“…High turbidity water is cloudy or muddy, while water with low turbidity is clear. 29 The phase transition behavior of a WPET aqueous solution is first investigated by turbidity measurements, as shown in Figure 3a. The turbidity of all three WPETs showed an increasing trend with the increasing WPET concentration.…”

Amphiphilic polymer water-dispersed polyester (WPET) has an important application value in the textile field. However, due to the potential interactions among water-dispersed polyester (WPET) molecules, the stability of their solution is susceptible to external factors. This paper focused on the self-assembly properties and aggregation behavior of amphiphilic water-dispersed polyester with different contents of sulfonate groups. In addition, the effects of WPET concentration, temperature, and Na+, Mg2+, or Ca2+ on WPET aggregation behavior were systematically investigated. The results show that compared with the low sulfonate group content of WPET, the high sulfonate group content of the WPET dispersion has higher stability with or without a high electrolyte concentration. In contrast, dispersions with low sulfonate group content are very sensitive to electrolytes and aggregate immediately at low ionic strength. WPET concentration, temperature, and electrolyte play important and complex roles in controlling the self-assembly properties and aggregation behavior of the WPET. The increase in WPET concentration can promote the self-assembly of WPET molecules. With the increase in temperature, the self-assembly properties for water-dispersed WPET are significantly reduced, resulting in enhanced stability. In addition, the electrolytes Na+, Mg2+, and Ca2+ in the solution can significantly accelerate the aggregation of WPET. This fundamental research on the self-assembly properties and aggregation behavior of WPETs can be used to effectively control and improve the stability of WPET solutions and provide guidance for the prediction of stability for WPET molecules not yet synthesized.

Aheri tehsil of Gadchiroli district in the Indian state of Maharashtra is located on the bank of the Pranhita River, a side stream of the Godavari River. In the present study, total five villages from Aheri taluka were selected to collect groundwater samples. A total number of 25 samples were collected, where five samples represent each village. This study is concerned with physicochemical parameters mainly electrical conductivity, total dissolved solids, temperature, chloride, fluoride, total hardness, pH, nitrate, alkalinity, iron and turbidity to analyse groundwater quality. Out of 25 samples, eight samples of water were detected to be unfit for consumption. Hence, some remedial measures are suggestible. The study revealed the associations among all physicochemical parameters by correlation coefficient analysis.

We present an investigation of tofu wastewater that contains organic substances that can cause rapid microbial growth in the water. It can lead to a decrease in oxygen levels. In addition, tofu wastewater also contains suspended substances that cause turbidity. This study aims to evaluate changes in pH, temperature, and efficiency of reducing turbidity & chemical oxygen demand (COD) of tofu wastewater using a combination of electrocoagulation and ozone. This research method was carried out on a laboratory scale using tofu wastewater. The ozone generator is used for ozonising tofu wastewater and an acrylic batch type electrochemical reactor. The electrode material used for the anode and cathode is made of aluminum and iron sheets. There were also differences in the highest turbidity removal of 78.3% at the 60 th min when the wastewater was treated using a combination of electrocoagulation followed by ozone. The highest COD removal of 51.9% resulted from the treatment of tofu wastewater using ozone for 60 min. The initial temperature was 27.6°C then increased by 28.1°C (1.8%). Combination of electrocoagulation followed by ozone was more effective in reducing pollutants in tofu wastewater.
