Enhancement of settling tank capacity using a new type of tube settler
The effectiveness of a newly developed lamellar settler was confirmed by onsite experiments. The device had inclined parallel plates arranged in a vertical direction in a settling tank. This vertical arrangement method enables many more plates to be set compared to the conventional horizontal arrangement. As an original and distinctive innovation, both the right and left edges of the plates were ...

Dynamic one-dimensional modeling of secondary settling tanks and system robustness evaluation
One-dimensional secondary settling tank models are widely used in current engineering practice for design and optimization, and usually can be expressed as a nonlinear hyperbolic or nonlinear strongly degenerate parabolic partial differential equation (PDE). Reliable numerical methods are needed to produce approximate solutions that converge to the exact analytical solutions. In this study, we ...

Exploration/Mining - Case Study
The overflow of the settling tank is pumped to Sofi Filter via a centrifugal pump. Due to the filter's cross-flow design, part of the feed flows through the filter element and part returns to the process. In this application Sofi Filter is equipped with a 10 um metal wire mesh element. The filtrate from Sofi Filter can be drained or reused. Sofi Filter reduces the amount of water in the settling ...

On time discretizations for the simulation of the batch settling–compression process in one dimension
The main purpose of the recently introduced Bürger–Diehl simulation model for secondary settling tanks was to resolve spatial discretization problems when both hindered settling and the phenomena of compression and dispersion are included. Straightforward time integration unfortunately means long computational times. The next step in the development is to introduce and investigate ...

Concentration-driven models revisited: towards a unified framework to model settling tanks in water resource recovery facilities
A new perspective on the modelling of settling behaviour in water resource recovery facilities is introduced. The ultimate goal is to describe in a unified way the processes taking place both in primary settling tanks (PSTs) and secondary settling tanks (SSTs) for a more detailed operation and control. First, experimental evidence is provided, pointing out distributed particle properties ...

A consistent modelling methodology for secondary settling tanks: a reliable numerical method
The consistent modelling methodology for secondary settling tanks (SSTs) leads to a partial differential equation (PDE) of nonlinear convection–diffusion type as a one-dimensional model for the solids concentration as a function of depth and time. This PDE includes a flux that depends discontinuously on spatial position modelling hindered settling and bulk flows, a singular source term ...

Advanced algae technology: The use of Ultra sonic technology for control of algae growth in an open balance tank
Abstract One of the many challenges faced by Wastewater Treatment Plants (WWTPs) is the control of algae blooms. High algae concentrations create problems for process performance and increase operating expenditure for cleaning and maintenance activities. Algae blooms can contribute to fooling of filtration equipment aa well as foaming events on clarifiers and settling tanks. High parameter ...

The role and control of sludge age in biological nutrient removal activated sludge systems
The sludge age is the most fundamental and important parameter in the design, operation and control of biological nutrient removal (BNR) activated sludge (AS) systems. Generally, the better the effluent and waste sludge quality required from the system, the longer the sludge age, the larger the biological reactor and the more wastewater characteristics need to be known. Controlling the reactor ...

Innovative use of lamella clarifiers for central stormwater treatment in separate sewer systems
Lamella settlers have been used in the past few years for the sedimentation of particles in wastewater and stormwater applications. A new and very innovative approach for the treatment of stormwater flows is proposed which extends the portfolio of solutions beyond traditional settling tanks. Surface runoff is stored in a sewer or a basin and finally treated in a small but continuously operated ...

Glass Recycling Facility Wastewater Treatment Case Study
Recycling Wastewater Treatment Success Stories Glass Recycling Facility Wastewater Treatment A glass recycling facility needed a means to increase the size of their settled solids so they could be dewatered in their filter press. The fine solids caused carry through of the press (cloudy filtrate) and did not dewater well. The samples tested were from the initial ...
