30 kg per person per years. Is same as 30 lit/person/years.
Because 0.08kg per person per day.

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*(1000รท1400)
=20.85litre/person/year.

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

Narendra said: (May 25, 2018)  
Is code recommend the value of sludge per person in the year?

I think it is 30/lit/year.

Suresh said: (Mar 1, 2019)  
In septic 30.

Sludge accumulation 80.

Pavanc said: (Apr 26, 2020)  
Yes, the correct should be 30 Lit per year.

Shubham Meena said: (Dec 3, 2020)

Mjm said: (Jul 1, 2021)  
I think the correct answer to be 30 ltrs.

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.
So, 20 liter/person/year.

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.
