Suatu industri bioetanol menghasilkan limbah dalam proses produksinya, salah satunya adalah limbah padat berupa activated sludge. Keberadaan dari limbah padat ini semakin lama semakin menumpuk sehingga perlu dilakukan pengolahan menjadi sesuatu yang lebih... see more

Hasil samping instalasi pengolahan air limbah di industri bioetanol menghasilkan limbah padat berupa activated sludge. Limbah ini dapat menimbulkan masalah apabila tidak ditangani dengan benar. Diantaranya adalah menurunkan kandungan hara dalam tanah dan ... see more

In this work, an activated sludge lab-scale reactor used for nitrification was monitored by specific activity kinetic assays. The nitrification biomass activity was carried out by respirometric methods in order to characterize the inoculum and the reactor... see more

Activated sludge system is the most important stage in municipal wastewater treatment process. It is a biological operation used for treating sewage by means of microorganism. One type of activated sludge systems is the oxidation ditch. In this work, mode... see more

Tofu wastewater contained high organic matters and relatively fluctuated in Chemical Oxygen Demand (COD) of about 5.000 to 8.000 mg/L. A Combination of Anaerobic Baffled Reactor (ABR) and Activated Sludge System was very useful to reduce organic matter an... see more

This paper investigates the performance of a new predictive control approach used to improve the energy efficiency and effluent quality of a conventional Wastewater Treatment Plant (WWTP). A modified variant of the well-known Generalized Predictive Contro... see more

Conclusions. Results show that excess sludge biomass can be used to obtain magnetic sorbent, which can be made without the use of extra magnetization with artificial magnetic nanoparticles. This allows extracting sorbent using methods of high gradient mag... see more

In the work presented in this paper, data-driven control is used to tune an Internal Model Control. Despite the fact that it may be contradictory to apply a model-free method to a model-based controller, this methodology has been successfully applied to a... see more

The purpose of the current study is to enhance filterability of activated sludge by applying controlled DC electric field via perforated aluminum electrodes, meantime to provide an ineffective electric current on bacterial life. The studies were conducted... see more
