Airflow in Passively Aerated Compost
Passive aeration systems are more economical than active aeration systems and deliver similar performance, but mathematical descriptions of the process are inadequate for use in design or optimization. Therefore, a practical analytical model of airflow development in passively aerated compost was developed. The model relates the physical characteristics and temperature of the compost with the p...
متن کاملStandard Bread
Sir,?I was glad to see the letter on this subject from " B. A. C." in your last issue, together with your editorial approval of it. Can nothing be done to indfi.ee bakers to give us really palatable and nutritious bread ? No doubt they will say, as you do, that their customers love to have ill-baked, tasteless bread. But once upon a time j)eople were content with smelly omnibuses carpeted with ...
متن کاملCharacterization of Odorant Compounds from Mechanical Aerated Pile Composting and Static Aerated Pile Composting.
We studied airborne contaminants (airborne particulates and odorous compounds) emitted from compost facilities in South Korea. There are primarily two different types of composting systems operating in Korean farms, namely mechanical aerated pile composting (MAPC) and aerated static pile composting (SAPC). In this study, we analyzed various particulate matters (PM10, PM7, PM2.5, PM1, and total ...
متن کاملTreatment of landfill leachate with aerated and non-aerated submerged biofilters.
A submerged biological filter packed with clayey schists from brick industrial waste as support material was used to treat landfill leachate. The pilot-scale plant consisted of two separated reactors, running in aerated and non-aerated conditions respectively. The leachate was taken from a landfill in Granada (southeast Spain) and was considered as partially stabilized with average chemical oxy...
متن کاملOxygen Transfer in a Biological Aerated Filter
The City of San Diego (City) operates the Point Loma Wastewater Treatment Plant (PLWTP) which can normally treat up to 240 million gallons per day (MGD) of chemically enhanced primary treated (CEPT) effluent for ocean disposal. The City wanted to understand the performance capabilities of Biological Aerated Filters (BAFs) in treating CEPT effluent to secondary standards. To this end, the City c...
