From 5th to 23rd March 2018 Ieva Berzina, the senior research technician from the Water Research Laboratory is doing experience exchange research in the Fuel Laboratory of Estonian University of Life Sciences.
From 28th February to 1st March team of Water Research laboratory hosted the 1st meeting of EU-LAC Health project Hi-Water (Efficient and affordable water treatment technologies to minimize waterborne diseases) in Riga. The meeting was attended by partners from Universidad Regional Amazonica (Ecuador) and Leibniz Institute of Polymer Research (Germany). During the two-day visit delegates participated not only in Hi-Water meetings but also visited laboratories of Institute of General chemical engineering, Biomaterials center, Water research laboratory and design factory. Technical excursion to Baltezers water treatment station and Wastewater treatment plant «Adazi» was performed to demonstrate how small-scale water engineering systems are operated in Latvia.
A first partners meeting of INTERREG the Baltic Sea region international cooperation programme BEST (Better Efficiency for Industrial Sewage Treatment, #R054) project occurred from 6th to 8th February. The aim of the project is to improve water resources management in order to decrease an effect of wastewaters and hazardous substances leeks on regional watersheds and the Baltic Sea. This way increasing a capacity of a public and private sector for water quality problems solutions.
The meeting was attended by partners from Finland, Germany, Russia, Poland, Ukraine and Latvia. RTU is grateful to organizers, especially Kajsa Rosqvist (the leader of BEST project) for making such an intensive and interesting programme of the meeting. RTU team was presented by Kristīna Tihomirova, Sandis Dejus, Jānis Zviedris, Arta Čakša-Lapsiņa and Tālis Juhna.
The meeting was opened by Esa Nikunen – director general of the Environment Centre of Helsinki City. Mr. Nikunen told about Finland progress towards zero biogen emissions into the Baltic Sea. Every partner had an opportunity to present their planned activities in the BEST project. Sandis Dejus presented aims and plans of RTU Water Research Laboratory, as well as talked about expected contribution from other partners and a resulting project impact. To compare legislation, evaluate the most important contaminating substances and understand which technologies are used in all of the partners’ countries, RTU scientists made a questionnaire. The questionnaire was presented by RTU guest expert Jānis Zviedris. Working in teams, project partners collected opinions on urgent problems, determining a structure for cooperation between municipalities and manufactures in wastewater treatment sector.
On February 7th, a seminar was organized with an aim to clarify what are the possible pitfalls for implementation of new technologies in manufactures and municipalities. Possible solutions and proposals list were also created. Kristīna Tihomirova presented a work done by RTU team.
