In correction and post-dosing in ...


  • Advanced Enviro-Septic™ Systems Achieve Even Distribution without Pressure Dosing

    Abstract: Advanced Enviro-Septic™ Systems (AES) do not use pressure distribution. Pumps are used only if necessary to gain elevation to the treatment field. Pressure distribution has the potential to disrupt the settling of solids within the pipe. Testing has confirmed that AES achieves even distribution throughout the system naturally, through the development of a controlled bacterial ...

  • Suicides and exposure to low doses of ionising radiation

    The suicide rates in southern India are very high (Joseph et al., 2003; Aaron et al., 2004), where there are areas of high natural radiation background (UNSCEAR, 2000). It was a stable tendency towards excess of suicides among the atomic bomb survivors exposed to low doses (0?90 mGy) (Kusumi et al., 1993). It was informed about the direct dependence between the suicide rate and the residency ...

  • Excessive sulfuric acid dosing resulting in irreversible scale formation

    Many consultants in the RO water treatment industry recommend sulfuric acid dosing into the feed water as a safety measure. This case study reviews a situation where acid dosing was used with the intention of improving system performance but resulted in severe sulfate scaling. The difficulties in cleaning sulfate scales are discussed and after numerous lengthy trials, an effective cleaning ...

  • New animal feed plant relies on proven sera dosing technology

    Top animal feed is a result of the exact application of composition during the production process as well as the use of stateof-the-art technology. The correct planning of the systems engineering is as important as the experience of the staff in the production department. When the Rothkötter animal feed plant was built in Haren-Hüntel, the company relied on sera – a name widely ...

  • Damage propagation in complex biological systems following exposure to low doses of ionising radiation

    Biological organisms present hierarchical levels of organisation capable of maintaining homeostasis at low-level perturbations through intricate signalling between cells. Ionising radiation may damage DNA and other molecular components. This primary risk rises linearly with dose over a certain dose range. A second risk describes the probability of the initial DNA and other damage to propagate in ...

  • Four years experience with a new chlorine dosing regime against macrofouling

    A new method of chlorination called Pulse-Chlorination® was developed by KEMA in 1998. Pulse- Chlorination is based on the principle that mussels and clams, in general have a recovery period before full opening and start filtering after exposure to a chlorination period. The chlorination method takes advantage of this recovery time by using short successive periods of chlorination, alternating ...

  • Improvement of multi-parameter-based feed-forward coagulant dosing control systems with feed-back functionalities

    Coagulant dosing control in drinking and wastewater treatment plants (WWTPs) is often limited to flow proportional concepts. The advanced multi-parameter-based dosing control systems have significantly reduced coagulant consumption and improved outlet qualities. Due to the long retention time in separation stages, these models are mostly based on feed-forward (FF) models. This paper ...
