1. Studies to Avoid Decreased Efficiency in Multiple Stage Biological Wastewater Treatment Plants: Concerning Forests Industry Effluents
Sammanfattning : Målet med den här studien är att förhindra effektivitetssänkningar i moderna biologiska reningsanläggningar för skogsindustriella avloppsvatten. Biologiska processer är vanligtvis effektiva när det gäller att reducera lättnedbrytbart organiskt material. Eftersom den utgörs av levande mikroorganismer (MO) är tekniken känslig. LÄS MER
2. Algal-Bacterial Photobioreactors for the Degradation of Toxic Organic Pollutants
Sammanfattning : The aerobic biodegradation of toxic organic volatile contaminants is always limited by the low aqueous solubility of O2. Therefore, intensive bubbling or surface aeration is required to supply the bacterial community with sufficient O2 to carry out pollutant mineralization. This can cause the hazardous volatilization of toxic volatile contaminants. LÄS MER
3. Solar-based physicochemical-biological processes for the treatment of toxic and recalcitrant effluents
Sammanfattning : Wastewater treatment is a worldwide necessity that is even more crucial to countries deprived from abundant fresh water sources or unable to afford advanced and costly processes. With this perspective, this thesis was conducted within an Egyptian-Swedish research collaboration that aimed to develop solar-based (as free renewable energy source available locally) process for hazardous wastewater treatment.

4. Emissions from Fires Consequences for Human Safety and the Environment
Sammanfattning : Accidental fires represent a risk for people from the heat and fire effluents produced. It is clear from fire statistics that it is, in fact, the toxic gases that kill and injure many fire victims. Further, there are a number of compounds that are readily produced in fires, which have important sublethal effects on humans. LÄS MER
5. Bioremediation of Toxic Metals for Protecting Human Health and the Ecosystem
Sammanfattning : Heavy metal pollutants, discharged into the ecosystem as waste by anthropogenic activities, contaminate drinking water for millions of people and animals in many regions of the world. Long term exposure to these metals, leads to several lethal diseases like cancer, keratosis, gangrene, diabetes, cardio- vascular disorders, etc. LÄS MER
