INDUSTRY-LEADING SYSTEM FOR RAG & GRIT RECOVERY

The S:MAX range is specifically designed for automated screening of all types of sewage sludge including:

  • Raw Sludge
  • Surplus Activated Sludge
  • Septic Tank Sludge
  • Digester Feed Sludge and digestate
  • Lagoon / Pond Emptying Solids
  • Storm Screenings
  • Tank Cleanout Residues.

It can easily accommodate both indigenous sludge and imported sludge with a design that enables the capture of rag and grit from even high solids sludges. S:MAX offers significant operational efficiencies as a result of increased screenings removal, elimination of blockages and reduced power and water requirements.

Eliminating blockages during sludge screening 

Blockages within existing sludge screening plants are the single biggest cause of increased operational costs and long periods of plant downtime. A unique back wash system on the S:MAX ensures that the screens do not block with material offering utilities and contractors a significant reduction in the cost of operation and maintenance as well as an increase in plant uptime.

By processing at the fastest rate possible, with no requirement for a reception tank, tanker assets are optimised and transportation costs minimized.

Biomass power generation

Removing the majority of rag and grit before they reach valuable sludge processes, maintains capacity in tanks further down the treatment line for biomass power generation in the anaerobic digestion phase. Companies can maximize the potential for the generation of energy from biosolids by reducing the level of biosolids contamination within the digesters. The benefits of effective screenings removal also include reduced operation and maintenance costs at the anaerobic digestion phase.

THIS IS HOW WE DO IT
EFFECTIVE RAG & GRIT REMOVAL
Grit and rag are dewatered on the S:MAX before being removed as independent outputs. The effective removal of rag through a compactor provides further dewatering.
AUTOMATED BACK WASH
The automated back wash system eliminates the requirement for an operator to be on standby and minimises blockage & routine maintenance.
SAFE MAINTENANCE ACCESS
BS 5395-3 stairs and walkways ensure easy, safe access for inspection.
MULTIPLE INLET POINTS
2-3 Inlet Points for indigenous and tankered sludge.
HIGH EFFICIENCY & THROUGHPUT
CDE’s non-pressurised screening technology ensures high efficiency and high throughput with minimal blockage.

ENGINEERED FOR EFFECTIVE SLUDGE MANAGEMENT

The proven capability of the S:MAX to handle 10% dry solids within the raw sludge makes it the industry-leading choice for operators in the industry.

CDE’s S:MAX is used in variety of industries including wastewater treatment works, sewage treatment works, demolition contractors and wastewater contractors.

The S:MAX operates at less than half the water pressure of other systems on the market, therefore requires less wash water. This allows for the system to be easily retrofitted to existing sites as the S:MAX does not require a high pressure water pump to feed the system. Further benefit is gained from the reduced power requirement of the plant which once again has the dual benefit of reducing costs of operation while ensuring a minimal carbon footprint.

The S:MAX range consists of 4 different products - SRU15, SRU25, SRU15G, SRU25G - each with different capacities to suit your business operations.
