ECS compost aeration floors - the foundation of aerated compost system design
Inventive minds have come up with an amazing number of variations to channel air through a floor and into, or out of, a compost pile. Designs that have been based on sound engineering calculations and experience have generally worked. However, since all aeration floors are constrained by physics and Murphy, the floors that were less rigorously designed have not faired well. The characteristics ...

Effect of different forced aeration methods on Vertical temperature distribution and reaction rates During composting
The application of forced aeration, namely in the upflow (blowing) or downflow (suction) mode has been increasing in modern composting processes. These aeration modes often create a sharp temperature gradient in the composting mass. Examples of widely varying temperatures at different layers of controlled and non-controlled aerated piles have been reported frequently (Fernandes et al., 1994; ...

Application of household compost bin for diversion of organic wastes in small communities of Thailand
Natural ventilated and aerated composting units were developed for household, fresh market and restaurant wastes. Household wastes required 8-10 weeks of composting period. The final compost product contained N : P : K content higher than organic compost standard. In aerated unit, the composting period was 30-40 days. Economical analysis suggested Benefit-Cost (B/C) ratio and Economical Internal ...

Composting
Introduction Composting is a controlled biological process by which organic contaminants (e.g., PAHs) are converted by microorganisms (under aerobic and anaerobic conditions) to innocuous, stabilized byproducts. Typically, thermophilic conditions (54 to 65 °C) must be maintained to properly compost soil contaminated with hazardous organic contaminants. The increased temperatures result from heat ...

Chemical and physical properties of rice straw waste and hospital sewage sludge in turned windrow aeration system
In this paper, we present the main goal of optimum quality ratio of co-composting with rice straw waste and hospital sewage sludge. The experiments were designed by varying the initial C/N ratio and moisture content in the range of 25-45 and 30-70% w/w., respectively. The results clearly showed that the losses of Kjeldahl-N increased when the amounts of sludge in the mixtures were increased. The ...

Leaf composting in cold climates: a theoretical and an experimental evaluation
There are many factors influencing the process of composting organic waste. This paper provides an experimental and theoretical evaluation of the leaf composting process to elucidate the importance of these various factors during composting of leaves. The analysis is performed specifically for the environmental conditions encountered in cold climates. Theoretical models are developed to evaluate ...

Tulare Farms - Case Study
Tulare Lake Compost (TLC) is a state-of-the-art 175 acre composting facility located near Kettleman City in Kings County, California. At the facility, an eco-friendly process is used to combine agricultural and green waste from the Central Valley with biosolids from Los Angeles County to create an optimal mixture for composting. TLC employs the covered aerated static pile (ASP) composting ...

A cost-effective method for controlling compost air emissions
In October 2007, ECS began conducting trials at California State University Fresno (CSUF) to explore using the new patent pending AC Composter (ACC) covered aerated static pile system to manage dairy manure solids and comply with airquality standards. A two-zone portable pilot system was delivered by ECS and installed at the CSUF research dairy. This research is being conducted under a Phase I ...

How long does it take for organic fertilizer fermentation equipment to process compost
According to different raw materials, organic composting fermentation equipment can be divided into high temperature composting and ordinary composting. High temperature composting takes plant materials with high fiber content as the main raw materials, and generates a lot of heat through composting and fermentation under aerated conditions. The temperature of composting is very high (50-60 ...

Mariposa compost facility odor remediation update
Staring in the winter of 2006 the staff at the Mariposa Compost Facility worked quickly to make process changes to bring odor issues under control. Here is the latest chapter in their story. Odor (incident) Logs In January 2007 the Local Environmental Agency (LEA) provided "odor logs" to the county residents that were troubled by the compost facility's odors. The odor logs were collected ...
