THEORY:
Collection of sample is first step in estimating the composition of solid waste.
- Frequency and timing of samples collection should be carefully.
- Sample collection should extent over a full work in each season.
- It is important to note that the large the no. of samples more representative are the result.
- Location of sampling station is also important in analysis of MSW.
- Ideal location for sampling are the transfer station located all over city.
- Sample should be collected from as many different location as possible.
- Sample may also be collected from waste processing upto.
- Sample size of about 100-150 kg is considered optimum as recommended is ASTM.
- Sampling through the front and loader also reduces the change bias associated with manual collection,however large objects.
PROCEDURE:
- Prepare 200-300 kg of waste from waste pill collection vehicles.
- Mix and flatlen the waste
- Divide into 4 blocks
- Remove two blocks of waste diagonally opposite end.
- Mix and latten remaining waste.
- Divide into 4 block again.
- Reduce the waste volume by same process.
CONCLUSION:
Hence the method of solid waste sampling was studied.
