Pilot plant results of anaerobic treatment using granular biological fluidized bed treatment for a number of industrial wastes is presented. Wastes containing from 5,000 to 54,000 mg/ℓ, were treated with 65 to 95 percent COD removal in 0.3 to 4.9 days hydraulic detention time. Organic loadings of 3 to 38 kg COD/m3-day were used. An energy comparison showed anaerobic treatment to produce a positive energy balance compared to an energy need for comparable activated sludge treatment.

Anaerobic Environment

Over the past decades, anaerobic biotechnology is commonly used for treating high-strength wastewaters from different industries. This biotechnology depends on interactions and co-operation between microorganisms in the anaerobic environment where many pollutants’ transformation to energy-rich biogas occurs. Properties of wastewater vary across industries and significantly affect microbiome composition in the anaerobic reactor. Methanogenic archaea play a crucial role during anaerobic wastewater treatment. The most abundant acetoclastic methanogens in the anaerobic reactors for industrial wastewater treatment are Methanosarcina sp. and Methanotrix sp. Hydrogenotrophic representatives of methanogens presented in the anaerobic reactors are characterized by a wide species diversity. Methanoculleus sp., Methanobacterium sp. and Methanospirillum sp. prevailed in this group. This work summarizes the relation of industrial wastewater composition and methanogen microbial communities present in different reactors treating these wastewaters.

Research Stage

Sidoarjo Regency is one of the supporting districts of East Java province. Sidoarjo Regency is experiencing rapid progress because of the development and potential in trade and industry. One of the industries often found in Sidoarjo Regency is tofu factory. The rapid number of tofu craftsmen industry has caused an increase in the volume of liquid waste which also flows into water bodies. The purpose of this study was to determine the reduction in BOD and COD levels for the tofu factory wastewater treatment in the Sepande area, Sidoarjo Regency using a contructed wetland with Typha latifolia as the remediator. The research stage will be carried out using a laboratory scale using acclimatization as the adaptation stage of Typha latifolia and a crontructed wetland reactor as phytoremediation processing. Based on the results and discussion, it can be concluded that there was a decrease in BOD and COD levels in the tofu industrial wastewater in Sidoarjo using the Constructed Wetland system. The percentage reduction in BOD content was greatest in soil media with 3 stems of Typha latifolia plants and a detention time of 4 days of 72%. While the largest percentage reduction in COD levels was in soil media with 2 stems of Typha latifolia plants and 4 days of detention time of 84%.

High Treatment

One of the most recent and progressive reactor principles used in anaerobic wastewater treatment technology is a vertical compartmentalization, which is used in the USSB (Upflow Staged Sludge Bed) reactor. Thanks to its specific design and features the operation of such a reactor can be very flexible. Examples are given showing tested alternatives of operation with combined wastewater and sludge treatment. A high treatment efficiency and a very low specific sludge production was achieved with the operation of a technological system consisting of a USSB reactor and an aerobic biofilm reactor. In the USSB reactor wastewater and surplus sludge treatment can not only be combined but also anaerobic pretreatment and biological denitrification.

The use of industrial wastes as alternative adsorbents for wastewater treatment is proposed. The effective concentration of the adsorbent was determined experimentally. The results of a study of the intensification of biological wastewater treatment using activated carbon and a pulverized coke fraction are presented. The efficiency of treatment in terms of "chemical oxygen demand" during the intake of highly concentrated sewage sludge with the use of an alternative adsorbent averaged 85 %. In the biosorption system, the conservation of the species diversity of the biocenosis of activated sludge and its purifying ability was noted. In the biological treatment system, purification efficiency was recorded on average 16 % less and destabilization of the system as a whole. The carried out researches prove expediency of use of adsorbents, including production wastes, for intensification of biological wastewater treatment in aero tanks.

Fluidized Bed Process

Significant amounts of nitrogenous organic compounds found in industrial wastewaters can have major deleterious effects on the environment and public health; therefore, the removal of these compounds has become an essential component in industrial wastewater treatment. In this work the biodegradability of diisopropylamine and monoethylamine - compounds commonly found in petroleum refinery wastewater - was investigated under oxic and anoxic conditions. Biological fluidized bed reactors were employed in the investigation of single-stage carbon oxidation and nitrification with the amines and phenol as the compounds targeted for removal. Complete carbonaceous oxidation was achieved with a 50% nitrification rate. The feasibility of utilizing the amines and phenol as the organic carbon source for denitrification in an anoxic biological fluidized bed process was also examined. Carbon removal under anoxic conditions was greater than 85% at carbon loading rates less than 0.05 mg TOC/mg biomass-day and decreased to 60% at higher loading rates. Over the range of loading rates tested, the average ratio of mg TOC removed to mg NO3−-N utilized was observed to be 1.26.
