KWI offers and manufactures an excellent line of filtration products from ceramic membranes, a turnkey product for revolutionizing MBR processes, to more traditional biofilter products.
The KWI biological aerated filter combines biological oxidation and SS reduction together in one structure and eliminates the need for a secondary sedimentation. This process has multiple functions such like SS, COD, BOD5 removal, and nitrification.
KWI KS Filter can be used to separate organisms in the wastewater and has high nitrogen and phosphorus removal rates.
KWI’s variable pore filter is designed for percolation filtration, and it has advantages such as filter layer small resistance, high removal rate and high filtration velocity. Our variable porosity filter has a positive flow deep bed filter designed with the theory of ‘coacervating’.
The deep-bed denitrification filter is a treatment unit which combines the functions of biological denitrification and filtration. KWI‘s deep bed denitrification filter is widely used for TN removal as secondary treatment and tertiary treatment for plants to reach strict, local standards.
The KWI V-type denitrification filter ensures water quality meets the more rigorous local government standards. This is a treatment unit which combines the functions of biological denitrification and filtration. The entire filter bed is in anoxic conditions to deoxidize nitrates to nitrogen gas.
KWI is experienced in the design and manufacturing of medium- and large-scale horizontal dual media filters such as pressurised filters, V-type filters and variable pore filters to remove total suspended solids and silt before the reverse osmosis. We are ASME and ISO certified.
KWI activated carbon filters are top-of-the-line products in the water filtration industry. Our activated carbon filters can effectively trap and absorb up to 99% suspended solids, volatile organic compounds, sediment, heavy metals, chlorine, chloramines and other particulate contaminates.
Ceramic MBR technology is not only the best choice to upgrade traditional treatment, but can replace existing polymer MBR (hollow fiber or flat sheet) as well. It can treat nitrogen, phosphate with higher processing efficiency while producing less sludge.
The CFM Systems® technology with Ceramic Flat Membranes, Ceramic Ultrafiltration, Ceramic UF and the process know-how covers a wide range of filtration applications with specific treatments and removal targets.
