  • Case study - Heat loss - A problem for wastewater treatment & nitrification

    Problem: Operators know aerobic and anaerobic systems need sufficient water temperature to keep microbial populations active and working. Heat loss is detrimental to effluent quality and gas production. Both systems can be negatively affected from low daily and seasonal temperatures. Unfortunately, most operators and engineers have no control over water temperature loss in their tanks and ...

  • How to Choose the Best Wastewater Treatment System for Your Plant

    For industrial companies producing wastewater as a byproduct of their process, some type of wastewater treatment system is usually necessary. Failing to properly treat your wastewater can potentially harm the environment, human health, and your process, in addition to causing your facility to incur heavy fines and possible legal action if it is being improperly discharged into a publicly owned ...

  • PeCOD Case Study – Industrial Waste Water

    Clean Harbors is an industrial wastewater treatment facility in Guelph, Ontario. The facility utilizes highly refined, chemical precipitation processes, which remove heavy metals, suspended solids, and organics to generate safe effluent for discharge into municipal sewer systems. Wastewater is treated to meet municipal discharge requirements for biochemical oxygen demand (BOD5). Since BOD is a ...

  • Performance of A-stage process treating combined municipal-industrial wastewater

    A biosorption column and a settling tank were operated for 6 months with combined municipal and industrial wastewaters (1 m3/hr) to study the effect of dissolved oxygen (DO) levels and Fe3+ dosage on removal efficiency of dissolved and suspended organics prior to biological treatment. High DO (>0.4 mg/L) were found to be detrimental for soluble chemical oxygen demand (COD) removals ...

  • Improved ammonium removal from industrial wastewater through systematic adaptation of wild type Chlorella pyrenoidosa

    A single step process is proposed for ammonium removal from nitrogenous industrial effluents, with a concomitant generation of algal biomass. A microalgal strain found in the effluent treatment plant of a fertilizer industry in Mumbai, India was systematically adapted to remove up to 700 ppm of ammoniacal nitrogen from industrial wastewater, which is nearly four times higher than the ammonium ...

  • Kinetic degradation of guar gum in oilfield wastewater by photo-Fenton process

    Guar gum is considered as a main component of oilfield wastewater. This work is intended to optimize the experimental conditions (H2O2 dosage, Fe2+ dosage, initial concentration of organics, initial pH and temperature) for the maximum oxidative degradation of guar gum by Fenton's reagent. The kinetics of guar gum removal were evaluated by means of the chemical oxygen demand ...
