IDA 2022 World Congress: Sydney

Charting Resilient Water Solutions

The International Desalination Association’s flagship event, widely recognized as the premier event on advanced water treatment solutions in desalination and water reuse, returns to Australia a decade after the 2011 IDA World Congress held in Perth. The World Congress will take place during the week of October 9 – 13, 2022, in Sydney, Australia, at the International Convention Center Sydney (ICC Sydney).

IDA World Congress 2022 will consist of panel discussions, an excellent technical program, keynote presentations, an industry-driven exhibition, unparalleled networking opportunities, and specialized workshops. Global attendance from public and private sector leaders, researchers, and academics in desalination, water reuse, energy, environment, and project finance will provide knowledge-sharing and discussion opportunities for participants on many technical and business topics to ensure a secure water future.

First held in 1987, the IDA World Congress has been a global meeting point for promoting the appropriate use of desalination and water reuse technologies as a critical part of addressing the world’s freshwater shortages. The theme of the 2022 World Congress is Charting Resilient Water Solutions and how to secure a sustainable future that efficiently meets the growing water demand, threats to water security, and the increasing frequency and severity of droughts resulting from climate change.

We are looking forward to seeing you in Sydney!

Mrs. Shannon McCarthy, IDA Secretary General

EDS 2022: Las Palmas

Water and energy are the issues of this millennium.

This conference on desalination for the environment will be devoted to advances towards providing fresh water for all, at affordable cost and at economical energy requirements. With limited and depleting natural sources, desalination can supplement some of the critically lacking amounts of water needed for sustainable development.

Its place in the water cycle will be discussed. The conference will overview the most recent developments in desalination technology, its cost and extent of application, including socio-economic and environmental issues.

It will bring together research scientists, decision makers, managers, design engineers and operators from water companies, industries, government departments, consulting firms, research institutes and universities.

The place of industry, research and government decision making in this booming market will be addressed.

Why and how desalination should be integrated into the national or regional water management plans, ensuring socio- economic and environmental benefits, will be the focal point of the conference.

Conference Topics will include:

  • Feedwater pretreatment for desalination
  • Seawater desalination by reverse osmosis
  • Brackish water desalination
  • Nanofiltration, ultrafiltration, microfiltration in water treatment processes
  • Forward osmosis
  • Pressure retarded osmosis
  • Removal of specific compounds

Zero Leaks: Technical Services


Protec Arisawa has you covered with all the replacement parts, field service support and operator training to ensure your system is operating leak-free and safely. 

The membrane housing is meant to be a closed system and all water should be contained within and all leaks stopped as soon as possible. The outside of the vessel, especially the head area, is not designed to be wet and no sitting water should be present. Protec can help you identify the cause of vessel leaks, get the proper replacement parts and provide our expert team to fix them. 

Protect your asset! No leaks or external water should be tolerated on your system. Subject to operational uptime, seals have an average life of 3-5 years and should be inspected and changed regularly. High and low pH exposure can decrease the life of a seal and the frequency for change will vary depending on how the system is operated and cleaned. 

Enough seals for at least 10% of the vessels should be kept in stock at an operating facility and changed regularly. It is important for every operating plant to keep a safe level of shelf spares on site for emergency and routine maintenance. Permeate ports, thrust cones, membrane adapters and shims are common items that should be on hand.

  • Have you checked your seals lately?


  • Did you know vessel leaking and external water can damage your vessel?

  • What spare parts do you have in stock?


  • Want to know how to prolong the life of your vessel and safely operate the membrane housing?


Protec Arisawa’s field service team provides operator training and general maintenance guidelines to ensure seals are secure and the vessel integrity has not been compromised. Our highly experienced field service engineers and technicians will efficiently and expertly disassemble, clean, inspect, and replace all the parts of the pressure vessel to ensure seals are securely placed and the vessel’s integrity has not been compromised. Fixing leaks and keeping vessel heads dry will ensure the safe operation of the system and prolong the life of the vessel. Should you need assistance in troubleshooting pressure vessel leaks, please contact Protec Arisawa or your Original Equipment Manufacturer (OEM). 

Protec Arisawa keeps a large inventory of spare parts at our factory in Vista – CA, for immediate delivery to OEMs and End-users.  All vessel parts should be kept clean and free of debris and corrosion. All internal and external vessel parts should be regularly inspected for possible cracks or wear.  Contact your authorized Protec Arisawa representative or account manager today for part numbers and pricing. 

Contact Protec Arisawa, or your system OEM, for parts pricing, trouble-shooting and field service assistance to get your plant leak free and ensure you have a safety stock of all vessel parts.
