From a theoretical investigation of the continuity of wastewater organic (COD) and N compounds along the links connecting the primary settling tank (PST), fully aerobic or N removal activated sludge (AS) treating raw and settled wastewater and aerobic digestion unit operations, it was found that the PS characteristics, viz. the biodegradable and unbiodegradable soluble and particulate COD and N...

iran is the center of origin as well as variation for pomegranate (punica granatum l.). also, iran is one of the most important countries in the world in terms of pomegranate culture and production. monitoring morphological and physiological changes which occur during fruit growth and development is an important determining in orchard management decisions. the aim of the present research was to...

To better understand how airways produce thick airway mucus, nonvolatile solids were measured in liquid secreted by bronchi from normal pig, cystic fibrosis (CF) human, and non-CF human lungs. Bronchi were exposed to various secretagogues and anion secretion inhibitors to induce a range of liquid volume secretion rates. In all three groups, the relationship of solids concentration (percent nonv...

Major losses of fresh tomatoes happen during post-harvest storage due to prompt senescence and diseases. The aim the research was evaluate effects different spectra LED lights on preservation ascorbic acid, lycopene, total soluble solids, weight size tomato fruits, as well determine optimal exposure time distance irradiation extension shelf-life. Therefore, experiments were carried out in a cli...

Oat (Avena sativa) is a cereal rich in fiber and nutrients necessary for good health. This study was conducted to develop oat flakes incorporated yogurt. flake concentrations were used at 2.5, 3.75, 5 g of oats per 100 ml milk. The selected concentration from sensory evaluation compared with commercial yogurt consumer preference proximate analysis. shelf life the sample determined by measuring ...

This study is to offer a 1st insight in the use of membrane process for the purification and concentration of Vietnamese fruit juices: cashew apple (Anacardium occidentale Line.), dragon fruit (Cactus hémiépiphytes), pineapple (Ananas comosus), pomelo (Citrus grandis L.), and gac aril oil (Momordica cochinchinensis Spreng.). On a laboratory scale, the effect of different operating parameters su...

A 69-day experimental study was conducted to investigate the treatment process of municipal wastewater using submerged membrane bioreactor technology. The results show that the average removal rate of COD and BOD5 were over 90%. The removal rate of NH3-N was 99% and the concentration of effluent NH3-N was below 0.5mg/L; because of the high DO value in the denitration sect, the denitrobacteria w...

Stormwater suspended solids typically are quantified using one of two methods: aliquot/subsample analysis (total suspended solids [TSS]) or whole-sample analysis (suspended solids concentration [SSC]). Interproject comparisons are difficult because of inconsistencies in the methods and in their application. To address this concern, the suspended solids content has been measured using both metho...

The rational use of nutrients is of fundamental importance for obtaining high productivity of high nutritional quality. This work was developed with the aim of evaluating the quality of pepper fruit grown under different fertigation managements and different levels of nitrogen and potassium. The experimental design was of randomised blocks in a 3 x 6 factorial scheme with four replications. The...
