SCADA Systems - Wastewater Treatment Products
What is SCADA? Know more about this System and Its Advantages
Like oxygen even water is extremely crucial for the survival of all living organisms on our planet. But unfortunately in recent times access to clean and safe water resources are becoming increasingly difficult as various human activities has lead to significant water pollution and contamination problems. conservation and purification of various water resources has become of pivotal importance. This is driving various countries around the globe to look for new alternatives to fresh water like seawater desalination, reverse osmosis etc. But the good news is that with proper wastewater treatment systems one can conserve water resources from water pollution in the most cost effective way.
Efficient wastewater treatment plants ensures1 that the receiving water resource into which the effluent is finally discharged is not contaminated or polluted significantly. Not just that wastewater treatment technology also targets at making clean water readily available to the public at large. Moreover in order to increase the efficiency of wastewater treatment plants SCADA systems are integrated into the same. This has helped making the wastewater treatment process increasingly cost effective. SCADA application is used not just for wastewater treatment but also for water treatment and water distribution.

What is SCADA?
Supervisory Control and Data Acquisition usually referred to as SCADA can be used to describe a multitude of computer based control systems. It is one of the main water software used for wastewater process automation. SCADA systems enable the operator and facility personnel to locally or remotely control and monitor a wastewater treatment plant or facility's equipment. Ideally most of the control process is automated by SCADA systems so that the plant operator can focus on other tasks. Although automated these systems design also offers the operator flexibility to manually control the equipment whenever desired. Further, functions like collection and storing of information for reporting, maintenance indications, troubleshooting, and more are also one of the main features of SCADA.
SCADA infrastructure processes are either private or public. However, the system includes water treatment and distribution, wastewater collection and treatment. SCADA programs are a process control application that is used in various industrial applications. This offers centralized monitoring and recording reading of pumps, tank levels, temperature, switches etc. These systems are also referred to as Human Machine Interfaces (HMI), or the less politically correct Man Machine Interfaces (MMI).
Functions of SCADA Systems in Wastewater Treatment Plant
Supervisory Control and Data Acquisition (SCADA) Systems are often integrated in water and wastewater treatment systems for the following functions:
SCADA systems are capable of running standard control algorithms like P, PI, and PID regulatory control algorithms. This is used for maintaining specified levels in tanks, maintaining the required flow rates, and maintaining processes at the right temperatures and pressures. SCADA systems can also execute some form of Boolean logic for automation of starting and stopping of pumps, opening and closing of valves, and other discrete functions. These systems also usually offer some command set or scripting language to serve as a programming tool to allow for the need to sequence or stage these functions.
SCADA systems are primarily utilized in wastewater treatment plants to control and monitor lift station pumps, valves, tank levels, eliminate well pumps, high service pumps, and chemical pumps. Also one of the main functions of this system is to offer an effective visual interface between the process and an operator. Most SCADA systems generally have an advanced set of tools that displays individual process values. They also offer the means of taking real time data and showing it as a tread so that subtle process changes can be observed.
SCADA systems are programmed to process data and archive selected information into electronic records that can be recalled or reviewed at any time. In most cases, data on SCADA systems can be exported to different applications like MS-Excel or MS-Word for further analysis or formatted into reports. Also at the time of printing these reports, the dates and times of this event are recorded. This serves as a chronological record of changes that occurred within the system, i.e., what alarms occurred, what set point changes were made, and what equipment was started or stopped.
In wastewater treatment plant, SCADA systems are used to monitor a series of plant data and information. This includes reading of flows, motor currents, and voltage, level of water, temperatures and pressures. If any abnormal conditions occur and are propagated to the HMI computer then alarms situated at central or remote sites are triggered for immediate operator's attention.
SCADA systems have statistical packages incorporated that can be used to analysis of process data online to identify and detect any changes that as occurred in the process.
It also offers diagnosis if there is a failure in control components and in any process function in wastewater treatment plants.
Advantages of SCADA Systems For Wastewater Treatment Plant
There are a numerous advantages of having SCADA systems integrated in wastewater treatment system. The same are as follows:
- SCADA system helps in reducing the operation costs. It also helps in improving system performance and reliability.
- SCADA systems help with indicating the nature and degree of a problem if it occurs in a wastewater treatment plant. This helps in avoiding costly after-hours alarm call-outs to a large extend.
- This system records process data continuously. operators no longer have to manually read, record or maintain meter reading on a daily basis.
- Every data recorded on the SCADA system can be accessed, reviewed and downloaded at any point. the operators no longer have to keep track of hundreds of log sheets.
- Lastly, information and data on SCADA systems can be accesses remotely through an Internet connect on your office computer, laptop, cell phone and even tablet.
In the market, SCADA systems for wastewater treatment plants range from basic to highly complex systems. Also a very well designed SCADA system can make the most complex configuration both easy to maintain and user friendly.
Based on the above we can conclude that wastewater treatment plants integrated with SCADA systems can be very cost efficient and highly productive. if you are looking for the right wastewater treatment process and plants with SCADA system then we at IDS Water have it all and much more. So what are you waiting for just browse through our directory as it will provide you with the details of numerous prospective vendors, vendors and suppliers to meet all your wastewater treatment needs.
