- [Show abstract] [Hide abstract] ABSTRACT: Some economic aspects of taxes and fees for the use of the environment have been discussed. The Polish environmental charge system is taken into account as an example of the tax system. The types of charges levied for use of the environment have been indicated as well as the persons and entities that must pay, rules of payment and the legal background in Poland. The revenues generated from environmental taxes have been shown on the example of European Union countries. Based on statistical data for Poland, the most important sources of revenue derived from fees for use of the environment were identified and analyzed both in terms of the type of payment as well as the geographical distribution of the entities which are charged.
- [Show abstract] [Hide abstract] ABSTRACT: The method of identifying areas of risk of failure in water pipe network has been presented including presentation and analysis of risk factors for failure in water main pipe network, the proposal of the method for identifying risk areas using a simulation model of the water distribution subsystems (WDS) operation, and an example of application. In the hydraulic model, the failures of main water pipes as well as the operation of the WDS in the case of contamination were simulated. The proposed method consists of preparing the so-called risk maps and the designation of areas in which the limit values for the identified risk, the first type and the second type according to the assumed risk categories (tolerated, controlled and unacceptable) were exceeded.
- [Show abstract] [Hide abstract] ABSTRACT: A direct effect of chemical disintegration of excess sludge is an increase in concentration of or-ganic compounds in the sludge liquor, expressed with the levels of soluble chemical oxygen demand (SCOD) and volatile fatty acids (VFAs). The substrate used in the study was activated sludge. The aim of the study was to determine susceptibility of disintegrated excess sludge to biodegradation and de-watering. A SONICS VCX-1500 ultrasonic disintegrator with automated tune-up was used. Thermal disintegration of excess sludge was carried out in water bath with a shaker. Disintegration of excess sludge by the hybrid method was carried out as a combination of the ultrasonic and thermal methods.
- [Show abstract] [Hide abstract] ABSTRACT: The feasibility of various composts to operate as sorbents for heavy metals (Cu and Zn) removal from wastewater has been evaluated. Three commercial composts obtained from municipal solid wastes (MWS), sludge sewage (SS) and poultry manure (PM) were selected as potential sorbents. Kinetic and equilibrium tests were conducted in order to assess the equilibrium conditions to remove metals from aqueous samples. For all composts, the maximum time necessary to reach the equilibrium was 240 min. The Freundlich and Langmuir isotherm models were found to fit the sorption data. The SS compost proved to be the one with highest removal capability for both assessed metals, while MWS compost showed to be the less suitable for this purpose. These results can be explained in terms of the compost surface properties, namely, with the cation exchange capacity.
- [Show abstract] [Hide abstract] ABSTRACT: The micellar enhanced ultrafiltration of model aqueous solutions containing inorganic nitrogen and phosphorous compounds was studied. In the experiments, cellulose membranes of 5, 10 and 30 kDa molecular weight cut-off and cetyltrimethylammonium bromide (CTAB) as a cationic surfactant were used. The concentration of CTAB amounted to 2 and 3CMC (critical micelle concentration). The influence of surfactant concentration, membrane cut-off and operating pressure on permeate flux, as well as on nitrate and phosphate separation was evaluated. The results showed that the presence of both nitrates and phosphates caused deterioration of the retention coefficient in comparison to separation efficiency achieved for one-component solutions.
- [Show abstract] [Hide abstract] ABSTRACT: Sample results have been presented of verifying three groups of methods of forecasting the time series of short-duration water distributions in city water grids. The analysis covered: ARIMA class models, the time series exponential smoothing methods and artificial neural networks. Since chronological sequences of observations from the immediate past were analyzed, the adopted models did not take any external variables into account. The forecasting errors in the case of multilayer perception neural networks were found to be comparable or smaller than the errors of prediction by the ARIMA class models and by the methods of the exponential smoothing of time series.
- [Show abstract] [Hide abstract] ABSTRACT: One of the operation rules of variable declining rate (VDR) filters states that the longest filtration runs are achieved when the highest flow through the most recently backwashed filter and the highest available head loss coincide. This rule has previously been published by Dabrowski, who used a simplified mathematical model of VDR filters developed by Di Bernardo. However, until now no experimental verification of this optimisation approach has been presented. A series of tests were carried out on a laboratory VDR filter plant, using a suspension collected from an industrial sedimen-tation tank and using alum as a coagulant. The results of the experiments were compared with com-putations carried out according to a combined unit bed element (UBE)-phenomenological model of deep bed filtration adapted to VDR operation by Mackie and Zhao. It was confirmed that the longest filtration runs did indeed correspond to the pairs of the highest H and q1/qavr. The UBE-pheno-menological model of deep bed filtration gave results of computations quite close to experimental results and improved the accuracy of calculations based on the theoretical model by Di Bernardo.
