  • Stable Operation, High Circulation and Budget Savings

    Noerresundby Sports Center in Denmark has had DESMI pumps installed for many years. The pumps have been used for circulation of clean water in the pools. In total they have 24 DESMI pumps and recently two new pumps have been installed - one of them generates a yearly saving of approx. EUR 6,700. ”We are very pleased with our DESMI pumps, especially the two new ones, whereof the one handles ...

  • Water mixing in waste lagoons

    Man-made lagoons have been used worldwide for the treatment of domestic and industrial wastewater, it seems, forever. All waste lagoons were first designed and thoughtfully planned considering their locations, soil makeup, and waste reduction processes prior to being implemented. The biological process of organic waste reduction is always a consideration of waste lagoon designs. There are three ...

  • Ceramic Cements

    Ceramic cements help isolate, insulate and protect components in a variety of applications. Specialty ceramic cements arc directly relevant to our lives, but we rarely notice their presence. The important physical characteristics of these cements include the capacity to deal with temperature changes varying from ambient temperature up to 3000°F (1650°Q and higher, depending on the ...

  • Fuel modification by means of water. Application of Intensifier of Technological Process ABC-100

    The Intensifier of Technological Process (or ABC-100) can be successfully applied at the fuel industry for liquid hydrocarbon fuels modification by means of water. This unit can be used for production of motor and heating fuels which have improved operational and ecological characteristics. The mode of obtaining of modified liquid hydrocarbon fuel includes mixing of hydrocarbon components and the ...

  • Time-instant optimization for hybrid model predictive control of the Rhine–Meuse delta

    In order to ensure safety against high sea water levels, in many low-lying countries, water levels are maintained at certain safety levels, and dikes have been built, while large control structures have been installed that can also be adjusted dynamically after they have been constructed. Currently, these control structures are often operated purely locally, without coordination of actions being ...

  • Coagulant mixing revisited: theory and practice

    Are rapid-mixing tanks with intense mixing necessary? Intense mixing applies to the coagulation mechanism of charge-neutralization of negatively-charged particles, but this is not a common coagulation method. More common is precipitation of aluminum or iron for coagulation of particles and natural organic matter, which is often called sweep-floc coagulation. Coagulation by precipitation is ...

  • Latex Paint Mfg Treatability

    A Treatability test was conducted on August 10, 2006. This company was looking for an alternative to their current Ferric Sulfate, Lime, and DE chemical process for treating their wastewater. Our one, nonhazardous product, Floccin 1107, worked best for their particular application vs. the traditional treatment chemistry mentioned above. The initial pH of the wastewater was between 6.8 and 7.0. ...

  • Metal Polishing

    Integrated Engineers, Inc. conducted a treatability test for a facility that polishes stainless steel. We were asked to assist them in meeting their local discharge requirements as the flocculant they had been using was not working sufficiently. The initial pH of the wastewater upon arrival was 7.0. 3.0 grams of Floccin-G was used per 1000 ml jar of wastewater. After mixing for 10 minutes, the ...

  • The Potential of Solar-Powered Water Circulators to Help Solve Serious Water and Energy Problems in the U.S.

    With increasing human populations comes the corresponding increased need for improving water quality in lakes, wastewater ponds, potable water reservoirs, and other water storage facilities. Providing circulation within water reservoirs of all types has long been known to provide meaningful benefits, but the costs to achieve sufficient circulation through diffused aeration or mechanical mixers ...

  • Successful Evaluation of Ten IFAS and MMBR Facilities by Applying the Unified Model to Quantify Biofilm Surface Area Requirements for Nitrification, Determine Its Accuracy in Predicting Effluent Characteristics, and Understand the Contribution of Media...

    The performance of ten full scale wastewater treatment facilities applying IFAS and MBBR systems was evaluated using the Unified Model for Activated Sludge, IFAS and MBBR systems. At each facility, the model was applied to compute the biofilm surface area required to achieve nitrification based on the plant loading, mixed liquor temperature and aerobic mixed liquor MCRT. The effluent ammonium-N ...

  • Removal of endosulfan using aerobic mixed bacterial culture

    With the increasing use of pesticides in modern agriculture, increased evidence of their disastrous effects on the environment has been noticed. Pesticides applied in various modes and places contaminate various parts of the environment, including groundwater sources. As pesticide problems are greater in the rural areas, the authors have developed a successful low-cost technology for rural areas ...
