Selection Guide

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

Analyze Influent Composition: Identify specific contaminants, oil levels, or high toxic loads requiring specialized pre-treatment before the package unit.

Verify Discharge Standards: Confirm local environmental regulations for direct water body discharge or landscape reuse.

Evaluate Site Space and Logistics: Check crane access, truck transport size limits, indoor or outdoor placement, and whether an above-ground skid or buried package tank is needed.

Determine Sludge Handling Protocol: Factor in sludge generation rate to size the internal digestion hopper and external disposal logistics.

Manufacturing and Quality Control

FAQ

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

A: Standard modular skid units require 25 to 35 working days from drawing approval. Large-capacity multi-module systems require 45 to 60 days depending on steel fabrication schedules.

Q: Can the package plant operate in freezing winter conditions?

A: Yes. For outdoor cold-climate installations, external tanks can be fitted with rockwool insulation lagging, and electric heat tracing cables are applied to exposed piping lines. Blowers and control panels are housed in insulated enclosures.

Q: What civil engineering work is required on-site prior to delivery?

A: The site requires a leveled, load-bearing concrete foundation slab matching the footprint of the package skid, along with pre-laid inlet sewer lines, utility power supply connection points, and treated water discharge outlets.

Q: Is professional installation supervision provided?

A: Yes. Comprehensive English installation manuals, piping schematics, and electrical diagrams are supplied. On-site mechanical and electrical supervision by senior commissioning engineers is available upon request.

Q: How is excess biological sludge managed within the package plant?

A: Excess sludge is periodically transferred via air-lift pumps from the aeration zone into an integrated sludge digestion compartment. The stabilized sludge is then periodically pumped out or routed to an optional mechanical dewatering screw press.

Q: What are the main utility requirements needed to run the plant?

A: The system requires a stable 3-phase electrical power supply matching the total connected motor load, a utility water line for chemical mixing or cleaning, and proper drainage channels for effluent monitoring.
