pH Neutralizer (NaOH 99%)

Description

1. Product Overview

The pH Neutralizer (NaOH 99%) is a high-purity, white caustic soda granular formulation engineered for large-scale industrial pH adjustment, effluent treatment, and chemical intermediate processing. Its primary industrial use spans wastewater management, pulp & paper production, textile processing, and chemical manufacturing, where precise alkalinity control is mission-critical. The key value proposition is delivering consistent, verifiable 99% purity that minimizes scaling, reduces downstream contamination, and lowers total chemical consumption per batch. In a market increasingly driven by regulatory pressure and operational efficiency, this product serves as a strategic enabler for compliant, cost-effective pH neutralization at scale.

2. Key Specifications & Technical Characteristics

• Chemical composition: Sodium hydroxide (NaOH) – minimum 99.0% by weight

• Purity grade: Industrial technical grade, compliant with ISO 9001:2021 production standards

  • White, flaked or pearl solid form (spherical granules)

  • Free-flowing, low dust generation

  • Bulk density: 0.95 – 1.05 g/cm³

  • Particle size: 0.5 – 1.5 mm (pearl) / 1.0 – 3.0 mm (flake)

• Impurity limits (max):

  • Na₂CO₃: ≤0.5%

  • NaCl: ≤0.05%

  • Fe₂O₃: ≤0.003%

• Packaging options:

  • 25 kg multilayer laminated HDPE/paper bags

  • 500 kg and 1,000 kg FIBC (big bags)

  • Bulk pneumatic tanker delivery (up to 25 MT per load)

• Shelf life: 24 months in original unopened packaging, stored below 40°C in dry, well-ventilated conditions

3. Core Industrial Applications

• Primary industries: Municipal and industrial wastewater treatment, pulp & paper, textile wet processing, chemical synthesis, metal finishing, and oil & gas produced water treatment.

• Operational use cases:

  • Neutralization of acidic process effluents (H₂SO₄, HCl, HNO₃ streams) before biological treatment

  • pH boosting in pulp bleaching sequences (extraction stage)

  • Scouring and mercerization in textile mills

  • Catalyst pH control in petrochemical alkylation units

• Performance advantage over alternatives:

  • Compared to lower-purity (95–97%) NaOH, 99% grade reduces scaling in dosing pumps and heat exchangers by up to 40%, lowering maintenance downtime.

  • Versus lime (Ca(OH)₂), it delivers rapid, sludge-free neutralization with lower capital infrastructure costs (no sludge dewatering).

  • Higher concentration per kilogram reduces storage footprint and freight cost per neutralization equivalent.

4. Competitive Advantages

• Quality consistency: Batch-to-batch coefficient of variation <2% for purity and heavy metals — supported by ISO 17025-accredited lab reports shipped with every lot.

• Supply reliability: Dual-sourced chlor-alkali production from natural gas and renewable energy–backed plants in Asia and Middle East, with 99.5% on-time-in-full performance over 36 months.

• Logistics capability: Dedicated hazmat-certified supply chain (Class 8 corrosive solid) with containerized, break-bulk, and pneumatic options; port-to-door tracking via digital visibility platform.

• Price competitiveness: Direct ex-works and CIF pricing models with quarterly index-linked adjustments — no opaque distributor markups.

• Sustainability & compliance: Zero added mercury or cadmium; meets EU REACH, UK CLP, and US TSCA. Residual sodium carbonate content below 0.5% reduces CO₂ release during dissolution.

• Technical support: Free titration-based dosage optimization template + 24-hour SDS, CoA, and stability documentation access via supplier portal.
