The universal fact is that water is a precious, indispensable resource and basic necessity of life. Urbanization & Globalization, the usage of water is increasing day by day. The power-packed industries like oil, pharmaceuticals, and chemicals have generated a massive volume of wastewater containing toxic & non-toxic chemicals affecting the environment. Sewage Treatment Plants
The exclusive Smart Water Management is involved in the incorporation of systems that are used to monitor, control, and regulate the usage of water. The industrial and government sector has come with many ideas to eradicate wastewater by making use of Zero Liquid Discharge System (ZLD) to achieve an evergreen eco-friendly environment. Are you curious to know about Zero Liquid Discharge & Sewage Treatment Plant? Just scroll down the page.
Quick Insight about Zero Liquid Discharge
Zero Liquid Discharge is a precise filtration process where it targets to procure a reputation as freshwater resources all over the world continues to diminish. On the other side of the flip, the environmental protocols for wastewater discharge grow in a vivid state. This gigantic technology holds an integration of both the pretreatment & evaporation to congeal the solids and we can reuse this water. There are multiple water treatment processes to increase the restoration of freshwater and reduce wastage, but as of now, ZLD is the most demanding one.
A closer view
The factors like salinity, scaling compounds & organics enhance in terms of concentration. In this gigantic system, the wastewater is systematically pumped from the sewage pond into the feed tank. Here, the pH level is adjusted for decarbonization. With the medium of the heat exchanger, the sewage water is processed where the temperature is increased to the boiling point. Then the pumping process takes place towards a deaerator, gases like carbon dioxide & oxygen are removed completely from brine.
Water Treatment System
Generally, sewage water treatment is a typical process where it removes the contaminants from wastewater including effluents. There are several processes like physical, chemical & biological to eradicate the contamination from water. The online monitoring system for STP is feasible for the execution of primary, secondary, and tertiary systems. Ultimately, the main target is to produce a safer environment & a solid waste adaptable for the reused concern. In more precise words, the treatment facilities are mainly designed to upgrade the natural process of removing contaminants from water. In case if there is no evolution of sewage treatment, the wastewater can cause devastation globally. While comparing in the world level, about eighty percent of the wastewater is released without an initial water treatment too.
In this present era, most countries have implemented water treatment facilities. They make use of multiple methods to purify the water, send it back to the environment and keep everyone safer. To minimize the scarcity issues, using the treated wastewater is one of the feasible solutions. Due to the developing population, we are in greater need of the water conversation. By our smart minds and making use of the latest technologies we can involve in a new change in the process of wastewater treatment.
How industries are making use of Treatment Plants?
Most of the industries have started their water treatment system to save water each & every day. The IoT for Sewage Treatment Plant makes use of the smart sensors and standard smart meters which are installed at different points in the massive water system. Here, the main role of sensors is to collect the data like temperature points, pressure change, water leak detection, etc, and send it to the monitoring systems. Ultimately, Effluent Treatment Plants play a vital role in treating the industrial wastewater and waste of households. This kind of treatment helps in the small-scaled, medium-scale industries to dispose of the effluents completely. If this methodology is not followed, it may be crucial to treat the sewage water. Additional space may be required for the contaminated water treatment.
The sewage treatment process possesses a top-notch potential to reduce waste production and at the same time also produces natural fertilizer from the waste substances. It mainly targets to promote the environment’s health. On the other side of the flip, at a moderate cost, the rehabilitation projects are done successfully. The biodegradable material found in the drying lagoons can be converted into a natural fertilizer. It can be used in different fields such as agriculture, crop yields etc. This one automatically lowers the usage of chemical manures that pollute the entire ecosystem.
Updated technology overcoming SCADA/PLC
In the Programmable Logic Controller, the sensors play a vital role which is inter-connected through the wired system. Its main focus is on the comprehensive subject of information security. Through IIoT multiple devices are integrated, thus the wireless connection is possible. Despite the distance, the objects can be controlled across vast networking. The cost is moderate when compared with that of PLC.
It is clearly understood that transmission of data takes place through SCADA software and final output will be received. While concentrating on IoT for industries, in any means of server architecture, data can be sent & received without any complications. At the same time, the mobile app can also be incorporated when compared with that of the Programmable Logic controller. From the above-discussed points, it is clear that our future path depends on the IIoT and of course, the PLC/SCADA alternative is IoT.
An initiative of the government towards ZLD
Apart from the industries, the government sector has started to initiate the conservation of water in schools, colleges & hotels, etc. Typically, the government of Delhi has asked educational institutions to implement the zero discharge system. In the traditional days, they first started the execution of rainwater harvesting to reduce the wastage of water, especially in schools. They are focusing to save water by recycling through a gigantic zero discharge system. By processing the sewage treatment plant, the result of freshwater can be used in the compounds. To initiate awareness among the students, recycled water through the ZLD system is being used in schools. In a parallel way, they also have a plan to reach zero wastage of water. In the beginning few years, the systematic Zero Liquid Discharge System is expected to be implemented all over India.
