pH stands for "potential Hydrogen". In the field of civil engineering, pH is a factor that is considered in corrosion control, coagulation and water softening. All the pH related processes are controlled by civil engineers. pH test is beneficial to check the A controlled value of pH is desired in water supplies, sewage treatment and chemical process plants.

Uses of ozone and its adverse effect?
Ozone (O3) has various uses across different industries and applications, primarily due to its strong oxidizing properties. Some of the common uses of ozone include: Water Treatment: Ozone is used as a disinfectant in water treatment processes. It effectively kills bacteria, viruses, and other microorganisms, making it an alternative to traditional chlorine-based disinfection methods. Ozone is also used to remove color, odor, and organic contaminants from water. Air Purification: Ozone generators are used for air purification in industries, commercial buildings, and residential spaces. Ozone helps eliminate odors, smoke, and airborne pollutants by oxidizing them. However, it is important to use ozone generators with caution and ensure proper ventilation, as high ozone concentrations can be harmful to humans and animals. Food Processing: Ozone is used in the food industry for various purposes, including disinfection, preservation, and removal of pesticides or contaminants from fruits and vegetables. It helps extend the shelf life of perishable food items by inhibiting the growth of bacteria and mold. Medical Applications: Ozone has limited medical applications and is used in certain therapeutic treatments. For example, ozone therapy is sometimes used in alternative medicine to treat certain conditions, such as chronic wounds or joint pain. However, its medical use is controversial and not widely accepted in conventional medicine.
How long does concrete last?
It depends on the design life [50 -75 years?], the environmental & service conditions, and preventative maintenance practices. Concrete is thought of as being permanent strong and very durable. In actuality it is a very complex, thermodynamically unstable and chemically reactive building material that continues to cure and become stronger for years. It is also vulnerable to many external influences! To obtain maximum life cycle [make it last] there are dozens of protective measures that can be taken to make it Green. An understanding that concretes absorb water and expel internal chemistry for years is paramount to obtaining a long life. That drop of water you put on the surface was absorbed into the interior through the Gel-Pore / Capillary System, present in all concretes. This path is formed when water in the mix comes to the surface during the initial set/curing phase [Bleed Water]. After curing, it's hard, we walk and drive on it, but water we put on the surface is absorbed back into it. This moisture carries contaminates: salts, acidic compounds and carbon dioxide to the interior. Lowering the High pH around steel reinforcement to a point that corrosion cells begin to form on the embedded steel in the matrix. Internal chemistry allowed to migrate out to the atmosphere on the surface results in several deleterious conditions. ASR, efflorescence, ettringite are a few! This is also what blisters or "Burns" a coating off in a very short time. A paint designed to protect the concrete, doesn't stand a chance if alkali is coming to the surface to compromise the bond! First step in obtaining a long lasting concrete is to Stabilize It by waterproofing, to fill the microscopic voids in the capillary system. Nothing going in and nothing coming out of it is a Great Start. In reducing Moisture and Oxygen content inside a concrete, you have eliminated two of the four conditions needed for corrosion to commence. A stabilized concrete will give longevity to this very volatile building material, make it Green and prolong it's service life substantially. Answer is: " It Depends On How You Treat It!"
What is pH test in civil engineering?
In the field of water supplies, it is a factor that must be considered in chemical coagulation, disinfection, water softening and corrosion control. In waste water treatment processes pH must be controlled with in range favorable to particular organisms. All these processes are controlled by environmental engineers.
What is pH engineering?
The pH is a measure of the acidity/basicity of a solution.
What does pH test for in water?
pH determination is a test for acidity/basicity.
Use of sensor in industies application?
application of pH sensor?
What are three safe methods to test for an acid?
1. Test with a pH paper. 2. Test with a liquid or solid pH indicator. 3. Measure the pH with a pH-meter.
What is the ideal pH?
An ideal pH doesn't exist; this depends on the application.
How can you test pH in milk. Is litmus paper sufficient?
we can test pH in milk by pH meter.No litmus paper is not sufficiet.
How can you test pH levels?
if available it can be tested by PH meter. if not you can test it by tornosol paper
How do you test the pH of bleach?
You can use a pH paper.
How do you find the pH level of Gatorade?
You can test it with a strip of the stuff you use to test pH levels
Why do you test soil?
you test the soil to check how much PH it has. plants need the right PH
How do you measure the pH levels in a tank?
You can measure the pH in an aquarium by a pH test kit, or by using an electronic pH monitoring device. There are also other ways to test.
