What is EDI in a Water Treatment Plant? – Electro deionization

 In this post, we will see the concept of Electro deionization (EDI) in a water treatment plant. Water treatment plants are used to convert bad wastewater into drinkable or usable water. The quality of the water coming out of these plants need to be maintained for proper human use. Such plants are used in almost every industry; as quality water demand is a must for the personnel to use or machines to operate. The water content is monitored by various types of sensors, which help in maintaining the final output. Without them, it is impossible to operate the plant. Many components are used in a water treatment plant to treat bad water. One such component is EDI (Electro deionization). In this post, we will see the concept of EDI used in water treatment plants. It is one of the most essential components used in these types of plants. Why EDI is required? Conductivity means the ability of water to conduct current. It is one of the important criteria in determining water quality. Low co...

How does SMPS Works? – Switched Mode Power Supply

 In this post, we will see the working of SMPS. SMPS stands for Switched Mode Power Supply. It is an essential part of an electrical power circuit. Basically, power is required in different forms for various circuits. So, we just cannot feed raw AC power to them. Such type of conversion is done by SMPS. Its role is to provide the necessary supply voltage to electrical circuits in their required form. As the name implies, the power supply is altered and obtained in various forms by means of switching devices inside it. They switch the power in various ways to provide the final output voltage. These switching devices are nothing but power electronic devices like triac, diac, transistor, MOSFET, capacitors, resistors, etc. SMPS is majorly categorized into four types – AC to DC converter, DC to DC converter, Forward converter, and Flyback converter. In this post, we will have a look at the working of one of the most widely used types – AC to DC converter. AC to DC converter is used to ...

What is Seal-in Circuit ?

 A Seal-in circuit is a method of maintaining current flow after a momentary switch has been pressed and released. What is Seal-in Circuit ? Fig 1 : Start button not pressed Note : Consider a Relay is used to control the power supply to a motor. Here we are calling this relay as ” Motor Starter Coil “. This Relay another NO contact is used to seal-in or latch the start signal. As start push button is a push & Release type i.e. signal will be available for some time say momentarily and then signal will be lost. so we have to latch this circuit in order to make motor run continuously even after release of start push button. For this purpose we are using Relay (M) NO contact across Start push button such that it will take care of start signal after start button is released. The seal-in auxiliary contact (NO Contact) of the starter (M) is connected in parallel with the start button to keep the starter coil (M) energized when the start button released. After Start Push button presse...

Rockwell Automation Allen Bradley PLC for Smaller and Medium Projects

 Allen Bradley PLC Course: Register for Free Rockwell is a very big brand in industrial automation. It has very products and innovative technologies in industrial automation, residential and small business, low voltage products and systems, solar and energy storage, medium voltage distribution and grid automation, etc. If we consider the industrial automation part, it has a very wide range of PLCs. Rockwell Automation Allen Bradley PLC In this post, we will have a look at various ranges of Rockwell PLCs. For your information, Allen Bradley is nothing but the automation brand owned by Rockwell Automation. So, Rockwell PLCs are also termed as Allen Bradley PLCs. This range of PLCs is divided into three parts – Micro, Small and Large Let us have a look at all of them. Micro Range PLCs Micro 870 PLC This PLC supports up to eight expansion modules with an IO capability of 304 points; including high-speed inputs, PTO, and interrupts. From a communication point of view, it has an embedded...

Condensate Automation in the Sugar Industry

 In this article, we will study what condensate automation is? And what is the purpose of it? The condensate automation systems are mainly employed in the sugar industry, distillery, paper industry, chemical industry, and so on. The purpose of the condensate automation system is to cool down or reduce the temperature of the exhaust steam and the vapor outlet. But in this article, we will discuss the condenser in the vacuum pan in the sugar industry. Principle of Condenser Automation in Vacuum Pan As the massecuite level in the pan rises, the rate of evaporation is reduced and therefore water required to create the vacuum is less. When the vapor is mixed with injected water in the pan and the vacuum is created at the outlet tailpipe. The temperature difference between vapor and vapor-condensate also affects vacuum generation. The injection of water reduces the temperature as per Ambient. Purpose of Condenser Automation To control the water with respect to vacuum vapor and NCG load. ...
