Abstract:

Pilot studies were conducted at Liu-Du water treatment located in Keelung, Taiwan. Raw water was first treated by conventional coagulation- sedimentation-filtration (CSF) processes, and then pumped into the pilot plants. For the pilot plants, both ozone/GAC and ozone/UF processes were operated simultaneously for NOM removal comparisons. Both systems were controlled at the same operating conditions with ozone dosing of 4.5, 6.0 and 9.0 mg/L. The results demonstrate that both ozone/UF and ozone/GAC processes can enhance NOM removal after the CSF process. More NOM was removed by the Ozone/GAC pro

Abstract:

There has been an increase in the use of antibiotics by the aquaculture industry in marine aquaculture for the prevention of diseases in fish. Antibiotics in the water discharged into the sea without treatment can cause disturbances to the marine ecosystem. Therefore, there is a need for research on how the removal of antibiotics used in aquaculture can be achieved. In this study, the removal of two types of antibiotics (florfenicol, FF, and oxolinic acid, OA) used in the aquaculture industry, by ozonation, was evaluated. Currently, there is a lack of research studies on FF and OA removal from

Abstract:

Treatment of real yarn dyed wastewater using hybrid electrocoagulation (EC)-ozonation process has been carried out to solve the non biodegradable wastewater. The work aimed to treat the real yarn dyed wastewater under different ozone concentration and agitation speed and to estimate the kinetic parameter of ozonation. The effect of ozone concentration, agitation speed were studied to give the best performance of color and chemical oxygen demand (COD) removal. The result indicated 38.12% of COD removal and 92.53% of color removal using EC with Al/Al electrodes for 10 minutes. The effluent was p

Abstract:

Ozone in aircraft cabin can bring obvious adverse impact on indoor air quality and occupant health. The objective of this study is to experimentally explore the ozone removal performance of flat-type catalyst film by loading nanometer palladium on the activated carbon fibers (Pd/ACFs), and optimize the configuration of ozone converter to make it meet the design requirements. A one-through ozone removal unit with three different Pd/ACFs space was used to test the ozone removal performance and the flow resistance characteristic under various temperature and flow velocity. The results show that t

Abstract:

Ozone is a kind of hazardous gas in indoor areas and needs to be removed in order to protect the human respiratory system. Previous methods include physical adsorption, thermal treatment, electromagnetic radiation removal, catalysis and photocatalysis. However, they all have limited effects. This research introduced a novel milestone to remove indoor ozone by utilizing visible light photocatalysis technique under ambient condition. The modified sol–gel method was applied to prepare photocatalysts, strontium titanate (SrTiO3) and rhodium-doped strontium titanate (SrTiO3:Rh). In addition, the Sr

Abstract:

A pilot-scale experiment is carried out for treating mixed wastewater containing pharmaceutical wastewater (PW) and domestic wastewater (DW), by a process that is a combination of hydrolysis acidification-ozone-modified anaerobic–anoxic–aerobic-ozone (A2/O) (pre-ozone) or hydrolysis acidification-modified A2/O-ozone (post-ozone). The effects of different mixing ratios of PW and DW and pre-ozone treatment or post-ozone treatment on the removal of nitrogen and phosphorus and chemical oxygen demand (COD) are compared and studied. The optimal ratio of PW in mixing wastewater is 30%, which has the

Abstract:

The study investigates the effect of partial ozonation of textile wastewater, both at the inlet (pre-ozonation) and the outlet (post-ozonation) of biological treatment, for the optimization of COD and color removals, both typical polluting parameters associated with the textile industry. Pre-ozonation provides at optimum contact time of 15 minutes 85% color removal, but only 19% COD reduction. Removal of the soluble inert COD fraction remains at 7%, indicating selective preference of ozone for simpler compounds. Post-ozonation is much more effective on the breakdown of refractory organic compo

Abstract:

In this study, the micro-polluted water of a reservoir filled with Yellow River water in Shanxi was used as the raw water. The removals of chemical oxygen demand (CODMn), ammonia nitrogen, petroleum substances, and volatile phenol were investigated by ozone-activated carbon process. Results showed that ozone-activated carbon process had a good removal of the pollutants mentioned above. The optimum dosage of ozone for each pollutant was 2.0 mg/L, 2.5 mg/L, 3.0 mg/L, 3.0mg/L, with the corresponding removal efficiency of 59.36 %, 88.01%, 79.31%, and 88.16%, respectively.

Abstract:

The Dissolved Air Flotation (DAF) process is very effective in removing low density floc particles for drinking water treatment. It is especially well known in removing turbidity and algae by flotation process. The micro-bubbles in the DAF process pick up small flocs, thereby turbidity materials and floated algae are removed efficiently. When air is substituted by ozone in the DAF process, the removal rates of water quality parameters are highly enhanced including turbidity and algae. The turbidity removal rate is enhanced by 1.1% while the removal rate of THMFP is increased by 11.7%. Other pa
