Common failures & inspection points

Aeration System Functionality - Verify that the air blower operates normally, produces adequate air flow (measured in m³/h), and shows no unusual vibrations or

Operational test of blower unit; visual inspection of diffuser elements; measurement of air delivery pressure and flow rate; check for unusual noise or vibration

Chlorine Disinfection and De-chlorination Chemical System - Verify chlorine dosing pump operational status and output rate (target 5%), monitor de-chlorination

Test chlorine dosing pump capacity and pressure; verify de-chlorination system activation; sampling of effluent for residual chlorine content; inspection of chemical storage and delivery lines

Biofilm Reactor Integrity and Biological Process - Verify that the fixed-film structured matrix is intact, not collapsed or excessively fouled. Monitor tank for

Visual internal inspection of reactor matrix and tank walls; odor assessment; sludge level measurement; microbial activity verification; sediment sampling for COD/BOD parameters

Vacuum/Gravity Feed System and Sewage Inlet Lines - Ensure vacuum unit (if installed) operates at correct pressure range, check all sewage inlet lines for leaks

Pressure gauge reading for vacuum system; visual inspection of all feed lines and connections; pressure/flow testing; valve function verification; check for odor leaks indicating line failures

System Capacity and Load Compliance - Verify that actual crew/passenger count and wastewater generation rates do not exceed the rated P.E. capacity of the insta

Review vessel crew manifest and capacity records; sampling of influent sewage flow rate and BOD5 concentration; comparison with unit design specifications (1.05-4.20 m³/day for STP 2010; 15-100 P.E. for STP 2016)
