Flocculation, disinfection, scale inhibition, pH adjustment and other processes in industrial water treatment all rely on chemical dosing systems. As the core container for chemical storage and solution preparation, the material and manufacturing process of the dosing tank directly determine the stable operation of the whole dosing system.
Many factories have encountered such on‑site problems:
⚠ Low‑quality ordinary dosing tanks will suffer corrosion, whitening and brittleness after long‑term storage of acid‑alkali chemicals, flocculants and disinfectants.
⚠ Slow leakage occurs at splicing joints and welds. Chemical drips cause material waste and site pollution.
⚠ The tank ages and cracks, requiring frequent replacement. Shutdown maintenance disrupts production schedules.
⚠ Chemical precipitation and uneven dissolving reduce dosing accuracy, leading to unstable effluent water quality.
These problems may seem to be “tank failures”, yet they are mostly caused by poor corrosion resistance of materials, spliced structures and unreasonable structural design.
✅ Chengda Industrial‑Grade PE Dosing Tanks, Specially Solve Corrosion, Leakage and Aging Problems
Chengda PE dosing tanks are made of food‑grade HDPE (High‑Density Polyethylene). Manufactured by blow‑molding / rotational‑molding one‑piece forming technology, the tank body has no seams, no splicing joints and no bonded areas. It eliminates the risk of joint leakage from the structural level.
Chemical‑resistant for various working conditions
HDPE features excellent chemical stability. It resists common acid‑alkali agents, flocculants (PAC / PAM), disinfectants (sodium hypochlorite), scale inhibitors and other commonly‑used water‑treatment chemicals. It will not get corroded or whitened easily under long‑time chemical storage.
Aging‑resistant & high toughness for long service life
Light‑weight yet tough, the tank features good shock‑resistance and impact‑resistance, with stable heat‑resistant and frost‑resistant performance. It hardly cracks or deforms in long‑term outdoor or workshop service, cutting frequent‑replacement costs and shutdown troubles.
Clear scale marks, even chemical dissolving & good compatibility
Clear volume scale lines are marked on outer tank walls for direct on‑site observation of liquid level and residual chemical volume. Reasonable structural design ensures even chemical dissolving and reduces chemical sediment accumulation. Pre‑reserved top ports support easy installation of mixers, metering pumps, level gauges and other accessories, to guarantee accurate dosing and stable process operation.
???? Multiple sizes in stock & custom‑made available for diverse application scenarios
Standard sizes of Chengda PE dosing tanks: 40L, 60L, 100L, 200L, 300L, 500L. Yellow and white colors are optional. Ample stock for fast delivery.
Custom services for special shapes, thickened walls and bracket‑mounted types are also available, to meet different site installation space and working‑condition requirements.
Wide application scenarios:
