wastewater, (van Larsdrecht, 2005). The excess content of ,phosphorus, in receiving waters usually leads to extensive algal growth (eutrophication). Controlling ,phosphorus, discharge from municipal and industrial ,wastewater, treatment plants is a key factor in preventing eutrophication of surface waters (Department of Natural Science, 2006).

Removal of copper ions from acid mine drainage wastewater ...

A factorial experimental design method was used to examine the "Cu2+" removal ,from acid mine drainage wastewater, by ion exchange technique. Ion Exchange technique is preferred because of reduced sludge ,generation, compared to conventional treatment techniques and better decontamination efficiency from highly diluted solutions. Factorial design of experiments is employed to study the …

Evaluation of the role of inherent Ca2+ in phosphorus ...

Wastewater containing phosphorus, (25–100 mg P/L) was prepared using tap water or deionized water and KH 2 PO 4 as ,phosphorus, source and did not contain organics. This means that ‘experimental artificial’ ,wastewater, contained only the inorganic part of the ,wastewater, and the organics-free environment was used to investigate the role of inherent Ca 2+ in ,phosphorus, removal.

Evaluation of the role of inherent Ca2+ in phosphorus ...

These results imply that Ca-P precipitates can contribute to the removal of ,phosphorus, in artificial ,wastewater, prepared with tap water, suggesting that inherent Ca 2+ may become a scavenger of ,phosphorus, in ,wastewater,. The removal of ,phosphorus, is a fast process involving the complex interactions of phosphate and Ca 2+ under alkaline conditions. The decrease of ,phosphorus, …

pH, is a scale of measurement expressing the, acidity, or, alkalinity, of the, wastewater., In the, pH, scale, a value below 7 shows that a, wastewater, is, acidic,, a value of 7 is neutral, and values higher than 7 are alkaline. The pH values are logarithmic, meaning a pH of 6 is 10 times more, acidic, than a pH of 7.

1 mg/L alkalinity as CaCO3 = 1.2192 mg/L alkalinity as HCO3 – Why is pH Important? If the pH of water is too high or too low, the aquatic organisms living within it will die. pH can also affect the solubility and toxicity of chemicals and heavy metals in the water ¹².

Chemical Analyser and Online Monitoring of Potable Water

Alkalinity, is consumed in the conversion of Ammonia/Ammonium to Nitrate during the nitrification stage of treatment. Because most, waste waters contain, eco harmful, Phosphates, it is common also to remove, phosphorus, by use of Ferric or Alum salts. These solutions are highly, acidic, and hence can strip the natural, Alkalinity, from the, waste, samples.
