Proposed MBR treatment for an unidentified soil-waste stream, subject to source clarification, water analysis and confirmation of reuse requirements.
Project Background
The client-supplied design basis is 100 m³/d with an unspecified soil-waste source and no water analysis or confirmed reuse destination. The design must also establish daily flow variation, operating hours, peak conditions, pollutants, site constraints and whether complete treatment, sludge handling or only membrane equipment is required.
Our Solution
We propose screening, flow equalisation and source-appropriate pretreatment before an MBR biological reactor. The MBR stage provides mixed-liquor solids separation without a conventional clarifier, while chlorine dioxide can disinfect the treated water where validated for the application. A dedicated sludge line will condition and dewater residual solids with a plate-and-frame filter press; the final destination must be based on testing and local requirements. Equipment may also require DAF or lamella clarification if oil, solids or settleable material is significant. MBR suitability, pretreatment, disinfection, storage and sludge reuse remain subject to source identification, water analysis and the intended reuse or discharge standard.
What We Asked First
Please confirm the waste source, intended project use, flow variation and operating schedule, pH, COD, BOD₅, TSS, ammonia, TN, TP, oil, salinity and special pollutants, reuse or discharge requirements, site details, electrical supply and delivery location.
