A quick method to determine the content of sulfates in silicic and aluminosilicate fillers

The paper presents the possibility of using barium-selective electrode to a potentiometric determination of sulfates in silicic and aluminosilicate fillers. The results of sulfates potentiometric titration in silicic and aluminosilicate fillers are described. A statistical interpretation of the results was carried out. The recommended method is based on the end-point detection of sulfates potentiometric titration in hydro-alcoholic medium by means of barium chlorate(VII) titrant. The potentiometric titration, which uses an ion-selective electrode as the indicator for the end-point was applied as the analytical technique. The parameter ranges for accurate sulfates determination in model solutions and the method of samples' preparation for analysis were investigated

Use of prehydrolyzed coagulants for the enhancement of water treatment efficiency in the Czaniec Water Treatment Plant

Przedstawiono uwarunkowania techniczno-technologiczne eksploatacji jednej z największych stacji oczyszczania wody "Czaniec" w Kobiernicach, zarządzanej przez Górnośląskie Przedsiębiorstwa Wodociągów SA w Katowicach, zaopatrującej w wodę aglomerację śląską. Omówiono wyniki badań laboratoryjnych nad zastosowaniem grupy koagulantów (PAX XL 19F, PAX XL 1905, PAX XL 69, Flokor 1A, Flokor 1ASW, Flokor 1,2A) do oczyszczania wody w układzie koagulacji kontaktowej. Na podstawie uzyskanych wyników badań dokonano oceny skuteczności tych koagulantów w jednakowych warunkach temperatury oraz przy takiej samej mętności i barwie wody surowej, jak również przy jednakowych parametrach technologicznych procesu koagulacji i sedymentacji. Wykazano, że istotnym wskaźnikiem jakości wody w ocenie skuteczności jej oczyszczania jest absorbancja w UV (254 nm i 272 nm), która umożliwia monitorowanie ilości związków organicznych pozostałych po zastosowaniu różnych koagulantów. Ponadto przeprowadzono ocenę skuteczności procesu oczyszczania wody w zależności od jej pH, mętności, barwy i przewodności właściwej.The technical and technological conditions underlying the operation of the Czaniec Water Treatment Plant are discussed. Located in Kobiernice and supervised by the Upper-Silesian Water Enterprises, Katowice, this plant is one of Poland's largest water treatment plants, which supplies water to the agglomeration of Upper Silesia. The paper presents the results of laboratory investigations into the use of a group of coagulants (PAX XL 19F, PAX XL 1905, PAX XL 69, Flokor 1A, Flokor 1ASW and Flokor 1,2A) for water treatment in the contact coagulation mode. On the basis of the results obtained, the efficiency of the coagulants was assessed under the same conditions (temperature; turbidity and color of raw water) and technological parameters of the unit processes (coagulation, sedimentation). Of the water quality parameters, UV absorbance (at 254 nm and 272 nm) was found to be of significance to the assessment of treatment efficiency, as it enables monitoring of the amount of the organic matter persisting in the water upon the application of particular coagulants. The efficiency of the water treatment process was also related to the pH, turbidity, color and conductivity of the water

International audienc

The Reference Site Collaborative Network of the European Innovation Partnership on Active and Healthy Ageing.

International audienceSeventy four Reference Sites of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) have been recognised by the European Commission in 2016 for their commitment to excellence in investing and scaling up innovative solutions for active and healthy ageing. The Reference Site Collaborative Network (RSCN) brings together the EIP on AHA Reference Sites awarded by the European Commission, and Candidate Reference Sites into a single forum. The overarching goals are to promote cooperation, share and transfer good practice and solutions in the development and scaling up of health and care strategies, policies and service delivery models, while at the same time supporting the action groups in their work. The RSCN aspires to be recognized by the EU Commission as the principal forum and authority representing all EIP on AHA Reference Sites. The RSCN will contribute to achieve the goals of the EIP on AHA by improving health and care outcomes for citizens across Europe, and the development of sustainable economic growth and the creation of jobs
