Trudno wyobrazić sobie codzienną pracę dyspozytorską, ale również zarządczą, bez odpowiednio dobranych i dostosowanych narzędzi informatycznych, które monitorują i nadzorują system produkcji, dystrybucji i rozliczenia ilości dostarczonej wody.
W artykule prezentujemy Program Wodny, Strategię Spółki, narzędzia informatyczne oraz opomiarowane obszary...
Awarie każdemu przedsiębiorstwu wodociągowemu spędzają sen z powiek. Jak je szybko zlokalizować? Kiedy i gdzie wysłać ekipę diagnostyczną? Pomocne w takich przypadkach okazują się informatyczne systemy i platformy. W Artykule opisujemy przypadek zidentyfikowania awarii oraz późniejsze jej poszukiwania z wykorzystaniem informatycznych systemów monit...
Funkcjonujące narzędzia informatyczne w przedsiębiorstwach wodociągowych w większości przypadków stanowią oddzielne nie powiązane ze sobą systemy działające indywidualnie. Wprowadzenie powiązań pomiędzy nimi pozwala na zebranie danych rozproszonych do jednej aplikacji poprzez utworzenie relacji pomiędzy nimi. W przedsiębiorstwie może funkcjonować k...
The purpose of this work was to analyze work of the sludge part of the wastewater treatment plant in Żory.

This paper presents the possibility of using sodium trithiocarbonate to remove heavy metals such as copper, nickel, and tin from industrial wastewater generated by the production of printed circuit boards (PCBs). Initial metal removal studies aimed at selecting an effective precipitant and optimizing the precipitation process were conducted on an l...
Our paper presents the possibility of phenol removal from post-processing wastewater originating from an experimental simulation of the underground coal gasification process carried out in the Barbara Experimental Mine in Mikołów, Poland. The application of initial coagulation-flocculation processes with iron(II), iron(III), aluminum, titanium(IV),...
Abstract: The possibility of chelated copper ions removal from wastewater from the production of printed circuit boards using Na2CS3 as a precipitant agent has been presented. The use of Na2CS3 (pH 9–9.5, FeCl3 1 mL/L, E= +82 mV) enabled successful precipitation of the complexed Cu(II) ions from wastewater (Cu 0.85 mg/L) containing potassium and so...
The possibility of Cu(II), Ni(II) and Sn(II) removal from model solutions and real wastewater from the production of PCBs using Na2CS3 for precipitation was presented in this paper. The testing was carried out on a laboratory scale using model and real industrial wastewater containing additives in the form of complexing compounds used in the produc...
The possibility of removing organic compounds from wastewater originating from the photochemical production of printed circuit boards by use of waste acidification and disposal of precipitated photopolymer in the first stage and the UV-Fenton method in a second stage has been presented. To optimize the process of advanced oxidation, the RSM (Respon...
A concd. wastewater from electrochem. tin plating
(3100 mg/L Sn) was neutralized with NaOH to pH 6.5
and then with (CH3)2NCS2Na to decrease its redox potential
from -265 mV to -387 mV (redox electrode). The concn.
of Sn in wastewater decreased from 3100 mg/L down to even
1.05 mg/L. The pptd. solid was dried, calcined and reduced
with activated C. T...
Wastewater from prodn. of printed circuit boards was
treated with CaO2, FeSO4 and H2SO4 at 18°C and pH 2–4
for 60 min (Fe2+ concn. 400–600 mg/L, CaO2 concn.
7500–9500 mg/L). The COD value in the system decreased
from 1690 mg/L down to even 339 mg/L. The results were
presented as polynomial regression equations. The concn.
of Cu2+, Ni2+ and Sn2+ ion...
Dokument przedstawia zakres prac wykonanych przez Główny Instytut Górnictwa i Politechnikę Białostocką i przedstawia syntetyczne wyniki konfrontacji rezultatów NPF przedstawionych w układzie tematycznym pól badawczych z zapisami podstawowych dokumentów strategicznych, operacyjnych, projektów foresight oraz wybranych ustaw.
The paper addresses the problems connected with sewage sludge dewatering. The premise of the study was the analysis of whether there are opportunities to increase the efficiency of dewatering sludge, a relatively low-cost involving the use of innovative polymers. The authors analyzed the impact of the new type of polyelectrolyte gel on the effectiv...
The title wastewaters and aq. CuSO4, NiCl2 and SnSO4
solns. were studied for toxicity against an aerated activated
sludge by respirometry to det. their inhibition degree.
The highest inhibition degree (near 100%) was obsd. for
Cu-contg. solns.
