There are different sewage treatment technologies and designs like MBBR, MBR, SBR and FBR. Apart from that, there is a chemical and biological process. Majorly Biological treatment process is followed to treat the wastewater, but some companies use chemicals to achieve the desired results in the Biological process. You can choose the technology and the method according to our needs and requirements. You can achieve the results by adding chemicals, but it makes the water not suitable to reuse. Treated water with chemicals may be good for a one-time application like floor wash and gardening. You cannot reuse it multiple times as the chemical in the water deteriorates the quality of the water. Keeping this in mind in OxyO, we do not use any chemicals, which has helped us achieve excellent water quality. You can reuse the water multiple times without any hassle.
Let us look at 5 benefits of not using chemicals in wastewater treatment plants.
1st Benefit – Quality of the water is good
The water achieved from the chemical-free process is of excellent quality. The quality of the water is as fresh as the raw water from natural sources. When you use chemicals, the chemicals remain in the water, which can only filtration can remove. When you have a filtration process, it increases the maintenance cost. So it is advisable to check the process and the technology before going implementation.
2nd Benefit – You can reuse when there are no chemicals
When you plan to use the water for multiple purposes, water with chemicals is not advisable and suitable. Different chemicals are used in the treatment process, and it affects the plants when you water the plants. Gardening is the most common use for any treated water plant, and when the client cannot use the water for gardening, the total project becomes useless. The subsequent use of the treated water is for flushing in the toilets; the colour of the water may change, creating an unpleasant smell and colour. So if you do not use any chemicals in the sewage treatment plant, the water can be reused multiple times by you.
3rd Benefit – Reduction in cost
When we do not use any chemicals, the cost is less as we do not have to buy the chemicals. Apart from buying chemicals, the cost of procurement, storage, and workforce that needs to be handle should also be included. Also, knowledge of procuring the correct quantity and quality should be known, otherwise using low-grade chemicals becomes useless.
4th Benefit – Reduction in using raw water
When you can recover an excellent water quality, you can use the treated water for multiple purposes, which helps you reduce the dependency on freshwater, which is an additional saving. We save by reusing the treated water and again from not buying freshwater.
5th Benefit – Environmental Benefit
The water ends up in some of the water bodies or on the earth. The chemicals present in the water seeps into the soil and ends up in the underground water resource. You may not feel the repercussions now, but soon it will affect not you but our future generations. For example, in Tirupur, the dying units were disposing of water into the ground at an alarming rate. Agricultural lands in and around were getting affected and after protests from people, they have now banned discharging the effluent water into the rivers.
Thus the five benefits of having a chemical-free treated water.
