Caustic Recovery System
Sanitech Engineers is one of the Top and Reliable caustic recovery systems manufacturers and providers meeting international regulatory standards.
CIP is very crucial in any process for which chemical cleaning is the method of choice. A Clean in place System ensures thorough internal cleaning without dismantling the equipment. Caustic is majorly used in CIP as it is cheap and easily available. The CIP cleaning solutions land up in high volumes, which adds to the load on the ETP process. Caustic soda recovery offers a 3-fold advantage:
- Saving caustic and water
- Saving acid, as caustic or high pH water cannot be sent to ETP directly. Thus, it needs to be neutralised, which generates salt
- Salts need to be removed before sending to ETP
Thus, a suitable caustic recovery system that can withstand high pH conditions can help in cost-effective caustic soda recovery and recycling, reducing waste generation, lowering operating costs, and promoting sustainable practices across various industrial processes including dairy, pharmaceuticals, biopharmaceuticals, petrochemicals, pulp and paper, textiles, and metal processing.
The CIP system or spent caustic usually contains impurities and contaminants, which are removed using a specialized membrane capable of withstanding pH up to 14.0.
A well-designed caustic recovery plant can integrate seamlessly into any cip system to improve efficiency and reduce environmental load.

FAQs
A caustic recovery system (CRS) is an industrial setup designed to reclaim and reuse spent caustic soda (NaOH) solutions that are used in cleaning, textile mercerization, or other process applications. Instead of discarding the caustic after it becomes diluted or contaminated, the CRS concentrates and purifies it through membrane filtration, evaporation, or other separation technologies, allowing industries to cut chemical costs, reduce wastewater load, and improve sustainability.
The caustic recovery process reclaims used caustic soda (NaOH) from industrial operations by filtering out impurities and concentrating the solution through membrane filtration or evaporation. The purified caustic is then reused in processes like textile mercerization, pharmaceutical cleaning, or food production. This reduces chemical costs, minimizes wastewater, and supports sustainable manufacturing.
The full form of CRP plant is Caustic Recovery Plant.
It is used to recover and recycle caustic soda (NaOH) from industrial processes, mainly in textiles, pharmaceuticals, and food industries, to reduce chemical consumption and environmental impact.
