Wastewater Management - Methods to Save the Environment

One of the biggest hazards in today’s world is wastewater. Water, when used for various industrial and domestic purposes, accumulates a large amount of waste and dirt that need to be expelled. Not doing so can lead to water becoming an environmental hazard as it interacts with other living organisms in the food chain.

Thus, having a good wastewater management system is a necessity today. There are multiple ways in which wastewater can be treated:

  1. Primary treatment of wastewater
One of the key steps in wastewater management is its primary treatment. It requires the wastewater to be placed in a large tank until the heavier solid particles settle at the bottom. Desludging equipment can be used to discharge these waste particles and then the water can be transferred for further treatment. Desludging  includes the following:

A. Use of RDRO Technology: This is technology that allows for the recovery of valuable water from effluents. RDRO combines the powerful facets of reverse osmosis with an ultrafine gravity filter. It also reduces backwash water volume, space and power consumption and allows for at least 85-90% of the treated water to be recycled.

B. Treatment of textile effluents: Companies such as ATE offer their own versions of the AAA technology to treat textile effluents. The technology uses the dissolved air floatation method to get rid of chemicals and other impurities while at the same time producing methane gas which can be used as fuel.

 C. Treatment of dairy and food industry effluents: In the dairy and food industry, the waste material that mixes with water includes substances rich in edible oils, proteins and fats. The wastewater treatment process used here eliminates all impurities and also releases biogas. This makes the entire treatment process energy neutral. Another positive feature of this treatment is the use of jet mixers for removing impurities.

D. Treatment of pharmaceutical wastewater: This is another form of wastewater treatment which utilizes anaerobic processes to enhance water quality. The RO and UF systems ensure greater membrane life and elimination of sludge that could hamper natural water bodies by choking plants and animals.

There are many other forms of wastewater management as well that are available. They use high technology methods to ensure that the water is treated to its maximum. With environmental concerns plaguing a wide range of industries, having a proper wastewater treatment system serves them in good stead, over the long term. Many companies, today, offer specialised, industry-level equipment for treating different forms of wastewater and making them safe for release and use once again.
