MCR Treatment for Chemical Plant Cooling Blowdown

An integrated MCR softening and membrane-treatment route for high-hardness circulating cooling blowdown at a chemical enterprise.

Project statusIndustrial operation
Treatment capacityApprox. 50 t/h
Feed challengeHigh hardness, ammonia and COD
ApplicationReuse and ZLD pretreatment
Project Background

A compact softening route for a constrained industrial site

The supplied project document describes cooling blowdown with high hardness and silica, together with elevated ammonia nitrogen and COD. The site required a high system recovery while limiting footprint, so the project adopted an integrated MCR-based pretreatment route before reverse osmosis.

Process route

  • Two-stage chemical reaction and conditioning
  • MCR membrane chemical reactor for solid-liquid separation
  • Cation bed for residual hardness removal
  • Feed RO followed by concentrate RO
  • Concentrate directed to downstream salt separation or evaporation
Documented Project Information

Results reported in the supplied technical file

Hardness

The document reports reduction from approximately 1,500 mg/L as CaCO3 to below 30 mg/L.

Silica

The document reports reduction from approximately 65 mg/L to below 10 mg/L.

System recovery

The complete system is reported to achieve more than 90% water recovery.
