Article
Full-text available
Energy neutrality of wastewater treatment plants is possible with constant and consistent optimization and implementation of new technologies. In recent years new process called deammonification has been discovered and implemented in treatment of side streams rich in nitrogen. With its implementation on wastewater treatment plants it is possible to...
Article
In order to be able to permanently settle other celestial bodies, it is necessary to create an efficient and closed life support system. Such a system will allow high autonomy and significantly reduce operating costs in a future colony. Grey water is a major waste stream in terms of the water volume generated by colonists, and its reuse is necessar...
Article
The aim of the study was to supplement the information missing in the literature on the influence of organic compounds speciation (percentage of chemical oxygen demand (COD) fractions, readily biodegradable and non–biodegradable dissolved organic matter; slowly biodegradable and non‒biodegradable insoluble organic matter ) in wastewater on chemical...
Article
Full-text available
The anammox process is an economically favourable nitrogen removal process; however, low growth rates of anammox biomass block its more widespread application. As different approaches on techniques for anammox bacteria growth acceleration were tested, this study focused on long-term evaluation of hydrazine addition in the start-up phase. Effect of...
Article
Full-text available
Stable and efficient nitrogen removal is one of main goals of wastewater treatment. Applying deammonification, beyond many advantages, results in the risk of the WWTP effluent quality violation in case of the failure of the process. Then nitrogen load to activated sludge is increasing rapidly which could therefore lead to quality violation in activ...
Article
One of the key technological parameters for highly efficient wastewater treatment methods is bacterial mortality. Protozoa are known for feeding on free floating bacteria, that initiate floc formation and participate in putrefaction process. Reliable protozoa removal methods are still unavailable which have negative impact on the development of the...
Article
Sludge foaming is a common problem in wastewater treatment plants negatively affecting operation of anaerobic digestion reactors. Therefore, in common practice, foam is removed from reactors without being fermented, leading to increase in sludge mass for disposal. However, foam is rich in lipids and can be a good source of methane if operational pr...
Article
This research sheds light on the gap in knowledge concerning the effect of temperature shock on nitrifiers. This phenomenon was analysed in context of mainstream bioaugmentation with nitrifiers cultivated in a sidestream partial nitritation process, which was recently experimentally confirmed to be beneficial in municipal wastewater treatment plant...
Article
Full-text available
The application of hydroponic cultivation fertilized with biologically nitrified synthetic urine can produce nitrate-rich fertilizer for lettuce (Lactuca sativa var. capitata L.). The mounting water crisis and depletion of natural resources makes nitrogen recovery from human urine a practical option. Nitrified urine can be used in indoor vertical h...
Article
Full-text available
This is the first study that identifies nitrogen loss and drier liquor parameters in a full scale sludge drying facility. Obtained data enabled proposing novel treatment based on deammonification process that allows not only nitrogen removal from drier liquor but also from gravity thickeners supernatant, the stream that is considered too cold for d...
Article
Protozoa are significant components of activated sludge which purify the effluent of free swimming bacteria as well as trigger floc formation. In addition, their presence is often used as an indicator of process quality. In classical models, the impact of protozoa on biomass is implicitly included in the bacteria decay rates, which in most cases gi...
Article
Full-text available
The combination of sidestream deammonification and bioaugmentation of the mainstream reactor using ammonia oxidizers from partial nitritation (PN) was not achieved before. This novel solution not only enables the efficient sidestream nitrogen removal, but also improves mainstream resistance to stress situations such as biomass washout or nitrogen o...
Article
Current data about disintegration of waste activated sludge (WAS) with free nitrous acid (FNA) do not provide information about the efficiency of concentrations higher than 6.1 mgHNO2-N/L and exposure times over 72h. Moreover, current references do not represent disposable soluble chemical oxygen demand (SCOD) release as data on COD consumption for...
Article
Full-text available
Soluble chemical oxygen demand (SCOD) release by free nitrous acid (FNA)/NO2 system is usually called “FNA disintegration”, despite lack of evidence that FNA is the main agent responsible for organic matter breakdown. The aim of this study was to investigate whether FNA or NO2 is the primary disintegration factor of thickened secondary sludge in a...
Article
Urine nitrification is one of the possibilities for the future recovery of water and elements for soilless crop production in space systems. The start-up of artificial urine nitrification was conducted for over 85 days in a sequencing batch reactor (SBR). Two free ammonia (FA) incidents occurred, which gave the opportunity to demonstrate the impres...
Article
Full-text available
In modeling studies, estimation of microorganisms kinetic parameters set is a key element for proper model operation and predictability. Nitrification process is very often, a crucial element of the wastewater treatment systems as bacteria responsible for ammonium and nitrite oxidation are slow growing microorganisms, making whole nitrification pro...
Conference Paper
Full-text available
Water and nutrients recovery are essential in regard to future deep space missions. Connection between each subsystem in life support system is necessary in order to create self-sufficient extra-terrestrial outpost. This is the case especially regarding to the wastewater treatment system, solid waste management and biomass production. Simultaneous...
Article
Full-text available
Chemicals addition at the mechanical part of wastewater treatment plant can improve overall treatment efficiency and help in solving some plant’s operational problems. Application of such process in the primary clarifiers, named as Chemically Assisted Primary Sedimentation, can also be a huge step towards energy balance improvement for the whole pl...
Article
Full-text available
Aeration is considered as one of the most energy consuming process during the wastewater treatment process and its proper design plays important role in further overall wastewater treatment plant energy balance. Design guidelines for aeration systems in mainstream treatment of municipal wastewater are well known, however there are some doubts about...

The off-gas method is one of two primary aeration efficiency examination methods. In off-gas method, exhaust air from aeration tank is collected by a floating hood and conveyed to a measurement module. In this part of the installation, gas flow is measured, collected air is dried, stripped of CO2 and subsequently oxygen concentration is measured. T...

Anammox and denitrification processes play important role in nitrogen removal in wastewater treatment. In final stage of nitrogen compounds metabolism nitrogen gas is produced and released to atmosphere. Process rates can be estimated based on amount of produced nitrogen, but this kind of procedure requires special equipment that may be a significa...
Article
Full-text available
Dynamic development of side-stream ammonia-rich streams treatment technologies creates need of new methods of control techniques. So far, most of available technologies are based on relatively simple sensors, such as pH probes. This article presents the results of an ion selective electrode used for controlling a one-stage deammonification process...
Article
Full-text available
For many wastewater treatment plants (WWTPs), side-stream treatment of reject water from digested sludge dewatering is a feasible opportunity to improve N-removal efficiency without costly plant expansion. Biological nitrogen removal over nitrite or combined partial nitritation (PN)-Anammox process has recently become a popular treatment method for...
Conference Paper
Full-text available
The aeration process is a very energy-intensive and requires continuous optimization. One of the aspects that enable further progress and improvement in this area is to develop appropriate methods and procedures for the measurement of impact of presence of wastewater and activated sludge on the oxygen transport (influence is expressed by the coeffi...
