(b) Based on what you know about wastewater treatment and drinking water treatment steps, which method would you recommend modifying to reach the needed effluent concentration needed for wastewater to be directly reused?

Q: Determine the reactions at A and D. Assume the sup- ports at A and D are fixed and B and C are fixed…

A: since structure is indeterminate so we are using slope deflection method to calculate reactions

Biological Processes

Biological solid waste includes bacterial and contaminated waste produced by living individuals. Its treatment is essential to prevent the spread of any air-borne or water-borne diseases or diseases transmitted from one organism to another in a food chain. There are many benefits of the biological solid waste treatment and some of them are: the minimized quantity of waste substance, waste control, eradicating any disease-causing pathogens, generation of biogas, composting, anaerobic digestion, bio drying, mechanical biological treatment, microbial fuel cell, phytoremediation, and biofiltration. The final products of the biological solid waste treatment may be recycled to obtain organic fertilizers or disposed of in SWDS (Solid Waste Disposal Site) after proper treatment.
