Bolong has long been dedicated to helping clients achieve clean, green, and effective farming management by offering integrated solutions for odor and manure control in large-scale livestock farms.
These days, a lot of big pig farms frequently deal with issues like manure buildup, illegal wastewater discharge, and odor nuisances that affect nearby residents. In light of this, Bolong created a successful environmental treatment demonstration project for a 30,000-pig farm in Vietnam.
Bolong’s specially designed pig manure fermentation tank system has helped the farm overcome its problems with manure treatment and odor. This system reduces environmental pressures on the operation by processing manure, wastewater, and exhaust gases in a safe, resource-efficient, and intelligent manner.
Before adopting the Bolong pig manure fermentation tank system, the farm primarily relied on piling or rudimentary composting to manage manure.
This approach not only required lengthy fermentation periods and produced intense odors but also caused severe pollution. High concentrations of organic matter and ammonia nitrogen in wastewater made compliance difficult, with odors spreading to nearby residential areas during hot summers.
The client urgently required a manure treatment system capable of efficient fermentation, odor removal, pollution reduction, energy conservation, and environmental protection. Bolong pig manure fermentation tank system perfectly met these requirements, complying with environmental regulations while enabling the circular reuse of farming resources.
Considering the client’s actual farm conditions, the Bolong team engineered an integrated pig manure fermentation tank system covering solid-liquid separation, fermentation, wastewater purification, and exhaust deodorization–achieving efficient, unified treatment of solid, liquid, and gaseous waste.
Pig manure first enters the solid-liquid separation equipment to separate solids from wastewater. The solid fraction is directly fed into the manure fermentation tank for high-temperature processing, while the liquid flows into oxidation ponds for sedimentation and aeration.
This step effectively reduces the load on subsequent systems and enhances overall fermentation efficiency.
Within the Bolong fermentation tank, manure undergoes temperature- and oxygen-controlled processing, achieving full maturation in just 7 days.
The entire process achieves significant high-temperature sterilization and deodorization, efficiently converting manure into high-value organic fertilizer while markedly improving the farm environment.
Separated wastewater enters oxidation ponds for multi-stage sedimentation, aeration, and flocculation purification.
Settled sludge is mixed proportionally with manure fertilizer and reintroduced into the fermentation tank for secondary fermentation. Treated water meeting standards is recycled, achieving true “zero discharge.”
Since implementing the Bolong Pig Manure Fermentation Tank System, clients report significant outcomes:
Odor emissions reduced by over 80%;
Wastewater discharge meets environmental standards and is recycled;
Manure is successfully converted into high-quality organic fertilizer, achieving”waste-to-resource” transformation;
Intelligent system operation reduces labor and energy costs.
Following system upgrades, the farm’s overall operations have stabilized with markedly improved environmental metrics. This marks a genuine shift from “pollution control” to “profit generation” ,establishing a replicable green model for modern livestock farming.
Bolong has years of engineering and practical experience in waste treatment and fermentation tank manufacturing.
Its independently created pig manure fermentation tank system, which is extensively used in large and medium-sized farms throughout Asia and Africa, combines multi-stage deodorization technology, intelligent control, and energy-efficient design.
Bolong empowers customers to accomplish effective environmental transformation by offering not only hardware equipment but also full-chain support, from solution planning and on-site installation to technical training and after-sales service.
Your farm can attain triple value by selecting the Bolong Pig Manure Fermentation Tank System: long-term profitability, environmental compliance, and energy savings and efficiency gains.
