Qingdao Conqinphi Environmental Technology Group Co., Ltd. introduces its advanced ZLD Water Treatment System specifically designed for the pharmaceutical industry. Manufactured with high-quality 304 stainless steel and a sanitary design, this system ensures zero liquid discharge while meeting strict hygiene and purity standards required in pharmaceutical production. As a trusted manufacturer with over 9 years of experience and a factory spanning 10,000-30,000 square meters, we bring reliable, efficient, and compliant water treatment solutions to global pharmaceutical facilities.
Our ZLD system is engineered to recover up to 98% of wastewater, converting it into high-purity water for reuse while leaving minimal solid waste. The 304 stainless steel construction resists corrosion and ensures long service life, while the sanitary design eliminates crevices and dead legs, preventing bacterial growth and cross-contamination. This makes it an ideal choice for pharmaceutical plants producing APIs, injectables, oral liquids, and cleaning processes.
Key Features & Technical Specifications
- 304 Stainless Steel Construction – All wetted parts made of 304 SS, with optional electropolishing for enhanced smoothness.
- Sanitary Design – Tri-clamp connections, 3A compliant, easy to clean and sterilize (CIP/SIP compatible).
- Zero Liquid Discharge (ZLD) – Combines reverse osmosis (RO), evaporation, and crystallization to achieve near-zero wastewater discharge.
- High Recovery Rate – Water recovery rate >95% (typical), reducing freshwater consumption and operational costs.
- PLC & HMI Control – Fully automated system with touch screen interface, remote monitoring capability, and data logging.
- Low Energy Consumption – Energy-efficient pumps and heat recovery systems minimize power usage.
- Compact Footprint – Skid-mounted design saves floor space and simplifies installation.
- Compliance – Designed to meet GMP, USP, and EP standards for pharmaceutical water systems.

Frequently Asked Questions (FAQ)
- What is a ZLD water treatment system and why is it used in pharmaceuticals? ZLD stands for Zero Liquid Discharge. It is a treatment process that recovers nearly all water from wastewater, leaving only dry solids. In pharmaceuticals, it ensures compliance with strict environmental regulations and provides high-purity water for critical processes.
- Is the system made entirely of 304 stainless steel? Yes, all wetted parts are constructed from 304 stainless steel, which is resistant to corrosion and easy to clean. Optional 304L or 316L stainless steel is available upon request for applications with higher chloride content.
- Can the system be integrated with existing CIP/SIP systems? Absolutely. The sanitary design includes tri-clamp connections and smooth surfaces, making it compatible with standard Clean-in-Place and Sterilize-in-Place processes.
- What is the typical water recovery rate? Our ZLD system achieves a recovery rate of greater than 95%, meaning less than 5% of the feed water is lost as solid waste or brine.
- Does the system require specialized operators? No. The PLC-controlled automation with HMI touchscreen makes operation intuitive. Our team provides training for your operators during commissioning.
- How long does installation take? Installation time depends on system size and site conditions. Typically, a skid-mounted system can be installed and commissioned within 2–4 weeks.
- What certifications does your company hold? We are certified under ISO9001, HACCP, SA8000, and other management systems. Our products are designed to meet GMP and USP standards for pharmaceutical water.
- Can you customize the system for a specific feed water quality? Yes. We analyze the feed water composition and design the system accordingly, including pre-treatment, RO, evaporation, and crystallization stages tailored to your needs.
