As a contractor, the nature and location of the projects Andidrain Ltd is involved in can be wide-ranging. Therefore, in order to be able to provide a comprehensive service for its customers a compact and portable solution was required. In addition, Andidrain sought a solution that could be applied to tank cleanout operations to help its customers to remove rag and grit from their tanks as these materials impact capacity, efficiency and are highly abrasive, resulting in wear on downstream processes.


Material on D:MAX screen


CDE proposed its latest product innovation for the wastewater treatment industry, the MSU:10G. A compact, multi-purpose solution, it can be applied to a variety of applications, including tank cleanout operations, gully waste and interceptor cleanouts, mobile decanter protection, backup and emergency screening, and drilling muds dewatering.

It is highly effective at grit and sand recovery, operating at 15 l/s at 6% dry solids screening at 6mm oversize. Recovered grit and sand is diverted from landfill, recycled and reused or sold for revenue gain. The MSU:10G enables contractors to significantly reduce disposal costs while its energy efficiency ensures it operates at maximum performance with a greatly reduced carbon footprint.

The small but mighty solution is also portable, meaning it can be transported between sites to process material closer to the source and eliminating the need to transport waste at high cost to a central processing facility. There then follows a two-stage process consisting of twin EvoWash™ wet processing units with bespoke 10” hydro cyclone clusters, separated by a scrubbing stage using CDE’s ShearClean™ attrition cell technology. The first cyclone clusters perform a cut of 400 Mesh to eliminate contaminants. After attrition, the second stage Evowash™ then performs a further 400 Mesh cut and dewaters to approximately 10% moisture before being stockpiled via a radial stacking conveyor.


Recovered grit from D:MAX solution at Andidrain


Andidrain’s new MSU:10G solution is currently being utilised for tank cleanout operations, processing 15 litres per second to remove rag, grit and other waste materials including plastics. A fully mobile and versatile solution, it can easily be relocated to where it is required or utilised as a fixed installation to provide protection to downstream assets. Recovered rag material is being dewatered to minimise waste-to-landfill volumes and disposal costs while sand and grit is being recovered and used for pipe bedding, landscaping and road base.

“Being a contractor, we have to work within the confines of the customer’s site, so introducing a compact solution to our fleet provides us with the technology to be able to say yes to any project. The compact nature and mobility of the MSU:10G…means we can now take on projects of all sizes and in any location.”
