    Ozone Water Treatment for Textile Wastewater Treatment Industry

    Wastewater that is discharged by dye manufacturing and textile finishing industries has become an environmental concern. The legal requirements concerning discharge of contaminated waste water are reinforced in many countries and the discharge fees are increasing. According to our experience large international clothes companies are setting a new standard of requirements, often higher than the local legislation requires.

    Waste water treatment plants Screening area: stripping

    Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. To ensure the safety of operatives in the screening building/area of waste water treatment works an H2S analyzer has been installed in the main building to complement the protection provided by individual monitors. Chromatographic measurements show that other sulfurous compounds including Methylmercaptans are present in the air in addition to H2S.

    Chemical Water Treatment for cooling and processing water

    An optimal heat transfer is the most important point in every water cooled process. Scale, corrosion and biofouling negatively affect the heat transfer. Therefore Kurita develops for cooling and process water systems customized solutions, based on the combined treatments of scale & fouling prevention, corrosion inhibition, and biocides.

    Meteorological sensors for hydro-meteorology

    Climate change makes for more extreme weather. The main reasons for this are wind and precipitation.That is why an increasing number of meteorological and hydrological monitoring networks are coming together. Global coverage with hydro-meteorological measuring technology is varied. Very old and very modern (new) measuring networks are used for climate monitoring worldwide. And there are still large gaps, for example on the oceans.

    Filtration solutions in collective irrigation communities

    The organization model of irrigation at the same level of the basin is considered one of the best ways to use efficiently the available water and the management of this resource. One of the most successful examples of this kind of Management is the Watering Communities. These communities are consortium of farmers in charge of the organization of the use of public, surface and subsurface water.

    Power-independent flow measurement with GPRS

    In a pit water purification system it was necessary to detect the discharge volumes. The operator wanted a regular and automatic transmission of readings. On the selected measurement place no mains power connection was available. Due to the risk of vandalism, it was not planned to install a switching cabinet. See the NIVUS solution for this measurement task here.

  • Trislot wedge wire screens for the water treatment industry

    In water treatment the main processes used are demineralization, softening, ion exchange, gravity and pressure filtration. Trislot wedge wire screens are used in these processes to collect or distribute the treated liquid, to retain the treatment media, to filter solids. The main advantages compared to perforated plate, wire mesh or other filtration media are: high efficiency, long service life, flexible design, low maintenance.

  • Water Disinfection for Drinking Water

    Superior Water Quality. Minimal Operating Costs. No Chemical Additives. The water treatment and water distribution up to the delivery point in the house is the responsibility of the water supplier. The owner of the real estate is responsible for sustaining the drinking water quality within the premise. REDO offers in the areas of drinking water supply solutions for the water supplier and solutions for the operators of commercial real estate. The main advantage of water disinfection from REDO: The REDO disinfectant solution in the drinking water is absolutely odourless and tasteless.

  • Force Main Systems Sulfide Odor Control with Hydrogen Peroxide

    Force main systems are typically high sulfide odor generators due to septicity conditions related to full pipe flow and a greater anaerobic slime layer (biofilm) thickness. Primary factors that influence sulfide loading generation in a force main include sewage temperature, BOD, retention time, pipe size and flow. Gaseous hydrogen sulfide (H2S) release at the force main discharge is usually the main concern related to odor and corrosion control needs; however, corrosion problems within the pipe can be of a concern (e.g. "crown cutting") at locations where air pockets can lead to concentrated H2S gas build up. Some basic considerations for assessing an appropriate sulfide odor treatment method for force main systems include: Retention time / duration of control Pump station type / cycling (e.g. vfd; start/stop, etc). Force main injection tap points, if any (e.g. air relief valves) Existence of intermediate re-lift stations or in series pump stations Manifold force main systems

  • Inspection, Monitoring and Management Technologies for Wastewater Force Main Management

    Managing wastewater force mains has historically been difficult for owners. Traditional inspection methods applied in gravity main assessment are not applicable in force mains. Given the high consequence of a force main failure, the need for an innovative approach to managing these challenging pipeline assets is necessary to minimize environmental impact and comply with regulatory requirements.

  • Inspection, Monitoring and Management Technologies for Water Transmission Main Management

    Water transmission mains are buried underground, and therefore often managed using a buried and forgotten approach. However, they are typically the most valuable group of assets utility owns.

  • Gravity Main Sulfide Odor Control with Hydrogen Peroxide

    Gravity main sewer systems include major trunk lines and the tributaries that feed them. Hydrogen sulfide (H2S) odor builds up in the collections system as the flows collect from upstream reaches and become larger, deeper and more septic (oxygen depleted) in the downstream reaches more near to the wastewater treatment plant. In general, most of the more significant hydrogen sulfide odor and corrosion control problems occur in the major trunk systems segments conveying flow to the plant. Therefore, selection of sulfide treatment for gravity systems has several options depending mainly on: Duration of control required Degree of septicity (oxygen depletion) Location of target control points or "hot spots" Location of available dosing points upstream of "hot spots" Availability of civil infrastructure and utilities Sensitivity to hazardous chemicals
