Physico-chemical Water Treatment Processes
Physico-chemical treatment may constitute a single stage in the wastewater treatment process or be added as an additional treatment process during pre-treatment (to improve the biodegradation of wastewater in the biological process and secondary treatment (such as polishing). Physico-chemical processes have been implemented for over 100 years.
Physico-chemical treatment of wastewater focuses primarily on the separation of colloidal particles. This is achieved through the addition of chemicals (called coagulants and flocculants). These change the physical state of the colloids allowing them to remain in an indefinitely stable form and therefore form into particles or flocs with settling properties (3, 4 and 5).
Innovative physico-chemical treatment of wastewater
Innovative physico-chemical treatment of wastewater incorporating Moringa oleifera seed coagulant. A water extract of M. oleifera seed was applied to a wastewater treatment sequence comprising coagulation–flocculation–sedimentation–sand filtration. The study was laboratory based using an actual wastewater.

Recent advances in removal of lignin from paper industry
3.1. Physico-chemical methods. The implementation of different physico-chemical techniques has been done for the removal of lignin from pulp and paper industry wastewater such as, ozonation, filtration, coagulation and precipitation, adsorption, reverse osmosis and advance oxidation process etc. 3.1.1. Coagulation and precipitation
This study investigates the level of wastewater pollution by analyzing its chemical characteristics at five wastewater collectors. Samples are collected before they discharge into the Danube during a monitoring campaign of two weeks. Organic and inorganic compounds, heavy metals, and biogenic compounds have been analyzed using potentiometric and spectrophotometric methods.

Wetlands for Wastewater Treatment. Constructed wetlands (CWs) mimic the simultaneous physical, chemical, and biological processes occurring in natural wetlands for wastewater treatment purposes (Wu et al., 2025).This section summarizes studies performed on the use of CWs for water and wastewater treatment to remove a variety of pollutants.
Use of natural coagulants for industrial wastewater treatment
Industrial effluents are a menace to the environment and the fact that their characteristics vary from industry-to-industry only adds to the complex challenge they offer to the engineers and scientists. Resource-efficient and environment-friendly solutions to this hazard are a call of the hour. Coagulation, by synthetic chemicals, has been used as a cost-effective and efficient method for
Cleanmaxx® is one of the effective biological wastewater treatment solutions. It is a specialised heterogenous concentrated consortium of uniquely functional bacteria with a high proliferative capacity and tenacity to withstand hostile effluent waters.
Physico-Chemical Analysis of Electroplating Industrial
The wastewater treatment system in Indian industries is recommended to be essentially installed to meet the waste water discharge norms, but presently only 10% of the waste water generated is treated and the rest of untreated water is discharged as it is into nearby water bodies (Mehta and Bhardwaj, 2012).The use of industrial effluents for
The removal of estrogens (estrone E1, estradiol E2, and ethinylestradiol EE2) was studied in various municipal wastewater treatment processes equipped for nutrient removal. A biological degradation model is formulated, and kinetic parameters are evaluated with batch experiments under various redox conditions. The resulting model calculations are then compared with sampling campaigns performed

- What is trichloroisocyanuric acid used for?
- Trichloroisocyanuric acid (TCCA) is a versatile and efficient reagent for chlorination and oxidation reactions. It was effectively used to synthesize many classes of compounds such as: chlorinated arenes, N -chloramines and amides, α-halo-carbonyl compounds, benzyl chlorides, esters, carboxylic anhydrides, and amides.
- What is trichloroisocyanuric acid C3Cl3N3O3?
- Trichloroisocyanuric acid, referred to as TCCA, is a chloroisocyanuric acid compound with the chemical formula C3Cl3N3O3. It usually exists in the form of white crystalline powder, granules or tablets, and has a strong chlorine odor. Its effective chlorine content can reach more than 90%, and its solubility in water at 25 degrees is 1.2 grams.
