Sodium Hypochlorite Production: Key Pain Points and On-Site Membrane Electrolysis Solutions

2024-12-19 17:59:47

Pain Point 1: Purchased finished bleach brings high cost, loss & unstable supply

Problems:
  • Outsourced 5%-15% sodium hypochlorite has expensive hazardous chemical transport fees; effective chlorine decays heavily during long-distance transit & storage, especially for Africa, power plant and municipal large-scale users.
  • Traditional electrolysis machines require ≥95% high-purity refined salt, with high salt & power consumption raising long-term operation expenditure.
  • Split discrete equipment needs complicated field assembly, long construction cycle, and insufficient local after-sales support for overseas projects.
Solution: BSHH Skid-mounted Membrane Electrolysis NaClO Generator
  • On-site integrated electrolysis directly produces adjustable 5%~15% high-concentration NaClO, fully eliminating finished bleach freight and concentration loss.
  • Optimized membrane electrolytic cell supports raw salt with NaCl purity ≥89%, cutting raw material procurement cost largely.
  • Plug-and-play skid design, customizable containerized mobile unit; local on-site technical service available for global clients including Africa.
Evidence & Operation Data:
  • Consumption standard: 1.9kg salt + 2.8kWh DC power per 1kg available chlorine
  • Max capacity: 30 tons daily 15% NaClO output for large African industrial clients
  • Full model range: chlorine output 0.5~30kg/h, covering small town disinfection to large chemical factories
  • Certifications: CE, ISO industrial safety certification

Pain Point 2: Different industries need various NaClO concentrations, double line investment waste

Problems:

Municipal water plants need 5% dilute disinfectant for tap water; daily chemical & pharmaceutical factories require 12%-15% high-concentration stock liquid. Buying two separate production lines causes redundant equipment investment and extra floor space occupation.

Solution: 5%-15% Stepless Adjustable Concentration Integrated System

Single unit freely switches NaClO concentration 5%–15% via intelligent PLC control. Besides sodium hypochlorite, the system co-produces chlorine, sodium hydroxide, hydrochloric acid and sodium chlorite for chlor-alkali and pharmaceutical intermediate manufacturing. Custom oversized tonnage units are available for chemical manufacturers.

Evidence & Operation Data:

Full specification series: chlorine output 0.5–30kg/h, matched 10% NaClO yield 5–300kg/h; floor area 15㎡~500㎡, unit weight 0.5–15 tons, lightweight skid for fast delivery and installation.

Pain Point 3: Conventional electrolysis equipment has safety hazards & frequent shutdown maintenance

Problems:
  • Ordinary electrolyzers have hydrogen leakage risk without isolation protection.
  • Manual brine dosing leads to unstable concentration; electrode scaling triggers frequent production stop.
  • No automatic monitoring system, high labor management cost for 24h running.
Solution: Fully Automatic Sealed Membrane Electrolysis Equipment
  • Closed electrolytic cell isolates hydrogen safely to avoid explosion risk.
  • Auto brine feeding, real-time temperature & current monitoring; auto periodic acid cleaning reduces scaling frequency.
  • Whole skid sealed anti-leak structure, compliant with global industrial safety standards.
Evidence & Operation Data:
  • Mass containerized units delivered & stable running overseas; long-term municipal sewage & thermal power plant operation cases.
  • Intelligent control cabinet supports 24h remote online monitoring & troubleshooting.
  • Complete interlock alarm system for abnormal pressure, temperature and liquid level.

Pain Point 4: Outsourced disinfectant faces supply chain instability & hazardous chemical approval limits

Problems:

Finished NaClO is classified as hazardous chemical with strict transport approval; market price fluctuates violently and supply shortage often occurs. Factories cannot independently control disinfectant quality standard.

Solution: Self-sufficient On-site Chlor-Alkali Production System

Only three basic raw materials required: industrial salt, tap water and electricity. Factories produce NaClO, caustic soda and chlorine for internal disinfection use, or pack finished disinfectants for resale to downstream distributors.

Evidence & Application Coverage:

Widely applied across full vertical industries: chlor-alkali chemical, daily chemical, thermal power circulating water, municipal water supply & sewage treatment, pharmaceutical intermediate manufacturing.
