Water treatment
Wastewater treatment involves a multi-step process to clean sewage and remove contaminants before water is disposed or reused. Sewage from homes and industries contains human waste, chemicals, bacteria and other pollutants. It is carried through pipes to a treatment plant where it passes through screens to remove large solid objects, settles in tanks to separate out sand, grit and solids, and is treated with oxygen and bacteria to break down organic matter. The cleaned water is then disinfected and released while solid waste is further dewatered and dried. Proper wastewater treatment is needed to prevent water pollution and disease.
Raw water treatment
The document describes the process of raw water treatment and sewage treatment. For raw water treatment, a combination of Dynadisc and Dynasand filters are used to filter and chemically treat raw water to provide ultrapure water. The sewage treatment process involves 4 stages - screening to remove large solid objects, primary treatment to separate solids from wastewater using settlement tanks, secondary treatment using aeration lanes to break down remaining solids with bacteria, and final treatment including additional settlement, sand filtering, and further polishing to produce almost pure water.
Water
This document discusses water in its three forms - solid, liquid, and gas. It provides details on the water cycle including evaporation, condensation, and precipitation. It notes that while the earth is mostly covered in water, most is saltwater and unavailable for human use. Freshwater is limited, with less than 1% available for drinking. The document outlines water usage and conservation efforts needed given rising demand and threats of pollution and drought. It promotes rainwater harvesting as a way to supplement water supplies.
Water Treatment Process (Screening)
The document discusses the water treatment process, which involves removing pollutants from raw water through screening and filtering to produce safe water for human use. The screening process removes wood chips, leaves, and other floating impurities. This creates a more compact suspended material and allows the water to flow into chambers where settled material collects on the bottom. Screening restricts solid waste from entering the water treatment plant and prevents equipment damage while preparing the water for subsequent treatment steps.
Water purification methods
This document discusses various methods of water purification and identifies the most appropriate methods based on different situations. It identifies boiling, filtering, distilling, and chlorination as common purification methods. Distilling is considered the most effective as it removes the widest range of contaminants, but has limitations as it removes minerals. The appropriate method depends on factors like local water quality, cost, and performance of the system. Groups will present creative ways to purify water and discuss limitations of distilling.
Wastewater Story
This document discusses wastewater, its sources and composition. It describes the wastewater treatment process which includes collection, screening, primary treatment to remove solids, secondary treatment using bacteria, disinfection, and final disposal. It also discusses stormwater drainage challenges during floods and better sanitation practices like vermicomposting toilets and septic tanks to treat sewage. The overall wastewater treatment process aims to remove contaminants and make water reusable or safe for release into water bodies.
