The precipitation of Ca3(PO4)2 scale on pipe surfaces widely occurs in numerous industrial processes. For the control of Ca3(PO4)2 scales, a novel environmentally friendly type of scale inhibitor Maleic anhydride (MA) - allypolyethoxy carboxylate (APEM) was synthesized. Structures of APEG, APEM, and MA-APEM were identified by FT-IR. MA-APEM possess excellent Ca3(PO4)2 inhibition, approximately 96.7 % at threshold dosage of 6 mg/L, and it also have superior ability to iron (III) dispersion in solutions approximately 24.3 % in the presence of MA-APEM when the dosage exceeds 6 mg/L. Inhibitor of MA-APEM can be used safely in cooling water systems.

This paper presents the results of work undertaken to develop and test contrasting data analysis approaches for the detection of bursts/leaks and other anomalies within wate r supply systems at district meter area (DMA)level. This was conducted for Yorkshire Water (YW) sample data sets from the Harrogate and Dales (H&D), Yorkshire, United Kingdom water supply network as part of Project NEPTUNE EP/E003192/1 ). A data analysissystem based on Kalman filtering and statistical approach has been developed. The system has been applied to the analysis of flow and pressure data. The system was proved for one dataset case and have shown the ability to detect anomalies in flow and pres sure patterns, by correlating with other information. It will be shown that the Kalman/statistical approach is a promising approach at detecting subtle changes and higher frequency features, it has the potential to identify precursor features and smaller l eaks and hence could be useful for monitoring the development of leaks, prior to a large volume burst event.
