Wastewater treatment
Ampac USA advances wastewater treatment engineering beyond conventional, passive systems by using the state-of-the-art in physical, chemical and biological technologies. Through automation, constant monitoring and close control of key steps, the treatment process achieves significant reduction in retention time (settling, reaction, separation), space requirements, operational attention and ultimately, cost.
Physical and biological treatment of sewage lecture 1 of 2
Sewage treatment involves three main phases - pre-treatment, primary treatment, and secondary treatment. Pre-treatment screens out large solids. Primary treatment removes most solids but not dissolved organics, using sedimentation. Secondary treatment uses microorganisms to break down organics into simple compounds and uses sunlight to destroy pathogens, producing effluent safe for discharge. The sludge byproduct is further treated and can be used as fertilizer or disposed of through other methods.
Design of 210 Mld Sewage Treatment Plant
This document provides details on the design of a 210 million liter per day sewage treatment plant. It discusses the need for the plant to treat sewage and prevent pollution. It then describes the three main stages of sewage treatment - primary, secondary, and tertiary treatment. Primary treatment involves removing solids and debris. Secondary treatment uses microorganisms to break down dissolved organic matter. Tertiary treatment further polishes the water with methods like filtration and chlorination before discharge.
Microbiology of sewage and sewage treatment
Sewage or wastewater contains water and solids separated from various sources like domestic, industrial, and stormwater runoff. It contains pathogens and organic material. Treatment aims to remove solids, reduce biochemical oxygen demand (BOD), and eliminate pathogens through primary, secondary, and sometimes tertiary processes. Primary treatment removes 50% of solids and 25% of BOD through settling. Secondary treatment further reduces BOD through microbial degradation. Sludge from primary treatment is anaerobically digested by microbes to produce methane and reduce pathogens before disposal or reuse. Disinfection with chemicals or UV light is sometimes applied before releasing the treated water.

this presentation is about the reuse of treated wastewater.Different application and technologies involved. I have also put four case studies taken from some journals mentioned.
Sewage Treatment Plant Treatment For Wastewater
The document describes the process of a sewage treatment plant. It goes through primary treatment which removes solids, secondary treatment using bacteria to break down organic matter, and tertiary treatment using physio-chemical processes to refine the water. The sludge from treatment receives further processing like incineration or composting. The overall goal is to clean water through physical, chemical, and biological processes to make it suitable for local consumption or other reuse applications like watering gardens.

Wastewater treatment
This presentation provides an overview of domestic wastewater treatment. It discusses preliminary treatment including screening and grit removal. Primary treatment involves settling suspended solids. Secondary treatment uses biological processes like activated sludge or trickling filters. Sludge is treated through thickening, stabilization via aerobic or anaerobic digestion, dewatering, and ultimate disposal. Nitrogen and phosphorus can be removed through additional processes.
Characteristics of Waste-Water (Unit-I)
Sewage and wastewater contain organic and inorganic matter, gases, and microorganisms. The organic matter can undergo aerobic or anaerobic decomposition. Aerobic decomposition occurs in the presence of oxygen and forms stable end products. Anaerobic decomposition occurs without oxygen and forms gases and simpler compounds. The characteristics of sewage include physical properties like color and temperature, chemical properties like pH and dissolved oxygen, and biological indicators like BOD and COD that measure decomposability. Proper treatment of sewage is necessary to remove pathogens and pollutants before disposal or reuse of water.

Scaffolding by chakamba j
Scaffolds are temporary elevated platforms used to support workers and materials during construction. There are several types including suspended, supported, rolling, putlog, independent, birdcage, system, and gantry scaffolds. Proper construction involves standards, ledgers, transoms, and guardrails. Regulations require inspection by a competent person and safe work practices like fall protection. Failure to follow regulations can lead to scaffold collapse and injuries.

Formwork by chakamba john
Formwork is a temporary structure used to contain wet concrete until it is cured sufficiently to stand on its own. It supports the concrete and maintains its shape. Common materials used are timber, plywood and steel. Formwork must be strong, rigid, braced and water tight. It supports live and dead loads and maintains shape during construction. Formwork is designed based on the type and location of concrete element being cast. Proper formwork design and construction is important for safety and to produce high quality concrete surfaces.
