Among them: a quantum average sediment of one person in one day, took 0.7 - 0.8 liters.
T - 2 times the time between taking sediment from the tank (taken by 1 / 2nam = 180 days)
W1 - humidity of fresh sediment entering the tank, usually taken by 95%.
W2 - the moisture content of fermented sediment, decaying as the pool, taking in 90%.
B - the reduction coefficient to mention the volume of sediment, fermented rotten, taken by 0.70 (down 30%).
c - coefficient of 1 part residue left fermented in tanks for septic accelerated process, usually taken with a 1.2 (20% left).
N - number of people who pool serves (2,501 people).
the volume of the water:
Wn = (2,501 x 20 x 1) x 1.2 / 1.000 = 60 m3
volume parts sludge:
W b = = 132 m3
tank capacity septic:
Wth = Wn + Wb = 60 + 132 = 192 m3
2 septic tanks Select size: L x B x H = 6m x 4m x 4m
