NX Filtration, specialist in innovative hollow fiber membrane solutions, was selected to supply its hollow fiber nanofiltration membranes for the optimisation of the Dumai City Water Treatment Plant in Indonesia. The project, for the Ministry of Public Works and Human Settlement of the Republic of Indonesia, the World Banks’s National Urban Water Supply Program (NUWSP) and the Local Government of Dumai City, contributes to the goal of providing access to improved water sources.
The nanofiltration system for the city of Dumai, an important trade hub in the province of Riau on the island of Sumatra, will have a capacity of 50 litres per second (180m3/h), consisting of 120 NX Filtration dNF80 membrane modules. With this system, the local Masjid river can be turned into a valuable source for the supply of drinking water to the city of Dumai. This river contains high amounts of colour and various pollutants, which are accumulated in the river during its flow through the rainforest.
The project was initiated by PT. Bayu Surya Bakti Konstruksi, an Indonesian specialist in constructing water and wastewater treatment plants, in collaboration with PT. Bumi Kirana Asri, Indonesia’s local distributor for NX Filtration’s products. Through a series of pilot tests, that were conducted over the past year, these parties demonstrated how the hollow fiber nanofiltration system could effectively remove colour and various pollutants from the peat water, and as such form the basis for municipal water supply.
Robert Gerard, Commercial Director at NX Filtration, commented, “Our hollow fiber nanofiltration technology offers a unique one-step solution to produce drinking water by removing colour, viruses, bacteria and micropollutants from the Masjid river. We have already successfully demonstrated our technology at various similar locations throughout South East Asia, as well as at a wide range of municipal and industrial applications in Europe and North America. We are proud that our technology will now also contribute to a reliable, affordable and sustainable drinking water supply for the city of Dumai.”
Nyoman Yasa, CEO at PT. Bayu Surya Bakti Konstruksi, added, “With NX Filtration’s technology we are able to turn a local river into a valuable source of drinking water for the city of Dumai. A series of pilot tests quickly showed us that NX Filtration’s nanofiltration technology would enable us to produce excellent water quality, which could not be achieved with conventional treatment methods. Important additional benefits are that this can be done in one single step, without pre- treatment and avoiding the use of a significant amount of chemicals. We see great potential to introduce this technology at similar locations throughout the region.”
The project is expected to be commissioned in April 2021 and is partly financed by the World Bank through its National Urban Water Supply Program (NUWSP), which seeks to provide access to improved water sources for the population and strengthen the operational performance of water service providers in selected urban areas.
