The textile industry is one of the most popular industries in Indonesia. Although it’s giving a positive value towards economic value, it also contributes a bed effect towards environmental quality. One of those industries is small-scale laundry industry located in Kelurahan Sukabumi Selatan, West of Jakarta. The lack of land and money, most of the jeans laundry industry throws away their wastewater straight to the river system without any process. The present study describes the application plastic media called bio-ball as a biofilter supporting media for treating of jeans laundry industry wastewater using combined anaerobic and aerobic process. The type of reactor that is used in this research is a continuous flow biological reactor which has total volume 195 litter and divided into 5 zones, i.e. presedimentation , 2 anoxic zone, aerobic zone and post sedimentation zone. Reactor effluent is recirculated into presedimentation zone with hydraulic recycle ratio (HRR) 1:1. Seeding is done in a natural way by directly flowing the domestic wastewater into reactor with retention time 72 hours, until a biofilm layer is formed on the surface of bio-ball media. Acclimatization is done gradually by replacing domestic with laundry jeans wastewater in 72 hours retention time, until domestic wastewater was 100 % replaced, The main research were conducting by continuous operation under condition 72 hours, 48 hours and 24 hours retention time. The result of experiment shows that within the combined anaerobic and aerobic process using bio-ball plastic media under conditions 1 - 3 days retention time, the removal efficiency of COD 78 – 91 %, BOD 85 – 92 %, Total Suspended Solids (TSS) 80 – 93 %, and Colour 48 – 57 % respectively.  The longer retention time has resulted in higher removal efficiency

By using an advanced anaerobic filter-contact aeration Gappei-shori Johkaso (AFAJ), a small-scale wastewater unit used in Japan, experiments of the treatment of the wastewater mixed with domestic wastewater and disposer wastewater which came from washing water of crushed garbage by disposer were made. After the introduction of disposer wastewater into domestic wastewater, BOD, TN and SS loads increased to 1.7 times, 1.1 times and 1.7 times, respectively. Results showed that in the 5-person-use type AFAJ, no remarkable decrease appeared to the BOD and SS removal efficiencies after introduction of disposer wastewater into domestic wastewater, however, TN removal efficiency decreased significantly. As a result, effluent BOD and TN concentrations were much higher than 20 mg·l−1. On the other hand, the 7-person-use type AFAJ, whose volume was 35 % bigger than that of the 5-person-use type AFAJ, could treat the above wastewater to be less than 20, 10 and 20 mg·l−1, respectively. In addition, it was shown that not many changes took place in the kinds and occurrence frequencies of protozoa and metazoa after the addition of the disposer wastewater, which suggested that the addition of disposer wastewater had increased the BOD and SS loads while it did not lead to much change in the component of the domestic wastewater.

The authors have developed what we call the submerged iron contactor process as a simple and inexpensive phosphorus removal method for small-scale plants disposing of domestic wastewater and household wastewater treatment tanks. In this method iron contactors are submerged in biological treatment tanks, where phosphate anions in wastewater are combined with iron cations produced through corrosion of the contactors, and the compound thus produced is precipitated and removed together with biological sludge. In these studies, laboratory experiments were made on the contact aeration process combined with the above-mentioned method, and the following findings were obtained. (1) It is desirable to treat wastewater by making use of corrosion by sulfate-reducing bacteria instead of corrosion by oxygen dissolved in wastewater, to conduct a stable phosphorus removal by this combined method. (2) The corrosion rate of iron contactors is affected by the volumetric loading of BOD in the tanks where they are submerged. (3) Assuming that an iron contactor continues to suffer corrosion evenly all over the surface when our combined method is applied, it is estimated that the corrosion rate is about 1mm or less in 30 years.

A laboratory study was conducted to determine the feasibility of batch activated sludge reactor for treating pineapple wastewater and to examine the effects of bioaugmentation on treatment performance. The experimental set-up consists of eleven batch reactors. Activated sludge obtained from a wastewater treatment plant treating domestic wastewater was used as seed for the reactors. Synthetic pineapple wastewater was used as feed for the reactors. The eleven reactors were arranged to evaluate the total organic removal, nitrification, and sludge production by bioaugmentation process. Three major factors considered were influent organic loading, ammonia-nitrogen, and dosage of bacterial-culture-product addition. Removal of TOG (total organic carbon), sludge production in terms of SS(suspended solids), and ammonia-nitrogen removal variation are used as evaluation parameters. The TOC removal efficiency after the end of a 48 hour reactor run, for influent TOC of 350.14 to 363.30 mg/l, and 145.92 to 169.66 mg/l, was 94.41 to 95.89%, and 93.72 to 94.73% respectively. Higher organic removal was observed in the bioaugmented reactors with higher organic loading. The better organic removal efficiency in the bioaugmented reactors was probably due to activities of bacteria added. The test results also indicated that sludge yield was enhanced by the bacteria additive and high bacteria dosage produced less sludge. Bioaugmentation was observed to be a suitable alternative for enhancing the biological treatment of pineapple wastewater.

Dairy wastewater (DWW) contains large amounts of mineral and organic compounds, which can accumulate in soil and water causing serious environmental pollution. A constructed wetland (CW) is a sustainable technology for the treatment of DWW in small-medium sized farms. This paper reports a two-year study on the performance of a pilot-scale horizontal subsurface flow system for DWW treatment in Sicily (Italy). The CW system covered a total surface area of 100 m2 and treated approximately 6 m3 per day of wastewater produced by a small dairy farm, subsequent to biological treatment. Removal efficiency (RE) of the system was calculated. The biomass production of two emergent macrophytes was determined and the effect of plant growth on organic pollutant RE was recorded. All DWW parameters showed significant differences between inlet and outlet. For BOD5 and COD, RE values were 76.00% and 62.00%, respectively. RE for total nitrogen (50.70%) was lower than that of organic compounds. RE levels of microbiological parameters were found to be higher than 80.00%. Giant reed produced greater biomass than umbrella sedge. A seasonal variation in RE of organic pollutants was recorded due to plant growth rate Our findings highlight the efficient use of a CW system for DWW treatment in dairy-cattle farms.
