Underground Septic Tank Sewage Treatment Biogas Wastewater Purification Tank
High-density polyethylene (HDPE) construction ensures superior durability, corrosion resistance, and leak-proof performance for long-term underground use. Precision rotational molding guarantees uniform wall thickness and structural integrity, capable of withstanding heavy soil pressure and extreme weather conditions. Integrated multi-chamber design optimizes anaerobic digestion, effectively separating solids, breaking down organic waste, and purifying wastewater for eco-friendly discharge. Includes built-in inlet/outlet pipes and access ports for easy maintenance and biogas collection, compatible with standard plumbing systems. Ideal for residential septic systems, rural biogas projects, agricultural wastewater treatment, and off-grid sanitation solutions.
