OPS Filtration represents a reliable and user-friendly solution central to waste filtration and de-watering. The OPS range of filtration vessels effectively removes insoluble particulate matter from wastewater through advanced filtration systems including parabolic screens, back-washable and dynamic sand filters, cartridge filter vessels, and media absorption filters. OPS employs a variety of filtration techniques optimized for specific applications. The key parameters for filter sizing are solids loading and flux rate through the filter bed, and it's crucial to consider the water's nature, such as oil content and polyelectrolyte residue. Given the unpredictability of water in many applications OPS deals with, backwashing is necessary for sand and media filters, requiring a constant water supply. When specifications allow, OPS integrates cost-efficient off-the-shelf items to reduce capital expenditure. The integration of high-efficiency processes with best-in-class process control ensures consistent performance, reliability, and optimized life cycle costs for OPS's engineered solutions.

Reliable and easy to use, the OPS range of filtration vessels are central to our waste filtration & de-watering solutions, removing insoluble particulate matter from wastewater using parabolic screens, back-washable + dynamic sand filters, cartridge filter vessels and media absorption filters.

OPS design and utilise many different types of filtration:

  • Parabolic screens as primary screens
  • Back-washable sand filters – duty standby
  • Dynamic sand filters
  • Cartridge filter vessels
  • Back-washable media absorption filters

The key parameter for sizing filters is the solids loading and the flux rate through the filter bed. The nature of the water must also be taken into account for example oil content, polyelectrolyte residue etc.  In many of the applications OPS are involved the water is very unpredictable therefore we install a backwash:.

The backwash is required for sand filters and media filters alike, and there must be water available at all times to complete the backwash. Where the specification allows, OPS will incorporate off the shelf items into a plant to reduce CapEx.
