Wastewater treatment technology??? Fiber dial Filter – Filter – Filtration and S
Is the world's one of the most advanced filters, now 700 in the world have adopted the technology of sewage. Rotary filter cloth, good effect and high water quality, equipment operation and stability, has the world's only recognized water reuse certificate-Title22 certificate.
Cloth filter is mainly used for cooling circulating water, the depth of treated wastewater reuse. As cooling water, recycled water reuse filtration: water quality SS 80mg / L below the effluent SS 10mg / L. Used for advanced treatment of sewage, set in the conventional activated sludge, extended aeration method, SBR system, oxidation ditch system, trickling filter system, oxidation pond system, could be used in the following areas: removal of total suspended solids pharmaceutical dosage can be combined to remove heavy metals such as phosphorus can . Rotary filter cloth used to filter activated sludge final settling tank effluent, design quality: the influent SS: 30mg / L (maximum tolerable 80-100mg / L), effluent SS 5mg / L, the actual running water better.
Cloth filter characteristics compared with conventional filters:
(1) water quality good and stable. Rotary filter cloth filter plate is used to replace the traditional outsourcing cloth filter sand filter, filter cloth aperture small size of several microns can be retained ( m) of small particles, so the stability of both water quality and water better than the aggregate filter. The conventional filter washing ago through the issue of bad quality because of the filtering layer after washing in the washing water remaining on the water impact. Also filtered water also varies with the drag.
(2) modern design, resistance to shock loading. Rotary filter cloth filter and sedimentation tank is equivalent to a combination of function with sludge. Direct precipitation sludge particles to the large bucket-shaped bottom, do not plug the filter cloth, that is not ordinary filter: all suspended solids (SS) have to filter through. So long filter cycle, cleaning interval length, and can withstand the hydraulic loading and sludge load is higher than the conventional sand filter, suspended solids (SS) load equal to 1.5 times of ordinary sand filter, filter common filter ratio 50% increase. Therefore, the filter cloth wheel is more resistant to high concentrations of suspended matter and the impact of large particle suspensions.
(3) simple and compact equipment, ancillary equipment less, the entire filtration system and low investment. Cloth when cleaning the filter wheel can be continuously filtered. The sand could not be a continuous backwash filter, in order to ensure continuous sand filter needs to pre-set intermediate storage tank or alternate work with multiple filters. Cloth wheel using a small pump filters after liposuction to filter the water self-cleaning, eliminating the need of many of the traditional filter backwash pool, water tower, etc.. Traditional filter by backwashing strength, air and water recoil requires not only high-power pumps, blowers, there are two sets of large diameter water and gas pipe valve system. The entire system are many and complex, high investment. Automatic control system is extremely large and complex.
(4) equipment, low idle, the total installed power low. As the thin cloth, very easy to clean, very efficient cleaning, cleaning, cleaning filter disk space only equivalent to the filter plate area of 1%. Cleaning is characterized by frequent but short duration cleaning (1 / 60-120 minutes, 1 minute / second). Clean water is also less overall. Backwashing sand filter water is about 1 / 2. The traditional Filter backwash water pumps and air blowers over the equipment, automatic valves to more and larger, high power and high idle. Installed power is about sand filters of 1/10-1/15.
(5) run the automation, thus operation and maintenance simple and convenient. Filtration process controlled by computer, adjust the liposuction procedure and mud cleaning process and the process took time interval. Basic maintenance management without hand. Maintenance of the filter cloth dial a small amount. Rotary filter cloth less mechanical equipment, pumps and motors intermittent, cloth wear small cloth easy to change, if for some reason cause cloth plug, it can easily replace the filter cloth. For the sand filter, the filter plug if you need to clean large workload. And sand filtration replacement filter is very difficult.
