Design and Construction of an Electrocoagulation Package for Wastewater Treatment

Types of rubber (gasket) for sealing in water supply lines\r\nUsually, washers are divided into two categories: rubber and metal.\r\nThere are a wide range of washers such as flat washers, spring washers, spherical washers, lock washers, and square washers. In steel screws, steel or metal washers are used to increase the friction surface and close the screws tightly and not to lose the preload pressure.\r\nWasher application\r\nThe washer is sometimes used as a separator and sometimes as a spreader of load and pressure from a surface such as a rim and flange, sometimes to reduce the vibration of a surface or to seal and insulate and prevent material leakage. Usually, the outer diameter of the washer is twice the diameter. It is inside, sometimes fibrous and rubber sealants are also called gaskets, if the only job of these sealants is to prevent material and liquids from leaking, and gaskets are also used to prevent corrosion of surfaces.

Ozone must be produced on-site; however, the quality of an ozone generation system is not limited to just ozone production. What is shown in the image is part of the Ozone Generation & Control System implemented by Palood Sanat engineers; a system designed for stable operation, equipment control, and integrated management of the ozonation process. Ozone, as a strong oxidizer and disinfectant, can be used according to project conditions in water and wastewater treatment, microbial load reduction, oxidation of certain compounds, and improvement of the final flow quality. However, selecting an ozone generator is not done solely by specifying the device capacity. In an engineering design, flow rate, water or wastewater quality, required ozone amount, gas transfer method to the liquid phase, contact time, control equipment, and safe management of the output gas must all be considered together. At Palood Sanat, the ozonation system is designed and equipped according to the actual conditions of each project; from selecting the generator capacity and auxiliary equipment to the control panel, instrumentation, and integration with the process line. Design and implementation of ozonation, disinfection, and water and wastewater treatment systems

The Hamoon design nozzle is a widely used spray nozzle in cooling towers, used for uniform water distribution over the packings. It is usually made of polypropylene or ABS, has a one-inch inlet, and works well at an operating pressure of about 2 to 3 bars. The spray radius is approximately 1.2 meters. It distributes water evenly, prevents dry spots on the packing, and enhances cooling efficiency. It is mostly used in industrial cooling towers such as power plants, petrochemical plants, and large factories. If needed, I can also guide you on selecting the size or number of nozzles.

This level of accuracy is especially important for research laboratories, pharmaceutical industries, chemical production, and calibration centers. The device's measurement system is designed to detect even very small pH changes and provide stable and reliable results. ORP Measurement for Monitoring Oxidation-Reduction Reactions Unlike many ordinary pH meters, TES-1380K also has the capability to measure ORP (Oxidation Reduction Potential). ORP measurement is very important in water treatment industries, swimming pools, food industries, pharmaceutical industries, and chemical processes because this parameter indicates the oxidizing or reducing power of the solution. Precise ORP control helps users better evaluate the performance of disinfectants, the status of chemical reactions, and the quality of various processes. Automatic Temperature Compensation (ATC) with TES ORP Meter One of the factors that can affect pH measurement results is changes in solution temperature. TES-1380K is equipped with an Automatic Temperature Compensation (ATC) system that automatically applies the effect of temperature changes on measurement results by simultaneously measuring the solution temperature. Also, if needed, Manual Temperature Compensation (MTC) is available so the user can apply desired settings according to test conditions. This feature increases measurement accuracy and reduces errors caused by temperature variations. Smart and Fast Calibration of TES 1380 To maintain measurement accuracy, pH meters must be calibrated periodically. TES-1380K supports multi-point calibration and can automatically recognize standard buffer solutions. This feature not only speeds up calibration but also reduces user error probability, ensuring the device always measures with maximum accuracy. Simple and fast calibration makes this model a suitable option for daily use in quality control laboratories. Data Recording and Management with TES pH Meter One of the important features of TES-1380K is the ability to store measurement data. The device can manually store 99 records and also offers the capability to continuously record up to about 3000 data points. This feature is very useful for tests that require recording pH or ORP changes over time and enables complete documentation of results. Computer Connectivity and Professional Data Management In many laboratories and production lines, simply viewing the pH value is not enough; measurement data must be stored for reporting, documentation, or further analysis. TES-1380K is equipped with an RS-232 interface that enables data transfer to a computer. Using the device's dedicated software, users can view, archive, and analyze recorded data and prepare documented reports on pH, ORP, and temperature trends. This capability is especially useful in pharmaceutical, food industries, research centers, and quality control laboratories where data recording according to management standards is important.
