The role of zeolites in wastewater treatment of printing inks
The adsorption of residual organic pollutants from flocculated printing ink wastewater onto several synthetic zeolites was investigated as a finishing method for additional reduction of TOC. The nonselective removal of total organic content was studied. The amount of adsorbed organics was largest for ZSM-5 and NH4-Beta while the other zeolites studied showed lower efficiency, suggesting that

Treatment of the actual water-based printing ink wastewater by Fenton process combined with coagulation was conducted in this study. In Fenton process, 92.4% of COD and 86.4% of color removal could be obtained after 30 min settling time at the following conditions: pH 4, dosages of H 2 O 2 and FeSO 4 were 50 mg/l and 25 mg/l, respectively.

Printing industries generate ink wastewater with high concentration of color and COD, which contains recalcitrant organics including pigment, dye, varnish oil, solvent, and additives. There are many ways dealing with printing wastewater, for example, physical-chemical treatment method, biological method.

- Is polyaluminum chloride a good coagulant for water treatment?
- Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water [ 6 ].
- What is poly Aluminium chloride?
- This article delves into the chemical properties, uses, and safety considerations of poly aluminium chloride, while also examining its pivotal role in the water treatment industry. Poly aluminium chloride, commonly abbreviated as PAC, is a complex chemical compound used primarily as a coagulant in water purification.
- Why is poly Aluminium chloride used in water treatment?
- The primary use of poly aluminium chloride in the water treatment process is to remove impurities and clarify water. This is achieved through a process known as coagulation, where PAC helps to bind particles into larger aggregates that can be easily removed.
- Do polyelectrolyte composite coagulants improve coagulation performance?
- El Foulani, Mohamed. Tahiri & Polyaluminum chloride (PAC)/natural polyelectrolyte composite coagulants have received considerable attention recently due to their exceptional properties in drinking water treatment. However, the criteria for selecting polyelectrolytes grafted into the PAC to improve coagulation performance are not yet well defined.
