Based on the data provided below, calculate the charges for disposal of the waste with and without recycling at the transfer station, and comment on these costs

            Waste generated                                             10 tonnes

            Recyclable waste                                            60 %

            Transport costs                                               $ 1 per tonne per km

            Distance to landfill                                         100 km

            Location of transfer station                            mid-way

            Cost of recovery at transfer station                $12 per tonne

            Sale value of recyclable goods                       $15 per tonne

            Tipping cost                                                    $50 per tonne

 An industrial plant intermittently discharges daily 800m3 wastewater. Its wastewater and discharge requirement characteristics are presented in the following table.

No	Parameters	Observed values
1	pH	10
3	BOD5 (mg/L)	760
4	COD (mg/L)	980
5	Suspended solids (SS) (mg/L)	620
5	TKN (Total Kjeldahl Nitrogen) (mg/L)	41
6	Total phosphorus (TP) (mg/L)	8

a) Compare the quality of this wastewater with that of domestic wastewater (the indicative values are sufficient) 

b) Suggest a treatment system for this wastewater. Explain the reasons why this treatment system has been selected.
