Sewage treatment for hospital

Sewage treatment for hospital

Purifier preliminary:

In the refined preliminary large objects like leaves, trees, etc. خردهشیشه a shell, egg, sand and gravel, and substances such as these of the sewer will be removed. Solids coarse by آشغالگیر taken into account, and glass, shell eggs, sand, and sand and... in دانهگیر isolation. This material, in the absence of isolation and the entrance to the units next تصفیهخانه., the problems of operation and maintenance regime ), for example, create سائیدگی in pumps and other mechanical equipment, etc. create congestion in the system plumbing (.

Filtration primary

Refined the initial time. sewer for entry to units biological filtration ready.

Purpose purification the initial removal of suspended solids visible تهنشینی and reliable fluidization to help the force of gravity )that in the pond تهنشینی the primary researcher is( and uniform storage.

Secondary filtration

The secondary filtration involves the biodegradation of organic compounds in Solution., the removal of nutrients )of nitrogen and phosphorus ( and disinfection effluent. The removal of nutrients, usually by the processes of biological. Nitrogen by processes نیتریفیکاسیون - دنیتریفیکاسیون as nitrogen gas from the wastewater is removed. Processes نیتریفیکاسیون and دنیتریفیکاسیون, respectively, requires conditions on the Aerobic presence of O2 and آنوکسیک)in the absence of O2 and presence of compounds اکسیدشده such as nitrate and sulfate are. The removal of biological phosphorus also requires conditions on anaerobic exercise )in the absence of O2, and combinations اکسیدشده(Aerobic. After biological filtration, etc. microorganisms and other solids as sludge in the pond تهنشینی secondary تهنشین. In some methods of biological filtration, including the process of activated sludge, the sludge, in order to accelerate the action of filtration, to filtration units, the biological return is given and the other part as a sludge management filtration and disposal cycles. Disinfection, eliminate microorganisms pathogen. For disinfection, the effluent can be from gas chlorine, sodium hypochlorite and calcium, دیاکسید chlorine, ozone, etc. UV ماوراءبنفش and... used. In cases where the effluent تصفیهخانه the sewer, the hospital entered surface waters. disinfection effluent of far more importance.

Advanced water filtration or update:

As previously said, affirms a lot about the removal of microorganisms pathogen and microbial contamination from sewage, hospital there. Cease help of parasites, etc. 95 - 90% bacteria, and the percentage of most of the viruses in the tank تهنشینی primary and secondary sediment), and from the flow of effluent removal. therefore, effluent from the stage filtration of the secondary is almost free of parasites, and contains some bacteria and virus will be. The concentration of suspended solids in wastewater, secondary, about 20 mg/L, which is the amount of suspended material inhibits the disinfection effective wastewater treatment. thus the effluent of the secondary before disinfection have entered the stage of purification of additional the direction of reduce the concentration of suspended solids. To this end, usually from the filtration صافسازی proprioception is used. Filtration, deepthroat, able is the concentration of suspended solids in the effluent to less than 10 mg/L decrease.

Company engineers پالود the industry of the righteous is proud to announce that utilizes the experiences and knowledge of the day their engineers ready providing consulting, design, construction and implementation of water purification systems and sewage, especially sewage of hospital.
