Mechanical Mixer

A 40 1 tank reactor, filled to 3 % (v·v−1) with a small size (5-25µm) carrier material and equipped with a mechanical mixer, was used to create a sludge bed system for anaerobic waste water treatment. Solids leaving the tank with the effluent were recycled to the tank from an external settler. Two different substrates were used, fodder molasses diluted with tap water and beet sugar factory waste water. Influent concentrations were 9.3 g COD·1−1 and 4-7 g COD·1−1 respectively, and treatment was performed at 35-37 °C. With the synthetic molasses waste water, an organic load of 5-6 kg COD·m−3·d−1 could be tolerated, with the sugar industry waste water 25 kg COD·m−3·d−1. The difference in loading capacity was ascribed to different types of sludges formed, the molasses waste water resulting in a much more bulky sludge and a lower attainable volatile suspended solids concentration. It was concluded that much care must be exercised before designing sludge bed systems for high loads with unhydrolyzed waste waters.

The main goals for the design of waste water treatment plants are high efficiency, high operational reliability and minimal costs. The challenge to have very low investment costs especially exists for industrial plants which are only in operation for several months every year as e.g. in the beet sugar industry in Central Europe. A case study of an Austrian sugar factory treatment plant shows that using very simple and low-cost structures does not affect the efficiency of the treatment. This factory is also one of the rare cases where biologically treated effluent is recirculated to reduce fresh water consumption. Special emphasis is put on the start-up process, the influence of shock loadings in the influent, and design and operation of the plant.

Operational Costs

An Austrian research project focused on the development of process indicators for treatment plants with different process and operation modes. The whole treatment scheme was subdivided into four processes, i.e. mechanical pretreatment (Process 1), mechanical-biological waste water treatment (Process 2), sludge thickening and stabilisation (Process 3) and further sludge treatment and disposal (Process 4). In order to get comparable process indicators it was necessary to subdivide the sample of 76 individual treatment plants all over Austria into five groups according to their mean organic load (COD) in the influent. The specific total yearly costs, the yearly operating costs and the yearly capital costs of the four processes have been related to the yearly average of the measured organic load expressed in COD (110 g COD/pe/d). The specific investment costs for the whole treatment plant and for Process 2 have been related to a calculated standard design capacity of the mechanical-biological part of the treatment plant expressed in COD. The capital costs of processes 1, 3 and 4 have been related to the design capacity of the treatment plant. For each group (related to the size of the plant) a benchmark band has been defined for the total yearly costs, the total yearly operational costs and the total yearly capital costs. For the operational costs of the Processes 1 to 4 one benchmark (€ per pe/year) has been defined for each group. In addition a theoretical cost reduction potential has been calculated. The cost efficiency in regard to water protection and some special sub-processes such as aeration and sludge dewatering has been analysed.

To protect environment from industrial pollution, strict requirements for waste water treatment are imposed. The purpose of research is to establish an optimal ratio of saturated liquid and meat industry waste water. Research included JCC “Traidenis” waste water treatment system installed in JSC “BHJ Baltic”. Investigations into treated waste water indicated that an optimal ratio of waste water and saturated liquid was 2/1 under duration time of 8 minutes. Efficient waste water treatment made 86% and the ratio of waste water and saturated liquid was 2/1. Santrauka Siekiant apsaugoti gamtą nuo pramoninės taršos, nuotekų valymui keliami vis didesni reikalavimai. Darbo tikslas – nustatyti optimalų skysčio ir oro emulsijos ir mėsos pramonės nuotekų santykį. Nuo skysčio ir oro emulsijos ir nuotekų santykio priklauso nuotekų valymo įrenginių kaina ir eksploatacijos išlaidos. Jei bus pasirinktas netinkamas santykis, nuotekų valymo įrenginiams reikės daugiau priežiūros, o tam prireiks papildomų išlaidų. Tyrimams atlikti pasirinkta UAB „Traidenis“ flotacinė nuotekų valymo sistema, sumontuota UAB „BHJ Baltic“ antrinių žaliavų perdirbimo įmonėje. Atlikus tyrimus nustatyta, kad optimalus skysčio ir oro emulsijos ir nuotekų santykis buvo 2:1. Esant tokioms sąlygoms, pasiektas 86 % valymo efektyvumas.

