Liquid Orgaic Fertilizer Manufacturing Process

If you are looking for a dehydrator for an organic fertilizer production plant, you can definitely consider our company. We have rich production experience in the production of fertilizer dewatering equipment. Among them, our inclined solid-liquid separator is a small machine for handling organic waste with high water content (>85%). This machine covers only 3-6㎡. Obviously, it is suitable for material pretreatment in small organic liquid fertilizer plants. In general, the minimum scale SXTSX-800 can process 20-25m³/h of cow manure, pig manure or sludge; 10-15m³/h of chicken manure or traditional Chinese medicine residues; 15-20m³/h of distillers’ grains, etc. In addition, our factory can customize the specifications of the filter screen according to the material requirements of customers. Secondly, the whole machine is made of 304 stainless steel material, which meets the needs of liquid and viscous feces treatment.

Recently, our company has developed a new type of solid-liquid separation equipment that utilizes screw extrusion dehydration. It is suitable for high and low concentration sludge in industries such as municipal sewage, food, chemical, metallurgy, mine processing, papermaking, printing and dyeing, pharmaceuticals, etc. If you want to process low concentration (2000mg/L) sludge for liquid organic fertilizer manufacturing, there is no need to build a storage tank, which reduces construction costs. Moreover, this dewatering device has compact structure, including an electrical control cabinet, a metering tank, a flocculation mixing tank, and a main body. Also, it has small footprint, light weight, and is easy to transport and maintain. The speed of the spiral shaft is about 2-3r/min, with low electrical consumption. Besides, the body is almost entirely made of stainless steel material, which make the service life more than 2 times of similar products. In order to achieve 24-hour continuous unmanned operation, we choose high-performance motors with a protection level of IP54 and an insulation level of F.

Furthermore, our company has promoted a new and efficient liquid-liquid extraction and separation equipment. This device utilizes the centrifugal force generated by high-speed rotation to efficiently separate liquid components with different densities. In the liquid organic fertilizer production process, centrifugal extraction machine can effectively separate organic substances and impurities, concentrate useful components, remove excess solvents and water, and meet the preparation requirements of high concentration liquid organic fertilizers. In addition, it is suitable for the extraction of lactic acid fermentation solution and industrial wastewater treatment. Compared with traditional separation methods, it can complete the separation and purification process in a shorter time, reducing production costs. Typically, the selectable materials for equipment include 304, 316L stainless steel, composite materials, or fluorine materials. Also, the wastewater treatment capacity is 15-150m³/h, the power is 4-11kw, and the weight is 860-2500kg.

The construction of sedimentation tank of organic liquid fertilizers production includes anaerobic fermentation, aggregate, and storage tanks. You can design its size and configuration according to specific process requirements and production scale. Firstly, the anaerobic fermentation process requires the sealing and structural strength. So it is necessary to use high-quality cement materials to ensure no leakage or cracks of sedimentation tank. Secondly, the aggregate pool can collect 10% organic sediments. Also, this part requires a drainage and sedimentation system to ensure sufficient separation of solids and liquids. Finally, the storage pool can temporarily store the liquid, ready for the next step of liquid fertilizer production.

In order to better serve our customers, we can provide detailed construction drawings for free. This will include information on the overall layout, specific dimensions, material selection, and other aspects of the sedimentation tank. If necessary, we can also dispatch a professional team to conduct on-site inspections and measurements to ensure that the design and construction of the sedimentation tank fully meet the site conditions and specific needs of the clients.

Furthermore, you need to install such a duplex filter at every step of liquid organic fertilizer production to improve the quality of the finished liquid fertilizer. Moreover, you can set up a two-stage filtration system. With the first filtration unit removing medium-sized particles and impurities, the second unit eliminates finer substances. Additionally, it has CIP cleaning function for keep filter performance.

In addition, we may customize filter materials based on customer requirements – carbon steel, 304, 316 stainless steel. Also, we have a mirror finish or matte finish for the surface of this filtering machine. The screen hole diameter of double filter is about 60-400 mesh. Besides, its working pressure is less than 0.2MPa. And the filtering capacity is 5-10t/h.

In fact, the filtered organic liquid fertilizer may require further post-treatment, such as UV disinfection or microfiltration. So, we will basically equip the dual filter with a UV sterilizer at the same time. Both the inside and outside of the main body are made of 304 or 316 stainless steel, and we do polishing to improve ultraviolet radiation. Also, it suitable for various water treatment projects, including sewage treatment engineering, drinking water disinfection, and more. Its purpose is to kill bacteria, viruses, yeast, mold, algae and degrade chloride in water. The ultraviolet sterilization band is mainly between 200-300nm, with the strongest sterilization ability at a wavelength of 253.7 nm. Thus, you can adjust it through the control cabinet. In general, we guarantee our product quality, and we use PHILIPS brand UV lamp tubes with an effective service life of up to 12,000 hours. Also, we offer a 10-year guarantee on the stainless steel shell and a 1-year guarantee on other accessories.

Certainly, water treatment machine is always a little expensive. For low budget and small liquid organic fertilizer factories, you can buy this to produce 1-50m³/h pure water. In particular, this equipment uses high-end reverse osmosis membranes, with a desalination rate of up to 98-99%. Simultaneously, it is equipped with activated carbon or quartz sand filters, effectively removing soluble salts, TOC, and SiO2. Moreover, the inlet water pressure is about 0.2-0.5MPa and the single equipment’s power of 2.25kw. Moreover, the reverse osmosis recovery rate is 60-75% for primary RO water system and 80-85% for secondary part. Also, the source water hardness is about <10mmol/L, and the outlet water hardness is ≤0.03mmol/L.

In addition, for large-scale organic liquid fertilizer manufacturers, we recommend using ultrafiltration membrane components. Because it can form an integrated water treatment system with the capacity of 10-100t/h. And if you have sufficient funds, it can reach 200 t/h of water treatment efficiency. Moreover, this device is made of polyvinylidene fluoride (PVDF), which has excellent chemical stability and mechanical strength. Besides, the membrane pore size is 0.03 μ m-1nm, which can remove 100% impurities such as suspended particles, colloids, chromaticity, turbidity, organic chemicals, bacteria, and Escherichia coli with the size greater than 2um. Also, the shell material of this large commercial ultrafiltration system is UPVC, which has brilliant corrosion resistance. Hence, you can use our liquid fertilizer equipment to treat the organic waste liquid with a ≤0.2 NTU turbidity and ≤3.0 SDI. Furthermore, we ensure that the filtered liquid fertilizer is clear and pure. And the service life of the components is up to 5 years.

Corrosion resistant pumps and flow meters are essential auxiliary equipment in the production process of organic liquid fertilizers. For one thing, the water pumps can transport corrosive organic fertilizer liquids. Usually, they are made of anti-corrosive materials such as stainless steel, alloys, or special plastics. Thus, it can effectively prevent the corrosion of the pump body by acidic and alkaline liquids. So it can still maintain good working conditions, extending the lifespan of the entire organic liquid fertilizer production line.

For another thing, flow meters commonly include electromagnetic flowmeters, ultrasonic flowmeters, and turbine flowmeters. Typically, they have functions of real-time monitoring and measurement of the flow rate of liquid fertilizers through automatic control systems. Then, you can achieve precise adjustment during the liquid fertilizer production process. Its design requires high precision and corrosion resistance, improving production efficiency and product quality.
