A review on the essential role of substrate on aerobic granulation

Aerobic granulation is a selection pressure-driven cell-to-cell immobilisation process. So far, the essential role of substrates on aerobic granulation has not been well clarified. This paper reviews current studies about aerobic granulation with different substrates. Although substrates do not exert a major selection pressure on aerobic granulation, they will select substrate-related ...

Porous structure and spatial characteristics of aerobic granules

Cryosectioned granules were observed in microstructure, Extracellur Polymeric Substances (EPS) and metal distribution. Aerobic granules composed of pores and channels that were not plugged by EPS, with rather open structure. Microorganisms proliferated mainly on the surface of granule and on the wall of channels, carbohydrate EPS mainly distributed on the surface of granules, and protein EPS ...

Effect of substrate feeding on viscosity evolution of anaerobic granular sludges

This work aims to describe the effect of the feeding regime of anaerobic activity tests on the limit viscosity (μlim) evolution of the granules. Batch experiments were performed with 3 different sources of substrate: acetate, peptone, and glucose. Despite, the substrate origin was shown to affect the μlim evolution of granules, no clear relationship was found between the μlim evolution, type of ...

Size-dependent microbial substrate uptake kinetics for aerobic granules

Biodegradation kinetics of aerobic granules determined by indirect method of resporimetric technique showed that it followed Monod kinetics, and the kinetic behaviour was size-dependent. It was further demonstrated that biodegradation kinetics was a surface reaction associated phenomenon. It shows that the affinity coefficient of biomass to substrate in terms of qmax/Ks ratio (specific maximum ...

Investigating the influence of elongated anaerobic feeding strategy on aerobic sludge granulation and characteristics in sequencing batch reactor

In this research, two sequencing batch reactors (R1 and R2) were operated with different feeding strategies to investigate the effects of elongated anaerobic feeding mode on the granulation process. For this purpose, R1 was operated in a short-feed strategy (5 min) as a reference, whereas an extended anaerobic feeding of 85 min was applied in R2. Results showed that aerobic granules formed in ...

Filtration media: Shapes and manufacturing processes

The shape of the filtration media and the production process directly affect the absorption capacity of the granulate and consequently the efficiency of filtration. Granules in the shape of a pellet (cylinder) do not facilitate such a high degree of compaction as spherical granules, so that the passage of the air flow becomes easier, as preferential streaming is avoided. This implies less loss ...

Towards eco-efficiency: granulated nickel slag's transformation into a product

The granulated nickel slag is the biggest unexploited solid side stream formed in the area of the Harjavalta industrial ecopark in south-west Finland. Nowadays one-quarter of the granulated nickel slag is utilised in the sand blasting and roofing felt industries and three-quarters are still dumped in landfills. At the moment the main obstacles to a wider utilisation of granulated nickel slag are ...

Strength characteristics of aerobic granular sludge

Aerobic granular sludge has a number of advantages over conventional activated sludge flocs, such as cohesive and strong matrix, fast settling characteristic, high biomass retention and ability to withstand high organic loadings, all aspects leading towards a compact reactor system. Still there are very few studies on the strength of aerobic granules. A procedure that has been used previously for ...

Dynamic changes in microbial diversity of aerobic granules

The bacterial diversity and their population changes were investigated in acetate-fed aerobic granules cultivated in two Sequencing Batch Reactors (SBRs), A and B. The top nine dominant bacteria were isolated, and their growths were tracked in another two SBRs (C and D) which were cultivating granules without selection pressures. The nine bacterial population in C and D were compared to the ...

Selection pressure theory for aerobic granulation – an overview

Aerobic granulation technology is an improvement over conventional activated sludge process, where cell-to-cell interactions lead to the formation of stable granules with excellent settleability. Selection pressures are the factors that can strongly influence the formation and growth of aerobic granules. Settling time and the volume exchange ratio (VER) will decide how long the bioparticles ...

Analysis of wear reason of double roller granulator

1. The roll skin of the double roller granulator is affected by the hardness, size and shape of the processed material. Too hard, too large or too irregular materials are easy to cause uneven wear of roller skin. 2. The wear of the double roller granulator, the surface shape, specification and size of the roller and the operation conditions will affect the fertilizer granulator. 3. The wear of ...

pH variation and influence in an autotrophic nitrogen removing biofilm system using an efficient numerical solution strategy

A pH simulator consisting of an efficient numerical solver of a system of nine nonlinear equations was constructed and implemented in the modeling software MATLAB. The pH simulator was integrated in a granular biofilm model and used to simulate the pH profiles within granules performing the nitritation–anammox process for a range of operating points. The simulation results showed that pH ...

Effect of extended feeding time on aerobic granulation in SBR

Two different feeding lengths were applied to control the granule size. It was found that the size of granules was considerably controlled in R2 (60 min for feeding). However, the settleability in R2 was not as good as that in R1 (12 min for feeding). However, this approach of controlling the granule size also loosens the structure concerning on the difference between SVI5 and SVI30, which might ...

Coating of Plastic Granules - case study

In order to increase the production output of extruders and injection moulding machines, the flow and processing characteristics of plastic granules have to be modified. Especially for polyamides (PA) and polystyrene (PS) this occurs by means of powdering (coating) with powder additives. In doing so, two different methods are common. The pure dry mixing of plastic granules with the powder ...
