How do you calculate chlorine feed rate?

How do you calculate chlorine feed rate?

Divide the daily chlorine input by the MGD flow of the facility. In the example, the result would yield 33.33. Divide the result by 8.34 pounds per gallon to find the chlorine concentration. In the example, the concentration is 4 milligrams per liter.

What does Mclg mean?

After reviewing health effects data, EPA sets a maximum contaminant level goal (MCLG). The MCLG is the maximum level of a contaminant in drinking water at which no known or anticipated adverse effect on the health of persons would occur, allowing an adequate margin of safety.

What is the ppm of chlorine in chlorinated water?

What are safe levels of chlorine in drinking water? Chlorine levels up to 4 milligrams per liter (mg/L or 4 parts per million (ppm)) are considered safe in drinking water . At this level, harmful health effects are unlikely to occur.

What is turbidity EPA?

Turbidity is a measure of water clarity how much the material suspended in water decreases the passage of light through the water. Suspended materials include soil particles (clay, silt, and sand), algae, plankton, microbes, and other substances.

How much chlorine do I need for 1000 Litres?

To dose water in a tank with 5 mg/L chlorine use: 40 millilitres of liquid pool chlorine or 170 millilitres of bleach, for every 1000 litres in the tank.

What is MCLG and MCL?

A MCLG or PHG is a level of a contaminant in drinking water below which there is no known or expected risk to human health. MCLGs are non-enforceable public health goals. An MCL is the highest level of a contaminant that is allowed in drinking water.

What do MCL and MCLG stand for?

MCLG: Maximum Contaminant Level Goal Then, the EPA establishes a Maximum Contaminant Level Goal (MCLG) for the contaminant in question.

How much chlorine is in bleach?

6% chlorine
A Clean Pool: Chlorine vs. Bleach. Typical pool chlorine is actually a chemical compound made up of 65% calcium hypochlorite with the remaining 35% made up of calcium and other inert ingredients. Household bleach, on the other hand, is usually only 6% chlorine and a different type at that.

What is a good turbidity level?

The WHO (World Health Organization), establishes that the turbidity of drinking water shouldn’t be more than 5 NTU, and should ideally be below 1 NTU.

What is the difference between NTU and PPM?

1 NTU is equal to how many ppm? You cannot simply say x NTU = y ppm solids. NTU is a measure of light absorption. PPM is a measure of concentration. The ratio between the two depends on how much light the particles you are measuring adsorb per mg of particle.

What is NTU in water purification?

NTU stands for Nephelometric Turbidity unit, i.e. the unit used to measure the turbidity of a fluid or the presence of suspended particles in water. The higher the concentration of suspended solids in the water is, the dirtier it looks and the higher the turbidity is. NTU units are most commonly used by purification plants.

How do you calculate the initial concentration of a bleach solution?

The calculation performed in this tool is based on the following equation: C1 x V1 = C2 x V2 C1 is the initial concentration of the bleach (sodium hypochlorite) solution.

How many NTU is 300 mg/l of water?

For example, 300 mg/l (ppm) of SS are 900 NTU. According to the World Health Organization, the turbidity of drinking water should never exceed 5 NTU
