Abstract:

The tendency to increase the number of units processed per day at slaughter yards (up to 8000 hogs daily), as well as new regulations (recycling and waste laws) in Germany, necessitate extensive utilisation of the residuals coming from slaughter yard operations. Anaerobic digestion appears to be an ideal use for the wet pasty residuals, that have little structure and a water content greater than 70%. The anaerobic digestion of sludges from municipal treatment plants in digesters, has been recognized as the state of the art process for decades. Due to changes in regulations (demands on nitrogen

Abstract:

Water treatment plants produce enormous amounts of sludge. Due to increased environmental concern, recently, there is considerable amount of pressure on the water authorities for the safe disposal of the sludge. Currently, the most acceptable form of disposal is sanitary landfilling, which requires sludge to be dewatered to 20-40% of solids. One of the most commonly used dewatering techniques is sand drying beds. This process is popular because of its reliability, ease of use and low cost. However, one of the basic concerns with this process is the requirement of a large area of land. This cou

Abstract:

Waste water treatment in larger chemical and petrochemical plants affords the application of all available technologies for pollution abatement. Elimination of conventional and priority pollutants down to low concentrations in the effluent is necessary in the F.R.G. for the protection of surface waters. Special care is directed at chlorinated hydrocarbons. The WACKER-CHEMIE plant at Burghausen which produces especially chlorinated and organic silicon compounds uses a great number of in-plant measures, pretreatment steps and finally a two-stage biological purification to attain a high effluent

Beneficial reuse of drinking water treatment plant residues (WTRs) has been intensively studied worldwide in the last decades, but few engineering applications can be found. The majority of WTRs were directly reused in cake form (after dewatering), e.g., alum sludge cake as main substrate used in constructed wetlands (CWs), or oven dried and ground powdery form, e.g., sorbent for pollutant removal. However, WTRs reuse in such forms has several drawbacks, i.e., difficulty of recovering and easy clogging (in CWs), which result in limited WTRs engineering applications. Granulation or pelleting co

Abstract Water treatment plants are designed to continuously produce drinkable water, meeting defined criteria of potability. However, besides potable water, these plants produce sludges that are disposed of in the environment. The present work aimed to evaluate the sludges generated in two water treatment plants and disposed of in the margin of the Juturnaíba dam. Since alum has been used as a flocculating agent in these two plants, the concentrations of aluminum were measured in the sludges and in surface sediments. The generated piles are extremely soft to walk on and difficult to measure,

Abstract:

In recent years, triazine residues are often evidenced in surface waters as well as in underground waters. The European standards for the maximal level of each pesticide in water for human consumption is 0.1 µg.l−1 which raises problems for triazines such as atrazine or simazine. New molecules have been designed to replace atrazine and the aim of our study is to evaluate on a pilot plant the outcome of two triazines wich could be used instead of atrazine and simazine; these two triazines are cyanazine and terbuthylazine. These triazines are not removed by coagulation, floculation, decantation.

Abstract:

From the moment it was first indicated that use of aluminum chloride during purification of drinking water might be one of the triggers of Alzheimer’s disease, it took only a few years to almost abandon this practice worldwide. Now, two years after the initial evidence was presented that the cheapest possible replacement for aluminum chloride (ferric hydroxide, better known as ferrous sludge) significantly threatens soil fertility, there is almost no action. A robust case study was conducted among European drinking water treatment plants. First, it is reported that some samples of ferrous slud

Constructed wetlands (CWs) are sustainable technologies where the channels are filled with porous material and plants, which collectively remove pollutants, depending on the type of substrate and vegetation. This study evaluated CWs and their functionality by comparing three ornamental plants (Canna indica, Cyperus papyrus, and Hedychium coronarium) as a phytoremediation process of wastewater, in CWs filled with layers of porous stone–tepezil–plastic residues–soil (S-A), or in microcosms with layers of porous stone–tepezil–soil without the presence of plastic (S-B).

Arsenic in drinking water causes severe health effects and it is widely diffused in groundwater around the world. This paper presents the results of a survey about the main arsenic removal technologies employed in Italy and the main features in the management of real treatment plants. 19 drinking water treatment plans were involved in this study. The specific aspects analysed in this survey were: type of technologies applied in the drinking water treatment plants (water characteristics, ionic form of As in raw water, etc.), technical aspects (chemical dosage, treatment steps, hydraulic load, r

Abstract:

Increasing horticultural production under protected cultivation requires more detailed studies about the occurence of pesticide residues, due to the special and peculiar environment under controlled conditions, in which some pests, that are of little concern in the field, become important. The insecticide acephate and its methamidophos metabolite residues were evaluated in greenhouse-grown tomatoes and compared to an open-field tomato crop. The treatments: (a) check; (b) one application of 75 g a.i. acephate.100 L-1 water; (c) one application of 150 g a.i.100 L-1 water; (d) four applications o

Abstract At Linz-Unkel (Germany) sewage treatment plant the first full scale state-of-art EloDry-Pro® plant for sewage sludge has been constructed, consisting of the PYREG® reactor and the EloDry® belt dryer. The system is characterised by small footprint, flexibility, modular design and efficient energy management. The sludge dried using an EloDry® belt dryer undergoes staged combustion using the PYREG® module at around 6,500°C. This reduces the sludge to a fraction of its original volume while disinfecting it and removing micro-pollutants such as pharmaceutical residues. The residual ash, wh

Abstract:

As a rule, hazardous waste needs a pre-treatment, either a thermal or a chemical-physical one, before it can be disposed of at a landfill. The concentration of different kinds of treatment facilities at a Centralized Hazardous Waste Treatment Plant is advantageous. The facility of the ZVSMM at Schwabach is presented as an outstanding example of this kind of Treatment Centre. The infrastructure, the chemical-physical plant with separate lines for the treatment of organic and inorganic waste and the hazardous waste incinerator are described. Their functions are discussed in detail. Emphasis is l

Abstract A successful ground application of glyphosate for competition control was made on an 11-ha site planted with white spruce. During the application, monitoring was conducted of the buffer-protected stream before treatment and intensively after treatment. No herbicide was found in the adjacent waters. In addition, samples were taken of water-saturated soil at several locations on the site, frozen, and analyzed for glyphosate. Under the application and weather conditions that prevailed, no glyphosate was detected 24 hours after treatment with a trace amount detected in one replicate sampl

Abstract:

Increased rice cropping intensity, due to shorter maturity varieties and shorter turn around times between crops, has lead to an increase in burning of rice straw. This can have significant short and long term effects on the productivity of the rice cropping system. A glasshouse experiment was conducted using an Aquic Haplustalf soil to study the release of S from different rice residues (straw and ash) under different water management conditions (non-flooded and flooded), and with and without the addition of S fertilizer. Rice straw residues (0.086 and 0.108%S) and ash produced from them (0.1
