Frequently Asked Questions (FAQ)
Q1: What is the typical COD removal efficiency of this system?
A: Depending on the influent COD concentration and selected process configuration, the system can achieve 90%–98% removal. We design each unit to meet your target effluent standard.
Q2: Does the 1-year warranty cover all parts and labor?
A: The warranty covers manufacturing defects in parts and workmanship. Normal wear items (e.g., seals, filters) are excluded unless they fail due to defects. On-site labor during the warranty period is included for repairs if needed.
Q3: How long does the on-site commissioning training take?
A: Typically 3–7 days depending on system complexity and operator experience. Our engineers will guide your team through startup, operation, maintenance, and safety protocols.
Q4: What industries are suitable for this high COD system?
A: It is ideal for food & beverage, pharmaceutical, chemical, petrochemical, textile, pulp & paper, and landfill leachate treatment – any industry with high-strength organic wastewater.
Q5: Can the system be customized for different capacities or site constraints?
A: Absolutely. We offer modular designs from 10 m³/day to over 500 m³/day. Layout can be adapted to limited footprints, and pretreatment (equalization, screening) can be integrated as needed.
Q6: What is the typical delivery time?
A: For a standard system (after final design approval), lead time is about 30–60 days depending on capacity and complexity. Rush orders may be possible with prior arrangement.
Q7: Do you provide after-sales technical support?
A: Yes, we provide remote technical support via phone/email/video for the lifetime of the equipment. Spare parts are readily available from our Qingdao warehouse.
Q8: What are the power requirements and do you support different voltage?
A: Standard configuration is 380V/220V 50Hz 3-phase, but we can customize for 60Hz, 415V, 460V, etc., according to your local grid.
