Abstract:
In wastewater treatment plants, secondary biologic treatment is generally compulsory for the localities having less than 10,000 equivalent inhabitants, with a supplementary removal of nutrients if the area is a sensitive one. For the areas which are not suitable for centralized household used water collecting network individual treatment devices or collective low capacity devices are recommended. For certain settlements, for instance for the mountainous dispersed villages, or for detached individual households or farms the collective devices can not be an economic solution as involves high maintenance costs and exploiting problems due to long pipes for low flow rates. Priming is one of the starting up processes of a waste water treatment plant. This is not a very difficult process and requires no specialized staff. However, for helping the owners of a low capacity treatment plant, priming of ORM 5 type mechanical - biological equipment consisting in a tank with four compartments, designed for five equivalent inhabitants was studied inside the plant of Timisoara municipality. For the experimental tests waste water from the Timisoara city sewage network was used. This is mixed waste water resulted from faecal/domestic, industrial and rain water. The study comprised tests in unfavorable technological conditions. The conclusions of the monitoring process underline the need of control of the aeration process and the negative technological and consequently the negative economic effect of the less effective process control.
