Sludge accumulation = 0.08 kg/person/ day.

Density of sludge = 1400 kg/m3.

Calculation:

Hence;

= 0.08 * 365 kg/person/day

= 29.2 kg / person / day

Density of sludge = 1400 kg/m3.

= 29.2 * (1000/1400).

Rate of accumulation of sludge = 20.85 litre/person/year.

= 20 liter/person/year.

Density of sludge = 1400 kg/m3.

Calculation:

Hence;

= 0.08 * 365 kg/person/day

= 29.2 kg / person / day

Density of sludge = 1400 kg/m3.

= 29.2 * (1000/1400).

Rate of accumulation of sludge = 20.85 litre/person/year.

= 20 liter/person/year.

So, 20 liter/person/year.

I think 30 is the right answer.

Pavanc said:

Yes, the correct should be 30 Lit per year.

In septic 30.

Sludge accumulation 80.

Sludge accumulation 80.

Is code recommend the value of sludge per person in the year?

I think it is 30/lit/year.

I think it is 30/lit/year.

Sludge accumulation =.08kg/person/day.

=.08*365kg/person/year

. =29.2kg/person/year

But answer says in litre.

Density of sludge=1400kg/m.m.m.

=29.2*(1000Ã·1400)

=20.85litre/person/year.

Since 1kg of sludge is not =1 lit of sludge.

=.08*365kg/person/year

. =29.2kg/person/year

But answer says in litre.

Density of sludge=1400kg/m.m.m.

=29.2*(1000Ã·1400)

=20.85litre/person/year.

Since 1kg of sludge is not =1 lit of sludge.

30 kg per person per years. Is same as 30 lit/person/years.

Because 0.08kg per person per day.

Because 0.08kg per person per day.

30 lit per person per year.
