Selection Guide

Determine Hydraulic Flow Rate: Calculate average daily flow and peak hourly flow in cubic meters per hour or day.

Characterize Influent Quality: Identify specific industrial contaminants, oil and grease content, or high initial COD loads requiring pre-treatment.

Verify Effluent Standards: Confirm local discharge or reuse regulations for surface water or landscape irrigation.

Evaluate Site Constraints: Check available footprint, indoor or outdoor placement, electrical availability, and containerized or buried installation requirements.

Select Sludge Disposal Method: Factor in sludge generation volume and local disposal protocols to size the sludge holding and dewatering modules.

FAQ

Q: What is the standard delivery lead time for a packaged sewage treatment plant?

A: Standard modular skid units and containerized systems require 25 to 35 working days from drawing approval. Large-capacity non-standard configurations require 45 to 60 days depending on steel plate fabrication schedules.

Q: Can the system operate reliably in sub-zero winter temperatures?

A: Yes. For outdoor installations in cold climates, internal tanks can be insulated with rockwool lagging, and electric heat tracing cables can be installed on exposed piping lines. Blowers and control panels are housed in climate-controlled enclosures.

Q: What is the typical operational lifespan of the submerged MBR membranes?

A: With routine chemical maintenance cleaning and adherence to recommended influent pretreatment limits, the MBR membrane modules deliver a service life of 5 to 8 years.

Q: Is professional site installation engineering support available?

A: Yes. Detailed English installation manuals, piping schematics, and electrical wiring diagrams are provided. On-site mechanical and electrical supervision by senior commissioning engineers can be arranged upon request.

Q: How is sludge handling managed within the automated package plant?

A: Excess biological sludge is periodically transferred from the aeration zone into an integrated sludge digestion hopper. The sludge is then conditioned for mechanical dewatering via a screw press or filter bag system.

Q: What utility requirements are needed on-site to operate the plant?

A: The site requires a stable 3-phase electrical supply matching the total connected motor load, a raw water supply source for chemical preparation and cleaning, and proper drainage infrastructure for treated effluent monitoring.
