Numerical modelling: a tool for better constructed wetland design?
There is a need for a simplified computer-based design tool for subsurface flow constructed wetlands (CWs) which is based on process-based numerical models. Parameters of existing design guidelines and rules have been derived from experiments under specific conditions. Therefore designing CWs using these parameters is limited to these conditions (i.e. temperature, wastewater composition, filter ...

Particle removal in a novel sequential mechanical filter system loaded with blackwater
A novel sequential mechanical filter system was developed as an alternative primary treatment method for onsite wastewater treatment. The filter combines traditional screening with a novel type of counter-flow filter using wood-shavings as a biodegradable filter matrix. This study tested the system in a batch loading regime simulating high frequency toilet flushing using blackwater from a ...

Disinfection of an advanced primary effluent using peracetic acid or ultraviolet radiation for its reuse in public services
The disinfection of a continuous flow of an effluent from an advanced primary treatment (coagulation-flocculation-sedimentation) with or without posterior filtration, using either peracetic acid (PAA) or ultraviolet (UV) radiation was studied. We aimed to obtain bacteriological quality to comply with the microbiological standard established in the Mexican regulations for treated wastewater ...

Design configurations for commercial application of biomass carriers in small wastewater treatment plants
Introduction Moving bed type reactors are bio-film processes utilizing small, plastic biomass carriers that mix in the water. The use of biomass carriers is becoming common world-wide, for many applications, some of which are: compact low operation units, industrial wastewater roughing filters, retrofit and upgrade of municipal wastewater treatment plants. The AGARTM Process (Attached Growth ...

Hydraulic modeling - Bethel Park Municipal Authority - Case Study
Treatment plant hydraulics is often overlooked as one of the most important aspects of treatment plant design, especially in plant upgrade scenarios where retrofitting new equipment or processes into the existing treatment train will create additional hydraulic restrictions. Many existing plants already have a minimal amount of head available for passing peak flows through the system, which can ...

Oxidative degradation of COD in Petrochemical facility using Ozone-based advanced oxidation
The aim of this study was to investigate the use of ozone-based advanced oxidation processes for the oxidative destruction of COD in a petrochemical facility. Several AOP experiments were carried out in order to select and optimise the successful treatment option. A LABO3-AOP pilot unit was used where filtered wastewater (COD 1250 ppm) was circulated throughout the AOP reactor and ozone & ...

Application of high rate nitrifying trickling filters to remove low concentrations of ammonia from reclaimed municipal wastewater
The interference of ammonia with the chlorination process is a problem for many reclaimed water treatment plant operators. This paper presents the findings from a series of pilot experiments that investigated the efficacy of high flow rate nitrifying trickling filters (NTFs) for the removal of low concentrations of ammonia (0.5–3.0 mg N L−1) from reclaimed wastewater. Results showed that ...

Color removal and disinfection with UV/H2O2 system for wastewater reclamation and reuse
ABSTRACTReuse of wastewater effluents from secondary treatment processes in municipal wastewater treatment plants has been issued because of substantial volumes of relatively clean waters. The major components of criteria for wastewater reclamations are color, organic matter, and pathogens. An advanced oxidation process with low-pressure ultraviolet and hydrogen peroxide addition (UV/H2O2 system) ...

Enhancement of organic and nitrogen removal in up-flow floating filter media reactor for piggery wastewater treatment
Integrated up-flow floating media system utilised sponge cube floating bed for microbial attachment and suspended solid clarification. The first reactor was operated under anaerobic condition where high organic removal of more than 85% was reached. It was followed by anoxic/aerobic floating media reactors or chemical coagulation/air stripping units. When biological post treatment was employed, ...

The ecological filter system for treatment of decentralized wastewater
A vertical flow constructed wetland was combined with a biological aerated filter to develop an ecological filter, and to obtain the optimal operating parameters: The hydraulic loading was 1.55 m3/(m2·d), carbon–nitrogen ratio was 10, and gas–water ratio was 6. The experimental results demonstrated considerable removal efficiency of chemical oxygen demand (COD), ammonia nitrogen (NH4+-N), ...

A novel electrospun polyurethane nanofibre membrane – production parameters and suitability for wastewater (WW) treatment
The aim of this study was to investigate the suitability of a novel electrospun polyurethane nanofibre material for water-treatment purposes. Bacterial removal efficiency was tested in the laboratory by filtering artificial water spiked with Escherichia coli through a 0.25 µm nanofibre membrane. The results were compared with those obtained using a commercial microfiltration material ...
