The concentrations of NH4, PO4, TP, and chemical oxygen demand (COD), were measured using Merck cell test kits according to the manufacturer instructions. Mg2+ was analysed using an atomic absorption spectrophotometer (Analyst 800, Perkin Elmer Ltd, Beaconsfield, UK) equipped with an air/acetylene burner system. The pH was measured with a Fisherbrand hydrous 300 pH meter (Fisher Scientific, Loughborough, UK) immediately after sampling. Values presented details of the mean and standard deviation of duplicate or triplicate tests.
Cell test kits
Manufactured by Merck Group
Cell test kits are laboratory equipment designed to facilitate the analysis and examination of cellular samples. These kits provide the necessary tools and reagents for various cell-based assays, enabling researchers and scientists to study cell properties, behavior, and responses to different stimuli.

Samples were filtered (0.45 µm syringe filters -VWR) and pH recorded (Jenway 3540, UK). Mixed liquor suspended solids were analysed according to standard methods (Eaton, 2005) . Merck cell test kits were used to determine the concentrations of NO 2 --N, NO 3 --N, NH 4 + -N, SO 4 2-and soluble chemical oxygen demand (sCOD) following the manufacturer's instructions. Thiocyanate and phenol were determined colorimetrically at a wavelength of 465 and 510 nm, respectively, using a Jenway 6300 spectrophotometer (Staffordshire, UK). Thiocyanate was determined by a method based upon the reaction of thiocyanate with iron (III) to produce an orange-red colour based on a red complex (The Institution of Gas Engineers, 1971) while phenol was determined using 4-aminoantipyrene based upon ISO 6439:1990 (ISO, 1990).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
