Abstract:

Industrial production of cellulose is an energy intensive process. Businesses aim to utilized as much input energy, materials as possible while minimizing the waste as well. In addition to the main product – cellulose and large amounts of organically polluted water which is subsequently treated in waste water treatment plants. This PhD thesis deals with formation of suitable mixing formula for sludge from cellulose production and available materials (waste) from close neighborhood of Biocel Paskov a.s. so that well balanced cofermentation products are achieved. This mainly involves grass from

Abstract:

<p>Possibilities for energy recovery from sludge at Chişinȃu wastewater treatment plant have been investigated and evaluated. One way of recovering energy from sludge is to produce biogas through anaerobic digestion. Which method of biogas usage that is to prefer in Chişinȃu has been evaluated from a cost-efficiency point of view. There is a possibility that a new waste incineration plant will be built next to the wastewater treatment plant, and therefore solutions that benefit from a co-operation have been discussed. The results show that biogas production would be suitable and profitable in

Abstract:

Bromide and nitrogen are wastewater effluent constituents that have raised concern for their potential to affect disinfection byproduct (DBP) formation at drinking water treatment plants (DWTPs) downstream of wastewater discharges. Despite the toxicity of brominated and nitrogenous DBPs, wastewater treatment does not usually remove bromide and nitrogen prior to discharge. Bromide is a conservative chemical and thus is not removed from surface waters via natural transformations after being released, although it may be diluted. Nitrogen is biologically reactive; it can be transformed and removed

Abstract:

Master of Science<br>Department of Civil Engineering<br>Natalie Mladenov<br>In the United States approximately 37% of the 4 trillion kWh of electricity is generated annually by combusting coal (USEPA, 2013). The abundance of coal, ease of storage, and transportation makes it affordable at a global scale (Ghose, 2009). However, the flue gas produced by combusting coal affects human health and the environment (USEPA, 2013). To comply with federal regulations coal-fired power plants have been implementing sulfur dioxide scrubbing systems such as flue gas desulfurization (FGD) systems (Alvarez-Ayu

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:

This report examined efforts to manage combined sewage overflows and create effective stormwater management plans. To provide background on the issue, a brief history of sewage management was provided, along with the legal history regarding water quality, sewage and CSOs, effects of CSOs and current green infrastructure methods for dealing with CSOs. The report then compared the efforts of three cities--Portland, Oregon; Philadelphia, PA; and Chicago, IL--to improve water quality and manage CSOs and stormwater. From the examination of the efforts of these cities the author derived a list of te
