Abstract:

The removal of PCP from aqueous solution in contact with metallic iron was investigated by laboratory batch experiments. The decline in PCP concentration as well as inorganic parameters were monitored over time. Removal of up to 90% of the initial PCP was observed within 24 hours. The initial geochemical conditions of the PCP solution changed rapidly to basic and reductive conditions when in contact with metallic iron. Organic degradation by-products were not found during the removal of PCP using two distinct analytical procedures. Chloride ions analyzed in the solution after PCP removal were

Abstract:

<p> With the pollution of freshwater sources and the continual increase in freshwater demand due to rapid industrialization and population explosion, the globe is facing an eminent danger of scarcity of freshwater. One way to increase the water supply beyond the hydrological cycle is to reuse and recycle the waste water by developing an onsite recycling/reclamation technology. Such a bench-scale treatment technology was developed to treat the cooling tower blowdown water (CTBW) from the cooling towers of California State University, Long Beach (CSULB). The CTBW was treated by using electrodial

Abstract:

<p> The purpose of this thesis is to provide a combined theoretical and experimental approach to solve several enduring questions in wastewater chemistry. Firstly, the sulfate radical has been proposed as an alternative oxidant in advanced oxidation processes (AOPs). Its reactivity with dissolved organic matter (DOM) has not yet been studied and will be quantied in this work using electron pulse radiolysis. Next, it has been shown that DOM present in wastewater can act to impede the remediation of harmful pharmaceutical contaminants in the AOP. Using a new binding model presented here, this as

Several electrochemical processes are modeled at process levels and atomic scales. Processes are presented for acid generation and ion exchange media regeneration, along with corresponding process models. Transport and reaction processes in individual ion exchange beads are also modeled. Acids of mild strength (pH = ~1-2) are generated from electrolyte solutions and their strength is effectively modeled as a function of time. The regeneration of ion exchange media is also modeled, to close agreement with measurements, and the process model is reconciled with a model for solute flux from an

Microbial Fuel Cell is a novel technology that can be used for a waste water treatment in order to simultaneously remove carbonaceous matter and nitrogen while producing electrical power. Even if it is not an established technology so far, MFC could be a cost effective option for waste water treatment and the major challenge of this process will be the device scale-up. Exoelectrogenic bacteria are capable of converting the chemical energy of organic matter into electrical energy by transferring the electrons produced in the oxidation to the anode electrode.

The effect of supercritical water treatment on the composition of bio-oil was investigated. Preliminary studies were carried in batch mode using a bio-oil simulant. This bio-oil simulant was designed to mimic crude bio-oil by possessing the same functional groups as are found in crude bio-oil, but with reduced complexity. Experiments of this type allow to be gained of the reaction chemistry involved. These were then followed up by experiments using crude bio-oil. Critical process parameters for all these experiments were reaction time, bio-oil/water ratio, reaction temperature and pressure. On

This research focused on removal of aqueous IBP using five different oxidative techniques: ozonation, ozonation with hydrogen peroxide, ozone with sonication, sonication with hydrogen peroxide and sonication alone. IBP and chemical oxidation demand (COD) removals were monitored for experiments performed over a range of operating conditions: pH (4 to 7), temperature (5 to 25ºC

Abstract:

Wastewater compose an environmental risk as it contains high levels of nutrients, including phosphorus. Wastewater treatment plants (WWTPs) reduce phosphorus by using coagulants that precipitate soluble phosphate into metal phosphate, which is separated by settling. Coagulant flow is regulated by a control strategy, typically feedforward or feedback control. Feedforward is based on incoming wastewater disturbances whereas feedback control uses outgoing process values. Incoming phosphate is hard to measure and can be estimated using soft sensors. Modelling control strategies can help decide whi

Abstract:

Dricksvatten är en essentiell del av ett hållbart samhälle. Därför är det viktigt att säkerställa säkert dricksvatten genom fungerande vattenreningsverk. En viktig förorening att behandla är NOM, som i sig är ofarligt men som kan producera farliga föroreningar. En teknik som används för behandling av NOM är kolfiltrering. Hur ökad flödeshastighet och ökad kontakttid påverkade kolfiltrens effektivitet undersöktes vid dricksvattenreningsverket Norrvatten.
