Commonly Faced Problems With Raw Water Treatment And Tips To Avoid Them
Several issues surface while the treatment process of raw water in industrial companies. We have narrowed down some of the most commonly faced problems with raw water treatment and tips to avoid them. Avoiding these common raw treatment problems might help you operate the process more efficiently, whether it be designing a new plant or updating existing equipment.
1. Variation in turbidity With time the water treatment plants begin to experience a variation in turbidity i.e haziness and cloudiness of water because of a large number of particles present in it. This can cause negative effects on the effluent from the plant and the quality of the process. You must have consistent data for at least a year to
evaluate the turbidity levels coming into the plant with the season to the season before designing the system. The chances of several problems to occur increases if the turbidity rises without letting the plant be prepared for the change. It is usually the case when the plant is designed around the seasonal turbidity flow with taking no consideration of changes it might see.
2. Flow Variations Generally, industries make conclusions based on prior incidents or knowledge regarding the flow rates. An industrial facility is more likely to experience upsets to the system unless well equipped to handle these variations in flow. These upsets to the system will carry turbidity over and plug the downstream filters. In such situations, preparing for flow variations becomes necessary by understanding what the peak demand is and using holding tanks to try to buffer out the peak demands. Basically, you want to design the system in such a way that you can run your plant as consistently as possible. Designing the system with an excess flow holding/buffering capacity is a great way to make it possible. And there’s another way you can make it happen is by putting variable controls on your chemical feed systems so that when your flow changes, your chemical feeders can ramp up and ramp down to handle it. by combining variations of flows on feed treatment equipment and storage on peak demands it is possible for you to get your system to balance out more easily and increase functionality. In case you don't have the ability to automate chemicals, you will have to test regularly. Raw water purification plants are not able to handle variations in the flow that well so it is essential to start designing the system with this in mind.
3. Changes in Feed chemistry Water sourced from wells and surface water has seasonal variations in water chemistry. The raw water treatment systems have to build large enough to handle these changes in industrial plants. Industrial water treatment plants have to be designed large enough to handle the increased load. For instance, iron and silica in your raw water changes seasonally and your clarifiers are not large enough to get the proper retention time then you are more likely to carry over with silica and/or iron into the downstream equipment. This causes the problem of scaling and fouling in the systems. It is vital to understand the variations of the contaminants feed water chemistry for the proper system.
4. Secondary waste Another essential part to consider in water treatment plants is considering secondary waste generated by the process. Feedwater contaminants impact the volume and processing requirements in secondary waste. These secondary wastes need to be discharged and treated. However, sometimes, these wastes
are discharged to a publicly owned treatment works or wastewater facility which is why they must meet the requirements of that facility. In such cases, it is recommended to buy from those water treatment plant manufacturers that have a permit to meet the effluent discharge of the plant water.
5. Awareness of changes or updates It is a common occurrence that after the plants have been installed for years after meeting the stringent requirements, end up finding out later that it is needed to adapt recent changes in regulations as well. The plant may be running fine and well designed to deliver a certain kind of effluent quality, then one day the standards of the quality requirements become more stringent making the plant no longer abiding the requirements at the facility.
This is the reason why water treatment plants for industries must be designed with forward-thinking in mind taking what can be possibly anticipated. It is also helpful to allow space in the plant for additional equipment to handle changes in quality requirements.
