“…The development of the Discfilter as a separation technique for suspended solids from the MBBR plant at the Sjölunda WWTP represents a good example on more recent process development work. Disc filtration in this application was initially tested and developed at the Sjölunda WWTP (Persson et al, 2006). With nominal pore size openings of either 10 or 18 µm approximately 5 mg SS/l, or less, could be achieved in the Discfilter effluent without preceding coagulation/flocculation.…”

VA SYD is a publicly owned organization and serves around half a million people in southern Sweden with water and wastewater services, VA SYD has over the years developed a close cooperation with suppliers, contractors and universities. This co-operation model was fundamental when the upgrading concept for nitrogen removal was conceived for the Sjölunda WWTP in the 1990ies.The process led to the establishment of two novel biofilm process concepts, the high rate NTF and the MBBR process for post-denitrification. The development tradition still prevails and in the last years the development of a novel Discfilter technique for suspended solids removal from a MBBR plant for denitrification was conceived at the Sjölunda WWTP.The VA SYD model of leading edge practice and research where different stakeholders cooperate has proven to be fruitful for all parties. In the near future the plants in the VA SYD region will have to be refurbished, and upgraded for new requirements. In this work the R&D tradition of VA SYD will be a strategic asset for the future.

“…Since 2005, research on and commercialization of the removal of suspended solids (SS) by microscreens with woven media (either Disc filters or Drum filters) downstream of an MBBR have taken place. 3,4 The examination of the system's flow requires a lot of time and effort when designing a sewer network traditionally. The design of a sewer system is extremely challenging because so many crucial criteria/checks must be met at once.…”

The water-carried sewerage system has replaced the older, more basic technique of excreta disposal as the cities have grown. The infrastructure of any society's water supply and sewage system is crucial. The purpose of a sewer network is to move home or industrial waste water from a source location to a treatment facility or disposal site. The sewage system consists of a network of sewer lines that, at their nodal points, collect and discharge waste materials into a separate network of sewer lines. Since then, a lot of researchers have made contributions to this topic. As a result, an effort has been undertaken in this paper to gather data from research papers on the design of sewerage network systems. The objective of this paper is to proposed a treatment unit and design of sewerage network for Saatvik Vihar Phase-II, Indore (Madhya Pradesh), with the help of SewerGEMS software also using the process of Moving Bed Biofilm Reactor (MBBR) for the cleaning of wastewater of the society.

“…Both were then followed by a downflow fine sand filter as the second stage. The results of this innovative study demonstrated that the downflow second stage filter plays an integral role in achieving a turbidity of less than 0.5 NTU Persson et al (2006). evaluated disc filtration for the separation of flocs from a moving bed bio-film reactor.…”
