Wastewater-Primary Treatment
Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...

Chitosan use in chemical conditioning for dewatering municipal-activated sludge
This work aims to evaluate the potential use of chitosan as an eco-friendly flocculant in chemical conditioning of municipal-activated sludge. Chitosan effectiveness was compared with synthetic cationic polyelectrolyte Sedipur CF802 (Sed CF802) and ferric chloride (FeCl3). In this context, raw sludge samples from Beni-Messous wastewater treatment plant (WWTP) were tested. The classic jar test ...

How Chemicals Are Used in Wastewater Treatment
There are many different steps to process wastewater, but one of the most important is using the chemical dosing system. This system involves a chemical feed station delivering a chemical substance into sewage, sludge, and foul water. Pumping systems like these at wastewater treatment plants usually consumes between 10% and 15% of the plant’s energy, making this process a significant part ...

Performance of four polyelectrolytes as flocculation aids in the primary treatment of textile effluents
Samples of textile effluents were subjected to physico-chemical treatment using alum, Polyaluminium Chloride (PAC), and different anionic and cationic acrylamide copolymers. Except for alum, all chemicals were tested individually. Combinations of alum and PAC with different anionic and cationic polyelectrolytes were also tested. Results indicated the anionic polyelectrolyte to be the best polymer ...

Corrugator Wastewater Reuse Results Containerboard Packaging
Corrugator Wastewater Treatment Success Corrugator Wastewater Reuse The previous wastewater treatment was composed of the following chemicals: an acidic coagulant, caustic for pH adjustment, and an anionic polymer made down to 1% solution. The facility used 3-4 gallons of coagulant, 2-3 gallons of caustic, and 2-3 gallons of anionic flocculant (at a 1% solution) at a cost of $50 per ...

Whitepaper: Chemical-physical Water Treatment, Filtration and Flocculation
Introduction In water treatment plants chemical-physical processes play an essential part in the process chain. They are successfully employed in the pre- and post-treatment of waters of different origins, as well as of other process liquids. In this regard the removal of particles by filtration is a central step. Classical filtration processes are used for particles ranging from 1 μm to 100 ...

Reduction dye in paint and construction chemicals wastewater by improved coagulation–flocculation process
A coagulation–flocculation process was applied to wastewater of paint and construction chemicals producing factory in Turkey. Ferric chloride was used as coagulant and several natural based materials, namely limestone, pumice, sepiolite, bentonite and mussel shell were used as flocculant aids. The effects of dosage of flocculant aids on the pH, color and electrical conductivity of wastewater ...

Veolia upgrades water treatment plant for Mozambique bottling plant
Veolia Water Technologies South Africa recently commissioned a new water treatment plant for Refrigerantes Spar Mozambique Lda, a bottling plant contracted to bottle Coca-Cola and other soft drink products in Mozambique. Veolia replaced the entire water treatment plant, which treats a nominal flow of 15 m3/hour (with a peak of 20 m3/hour) of water from the municipal bulk supply, and a ...

Top 5 Advantages of Advanced Electrocoagulation Water Treatment
Coagulation is a common practice in water and wastewater treatment processes, often used prior to filtration or sedimentation. Particles in the solution have a difficult time settling due to their common charges, which cause them to repel one another. To combat the repellant forces, the charges of the particles must be neutralized so that the colloids will cling together and precipitate, which ...
