Industrial water management is more difficult than ever. Industrial wastewater contains a much higher concentration of pollutants than residential sewage, including heavy metals, chemicals, and organic compounds. Moreover, emergent contaminants (specifically pharmaceuticals) make it difficult for current technologies to ensure proper sanitation.
Industrial water management is even more challenging in Asian countries due to poor infrastructure and deteriorating water quality. Fortunately, numerous innovations and technologies are focusing on streamlining industrial water management. Here’s a closer look:
Digital Twin Technology
Digital twin technology has been around for a while, but was mainly used in the healthcare and automotive industries. Industrial water management is now leveraging digital twin technology to optimize operations through real-time monitoring and simulation.
Look at it this way: Digital twins are virtual replicas of physical water systems. However, it contains live sensor data, including flow and pollutant levels. As a result, operators gain a real-time view of plant performance.
Digital twin technologies also allow operators to simulate changes in parameters like aeration, carbon dosing, and sludge management. The aim? Find the most effective wastewater management strategies and test them in a risk-free virtual environment.
A water treatment company can use this technology to detect anomalies, such as excessive sludge, by comparing current data to pre-recorded expected data patterns.
Smart Water Technologies
Smart water technologies refer to the usage of artificial intelligence (AI) and the Internet of Things (IoT). They help collect real-time data on water quality and usage.
Smart water systems also predict maintenance needs and optimize overall plant processes to optimize their performance. Key applications of AI in industrial water management include:
- Real-time monitoring of chemical usage to avoid underuse and overuse.
- Enhanced water quality by detecting chemicals and pollution plumes.
- Predictive maintenance to keep equipment up and running at all times.
- Leak detection and leakage prevention.
With AI algorithms and IoT devices, an industrial wastewater management company can ensure greater efficiency and reliability.
Reverse Osmosis
As hinted earlier, industrial wastewater is concentrated with complex contaminants. This is why advanced filtration methods, such as reverse osmosis, are important.
It is a pressure-driven filtration process that uses semi-permeable membranes to purify water. High pressure forces water to move through the membrane, which removes dissolved salts, minerals, and bacteria from the water. Reverse osmosis is a green way to treat water, as it doesn’t involve the use of chemicals. This method is especially useful in Asian countries where access to chemicals is already limited and poses significant environmental dangers.
Once reverse osmosis is done, the permeated (purified) water is used for industrial processes, and the concentrated (non-purified) water is disposed of.
Zero Liquid Discharge (ZLD)
As the name indicates, Zero Liquid Discharge aims to eliminate all wastewater by treating and reusing all water within the facility, leaving only solid waste behind. The aim? Promote a more circular water economy.
Think of it as a closed-loop system. Wastewater is purified through a series of methods, including reverse osmosis, and is even evaporated or crystallized. The purified water is reused for industrial processes. This also ensures the recovery of valuable minerals and salts from wastewater.
