A rural village with 70 people equivalent(p.e.) is nearby a 30 cm deep, 1 m wide pristine river flowing at a speed of 1 cm/s. One p.e. corresponds to 250 L of wastewater per day. BOD decays with a rate of 0.25 day-1. Determine the minimum dissolved oxygen in the river if it receive sun treated wastewater (BOD5 is 200 mg/L)from this community. Assume saturated oxygen is 9 mg/Land no oxygen deficit initially (i.e, at mixing point)
