New S:Max Sludge Screen launched by CDEnviro

Within the UK Waste water industry CDEnviro has successfully installed numerous high frequency sludge screens to remove rag from thickened sludge. This rag can be removed from either imported sludge (where sludge is transferred from smaller sites for processing using tankers) or indigenous sludge (the sludge that is generated on the same site).

New S:Max Sludge Screen launched by CDEnviro

The S:MAX unit is designed to handle a variety of materials including sewage, digested sludge and imported sludge with the specific aim of reducing screenings content in these materials. "The presence of screenings has a detrimental effect on efficiencies within the treatment process for various sludges” explains Matt Bunting, General Manager for CDEnviro. "The S:MAX sludge screen offers significantly higher capture rates for this material when compared to other sludge screens currently in operation within the sewage and waste water treatment sectors.”

The S:MAX is currently in operation with some of the major water utilities in the UK and is delivering screenings capture rates in excess of 80%. "During the development process for the SMax our research into the existing product offering revealed a standard capture rate of around 30%” says Darren Eastwood, Technical Sales Manager with CDEnviro. "By increasing this to 80% as we have done with our existing SMax installations our customers are enjoying significant efficiency gains within the sludge processing and treatment phase of their operations.”

The increased capture rates being enjoyed as a result of the introduction of the S:MAX sludge screen are as a result of a variety of design features. These include a unique Autowash system, anti-pegging screen media configured to the specific demands of sludge screening and low ongoing operation and maintenance costs and as result of high specification components and a low power requirement. The S:MAX SRU:25 has a screening capacity of 250 cubic metres per hour which is a significant increase on other sludge screens on the market.

One of the major benefits of the S:MAX over existing sludge screens on the market is the capability to discharge material directly onto the screen eliminating the requirement for a reception tank for the material. This reduces the footprint of the plant while also minimising the amount of civils work required to allow the S:MAX system to be introduced. The result of this design feature in particular is that there are significant cost advantages for customers as a result of the reduction in additional site work required to allow for the S:MAX system to be introduced. "Coupled with the increased efficiency of the S:MAX unit, the cost advantages of a new system over others currently on the market mean that we are very confident of securing many more installations in the near future” says Matt Bunting.

Although initially launched to the sewage and waste water treatment sector in the UK the SMax also has application in many other industries according to Marc Jennings, Product Development Manager with CDEnviro. "The SMax can be configured to cope with a wide variety of sludges whether from the food industry, paper and pulp sectors and the pharmaceutical industry among others. Basically any business that is currently processing waste sludges can benefit from the introduction of the SMax system.”
