EWC-Lamella

The compact system for water clarification and sludge drying.

Kugler now provides a new patented solution combining a lamella pack and drainage container in one unit, the lamella drainage container LAMELLA. Now it is possible to operate our dewatering containers in a continuous flow.

Advantages at a glance

• Continuous operation
• Supply or disposal of treated process water
• Low investment as well as minimal operating and maintenance costs
• small space requirement
• Compact unit: Collection, purifying, dewatering, drying, storing and transport in one container
• Low susceptibility to failure
• For up to 30 m³/h of wastewater
• Available in sizes from 3 to 40 m³
• Easy installation and start up: Only connect the inlet and outlet – done!

Functional principle of systems with EWC lamella

The EWC LAMELLA looks from outside like one of our „standard” dewatering containers (EWC): A standardized skip or roll-off container. Besides the filter basket (frame, perforated plates, filter cloth) however, inside you find a coarse filter, baffles and a pack of lamella strainers.

From the collection pit, wastewater is directly pumped to first compartment of the EWC LAMELLA. Already in this stage larger solids settle down. Then the pre-treated wastewater then passes through baffles to the lamella strainers, where a coarse filter removes remaining bigger floating particles. Due to the low flow velocity, the smallest fraction of particles settles on the lamellas and slides continuously down to the back compartment of the container and is being drained. Finally, the cleaned effluent passes an overflow and flows to a storage tank.

After stopping the wastewater flow to the container, the settled sludge is dewatered up to the state of being semi-solid. Once the container is full of dewatered sludge, our container can be taken by a corresponding truck to the waste disposal site. There the dry sludge is dumped out of the container. Then the emptied container is transported back to its location in the company and the process cycle starts again.

The EWC Lamella:

• Clarifies the wastewater,
• Collects the wet sludge,
• Dewaters the sludge until it is semi-solid,
• Stores the dewatered sludge
• Keeps the solid material during the transport to the disposal site.

Example of plants with the EWC-Lamella

In addition to the EWC-LAMELLA, for a full process water cycle are only needed:

• Wastewater collection pit with sewage pump,
• Clean water tank or basin,
• Booster station for water recirculation, if required.
