Water Quality Sensors
Background Water is the source of life, human life and production activities can not do without water. The quality of drinking water is closely related to human health. Water quality monitoring and control has become an important subject of modern science. The on-line water quality monitoring system can accurately, timely and comprehensively reflect the current water quality and development ...

Application of water pollution detector
Background: The (nitrate) link between agriculture and water quality is nutrient abundance - I've always thought the main issue was with fertilizers. Excessive nutrient loss often leads to eutrophication of surface waters. This condition can lead to harmful algal blooms (HAB), which produce dangerous toxins and cause a drop in dissolved oxygen, killing fish in both marine and freshwater ...

The effect of sodium thiosulfate dechlorination on fecal indicator bacteria enumeration: laboratory and field data
In microbiological water quality testing, sample dechlorination with sodium thiosulfate is recommended to ensure that results accurately reflect the water quality at sample collection. Nevertheless, monitoring institutions in low-resource settings do not always dechlorinate samples, and there is limited research describing how this practice impacts drinking water quality results. The effect ...

Research paper: Algae control with ultrasound in a WTP
Algal blooms are a form of pollution that can harm water quality and increase operating costs at treatment plants due to the presence of toxic algae. These toxins are complex, odorless, and resistant to sterilization. To meet legal requirements and optimize costs, it is essential to control algal growth in treatment plants using surface water for drinking. One solution for controlling algae is ...

High performance of nitrogen and phosphorus removal in an electrolysis-integrated biofilter
A novel electrolysis-integrated biofilter system was developed in this study to evaluate the intensified removal of nitrogen and phosphorus from contaminated water. Two laboratory-scale biofilter systems were established, one with electrolysis (E-BF) and one without electrolysis (BF) as control. The dynamics of intensified nitrogen and phosphorus removal and the changes of inflow and outflow ...

Coupling microbiological testing and sanitary surveys in drinking water quality programs: results from Capiz Province, Philippines
Developing countries often struggle to conduct laboratory-based water quality testing programs due to a lack of financial and technical resources. However, inexpensive, accurate, field-based tests are being developed which have the potential to overcome this barrier. This paper provides the results of an initiative by the Provincial Health Office in Capiz, Philippines, to conduct a first-ever, ...

Evaluation of sludge handling using acidification and sequential aluminum coagulant recovery: case study of El-Sheikh Zayed WTP
Huge amounts of water treatment sludge are wasted annually in Egypt. One common practice of sludge handling is to discharge into waterways or by disposal after drying into landfills. Currently, there is a critical need for sustainable solutions that provide environmental protection as well as benefits for water producers. Coagulant recovery is not new but is still a good solution for sludge ...

What you don`t know can hurt you
What You Don't Know Can Hurt You: The ins and outs of site inspection in a new era As NPDES permits strive to improve storm water runoff, site inspections and monitoring put an increasing demand on businesses and municipalities to evaluate and report their program performance. One of the primary goals of the permits is to gather additional data through site monitoring. The permits now are ...

Selection of food combinations to optimize survival, growth, and reproduction of the amphipod Hyalella azteca in static‐renewal, water‐only laboratory exposures
While standardized sediment toxicity testing methods have been developed for the amphipod Hyalella azteca, no standardized chronic water‐only toxicity testing methods have been established. Furthermore, optimal feeding and water quality conditions for culturing and toxicity testing with this species remained unclear. Our objective was to determine the food or combination of foods that best ...

City of Houston Total Organic Carbon - Case Study
ABSTRACT The City of Houston, Texas has been aware of the implications that current and pending regulatory standards would have on the operation of their four surface water treatment facilities. In particular, the City has closely monitored changes in regulations related to enhanced coagulation, total organic carbon (TOC) removal, and disinfection by-products (DBP) reduction. The City has, and ...

Taking Fossil Fuels to the Next Level - Standards Underpin Extraction, Processing and Distribution
To the average person, the oil and gas industry may appear simple — a matter of literally tapping into a natural resource and distributing it to customers. Of course the matter of extraction is rarely simple, and in the case of emergent hydraulic fracturing technology, it is particularly complex and capital-intensive. In fact, the world of petroleum and natural gas extraction, distribution ...

Default Guideline Values (DGVs) For Toxicants When Assessing Water Quality
Default Guidelines Values (DGVs) are developed according to risk assessment principles by using data derived from laboratory tests in clean water. The species sensitivity distribution (SSD) method is used in deriving DGVs for toxicants during water quality assessment. In circumstances where SSD is not applicable, the assessment-factor approach is used. It provides the best estimate of toxicant ...

Predictability of fouling-potential of raw water for ultrafiltration membranes
The public drinking water supply of southern Germany is characterized by a rather decentralized network. Due to the hydrogeological setting in these parts of Germany many of the small water works with an average capacity of 50 m3/h have to treat raw water extracted from karstic or cliffy aquifers. These raw waters tend to be contaminated with particles and pathogens acquired during snowmelt or ...
