Long retention time & uniform distribution of flow.
Resistant to mechanical damage.
BK-27 Bio-Growth Media is specifically designed for biological fixed film systems. Cross flow media provides a cost-effective method for reduction of organics (roughing and polishing), nitrification, denitrification, and anaerobic treatment of municipal and industrial wastewaters. The modules are fabricated from rigid, non-flammable PVC sheets, which are UV-protected and resistant to rot, fungi, bacteria, acids, and alkalis commonly present in municipal wastewater.
Combining high surface area with maximum mixing / redistribution points per unit volume of media, cross flow media facilitates superior process performance in a wide range of hydraulic wetting rates.
Each sheet in a module is completely corrugated at a 60° angle from the horizontal and assembled in a cross-corrugated pattern with adjacent sheets, creating a minimum 95% void-to-volume ratio.
This configuration provides continuous and uniform horizontal distribution of both air and water throughout the full media depth, enhancing contact between the wastewater and the media biofilm.
ADVANTAGE OF BIO GROWTH MEDIA
Folded edges at top and bottom provide critical leading to resistance to mechanical damage and erosion.
Bobkay membrane filter elements allow the mechanical compression of the filter cake after the actual filtration process. Obvious benefits compared to recessed filter elements:
Higher Throughput
Higher Dry Solid Content
Shorter Filtration Cycles
Another advantage of BOBKAY membrane filter elements becomes obvious when washing the filter cake. First the filter cake is compressed mechanically to stabilise it, and then undergoes final squeezing after the washing process has been settled, resulting in:
The Moving bed Bio Reactor includes a tank in any shape filled up with random bio media elements. The elements are specially developed material of controlled density such that they can be fluidized using an aeration device. A bio film develops on the elements, which move along with the effluent in the reactor. The movement within the reactor is generated by providing aeration with the help of diffusers placed at the bottom of the reactor. The thin bio film on the elements enables the bacteria to act upon the bio degradable matter in the effluent and reduce BOD/COD content in the presence of oxygen from the air that is used for fluidization.
Available in various shapes such as hexagonal, chevron, square, rectangular, regular hexagon.
Available with 55 or 60 angle to horizontal.
Increases capacity of clarifier due to increase in setting area.
BK-60-T Tube Settler Media utilize individual, isolated tubular channels, each sloped at 60°, to expand the settling capacity of water and wastewater clarifiers. Engineered with the individual tubes rising in the same direction to eliminate mixing currents and unstable flow patterns. Constructed of flame-resistant, self-extinguishing PVC that is also inert to naturally occurring constituents in water and wastewater.
Improve Efficiency The shape and configuration of BK-60-T module is engineered to create laminar flow for rapid settling of solids. This enhanced settling reduces chemical coagulant use and downstream filter backwash requirements. For plant design and upgrading, less settling area is needed.
