A series of other observations further underscore the importance of maintaining the needed microbial population. Likewise, the final EtS peak around the end of May depicted in period G in Figure 3 correlates well with the preceding 3-week period that had a reduced SRT of 20 days. Conclusively, an SRT of roughly 30 days seems to be a prerequisite for appropriate EtS biodegradation.

This is one of the same order of magnitude as the SRT of approximately 3 weeks for almost complete EtS biodegradation that was reported in Ref. The short-term EtS peak in the final effluent indicated by E in Figure 3 has not yet been discussed. This peak emphasizes again the complexity inherent in biological wastewater treatment. This short-term reduced EtS removal correlates well with a shock load of aniline that reached this WWTP, which seems to have affected the EtS breakdown at that moment. A possible cause for the observed EtS set-ups indicated with F in Figure 3 is, however, not known — once more highlighting the inherent complexity of wastewater treatment based on biological processes.

Before the removal of PVA will be discussed, it must be mentioned that after the first period A in Figure 3 of low EtS removal due to the reduced SRT, the standard applied phosphate dosing in the feed data depicted in light blue in Figure 4 was stopped, because phosphorus-containing molecules were found at that time in the final effluent — indicating reduced biological treatment efficiency. Because of the low permitted concentration for discharge of total phosphorus from the facility, the phosphate dosing was stopped at that time.

Poly-vinyl alcohol PVA , concentration in the feed and final effluent, together with its removal efficiency. One explanation for this can be found in the too-short SRT in these two periods 10 and 15 days, respectively , which caused the low EtS-removal efficiency, as discussed earlier. The observed variation in PVA removal could be attributed to possible small changes in the structural characteristics of the PVA, which is known to affect the activity of several PVA-degrading enzymes, and hence the rate and extent of polymer biodegradation. Then, around the beginning of March , the PVA in the final effluent fell from 2—10 ppm to a baseline of 0 ppm see Figure 5 , indicating complete removal of the PVA.

It is known that a P-to-C ratio in the feed that is too low can cause loss of treatment efficiency with activated sludge processes. It appears that the amount of P in the feed before March was not enough to attain complete PVA removal, whereas complete EtS removal was still achieved with the lower-P system condition. This period of temporarily reduced PVA removal correlates well with the temporary cessation of phosphate dosing that had been initiated about 20 days before.


Something had caused a short-term effect on the biological working of the activated sludge, as exemplified by the lower PVA- and EtS-removal rates. It is important for facility owners and operators throughout the chemical process industries to recognize that in addition to degradation generalists, degradation specialists are needed to design systems that will reliably biodegrade hard-to-degrade pollutants.

Biological wastewater treatment is an inherently complex process. Factors such as ensuring a sufficient long sludge SRT age and an abundance of nutrients such as P are prerequisites to augment the biological removal of specific components. Daigger, T. An, L. Conn, E. Gray, N.

Lucas, N. Halter C. Bart Peeters is a manufacturing technologist at Monsanto Europe N. Since then, he has been working at the environmental department of Monsanto with particular responsibilities in improving the wastewater treatment plant and the combined sludge centrifuge-dryer installation. He is the author of 20 papers in scientific journals, technical magazines and international conferences.

In his current role, he is responsible for analytical method development, troubleshooting and method validation for the different production sites at the Monsanto Antwerp location. He received his B.

Ultra filtration UF membrane removes almost all suspended matter and also dissolved organic compounds depending on their molecular mass and on the molecular mass cut-off of the membrane. It is also used as pre-treatment process for Reverse Osmosis System as it reduces the SDI and leads to longer membrane life. We provide Reverse Osmosis Plants Designed on latest technology for wide applications like drinking , Process water in industries , Boiler feed water Etc.

We Design and Supply Industrial Water Softeners where calcium, magnesium ions are exchanged for sodium ions.

These are manually and automatically operated and designed to suit the requirement of process water in industries such as textile mills, beverage manufacture, laundry and air conditioning plants, boiler feed etc. This unit produces treated water with low residual hardness which is optimum for industrial use as per requirement. After treatment, the treated water can be reused for gardening or can be disposed off. Further, the packaged sewage treatment plant uses all the treatments of aerobic system. It includes:. DM plants are used to remove TDS present in water. F, Hasselblad, S. Chen, G.
