There are several types of waste, municipal waste (household waste) that a liquid is one of the environmental problems that
are very well disturb the existing watercourse. It is because of some content in the waste, including chemical and biological
These residues can in principle be broken down by itself in nature, but it will take a long time to sterilization.
To accelerate the neutralization of the waste disposal system may be necessary to decipher the biological and chemical
substances in water that can be accepted by nature without harming fish or plants. The process usually takes several years,
the nature, but with this system, it takes only 12 to 24 hours.
Usually consists facility of multiple processors as follows:
1. The first phase of initial treatment
The screen with a bar mounted in the tank that acts as a filter for processing the first set or the float and fixed objects
with a diameter that can be solved. Excrement of the cleaning process and the decision manually.
2. The first phase of treatment
Processing plants in the initial form of wastewater treatment is the presence, acts as a floating bath oil or grease
receiver. The bathroom is necessary because the waste can be processed waste will be maid in the kitchen. After passing the
floating devices, the devices must be the primary Clarifier tanks precipitated solid waste.
3. The second phase of treatment
Basic process of waste is in this second phase of experimentation in the biological treatment process that the unit rotating
biological contractor (RBC). The RBC is the degradation of pollutants, microorganisms that develop in the disk rotating disk
(rotor disk) micro-organisms grow and unite to form biomass disc rotor / biofilm.
Gravity drainage of waste produced by the high water level in zone 4 below the water level in 3, 2 and 1 The effluent will be
treated by a biomass which grows on the band in each subsequent disc areas zone 1-4. Biomass grown in the rotor disc will be
in contact with oxygen in the air at the time of the water due to the transfer of oxygen. The rapid growth of gangs in the
biomass produced in areas with hard and progressive reduction in the next area. Physics of biomass in Zone 1 will be more
daring with the son of a dark brown again. While the region is the will of steel, with light brown or yellowish.
Four waste water is very clear the contents of the BOD, and?Because the material of the suspension. In this area most of the
water recycled in the tank as soon as the rain and partly transferred to a final resolution goals.
Recycling is to provide direct access to the water content of the BOD concentration of oxygen is low, but high-NOK to assist
the weight of new units for wastewater treatment.
4. The last phase of treatment
The plant is the last unit of the final solution Clarifier to reduce suspended solids and biomass pellet coat.
