This document discusses biochemical oxygen demand (BOD) analysis. BOD is a measure of the amount of dissolved oxygen needed by aerobic biological organisms in water to break down organic material present in the water. When organic matter is present in water, bacteria consume dissolved oxygen as they break down the waste, leaving less oxygen available for other aquatic life. The BOD test determines the amount of oxygen consumed by bacteria over a 5-day incubation period at 20°C. A higher BOD indicates more organic pollution and less dissolved oxygen in the water. The standard BOD test involves diluting water samples, measuring initial dissolved oxygen, incubating in bottles for 5 days, and measuring final dissolved oxygen to determine oxygen used by bacteria.

The document then outlines how algal wastewater treatment systems work by using algae and bacteria in symbiosis to remove organic matter, nutrients, and pathogens from wastewater over time in facultative, high rate algal, and maturation ponds.
This document summarizes different methods of disinfecting water, including chlorination, ozonation, treatment with lime, iodine, bromine, ultraviolet rays, potassium permanganate, silver, and boiling. It provides details on the chemical processes involved, advantages, and disadvantages of each method. Chlorination is described as the most commonly used and effective method, involving the addition of chlorine to water to form hypochlorous acid and hypochlorite ions which kill bacteria. The ideal pH for chlorination is below 7 to maximize the amount of hypochlorous acid present.
This document describes an investigatory project on sterilizing water using bleaching powder. It discusses the need for water purification, provides background on bleaching powder and its use in water treatment. The experiment aims to determine the dosage of bleaching powder required to disinfect different water samples.

2. BACKGROUND
Copper is probably one of the oldest bactericides and
algaecides known to man for the control of bacteria,
algae and fungi in drinking water.
Water, a not always unlimited resource, is the essential fluid for all living beings.
Access to water has become a global issue of public interest that goes beyond the
social, economic and geographical inequalities
Already in ancient Egypt the water is left in copper vessels to purify it and its use
has been well documented since 1850. It is located as a natural element on earth
and, despite being highly reactive and toxic to many bacteria and algae, is
beneficial to the plant and animal life.

stable dissolution of copper ions
Occurs with food grade elements and does not generate waste byproducts
and in their manufacture.
In it application complies with the provisions of the WHO recognizes a
maximum level of up to 2 ppm for copper in drinking water treatment.
It is not toxic to humans and animal life and is friendly to the environment.
No biomagnification occurs. Copper does not accumulate or concentrate in
the food chain.
This is a biocide which is presented as a …

4. As the copper, the silver has been in use historically like bactericidally. The ions
silver act as pratoplasmic poison on having combined with the proteins of the
bacterial cells.
* The combination of Cu + Ag + ions increases the bactericidal action of
copper and no generate disinfection byproducts.
In the US, many water production companies use copper-silver ionization as a
clear substitute for chlorine to prevent the formation of these products.

¿WHAT IS ACP (copper and silver)?
It is a unique suspension * copper and silver ions in
aqueous solution itself has properties that help in the
disinfection process.
