Preparation of sorbents containing ettringite phase from concrete sludge and their performance in removing borate and fluoride ions from waste water

Study aims to eliminate fluoride from treated waste water or ground water through adsorption technique by using Activated Diatomaceous Earth as a sorbent. Study found that there is no change in pH and TDS, but the concentration of Fluoride ions reduced. The most elimination potential of 71.97 mg/kg turned into achieved for activated diatomaceous earth with particle sizes of 0.075-0.425 mm. The absorbance capability of diatomaceous earth (DE) is 20.73% when used as a filtration media. In this analysis, activated diatomaceous earth was used as an adsorbent in a fixed-mattress column adsorption system for DE fluoridation of water. The XRD, BET surface area, FTIR, XRF, Scanning Electron Microscopy (SEM), and pH Point of Zero Charges (pHPZC) evaluation had been executed for adsorbent to explain the mechanisms of absorption and fluoride elimination. The Bradley equation was used to calculate the isothermal data and adsorbent dose. The statistical analyses were performed using Langmuir and Freundlich equations.

Height Data

System The process of counting and storing in a manual water reservoir analysis has a high percentage of error rate compared to an automated system. In a company industry, especially in the WWT (Waste Water Treatment) section, it has several reservoir tanks as stock which are still counted manually. The ultrasonic sensor is placed at the top of the WWT tank in a hanging position. Basically, to measure the volume in a tank only variable height is always changing. So by utilizing the function of the ultrasonic sensor and also the tube volume formula, the stored AIR volume can be monitored in real time based on IoT using the Blynk application. From the sensor, height data is obtained which then the formula is processed by Arduino Wemos and then information is sent to the MySQL database server via the WIFI network.
