Opis:: In the last five decades, the variation for increase in population and decrease in available clean water is noticeable. To meet with growing water requirements, along with the wastewater from municipal sewage treatment plants, it is critical to consider the reuse of industrial wastewater wherever possible. In the Indian context, this has already been started in some of the big industries, especially in metro cities and it must be implemented at all level possible industries. Ultrafiltration (UF), reverse-osmosis (RO) and membrane bioreactors (MBR) will be integral parts of this. Waste water reuse is not only a necessity, it also provides several eco-friendly benefits.

Opis:: This paper describes the methodology and test results of diesel particulate filter (DPF) functional testing performed on non-road compression ignition engine application installed on test bed. The scope of work included testing of various DPF regeneration strategies, backpressure and balance point tests and emission performance evaluation during a legislative test cycle. The aim of this study was to observe and investigate the influence of raw exhaust gas parameters on DPF functionality in terms of filtration efficiency, soot loading, type and duration of the regeneration and emission performance. Under investigation was the capability of soot burning rate and fuel penalty. The DPF sample under test was part of the complete exhaust aftertreatment system (ATS) which consisted of: a diesel oxidation catalyst (DOC), a DPF and a selective catalytic reduction system (SCR) with urea dosing and ammonia slip catalyst (ASC). Testing was carried out on a heavy-duty diesel engine installed on a test stand with a dynamic dynamometer and equipped with an emission bench. The test program allowed to assess the engine matching to exhaust aftertreatment system with regard to emissions compliance, in-service operation and necessary engine control unit (ECU) calibration works. The results show the influence of the DPF regeneration strategy on its duration and on the soot mass burn rate. Passive DPF regeneration was a favorable mode of DPF cleaning, due to lack of fuel penalty and lower aging impact on the entire ATS. Optimization of soot flow rate, exhaust gas temperature and the chemistry of the DOC/DPF was further recommended to ensure the long-term durability of the entire system.
