Liquid media waste water treatment equipment
A revolution of the drainage processing!
What is a liquid media?
In the drainage processing, it is a slightly porous film separating sludge by a principle of "the filtration".
Increase of the throughput is possible by installing a liquid media in a drainage processing process without using the sedimantation tank.
Characteristic of the liquid media
- The liquid media liquid waste treatment does not use sedimantation tank.
Therefore the state of the processing water is good even if Baru King who is the biggest problems of the conventional activated sludge treatment occurs.
In addition, separating it into solid and liquid performs it surely, and there is no outflow of the sludge.
(even if a filamentous fungus occurs, there is no problem.)
※Baru King…The phenomenon that activated sludge expands, and becomes hard to subside. - Because I can use activated sludge density to 20,000 mg/l, processing capacity of conventional 3-5 times is provided.
(1.5 kg of BOD volume load, BOD/m3, day)
I am very strong in a load change, and, with compact setting space, stable processing water is provided.
(ability level BOD5mg/l, less than SS1mg/l) - I can reuse the processing water for trivial routine duties water, melting snow use.
- Gravity filtration is possible, and there are few power costs, and maintenance is easy by energy saving driving.
- Because the whole setting is simple, and there are few supplementary planes, construction is easy, and construction is possible at low cost on a short deadline.
Setting example of the liquid media unit
The liquid media unit arranges necessary number in the water tanks such as products made in RC and installs it.
As for the unit, a film case receiving a tube pulling out processing water from the film cartridge which put a slightly porous film on both sides of the filter plate and the inside, a film cartridge of the multi-number of sheets is comprised of aeration equipment of the lower part and a case to disperse more.
I can take out one piece of film cartridge and can perform check, exchange easily.
In addition, I can perform a boost and the suspension at the time of the maintenance easily if I install an optional guide rail at the time of construction.
