NCS membrane composting technology three elements: air permeability is the foundation, moisture is the key, temperature is the guarantee


NCS membrane composting technology is based on polymer membrane selection, and intelligent control system, is an organic combination of static composting and reactor composting, can truly achieve efficient, environmental protection, safety, low-cost harmless treatment and fertilizer utilization of agricultural waste.The technology is simple and flexible, similar to static composting, and provides similar conditions to reactor, but the composting effect is better than static composting, odor control effect is better than reactor, so it is a process with very high cost performance.When NCS membrane compost is used to make organic compost, after it enters the fermentation process, the water content, air permeability and temperature of compost become the key factors for the success of fermentation.The regulation of permeability is that in the process of basic composting, the air permeability, that is, the oxygen supply of materials, is reflected by temperature and odor.Abnormal changes in compost temperature or odor, odor, it shows that there is a problem with air permeability.NCS membrane compost mainly controls air permeability through membrane material and air supply.The membrane material is divided into three layers, in which the outer and inner layers are two layers of polyester fiber breathable membrane material, and the middle layer is e-PTFE molecular membrane membrane material, which has a micromolecular filtration micropore structure, odor, dust, bacteria and other can not pass through, and the outside rain and snow can not enter.It can realize the relative sealing of fermentation reactor body, reduce the generation of odor, and effectively eliminate odor overflow, the effect is up to 90%.The intelligent control system of NCS membrane composting system, with multiple probes to detect the temperature, humidity and oxygen of the heap, combined with the composting process to automatically control the high pressure oxygen supply intensity, the Internet of Things control system to control the indirect air supply system, which can achieve full automation.Moisture regulation is the primary condition for composting to keep proper moisture content in the key composting process.Since most microorganisms lack water retention mechanisms, they are extremely sensitive to water.When the water content was between 35% and 40%, the degradation rate of compost microorganisms decreased significantly, but when the water content was below 30%, the degradation process stopped completely.Too little water, limited microbial activity, affect composting speed;Too much water will block the gap between compost materials, affect its permeability, easy to form anaerobic state, and produce odor, nutrient loss, composting speed is also slow.Temperature regulation is a key indicator to ensure that temperature is compost!Will the system heat up?How much heat?How long can the heat last?How does the ratio of raw materials affect temperature?All these are important points to pay attention to in the membrane composting process.The requirements for temperature change of compost can be summarized as follows: the temperature in the early stage rises rapidly and steadily;Medium high temperature maintenance;The temperature drops slowly in the later period.The length of high temperature maintenance time reflects the quality of formula adjustment and pre-treatment of raw materials, and it is best to maintain more than 5~10 days.In many cold regions, NCS compost can still ferment normally.Therefore, water, gas and temperature are usually called the three elements of composting.The three influence and relate to each other.
