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.

Algae control

Excessive algae growth can throw even the best water treatment processes out of balance. Algae can clog intake screens, fluctuate pH levels, increase chlorine demand, and negatively affect the taste and smell of water. By blocking sunlight within water treatment tanks, you can stop algae growth, reduce chemical usage, and minimize the formation of disinfectant by-products (DBPs). Temperature is better controlled and maintenance associated with algae cleaning is simplified. The results? Better water treatment and lower operating costs.

Continuous Water Quality Monitoring

The Sorbisense method allows for continuous monitoring of water quality. Measurements can be conducted as screenings of water catchments, warnings in catchments or directly into the supply system. This method makes it possible to identify and map known problems, but also to trace the source of emergent problems.

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.