Sugar Industry X in processing liquid waste from sugar production activities by using Waste Water Treatment Plant (WWTP). As the years of IPAL performance increase, it is necessary to evaluate the effectiveness of IPAL performance. The purpose of this research is to know the treatment of liquid waste in Sugar Industry X. The method used in this research is descriptive observasional. This research uses primary data and secondary data. Primary data were obtained from interview and interim observation of secondary data from processing section in the form of inlet laboratory test result and IPAL outlet. Parameter of result of laboratory test analysis is pH, BOD5, COD, TSS, Sulfide, oil and fat. Sampling is conducted from July to October 2017. The results of this study are the average pH concentration 7. The Sugar Industry X IPAL works effectively in lowering the concentrations of BOD5, COD, TSS, Sulfide, oils and fats. The order of decrease of concentration of parameters are 97,90%; 97.51%; 78.80%; 99.80%; 28.81%. From the evaluation of wastewater at IPAL outlet shows that all parameters have met the quality standard of waste water for sugar industry based on East Java Governor Regulation No. East. 52 of 2014 and Minister of Environment Regulation no. 5 Year 2014.

The research aim is to the treatment of industrial dyeing waste water for the analysis of improved water treatment using natural coagulants. For waste water treatment, natural coagulants such as Strychnos potatorum (nirmali seeds) and Eirchorrnia crassipes (water hyacinth) are used. We have test the various properties of dyeing waste water before and after treatment like pH, sulphates, chlorides, total solids, total suspended solids (TSS), total dissolved solids (TDS), acidity, alkalinity, optimum coagulant dosage (jar apparatus), biological oxygen demand (BOD) and chemical oxygen demand (COD) .The test results showed that natural coagulants produce better results when used alone or in conjunction with the chemical coagulant alum. Since the natural coagulant generates less floc, the cost of sludge treatment is reduced. Water hyacinth outperforms nirmali seed in terms of natural coagulants. Natural coagulants may be used to manage and treat the dyeing waste water, anywhere there is an abundance of it.

Research was conducted to assess the effect of  treated waste water  and dry sludge application on soil contamination by some pathogenic bacteria such as Pseudomonas aeruginosa , Fecal coliform and Fecal streptococci, which used as an indicator organisms for soil contamination by bathogenic bacteria. Composting sludge (T2) and non composting dry sludge (T1) applied to soil  to assess the effect of compost of sludge on the number of pathogenic bacteria and soil contamination . Research consisted to identification and enumeration. The three pathogenic bacteria were examined at the mid and end of cultivation season. Factorial experiment with three replicate, using waste water treatment (W2) as a source of irrigation water, compared with tap water (W1).Composting sludge(T2) and non-composting sludge (T1), added and mixed with soil in three different levels 0, 30 , 60 ton .ha-1 .Pancium milicine  was cultivated in pots weighted 10 Kg of silty clay loam soil. Results showed that the number of pathogenic bacteria Pseudomonas aeruginosa, Fecal coliform and Fecal streptococci. Were increased significantly with soil irrigated with waste water treatment, giving 5.88, 5.48 and 5.37 log cfu g-1dry soil respectively,compared with tap water 4.45, 4.29 and 2.97 log cfu g-1dry soil respectively. Results showed also significantly increment in the number of pathogenic bacteria with increase rate of dry sludge utilized to soil. The rate 60 ton.ha-1 was the highest number of pathogenic bacteria in soil 6.21, 5.78 and 5.24 log cfu g-1dry soil respectively. Results showed reduced in the number of pathogenic bacteria in composting sludge compared with non-composting sludge, with reduced proportion of 9.78 , 6.67 and 8.50 % respectively.
