The Challenge

Compliance failures stop production. Generic suppliers cannot protect you.

Bangladesh's regulatory environment for industrial effluent has tightened dramatically. Textile, pharmaceutical, tannery, and food processing factories face simultaneous pressure from government agencies and international buyers — with no margin for error.

DoE Enforcement

Bangladesh's Department of Environment conducts surprise inspections. Factories without certified ETP/STP systems face shutdown orders and production halts.

EU Buyer Audits

Export buyers require documented proof of compliant effluent discharge. A failed audit can terminate contracts worth millions overnight.

DIFE Inspections

The Department of Inspection for Factories and Establishments is increasing frequency of checks — non-compliant plants risk licence revocation.

Generic Suppliers

Off-the-shelf systems from catalogue suppliers arrive without site-specific engineering, regulatory documentation, or accountability for performance.

The Clearion Difference

Clearion engineers each system to your site's specific discharge requirements, provides full DoE documentation, and remains accountable through the plant's operational lifecycle — not just at the point of sale.

Our Systems

Five treatment technologies. One accountable engineering partner.

Every Clearion system is designed to your site's specific flow rates, inlet quality, and regulatory targets — not adapted from a generic catalogue.

ETP

Effluent Treatment Plant

Remove chemical, biological, and physical contaminants from industrial wastewater before safe discharge. Essential for textile, tannery, pharmaceutical, and food processing operations under DoE regulations.

Key Capabilities

  • Chemical coagulation & flocculation
  • Biological treatment stages
  • Sludge dewatering systems
  • DoE discharge compliance
WTP

Water Treatment Plant

Treat raw water from rivers, groundwater, or municipal sources into potable or process-grade water. Designed for factories, residential complexes, and commercial buildings.

  • Filtration & disinfection
  • Iron & manganese removal
  • Softening systems
  • BUET-standard designs
STP

Sewage Treatment Plant

Treat domestic and mixed sewage for residential towers, commercial complexes, hospitals, and hotels. Meets BNBC and DoE requirements for building permits and occupancy certification.

  • Biological activated sludge
  • Membrane bioreactor (MBR)
  • Compact packaged systems
  • BNBC & DoE certified
RO

Reverse Osmosis System

High-purity water for pharmaceutical GMP lines, food processing, textile dyeing, and boiler feed applications. Systems engineered for consistent TDS targets and WHO standards.

  • Multi-stage membrane arrays
  • Pre-treatment engineering
  • Remote monitoring capability
  • Pharmaceutical-grade options
ZLD

Zero Liquid Discharge

Recover and recycle up to 95–98% of process water — eliminating liquid waste entirely. Required by EU buyers and premium certification schemes; protects against future water scarcity.

  • Evaporation & crystallisation
  • High-recovery RO integration
  • Brine management systems
  • EU supply-chain compliant

Why Clearion

Engineering-first. Not equipment-first.

Most suppliers sell equipment. Clearion sells certainty — the engineered confidence that your plant will pass inspection, satisfy buyers, and stay operational.

Site-specific engineering

Every system is designed from a site survey — not selected from a catalogue. We match treatment capacity to your actual flow rates, inlet quality, and regulatory discharge limits.

DoE compliance documentation

We prepare and submit the complete regulatory package — design drawings, test reports, and operational manuals — that DoE inspectors and EU buyer auditors require.

Lifecycle maintenance contracts

Our maintenance teams perform scheduled servicing, reagent restocking, membrane replacement, and emergency response — keeping your system performing and your licence valid.

Multi-industry expertise

From textile dyeing effluent with complex dye chemistry to pharmaceutical-grade RO for GMP compliance — our engineers have hands-on experience across Bangladesh's major industrial sectors.
