Biogas slurry is a potential sustainable substitute for chemical fertilizers and soil amendment to restore organic matter depletion structural deterioration. The effects of substituting biogas fertilizer on lime concretion in the North China Plain were investigated. A field experiment examined consequences applying different proportions (0, 25, 50, 75 100%) slurry, while maintaining same total ...

This study explored the possibility of using upgraded coal and coke from Indonesian lignite in ironmaking process, specifically pulverized Injection (hereafter, “PCI”) carbon composite pellets material (sintering binder material). The found that (1) injection into blast furnace will have same effect as lime - heavy oil slurry furnace, combined infusion highly volatile matter low ash coal, flash...

The use of zeolitic material synthesized from coal fly ash for the immobilization of pollutants in contaminated soils was investigated in experimental plots in the Guadiamar Valley (SW Spain). This area was affected by a pyrite slurry spill in April 1998. Although reclamation activities were completed in a few months, residual pyrite slurry mixed with soil accounted for relatively high leachabl...

Controlled pH, liquid hot water pretreatment of corn stover has been optimized for enzyme digestibility with respect to processing temperature and time. This processing technology does not require the addition of chemicals such as sulfuric acid, lime, or ammonia that add cost to the process because these chemicals must be neutralized or recovered in addition to the significant expense of the ch...

The use of lime to reduce or eliminate pathogen content is a cost-effective treatment currently employed in many Class B biosolids production plants in the United States. A bench scale model of lime stabilization was designed to evaluate the survival of adenovirus type 5, rotavirus Wa, and the male specific bacteriophage, MS2, in various matrices. Each virus was initially evaluated independentl...

Surface quality including surface roughness and edge chipping is a key process measure in micro ultrasonic machining (Micro-USM) as an efficient process for micromachining of hard and brittle materials. Process parameters such as ultrasonic vibration amplitude, static load, type of tool material, type and size of abrasive particles and slurry concentration can influence the surface quality. How...

Seed germination is the most important aspect for raising nursery successful seedling production of acid lime. The present study was carried out to explore effect different seed soaking treatment with growing media on and survivability lime (Citrus aurantifolia Swingle) under net house condition. experiments were laid as a Completely Randomized Design Factorial concept comprising twenty four co...
