Perspectives are different frameworks from which to explore the knowledge around sustainable sanitation and water management. Perspectives are like filters: they compile and structure the information that relate to a given focus theme, region or context. This allows you to quickly navigate to the content of your particular interest while promoting the holistic understanding of sustainable sanitation and water management.
This webpage of Aqua Membranes presents the change of the membrane filtration industry with its unique three-dimensional Printed Spacer Technology.
This factsheet describes the purification of recycled water specially the so-called 7-barriers process (Source control; Wastewater treatment plant; Microfiltration; Reverse osmosis; Advanced oxidation; Natural environment; Water treatment plant).

Microfiltration membrane technology provides a unique design solution for small communities (up to 10 000 people). This is especially true in remote locations where space and personnel are limited and where environmental considerations restrict or prohibit chemical and/or sludge disposal.

Three emerging treatment technologies, including membrane filtration, advanced oxidation processes (AOPs), and UV irradiation, hold great promise to provide alternatives for better protection of public health and the environment and thus are reviewed in this paper. The emphasis was placed on their basic principles, main applications, and new developments. Advantages and disadvantages of these technologies are compared.
