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.

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.

The Citarum River is the longest river in West Java. The river participates in the development of the Indonesian economy by 20% of GDP (Gross Domestic Product). In 2018, the citarum river ecosystem structuring survey team found 31 factories in the Bandung Regency region that dumped the waste produced directly into the Citarum River, one of which was the textile industry. In the production process the textile industry uses textile dyes containing azo dyes. The compound has the potential to produce aminobenzen or aniline which causes pollution. The lack of a communal Waste Water Treatment Plant (IPAL) and improper location is a factor that causes the industry to dispose of production waste water directly into the Citarum River. This study aims to support government activities in improving the Citarum River by designing a Decision Support System (DSS) using a website-based Analytical Hierarchy Process (AHP) method to determine the right location to build a communal WWTP. .
