Primary sewage treatment essentially removes the lumps from raw sewage by settling and some of the organics by holding the waste before discharge.
Secondary treatment de-lumps and then removes organics by allowing bacteria to feed on the nutrients then removing/collecting the bacteria for disposal.
Tertiary treatment filters or chlorinates the treated waste to remove smaller particulates and bacteria.
The wastewater is first treated using secondary treatment which includes biological treatment, filtering.
The three stages of sewage treatment are primary, secondary, and tertiary treatment. Primary treatment involves physical processes to remove large solids and debris. Secondary treatment uses biological processes to break down organic matter. Tertiary treatment involves advanced processes to remove any remaining contaminants before the treated water is released back into the environment.

treatment and disposal of human waste.
It usually depends on different kinds of waste treatment plants but most of them have.
The solid wastes from a sewage treatment system are determined by the degree of treatment provided:Septic tanks: Organ sludge composed of fecal matterPrimary treatment systems: Mainly settled fecal matterSecondary treatment: Solid materials collected at the intake, aerobic sludges from aeration ponds, anaerobic sludges from digestersTertiary treatment: same as secondary treatment.
Ontario's waste goes in landfills of treatment sites.
The municipal waste treatment phase that uses aerobic bacteria to decompose and digest waste solids is called the biological process or the activated sludge process. In this process, wastewater is mixed with bacteria-rich sludge in an aerated tank, creating an oxygen-rich environment that promotes the growth of aerobic bacteria. These bacteria break down and digest the organic matter in the waste solids, resulting in the purification of the wastewater.
