Water And Waste Treatment

Water And Waste Treatment

In this article, I discuss why COD is a critical factor for the treatment of wastewater.

Wastewater COD (Chemical Oxygen Demand) is the amount of oxygen necessary to oxidize the organic carbon completely to CO2 and H2O. Some organic chemicals are not completely oxidized. However, COD is measured in approximately 3 hours via oxidisation with potassium bichromate (K2Cr2O7) in the presence of Sulfuric Acid and Silver Sulphate. During the Wastewater COD test, other reduced substances (e.g., Sulfides, Sulfites, Fe++) ar also oxidized and included in the waste water COD. Furthermore, decreased forms of organic Nitrogen are Read the rest of this entry »

Wastewater Treatment Systems

Wastewater Treatment Systems

Most of us flush the toilet without a second thought, but what happens to the wastewater if the property’s non connected to mains drainage?

There ar several options available to homeowners:

Cesspits and cesspools

A cesspit or cesspool is simply a holding tank for receiving and storing wastewater from a property. The wastewater enters the cesspit where it remains until it is emptied by a vacuum tanker. As the cesspit merely holds the wastewater rather than treating it, the tanks tend to fill quite quickly resulting in the Read the rest of this entry »

Not long ago, I was discussing the topic of vehicle fleet washing with an environmental specialist working with a municipal water treatment facility. You see, the affluent that comes from vehicle washing is not that benign. For instance it’s often filled with grease, oil, petroleum distillates, asbestos from brakes, heavy metals, acids, and whatever soaps and detergents are used – not exactly what you want in the local environment. Now then, how does a company that cleans lots of vehicles, either on contract, or their own fleet suppose to deal with this?

Well, they need a Read the rest of this entry »

Waste Water Treatment Technology

Waste Water Treatment Technology

Today’s society has a voracious appetency for fuel, whether it is for use in transport or heating homes. Oil production, unfortunately, produces large amounts of waste water during the process of extracting oil. All Oil and Gas reservoirs have layers of natural water and hydrocarbons (a naturally occurring organic compound comprising hydrogen and carbon). In oil and gas production extra water needs to be injected into the reservoir to maximize the separation of its components. The waste water produced (“produced water”) in this process contains many harmful substances such as hydrocarbons which need to be remote before the water Read the rest of this entry »

Waste Water Treatment System

Waste Water Treatment System

Every home produces wastewater. The water is produced through washing, bathing and flushing of the toilet. Before being released back into the environment, the water that is produced moldiness undergo wastewater treatment.

If you home does non have a connection to a populace sewage disposal system, you moldiness have an onsite treatment system. Typically this is handled through use of septic tanks. The tank breaks down organic waste and allows treated wastewater to flow back into the aquifers.

Septic tanks depend on helpful bacterial to dissolve many of the solid wastes that enter Read the rest of this entry »

Waste Water Treatment Process

Waste Water Treatment Process

Waste water treatment is the process of removing household and institutional wastes from the water supply. In most of the developed world, the process has been refined and is quite effective astatine conserving this life-sustaining element known as H2O.

Household wastes, also called sewage, consists of debris that comes from toilets, sinks, kitchen garbage disposals, baths, and showers. Industrial wastes can be some of the same, though will usually also admit contaminants like manufacture by-products that are flushed through the factory’s or other commercial facility’s sewerage system.

The treatment process involves astatine least Read the rest of this entry »

Drum-Kickers, Soap Salesmen…they have been called many things. Water Treatment specialists (probably the name they prefer) ar everywhere. As a mechanical contractor, we have had many knock on our door. With most large commercial buildings and industrial facilities in Memphis utilizing water cooling/heating mechanical equipment, this industry is highly competitive, but is water treatment really necessary? In this edition of Mechanical Matters® I am going to answer that very question and discuss several other important facts about water treatment services.

In this edition I want to answer three questions regarding water Read the rest of this entry »

There ar many reasons to consider having some form of in-home water treatment installed, and there are also many installation options. Point of use systems, point of entry systems, and free standing units can be elect depending on your consumer issues and needs. Your consumer needs may lean more toward health and safety, mere convenience, or elimination of embarrassment due to cleanliness issues, but there is a solution for you and your home.

A point of use water treatment system will essentially treat the flow at a single point in your home. These systems ar popular Read the rest of this entry »

Waste Water Treatment Methods

Waste Water Treatment Methods

Water is, aside oxygen, a vital element for life on earth. Access to clean drinking water is mandatory for life to go on as it is today. As the world’s population is increasing more and more and the water sources remain astatine the same level, timely wastewater treatment is of the essence so that the natural water reserves refill astatine a constant pace.

Wastewater and, generally speaking, water-treatment means destroying or removing those elements from the water that could be harmful to humans. The treatment processes today remove up to 99% of water contaminants from either Read the rest of this entry »

Waste Water Treatment

Waste Water Treatment

Fine bubble diffusers are used to aerate wastewater for sewage treatment and reduce pollution. The goal is to reduce the amount of remaining sludge, which depends on the amount of solids generated and other conditions. Fine bubble diffusers are used in aerobic digestion, primarily in bigger scale wastewater treatment.

The aerophilic digestion employs living organisms to naturally reduce the amount of organic waste and the amount of disease-causing microorganisms. Aerobic digestion can also be achieved by using diffuser systems or jet aerators to oxidize the sludge. Aerobic digestion is a bacterial process occurring in the presence Read the rest of this entry »
