We design and provide filtration solutions for several types of water contaminants; various filtration technologies can be applied either alone or in combination for addressing most challenging cases.
Filtration is widely used as single process or as part of pre-treatment for further operation; according to hydraulic conditions multiple vertical or horizontal vessels are used.
Based on fluid characteristics and performance results to be obtained, different media are used e.g. sand, gravel, activated carbon, nutshells, coalescing resins, etc. and vessel materials are selected accordingly.
Extensively applied for several pretreatments of different type of waters (primary, process, seawater, etc.), Charged with various granulometry sand and gravel media in atmospheric or pressure vessel arrangement
Often used as microfilters protection upstream the RO elements, they find their application for fine removal of particles
and as guard filters, with different levels of filtration, from few upto hundreds microns mesh
Manual cleaning screen filters, with internal basket typically manufactured in stainless steel material. Typically used for retaining larger suspended solids, they can be customized with different materials and filtration mesh.
These filters are widely used in many processes and have the scope to remove organics from water as well as are used
for free residual chlorine removal in disinfection processes.
Membranes are supplied in advanced separation systems when high removal capability for smallest particles (viruses, bacteria, colloids, etc.) and recovery rates are required, with final filtrated water quality at its best.
WTD offers filtering bag units complete with housing and disposal systems. Required when where solid material needs to be removed from liquids, these filters are typically used in the treatment of cooling water, wastewater, and many others.
