S-Metalltech 98 Ltd founded in 1998 works on one hand as a R&D workshop for universities and industrial companies and on the other hand as a manufacturing base of special materials applied in the field of environmental protection, electrical industry, automotive industry and nuclear reactor technology – cooperating with many of home and foreign partners.
Based on a highly selective adsorbent/ion exchange resin the S-Metalltech Ltd have developed an arsenic removal equipment-family under AsMet brand. With this special cerium-hydroxide base adsorbent material the company offers an economical and simply solution for the waterworks, local governments, food companies (having own wells with arsenic contaminated waters), and other companies working in the field of water treatment for reducing the arsenic content of the waters they supply or use below the limit prescribed by the EU (10 mg As/litre water).
The fully automatized equipments work without any supervision, energy- and chemical consumption. The AsMet technology is easy to fit into newly designed water treating systems and match to existing water treating systems too.
The AsMet filter material (adsorber) can be regenerated. Depending on the amount of the adsorber and the water chemistry, the regeneration of the adsorber saturated with arsenic should be carried out in 4-12 months. At the final „worn out” of the adsorber (7-10 years) it should be changed. This waste material is not hazardous.
The supply of the citizens with drinking water meeting with the arsenic limits defined by EU during the derogation period in Hungary can be solved with this small arsenic filtration equipments settled e.g.in the central points of the settlemets.
Another benefit of the AsMet-technology and equipments is that they can solve economically the arsenic problems not only at drinking waters but at irrigation waters too. The small and middle agricultural companies can solve the arsenic mitigation the irrigation water resulting in significant reduction of the arsenic content in the fruits and vegetables avoiding the market disadvantages.
S-Metalltech Ltd is working on a R & D project, based on the production technology of the arsenic adsorber material – aiming at develop an adsorbent material family which can separate from the water the arsenic, boron, iodine, antimony, and the fluorine contaminations. The fluorine adsorption solves easily the problems not only at drinking water, but at purification of semiconductor manufacturing waste water too.
One of the newest products of the S-Metalltech Ltd is a small and mobile arsenic detector equipment. This equipment makes it possible to measure the arsenic content of the drinking water at the site. There are a huge amount of interests from abroad to this new application.

The design and implementation of complex water engineering solutions for developing countries has always been and still is a distinguished area of Hungary’s international cooperation. Hungarian experts have several success stories from over the years in providing solutions in – amongst others – water management, well drilling and in irrigation.
The Public Relations Directorate of the University of Szeged has announced that a system for forecasting precipitation and flash floods is being implemented in the Hungarian–Serbian border region. The project will provide valuable assistance for preventing damage in the future.
The water crisis – that is the theme of the year’s most important event in Hungarian diplomacy, the Budapest Water Summit to be held on 15-17 October. Water shortages and the severe pollution of water resources are hazards that many hundreds of millions of people face – preventing the catastrophe is everyone’s shared task and responsibility.
The Sustainable Development Goals – adopted in the Summit of Prime Ministers and Heads of State between 25 and 27 September 2015 – are based on the eight Millennium Development Goals (MDGs).
It is a necessity to pay more attention to the ever increasing pollution of the waters. Conventional waste water treatments are not suitable to remove all the incoming pollutants in the treatment plants. That is the reason why Nyírségvíz Zrt. has started a development program.
The United Nations Environment Programme (UNEP) and the International Union for Conservation of Nature (IUCN) have produced a water management manual based on the principles of green infrastructure. The purpose of the publication is to popularise the solutions, and to present efficient and sustainable projects already in operation that use green or hybrid (traditional – gray and natural – green) infrastructural solutions in the field of water management.
There is no life without water – this is an unquestionable truth for everybody, but has anyone ever thought of the fact that without water there is no development, either? Talking either about the basic fact that water is essential for the development of plants, or the ingenious inventions of later ages, we have to admit that water significantly determines our lives.
The purpose of the document entitled Groundwater Governance – A Global Framework for Action is to make the importance of sustainable groundwater governance clear to political decision-makers.
At the global level, three of every four jobs are related to water in some way. The 2016 World Water Development Report examines the links between water and jobs, employment and economic development. The key findings of the report are summarised below.
