sludge aerator Applications

  • Automated solutions for the aeration lagoon / pond dredging

    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.

  • Enhanced Biosolids and Bio Sludge Dewatering with Wilsa EWC

    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 solids dropping through less viscous water - Lower viscosity, reduced surface tension and increased contact angle of water - improve aeration of wastewater Installation of WILSA® ElectroWave Conditioner upstream of a belt press at a wastewater treatment plant resulted in polymer usage dropping by >50% while achieving much dryer solids.

  • Oxygen Generating Systems for Sewage Treatment

    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

  • Waste water respirometry solutions for process optimisation

    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 bacterial cell walls ceases and therefore biodegradation is significantly compromised.
