LWT`s dredging systems are used for aeration lagoon / pond dredging applications. A dredging system for removal and disposal of raw sewage solids, decayed algae and microorganisms, and algae-laden sludge results in a long term solution for treatment plants. Aeration lagoon / pond dredging increases lagoon storage volume, provides improved detention time, and accommodates increased plant flow.
TDA Aerator diffuser can be used in aerobe and an-aerobe phase of (waste-) water treatment(wwtp) at all sort of industries. Ideal for biological treatment aeration and reliable for the treatment of industrial wastewater or sewage water.
the perforated surface of the membrane sleeve makes tube diffusers a perfect solution for all types of chambers and applications.
The exhalation of air through the bottom grooves decreases the depositing of activated sludge underneath the ventilation which means less cleaning...
Pulp and paper mills produce large volumes of wastewater and residual solids, presenting a number of issues in relation to pulp and paper wastewater treatment, discharge, and sludge disposal. We understand that you are seeking wastewater treatment that reliably meets permit limits, while minimizing costs, and maintaining consistent production. We will work with you to find an effective way to optimize oxygen dispersion, reduce sludge accumulation, and eliminate the need for costly dredging.
IMPROVED BIOSOLIDS/ BIO SLUDGE DEWATERING WITH WILSA® CONDITIONING
The WILSA ElectroWave™ effect can be used to condition polar fluids to alter their physical
properties, improving several chemical and physical processes.
- Reducing surface tension to improve the ability of water to repel solids - break physical / chemical emulsions
- Increasing the contact angle of water - improve coalescing of solid particulate toaccelerate phase separation
- Lowering the viscosity of water - reduce friction of flocculated...
We understand that you need to meet a rigorous set of quality standards and we are here to help you. We will partner with you to design a customized solution to meet quality requirements and keep solids in suspension, keeping your aeration basin free from sludge buildup... so you can focus on quality production.
AQQA is used in biogas plants to: separate the sludge from the liquid phase. work directly in the anaerobic sludge with methane gas aeration. work in an aerobic membrane bioreactor, that is installed after the anaerobic treatment stage.
Using Oxygen to Solve Waste Water Problems
Lack of oxygen can cause inadequate purification or even anaerobic decomposition, as well as offensive odors. Injecting oxygen into sludge beds &/or piping allows you to:
* Reduce nitrogen levels
* Meet peak O2 demands
* Have a back up to your aeration system
* Pre-purify waste water
* Control odors
* Deter corrosion damage
* Meet increased requirements regarding waste water purification
Respiration rate of activated sludge has been recognised as a key controlling element in the modelling of process control, by the International Water Association Task Group. Actual respiration rate of the sludge in the aeration tanks, as well as the endogenous and maximum respiration rates are variables that indicate the rate of BOD removal and aeration requirements. The maximum respiration rate is also closely linked to the Critical Oxygen Concentration point, that is, the point at which diffusion over the...
