A new online monitoring and management system for accidental pollution events developed for the regional water basin in Ningbo, China
Due to urgency of the accidental pollution events (APE) on one side and the variability in water quality data on the other side, a new online monitoring and management system (OMMS) was developed for the purpose of sustainable water quality management and human health protection as well. The Biological Early Warning System (BEWS) based on the behavioral responses (behavior strength) of medaka ...

TOC analyzer for airports
During winter, de-icing processes at airports necessitate storm water and de-icing water management. Especially due to adhesive (sticky) substances, strongly fluctuating concentrations and a lot of chemicals, the monitoring systems itself must be tailor-made to fight this water analysis challenge. LAR 's QuickTOCairport is an application-specific online total organic carbon (TOC) analyzer that ...

Water and Wastewater Chemical Management - Case study
Objective Our MCE analytics platform uses existing chemical tank level data for chemical management and monitoring on water and wastewater sites. By monitoring the rates of change in tank levels, we automatically work out if tanks are emptying or being filled. So, we can calculate chemical consumption and applied dose rates using existing telemetry or SCADA data. This is up and running on more ...

Spatial and temporal variation of water quality of a segment of Marikina River using multivariate statistical methods
Payatas landfill in Quezon City, Philippines, releases leachate to the Marikina River through a creek. Multivariate statistical techniques were applied to study temporal and spatial variations in water quality of a segment of the Marikina River. The data set included 12 physico-chemical parameters for five monitoring stations over a year. Cluster analysis grouped the monitoring stations into ...

State of the art treatment for Arsenic, color, and Hydrogen Sulfide - Case Study
New Arsenic Regulations How meaningful to the average water customer are µg/l or parts per billion? Not very. How about the word “arsenic”? That will ring some bells as the mystery novel poison-of-choice. But with new, lower EPA arsenic standard of 10 ppb that went into effect Jan. 16, cities with arsenic problems are required to inform customers in writing of non-compliance, ...
