Frequently asked questions

Questions related to dewatering containers

  • Does the filter basket needs to be removed or specially protected when emptying (tipping) the container?

    All dewatering containers are emptied by simply tilting.
    The filter basket is securely bolted to the outer container and remains inside.

  • How to choose the right filter cloth?

    We deliver our dewatering containers with filther clothes made of different materials
    (e.g. Polypropylene, nylon, polyamide, polyester, stainless steel). All filter cloths are
    available in a variety of mesh sizes. Tell us your type of sludge and we choose the most
    suitable filter cloth for you. We do not use cheap filter clothes made of geotextile fabrics
    as they assert themselves quickly and have to be changed frequently.

  • Can I change the filter cloth myself and how it is fixed?

    The complete filter cloth is secured with corrosion-resistant perforated stainless steel
    band and stainless steel or plastic screws on the perforated walls of the inner basket.
    In the rare case of a mechanical damage, the customer can replace the filter cloth.
    Necessary spare parts such as filter cloth and mounting material (perforated stainless
    steel bracelet, screws) are available from stock at Kugler.

  • Does the filter cloth has to be cleaned? How is it done?

    The cleaning frequency of the filter cloth highly depends on the type of sludge.
    In case of sludge that tends to get stuck easily, we recommended cleaning after
    several drawdowns. In most cases, cleaning is not necessary, but cleaning is
    advisable after every 5-10 discharge cycles. Cleaning is done by the help of a
    high pressure spray equipment. The Aircon EWC is cleaned through backflushing.

  • Do you have dewatering containers for rental?

    Yes, we provide dewatering containers for testing purposes.

Questions about sedimentation tanks and lamella separators

  • What are the advantages and disadvantages of sedimentation tanks and lamella separators, respectively?

    The clear advantage of round sedimentation tanks compared to lamella separators
    is that sedimentation tanks are not susceptible to clogging. Clogged lamella separators
    need to be cleaned extensively.
    Sedimentation tanks however require a certain relation between tank height and diameter,
    so that a sedimentation tank usually will be higher than a lamella separator. In contrast,
    lamella separators can be build more compact (lower) due their lamella pack which
    facilitates solid-liquid-separation.

  • When should I use round sedimentation tanks?

    If the required height is available.
    If a guaranteed trouble-free and maintenance-free operation is desired.
    In an outdoor installation. The special design prevents freezing.

  • When do I use lamella separators?

    If the required height is not available.
    In confined spaces.
    If the settled sludge does not tend to stick.
