Modern Waste Water Treatment Technologies For Better Future

It is said that the Third World War will be enforced because of water. It is true; water is very precious on this verge of explosion of population and growing water needs. Waste water treatment and recycling of water has great importance in this view. Many waste water technologies have been developed to make water clean, potable so that it can be reused for different purposes including agriculture and other needs. While designing waste water treatment plant, it is essential to implement different waste water treatment technologies according to the need of water treatment requirements. Whether you are developing waste water treatment plant for residential unit or industrial, there are many technologies established to suit the specific requirements. This article reveals different water treatment technologies. The modern technologies in waste water treatment offer excellent results and ensure safe water for reuse.



Know About different Waste Water Treatment technologies Available

The emergence of waste water treatment technologies facilitate to remove harmful pollutants, to make it clean and safe for reuse or discharging it in the environment. The technologies today can be broadly classified as –

  • Mechanical waste water treatment technologies which combine biological, physical and chemical processes to treat the waste water.
  • Aquatic technologies which are usually used for water storage. The most commonly used technology is lagoon technology.
  • Terrestrial technologies facilitate to recycle water for agriculture, ground water recharge, reforestation etc.
The mechanical waste water treatment technologies utilize components like tanks, pumps, blowers etc. Let’s see some of the commonly used and effective waste water treatment technologies –

  • Microfiltration – It is also referred as synthetic membranes. These filters are capable to remove microorganisms from the contaminated water. The waste water is passed through the filters more than once to achieve the desired level of water purity. The technology is combined with other chemical treatments to assure safe and potable water.
  • Aerated lagoon technology – This technology is used where treatment is given to the waste water storage. The artificial aeration of waste water helps biological oxidation. This technology accompanies different processes or methods like biofilters, trickling filters or use of biological contractors.
  • Aerobic water treatment technology – It employs useful bacteria to kill harmful microorganisms from the waste water.
  • Chemical water treatment technologies – The variety of chemical waste water treatment technologies like ion exchange, ozonation, coagulation, chlorination etc. are emerged to remove dissolved water contamination and make it safe for disposal or reuse. Many chemical solutions are available to treat waste water and remove the unwanted and harmful impurities easily.
Besides these techniques, many other technologies such as sedimentation, degasification etc., are implemented in primary and secondary treatment phases to assure water purification. The treatment plant is designed accounting all factors like type of wastes, volume of waste water and the best suitable water treatment technologies. The combination of different technologies gives excellent results for different applications. Thus, it is important to select the most effective, energy conservative and suitable waste water treatment technologies at different sites.

Efficient And Effective Technologies For Industrial Waste Water Management

Waste water management is the key issue for many industries generating large volume of waste water in various processes. Effluent treatment plant is very important to manage waste water treatment and achieve the norms given by government bodies. To avail the quality water, various advanced technology solutions are developed today. You will find an array of technologies in industries waste water treatment solutions to get economical yet effective results. Do you want to know more about the technologies used today in industrial water treatment? This article focuses on the different water treatment technologies which are widely used and how they are efficient for different industry requirements.



Industrial Water Treatment Techniques

While devising the waste water treatment plant for any industry, it is essential to assess the type of waste water released from the industrial processes. This waste water can be contaminated with heavy oil quantities, or hazardous chemicals, corrosive materials, metals or other harmful substances which make water unfit for its reuse. One has to consider all these factors while choosing right treatment processes, equipment or technologies. Pumping of the waste water is inevitable activity in any effluent treatment plant. Hence, pumps used in the plants must withstand with the waste water as well as handle it efficiently. That is why; chemical process pumps have been developed in the market. These pumps are not only used in wastewater treatment plants but also used in transporting various chemicals within the industry. A wide range of chemical process pump helps to handle hazardous and corrosive chemicals or waste water.

Let’s see some widely used technologies in effluent / water treatment plants in the industries.

  • Mechanical filtration – This technique is capable of filtering even tiny particles of mud/sludge from the waste water. Most commonly used filtration methods include cartridge filters, indexing paper filters and media filters. 
  • Electro-coagulation – The low voltage current is passed through waste water which allows contaminants to coagulate and separate from the water. This process can remove suspended solids, heavy metals or emulsified oils from the waste water.
     
  • Ozone treatment (ozonation) – The ozone gas (O3) is injected in to the flow of waste water. This process kills microorganisms in the waste water as well as helps deodorize it.
     
  • Chemical treatment – The precise amount of chemicals are injected in the flow of waste water to remove contaminants. The process is commonly known as coagulation and flocculation.

Besides these techniques, many other techniques like bioreactor membrane, reverse osmosis, ion exchange etc. are used to treat industrial waste water. These modern techniques are effective and efficient to provide clean and safe water. The best suitable techniques should be implemented in the industrial water treatment plants to avail the desired results. The powerful pumping systems have also developed in the market to suit specific needs of different industries. Many effluent treatment plant companies help industries to design, install and commission the water treatment plants successfully. Even maintenance services are provided to keep the treatment plant running efficiently.
