Studies show that the conversion of wastewater into reusable forms can decrease water shortage by as much as 30 per cent in a year. Also, modern wastewater solutions promote environmental sanitation to prevent infection and contamination.

How Does Wastewater Treatment Initially Occur?

Wastewater treatment involves several procedures that must be performed stepwise to ensure proper disposal. Initially, wastewater is collected from houses and offices for drainage into a principal point. Wastewater flows through pipes and moves into an underground drainage system. Treatment facilities then use chemicals to counteract the unpleasant smell of sewage. Screening for solids, such as plastics, bottles and garbage, is also done to eliminate objects that will impede the water treatment process.

What Are the Steps in Wastewater Treatment?

After collection, gross inspection and initial screening, the treatment process will ensue. Primary treatment involves placing wastewater into large containers for sedimentation. Through this procedure, the denser sludge settles on the bottom of the tank and is then eliminated. The filtered water then undergoes further decontamination during secondary treatment.

Secondary treatment involves chemical oxidation, which is characterised by water disinfection techniques to kill microorganisms. Addition of chlorine and hypochlorite are standard techniques to prevent the growth, respiration and metabolism of bacteria.

The non-renewable sources that have been initially filtered and collected during initial treatment require further processing before being released into the environment. Sludge is thickened and placed in aeration tanks to ensure that it is adequately treated before disposal.

The Bottom Line

Wastewater can undergo a series of processes during its conversion to renewable forms. The remaining two per cent comes from human excreta, solids and debris that can no longer be reused into potable water. Hence, it is essential to have regular wastewater treatment in commercial and residential areas for environmental sustainability.

Chemical-Free Cooling Tower Water Treatment

Comments Off on Chemical-Free Cooling Tower Water Treatment

water treatment systemWater cooling towers are important in cooling the water that circulates nuclear power plants, oil refineries, renewable energy facilities, dairy and food processing industries, and other heat-intensive industrial systems. But, the process of cooling and treating water is costly and damaging to the environment.

With advanced technology, companies like Superior Water Conditioners can conduct chemical-free water cooling and treatment using systems that resist corrosion and bio-contamination.

Use of Electrolysis Technology

Through the use of a turnkey solution that uses electrolysis to condition water, the system splits water into an acid and a base. The acidic solution activates chlorides into biocides while the basic solution precipitates scale-forming minerals. This electro-chlorination and electro-oxidation processes destroy organic matter that causes macro and micro fouling, producing the best water conditioning. The water is neutralized by naturally occurring calcium and magnesium ions that act as a buffer for corrosion.

Principles of Physics

Traditional and chemical water treatments change the characteristics of water to stop corrosion and control biological growth. In contrast, physical techniques are used to treat the equipment in newer water treatment towers. The physical systems have come a long way in preventing scale, corrosion and other harmful products that may be present in hard water in the heat exchange transfer equipment.

Latest Automated Technology Service

Communication is a vital process in cooling tower water treatment. Some technical issues may need to be addressed at various times, including breakage and maintenance. The machines need to be automated so that they can detect minor problems. The use of iPad, computerized systems, basic equipment, handheld conductivity meters, and cell services will be helpful.

It is essential to have the latest technology that will ensure that you can cut costs, save the environment and also save water by using the chemical-free cooling tower water treatment.
