Association (IWA) publication

The research, executed on behalf of the Regional Research Council of the city of Oslo, focused upon nitrogen en phosphorus removal in a continuous sand filter after MBBR treatment. Very low effluent levels were consistently established; results have been published by IWA in the 80th Volume, Issue 2, of Water Science & Technology (see this link: https://doi.org/10.2166/wst.2019.266 to read the full article).

Robust and easy to use tool

The research team indicated Sand-Cycle to be a very convenient tool for monitoring good operating filter conditions. The results are reliable and, in addition, Sand-Cycle contributed to the quality and intensity of the research. Quick interventions were possible, once Sand-Cycle detected process anomalies, reducing valuable research off-time. These positive experiences with Sand-Cycle confirm what other users already have experienced. Sand-Cycle frequently receives positive feedback from other (inter)national references.

Sand-Cycle dashboard

The Sand-Cycle dashboard below clearly illustrates the recorded distinction between a good and bed performing filter. The scatter between the average and the standard deviation values indicates the homogenity level of the system. Greater spread (thicker band) implies that few parts of the filters flow significantly faster or slower. This case of thick band also depicts relatively lower performance level of the filter.

The figure above is a Sand-Cycle dashboard of the pilot at RWZI Gardermoen on March 1st 2018. The graph shows the average sand circulation speed (blue line) during 48 hours and the related standard deviation (upper and lower gray lines). In this way, this graph gives realtime insight whether the filter is running good or bad.
