This article shows the possibility of using reagent-adsorbent compositions, i.e. charred defecate obtained at 600 °C and activated bentonite of the Askamar deposit in a ratio of 1:5. It was found that with the use of reagent-adsorbent compositions it will allow to purify wastewater from oil and fat production to pH-7.2 and transparency of 0.44, and also the water hardness is reduced from 17 mEq / l to 4.0 mEq / l, which allow the recycling of wastewater for technical needs.

Activated Bentonite

One of the main problems encountered in biological waste water treatment plant of papermills is poor settling of activated sludge in secondary sedimentation tanks. In many cases, activated sludge volume indices stay above 150 ml/g. Moreover, bulking of sludges in activated sludge plants of papermills is more frequent than usual. Bulking sludge is characterized by excessive growth of filamentous microorganisms. In a lab-scale activated sludge plant, tests were made to improve the settling of activated sludge by adding the following chemicals: Lime, alkaline activated bentonite, powdered lignite coke, polyelectrolytes used as flocculants. The findings reveal that dosage of the above additives actually gives improved sedimentation. Moreover, biochemical degradation becomes more effective if bentonite and powdered lignite coke are added. Test results are evaluated to determine the extent to which settling of the activated sludge and plant efficiency are improved, taking into account operational and waste water parameters. Using lime, bentonite, lignite coke or polyelectrolytes is an economic method of fighting or preventing acute or permanent problems caused by bulking sludge and high sludge volume indices.

The Palm Oil Factory produces wastewater containing high enough Phosphor (P). High levels of Phosphor can cause pollution load for the environment, so it needs to be lowered. The decrease of this content can be done by adsorption process using bentonite as adsorbent. The purpose of this research is to determine the absorption of activated bentonite to the absorption of Phosphor contained in waste water. Phosphor measurements were performed using the UV-vis Spectrophotometric Instrument. Bentonite was activated using HCl 1.6 M. Characterization of bentonite using X-ray diffraction (XRD) and Scanning Electron Microscopy with Energy Divertive Spectroscopy (SEM-EDS). The results showed that bentonite was able to adsorb Phosphor contained in the waste water of Palm Oil Factory, with adsorption capacity> 90%. Activated Bentonite has greater power capability than natural bentonite.

Textile Waste Water

Waste water from the textile industry is one of the major sources of contamination causing serious health problems. In textile waste water, dyes are the main pollutant. In this research work textile waste water was treated with various organic acid-activated clays to remove the dyes. Pink Azo dye was selected as a component to remove from waste water. Adsorbent selected was bentonite clay and was activated by acids such as phosphoric, acetic, oxalic, and citric acids. Adsorbent characteristics have been analyzed through infrared spectroscopy (FTIR) and Scanning Electron Microscope (SEM) while the removal of dye at various temperatures has been analyzed through Ultraviolet (UV) analysis. It was observed that the bentonite clay-treated with phosphoric acid had relatively maximum capacity to remove the dye while the clay treated with oxalic acid got minimum capacity to remove the dye from same waste water.

Contamination Levels

The need for deinking mills to reduce their fresh water consumption has resulted in higher loads of various contaminants in the process water. Lower recovered paper quality also leads to higher contamination levels in the mills. This higher load has an influence on achievable target brightness. The objective of the work was to determine and explain the main reasons for relatively poor deinked pulp quality or poor deinking potential based on the influence of recovered paper composition and process water quality. The process water parameters significantly affect the deinking potential of recovered paper. The test results showed the negative effects of increased water hardness. For standard recovered paper mixtures, flotation selectivity is higher with increasing flotation pH-value. Good results were realized for standard recovered paper with low hardness, low surface tension, and high pH-value. The results for recovered paper containing flexo newsprint could be slightly improved with low hardness, low surface tension, and low pH-value. The results of the test program using design of experiments showed interacting effects of pH-value and surface tension on luminosity and flotation selectivity.

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.
