  • Diseases That Biological Water Treatment Can Prevent

    Biological water treatment is essential because drinking contaminated water can cause illness. There are many types of contaminants, and the most common are human and animal feces, agricultural run-off, and chemicals. These contain pathogens, which cause water-borne diseases. These pathogens can quickly spread via different methods. Here are some of the most common diseases that can be ...

  • Why evaluate hydraulic fluid compatibility?

    When introducing a new control fluid to hydraulic systems, it is important to ensure that the new liquid or mixture is of equal or superior quality to the previous fluid. If the new mixture is incompatible, precipitate may form and result in an overall inferior fluid. This can speed up clogging or damage the system. When a manufacturer of construction machinery releases a new line of bulldozers ...

  • Ultrapure water – The standard for resistivity measurements of Ultrapure water - Case Study

    Abstract For years, resistivity/conductivity2 instrumentation has been used as a reliable indicator of ionic water quality, especially for ultrapure water (UPW). Traditionally, the instrumentation is procured, installed, powered up, and perhaps connected to a PLC, strip chart recorder, or a LAN. After that, the instrument and sensor receive no attention until a problem arises. Today, ...

  • Standard Chlorine of Delaware Remediation

    By designing a 70-foot deep barrier wall, Black & Veatch was able to cut off contaminant source areas from a creek near New Castle, Delaware. The groundwater treatment system that Black & Veatch designed prevents site contamination from reaching the underlying drinking water aquifer. The Standard Chlorine of Delaware Site is a 65 acre area including an abandoned chlorobenzene ...

  • Types of Environmental Standards

    Different kinds of environmental standards can serve quite different purposes in environmental policy. This note outlines these differences Ambient Standards Ambient standards set maximum allowable levels of a pollutant in the receiving medium (air, water and soil). Ambient standards can offer a simple method of establishing priorities since areas (or stream lengths) which ...


  • Emission standards versus immission standards for assessing the impact of urban drainage on ephemeral receiving water bodies

    In the past, emission standard indicators have been adopted by environmental regulation authorities in order to preserve the quality of a receiving water body. Such indicators are based on the frequency or magnitude of a polluted discharge that may be continuous or intermittent. In order to properly maintain the quality of receiving waters, the Water Framework Directive, following the basic ideas ...

  • Derivation of water quality standards for carbamazepine, metoprolol and metformin and comparison with monitoring data

    Environmental quality standards (EQSs) for three pharmaceuticals in surface water were derived: carbamazepine (epilepsy), metoprolol (heart failure) and metformin (diabetes). During the past years, these pharmaceuticals have been detected frequently in Dutch surface waters. The proposed standards are based on ecotoxicity data from national and European authorisation dossiers and additional ...

  • A Look at the Impact of Proposed Water Standard to Prevent Legionnaires` Disease

    From the standpoint of water treatment industry experts, failure to prevent legionellosis (or Legionnaires’ Disease) is the most significant water treatment problem today. Essentially every case of the disease is the result of exposure to inadequately managed building watersystems, and both utility and potable water systems can be the source of the hazard (i.e., Legionella bacteria). In ...
