Cuba: Microfiltration and ultrafiltration for drinking water treatment

In the framework of the EU project “Mas agua para todos” a short course on membrane technology was performed in Havana, Cuba for 20 water professionals that work in academia, planning, and in the water treatment and distribution company of the city of Havana. The topics included theory, cases studies and applications of microfiltration and ultrafiltration in the treatment of surface water.

Location: Havana, Cuba.
Duration: June 3-5, 2014
Lecturer: Dr. Sergio Salinas

Brazil: Membrane technology for drinking and wastewater treatment


The refresher course for 20 IHE Delft alumni of the region (South and Central America) included topics on technical and management aspects of low pressure membranes for drinking and wastewater treatment: innovative and sustainable technologies and management of water and sanitation services.
Since the mid 1990’s, the use of low pressure membranes (MF and UF) processes has grown rapidly. One of the main drivers for the increase in MF and UF growth was the increasingly stringent environmental legislation implemented in the last decade dealing mainly with disinfection of water (e.g. Giardia and Cryptosporidium removal guidelines).
The course provided theoretical and practical knowledge on the design, operation and management of membrane processes in the water and wastewater sector. Specific membrane related problems such as membrane fouling and cleaning were dealt with in detail, including pre-treatment options and the latest developments in monitoring and controlling fouling.
MF/UF process design schemes for the treatment of drinking water, and membrane bioreactors in waste water treatment (MBR) applications were also covered.
Furthermore, the course discussed current developments in the use of low pressure membranes for decentralized systems and emergency situations, and their contribution to the achievements of the MDGs. In addition, the course also focused on sharing local experiences from the participants.
During the course, a couple of field visits was arranged to the largest water reuse facility in Sao Paulo and also to the a new wastewater treatment plant with ultrafiltration membranes in the vicinity of the course location.

Bolivia: Refresher Seminar on Small Water Supply and Sanitation


The refresher course ” Small Water Supply and Sanitation: Serving the disadvantaged communities in semi-urban and rural areas in developing countries” targeted 20 IHE Delft alumni from Central and South American countries and also 5 local professionals. Participants of this course are professionals (from the region) that are involved in Water Supply and Sanitation (WSS) for cities, peri-urban, small towns, slum areas and rural areas. This course is aimed at updating their knowledge with state-of-the-art technologies and practices in the field of small WSS and to highlight its potential in the current and future efforts to improve the livelihood of disadvantaged communities.

Recently there has been a resurgence of small-scale and decentralized systems for WSS. A number of innovative, robust, technologies that use locally available resources. They have shown success in terms of providing safe drinking water and acceptable sanitation with considerable improvement in health and environmental impacts. Moreover, new approach of decentralized (local) governance of WSS are believed to play key role in providing sustainable services.

This refresher course discussed new approaches and challenges of emerging systems and it enabled the professionals in these practices update their knowledge and come abreast of the new developments. It also provided a platform/network for sharing experiences of professionals from the Central and South America as well as other regions.
