Grey water treatment design

Hello RMV, i have a grey water treatment project, what i need is :

1- determine the inflow water parameter

2-designing a process and a method used for preliminary treatment unit ( explained and designed in details )

3-designing a process and method used to design primary treatment ( coagulation-flocculation )

4-designing a process and method used to design primary treatment ( secondary ) ( and estimating the amount of biosolids from the settling tank during the process )

my wasted water is ablution water (250 gallons per day ) and i want to treat the water to use it for aggregation 

i have uploaded two pictures showing the ablution water quality parameters and the other two show the aggregation water limits

i need it to be done within 3 days.
