Opis:
Subject of this work was carrying out researches on removal of petroleum derivates in laboratory stripping tower. In researches model water was used, which was mixture of distilled water and petrol and diesel fuel mix in ratio of 1 to 3, next it was submitted to aeration. Repelling of petroleum derivatives was med in 4 series, starting researches from minimal concentration 0,132 µg/dm3 to 3,992 µg/dm3. Level of each concentration resulted from concentrations found in underground and superficial water based on researches made by authoress. As a result of stripping process outcomes were between 53,9 and 82,7%, lowest effects were achieved in III series – 44,8%. Observation was made, that during the process petroleum derivatives was removed gradually in III series, meanwhile in other series from the beginning high level of reduction was reached. Carried out stripping of petroleum hydrocarbons from water to air confirms relatively efficient method enabling lowering of their content to safe level. This process can be used to treatment of underground and superficial water with wide range of concentrations.

Opis:
Dispersing oil spill method is based on a interfacial tension reduction between water and oil through introduction a surfactant, so that spilled oil is changing its structure by dispersing in water. As a result of this process comes to break up oil contamination plume into smaller droplets, which is followed by its further dispersion in water. For study a 0.1% Rokrysol was used. The detergent was containing 30% of non-ionic surfactants, and 60% of anionic surfactants. In first research series the same amount of mixture and varying amounts of surfactant (SAA) were added, and in further series an established dose of the same surface active agents was added to varying amounts of crude oil. After mixing water with SPC emulsion was forming, which was decanted. The purpose of this paper was to determinate the possibilities of petroleum compounds removal from water with SAA usage.

Opis:
Aeration is the preceding process in chemical coagulation and it is applied to cause separation of dispersed petroleum hydrocarbons from wastewater. Chemistry of this process is based on long-chain hydrocarbons molecules breakdown by introducing oxygen to dangling bonds of hydrocarbon chains resulting in a breakdown into smaller chains. Then, in coagulation process by means of an added chemical bonding agent smaller hydrocarbons are recombined into large aggregates that sediment or flotate. Chemical and physical properties diversity of these substances has forced the need to develop methods that in most possible and efficient will obviate or reduce pollution caused by petroleum products. In this study the aeration – coagulation system was examined in petroleum products disposal from water. In laboratory research average petroleum products removal efficiency amounted to 54.43%.

Opis:
Most of used mineral and organic sorbents are hazardous waste and, therefore, in accordance with actual law regulations must be converted thermally or deposited in the special landfill for hazardous waste. Up to now both methods are expensive and burning methods are still watch as a controversial method . The optimal solution would be sorption materials that could be used repeatedly, without the need for costly and cumbersome lanfilling. Sorbents, which due to their properties could be used repeatedly, are MSW composts generated from mixed or only organic municipal waste. In this study we have investigated the rate of degradation of motor oil on MSW waste composts from two different technologies. Comparison of degradation efficiency, was calculated in comparison to the commercial sorbents. As sorbents were used organic (Peatsorb) and mineral (EcoDryPlus) materials which are in common use and available on the market. Both commercial sorbents were different in case of pH value and amount of biogenic elements and organic matter. Composts used in experiment also were characterized with high EC value, what could be a factor of microbial activity inhibition. During the experiment the total amount of standard diesel oil available on every petrol station and individual n-alkanes with carbon chain length from C8 to C19 was determinate. For comparison additionally was determined content of C20 and C21 n-alkanes. During the experiment, there were observed more intensive oil degradation processes on waste composts in comparison to commercial sorbents. Microflora which use n-alkanes as a carbon source, ensured quick (noted after 22 days of the experiment), reduction of the amount of hydrocarbons contamination in the samples, and thus the possibility of re-use of compost as a sorbent. The observed rapid degradation process, indicates the direction of the recovery of compost waste, used previously as a sorbent for the removal of petroleum contaminants (diesel oil). Undoubtedly, this is a cheaper way than the thermal incineration or storage.
