The new SMax from CDE Global is the latest addition to the company’s product offering through their CDEnviro division. CDEnviro offer a range of products to the sewage and waste water treatment sectors with a focus on improving screening efficiencies and reducing waste volumes.

The SMax 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, Commercial Manager for CDEnviro. “The SMax 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 SMax 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 SMax sludge screen are as a result of a variety of design features according to CDEnviro. 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 SMax SRU25 has a screening capacity of 250 cubic metres per hour which is a significant increase on other sludge screens on the market.

According to CDE one of the major benefits of the SMax 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 prior to an SMax installation. 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 SMax system to be introduced. “Coupled with the increased efficiency of the SMax 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.”

Following the successful introduction of the SMax to the UK market CDE is looking at opportunities to expand into Europe and further afield. “The SMax is a product with applications on a global scale” explains Matt Bunting. “Over the coming months we will be making significant efforts to secure new markets for this product and the success we have enjoyed to date in the UK will greatly assist this process.” CDEnviro is currently looking for distributors for their range of products for the sewage and waste water treatment sectors throughout the world.
