Catalyst with manganese oxide highly dispersed on granular activated carbon (MnOx/GAC) was fabricated by impregnating GAC in MnCl2 solution and characterized by several techniques. The performance of manganese catalyst was investigated in catalytic ozonation of 4-chlorophenol in water. Manganese catalyst exhibits better efficiency than the original granular activated carbon, due to the synergic effect between activated carbon and manganese oxide. MnOx/GAC, produced by a simple methodin situ, is promising in catalytic ozonation of refractory organic pollutants in waste water.

Vegetable Oil Refining

Five composite samples of waste water were collected from waste water tank of a vegetable oil refining company and were analyzed for physiochemical characteristics, heavy metal and organic pollutants. Physicochemical determinations were done according to standard methods; heavy metals were determined by use of Atomic Absorption Spectrophotometer method while organic pollutants were determined by Gas chromatography system HP 6890 series. Sulphate was determined by vanadomolybdophosphoric acid method while phosphates and chlorides were determined by argentometric method. Results reveal that effluent pH (4.67 ±0.015), salinity (125 ±4.50 %) and BOD5 (17.83 ±1.70 mg/l) were bellow WHO standard whereas TDS (127.7 ±5.77 mg/l), TSS (563.6 ±3.15 mg/l) and COD (3959 ±3.8 mg/l) were above WHO standards. Heavy metal pollution index (0.31) showed no multi-element contamination arising from effluent. The degree of contamination (1.84) showed that the effluent has a moderate polluting potential. Lower molecular weight PAHs showed a significant difference even though most of the organic compounds in vegetable oil refinery wastewater showed good biodegradability that varied weekly. Therefore there is either no treatment or an in effective treatment of the effluents. This could result to serious environmental problems in the near future.

Water Treatments

Combined biological AOP system, or CBA, are increasingly being used in Indonesia to treatment hospital waste water, that are otherwise difficult to treatment in conventional methods. CBA catalytic ozonation are now used for over 579 hospitals, making this tool a major phenomenon for high adopt hospital waste water treatments in Indonesia, and one that has experienced great expansion over the past three years. The question of whether the CBA is a good or a bad tool for the treatment hospital waste water depends on many parameters. To respond to this question, it is necessary to investigate on operating conditions, but it is also very important to gather more data and conduct further research on treatment efficiency and energy. In this paper, we examined and discuss to gain a better understanding of the CBA environmental technology and of its impacts. About 100 CBA Full-scale Hospital waste water treatments have been investigated, and it was in Indonesia from eight provinces. CBA demonstrate good removal efficiency of macro-pollutants from hospital waste water and meet the requirements as per LH R.I. Number 5 Year 2014 on Wastewater Quality Standard and LHK R.I. Number P.68 / Menlhk / Setjen / Kum.1 / 8/2016 Concerning the Quality Standards of Domestic Waste Water. Various parameters of macro-pollutants such as pH, temperature, TDS, TSS, BOD 5, COD, oil fat, and MBAS also amonia nitrogen and total coliform were analysed to identify the performance of CBA. We obtained the average energy consumption per cycle is 0.504 kWh, capacity V m3/hours which treatment cost Rp 1.478/m3 and 60,96%-94,00% removal efficiency of macro-pollutants. CBA catalytic ozonation reported here is very efficient and environmental friendly for treatment hospital waste water.
