Phenol removal from industrial waste waters by horseradish (Cochlearia armoracia L.) peroxidase
2003
Nedic, L. (Strucna skola "Sveti Sava", Bujanovac (Serbia and Montenegro)) | Stanisavljevic, M.
This paper presents a process for phenol removal comprising a reaction step in which phenol is polymerized in the presence of an enzyme horseradish peroxidase. A crude preparation from horseradish roots was used as a low purity source of the enzyme. The technical feasibility of the process was studied using 1 to 10 mM synthetic phenol solutions. Experimental results showed the potential of the proposed technique. A phenol conversion higher than 90% was observed at the polymerization process.

2003
Jovanovic, D. (Fakultet zastite na radu, Nis (Serbia and Montenegro)) | Pavlovic, D. (JKP za vodovod i kanalizaciju "Naissus", Nis (Serbia and Montenegro))
There have been given research results of quantitative and qualitative indices of communal and industrial waste waters of Nis. The research was carried out by the Institute "Jaroslav Cerni" (group of authors) and JKP "Naissus" (4) with the goal of defining as reliable parameters as possible in order to draw up plans for a central wastewater cleansing plant in Nis, as well as several necessary treatments of the industrial waste waters. There have been presented quantities, load and expected load of the total waste water, basic characteristics of urban and natural recipient, waste water influence on the river Nisava and needed degree of cleansing.

Perovic, S. (Kombinat aluminijuma, Podgorica (Serbia and Montenegro)) | Kolinovic, R. | Grzetic, I.
Processes like QMS (Quality management systems) and EMS (Environmental management systems) consist of series of procedures/elements, among which are operative or working procedures. One of these procedures is control of waste waters from the Aluminium Plant in Podgorica, Montenegro (Serbia&Montenegro). This procedure controls the order of activities, the responsibility, the input and output documents, with the exclusive aim to measure the effects of protection of surface and underground waters and to review the EMS of the company for the waste waters.

Effect of wastewaters from the Novi Sad [Serbia (Serbia and Montenegro)] Oil Refinery on the Danube water and sediment quality at the old and new discharge sites in 2004
2005
Roncevic, S. E-mail:srki@ih.ns.ac.yu | Dalmacija, B. | Krcmar, D. | Aleksic, A. | Jovic, B.(Prirodno-matematicki fakultet, Novi Sad (Serbia and Montenegro). Departman za hemiju)
Wastewater from the Novi Sad Oil Refinery, Serbia (Serbia and Montenegro) had been previously discharged to the Danube river between the raw water wells. In order to protect water supply source, the collector discharge was displaced downstream, outside the raw water wells area. In 2004, the quality of Danube river water and sediment was monitored at the sites of the old and new collector discharge of the Oil Refinery wastewaters, as well as at two control (reference) sites. The paper presents chemical quality parameters of water and sediment, characterizing oil contamination. Significantly increased contents of oil contaminant were measured in the Danube river sediment at the old discharge site compared to other sampling points, which is a consequence of many-year accumulation, as well as in the Danube river water at the new discharge site, as a consequence of the present wastewater discharge.
اظهر المزيد [+] اقل [-]Treatment of wastewaters from sugar processing plants by active sludge procedure - possibility of water recirculation
2004
Krcmar, D.(Prirodno-matematicki fakultet, Novi Sad (Serbia and Montenegro). Departman za hemiju) | Dalmacija, B. | Klasnja, M. | Ivancev-Tumbas, I. | Becelic, M. | Jovanovic, D.
The paper is concerned with the procedures of treatment of wastewaters from sugar-processing plants. A short survey is given of both the aerobic and anaerobic procedures with a special regard of the possibility of recirculating the treated wastewaters. Data are presented for treatment of wastewaters originated from sugar-processing plants by the active sludge procedure carried out on a laboratory scale. It was concluded that thus purified water, after final membrane treatment, could be recirculated to the production process.
