  • Devolping Pre-treatment Strategy for SWRO Systems

    Typically open-sea water intake structures are constructed in the shallow areas where sea water depth is in the range of 3m up to 10m. Due to this SWRO plant with open intake will have source water with high debris, suspended solids and aquatic organisms requiring a very elaborate pretreatment system. Thus Pretreatment design becomes an important part for a long term operation of the seawater ...

  • The smart solution to membrane fouling detection, monitoring and management

    Since the advent of membrane technology applications for large-scale commercial seawater desalination in the early Eighties, two critical issues in the application of the technology have emerged and persisted that drastically affected the way plant owners and operators managed these vital water production utilities, and subsequently impacted the total cost of water. The issues are the ...

  • Cleaning biofouled membranes early improves plant operation. Comparison of autopsy and cleaning results on a small BWRO and large SWRO

    Abstract It is a fact that all new reverse osmosis membranes start to foul as soon as they start operation. The only variable is the rate at which they foul. Most RO plants operate at a differential pressure (ΔP) of 1.5 - 3 bar. Cleaning usually occurs when the ΔP is 10-15% above the design specification. This paper explores the benefits of early identification of foulants ...

  • Results from 99 seawater ro membrane autopsies

    Abstract This paper presents results from 99 sea water reverse osmosis (SWRO) membrane autopsies carried out by the Genesys laboratory in Madrid from 2002 and outlines the technical issues surrounding fouling and scaling of sea water membranes. The authors discuss historical results of membrane autopsies and link recent trends and changes in plant design to potential fouling and ...

  • Design, operating and research experience at the Penneshaw Seawater Desalination Plant, South Australia

    Abstract This paper provides a historical perspective of the plant, including performance problems and how they were overcome, as well as key learnings from selected process R&D studies. The South Australian Water Corporation (SA Water) is a wholly-owned public water utility, responsible for the management of water and wastewater supply, treatment and distribution infrastructure, for ...

  • Reverse Osmosis Technology – KURIVERTER RC - Case Study

    Summary Applications using Reverse Osmosis membrane technologies are everywhere in our lives – from tiny under counter units polishing our drinking water through industrial units preparing water for processes or purifying effluents for reuse and massive seawater desalination plants producing thousands of m³ of drinking and irrigation water every day. The membranes used in this ...
