Globally, at least 2 billion people use a drinking water source contaminated with faeces. Contaminated water can transmit diseases such diarrhoea, cholera, dysentery, typhoid, and polio. Contaminated drinking water is estimated to cause 485 000
Chlorine dioxide as a disinfectant - Lenntech
For drinking water treatment chlorine dioxide can be used both as a disinfectant and as an oxidizing agent. It can be used for both pre-oxidation and post-oxidation steps. By adding chlorine dioxide in the pre- oxidation stage of surface water t
Chlorine dioxide (ClO2) is a chemical compound consisting of one chlorine atom and two oxygen atoms. It is a reddish to yellowish-green gas at room temperature that dissolves in water. It is used for a variety of antimicrobial uses, including
Polyethylene terephthalate
Polyethylene terephthalate (sometimes written poly (ethylene terephthalate) ), commonly abbreviated PET, PETE, or the obsolete PETP or PET-P, is the most common thermoplastic polymer resin of the polyester family and is used in fibres for
Polyethylene Terephthalate commonly known as PET or PETE is the mostly used polymer in the world. It is naturally transparent and semi-crystalline plastic used widely for products used in our day to day life. PET polymer is better termed as “Pol
Recycling codes
Recycling codes are used to identify the material from which an item is made, to facilitate easier recycling or other reprocessing. The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic

Certain uses lead to the presence of aluminium in drinking water and foodstuffs. Bauxite is the most important raw material used in the production of aluminium. Bauxite is refined to produce alumina from which aluminium metal is recovered by
- Can cationic-surfactant polyacrylamide be used as a viscosifier in drilling fluid?
- Likewise, Shettigar et al. (2018) designed a cationic-surfactant polyacrylamide as viscosifier in drilling fluid, which showed the improvement of rheology and cutting effect due to the hydrophobic and electrostatic interaction between the surfactant (cetyltrimethyl ammonium bromide) and polymer.
- What is modified polyacrylamide drilling fluid?
- Indeed, modified polyacrylamide drilling fluid has been proven to be of great interest for use in the construction of bored piles and diaphragm walls in recent years. 1. Introduction Drilling fluid is a critical component in exploration and excavation, classified into water-based, oil-based, synthetic-based, and gas-based.
- Can an anionic polymer withstand drilling fluid?
- The fluid loss test on this drilling system found that anionic polymer can resist about 4.5 × 105 ppm of Cl −, 4 × 105 ppm of Ca 2+, and 1.5 × 104 ppm of Mg 2+ at low pH by adding the acidic gas together at 180 °C. Thus, it can withstand the temperature of drilling fluid up to 180 °C.
- Does barite/polyacrylamide nanocomposite affect water-based drilling fluid?
- Roodbari and Sabbaghi (2021) studied the effect of barite/polyacrylamide nanocomposite in the water-based drilling fluid, which showed the incline of its fluid viscosity and the reduction of fluid loss and filter cake thickness. Besides, Kuma et al. (2025) optimised the polyacrylamide-based drilling fluid with the inclusion of hematite.
