If your plant struggles with changing loads, equipment failures, or daily operation, start with a review of what is happening. Aquenvia develops an improvement scope around the existing process and assets.
Review treatment data, equipment condition, operating practices, and current loading. The first goal is to understand the cause of the problem and identify useful next steps.
Compare repair, replacement, process changes, and expansion against the required outcome. Where practical, sequence works around continued plant operation.
Define a maintenance or operating support arrangement around the plant, staffing, and required service coverage. Visits, consumables, spare parts, and response arrangements are agreed in the scope.
Use our sludge screw press selection guide or filter press buyer guide to prepare dry-solids loading, trial criteria, package boundaries and operating requirements for a retrofit review.
Use the disc-filter selection and quotation guide to check effective area, peak flow, solids upsets, available head, wash-water return, bypass protection and downstream UV or reuse duty before choosing a retrofit.
Use the roots-blower selection and acceptance guide to compare measured airflow, pressure, power and temperature with the diffuser grid, hot-weather inlet conditions, controls and standby requirement before replacing equipment.
Use the secondary-clarifier hydraulic, solids and operating guide to review peak flow, return sludge, settleability, blanket depth, sludge collection, weirs and effluent records before replacing equipment or adding tertiary filtration.
Use the primary-clarifier sizing and operating guide to compare actual peak flow, solids capture, sludge concentration, scum, scraper condition, withdrawal records and tank survey before replacing the mechanism or adding chemicals.
Use the RAS and WAS pump selection guide to separate return and wasting duties, verify solids and flow calculations, develop the system curve and test pumps, controls, flowmeters and standby operation.
Use the submersible sewage pump selection guide to review measured flow and head, the system curve, wet-well levels, solids, screening, controls, valves, lifting and standby operation before selecting a replacement.
Use the dry-installed wastewater pump selection guide to compare measured duty with the system curve, check suction and available NPSH, inspect flood protection, drainage, pipe strain, controls and access before replacing a pump.
Use the progressive cavity pump selection guide to calculate the real sludge flow, compare speed with measured output and check inlet supply, rotor, stator, seals, dry-run protection, pressure trips and downstream interlocks before replacing the pump.
Use the rotary lobe pump selection guide to calculate sludge flow and speed, check solids passage, clearances, wear parts, seals, dry-run and pressure protection, and define measured acceptance before replacing the pump.
Use the filter press feed pump selection guide to compare the measured flow-pressure profile, sludge condition, conditioning, cloth resistance, pump control, trips and complete-cycle acceptance before replacing equipment.
Use the belt filter press selection and operating guide to compare measured hydraulic and solids loading, polymer, belt speed, wash water, tracking, cake, filtrate and operator records before replacing the press.
Use the decanter centrifuge selection and operating guide to compare measured hydraulic and solids loading, sludge and polymer trials, torque, cake, centrate, power, vibration, wear and service records before changing settings or replacing equipment.
Use the gravity sludge thickener selection and operating guide to compare measured solids and hydraulic loading, settling, underflow, supernatant, blanket, rake torque, odour and recycle effects before modifying the tank or mechanism.
Use the rotary drum thickener selection and operating guide to compare measured hydraulic and dry-solids loading, sludge and polymer trials, screen condition, washing, filtrate, thickened sludge, controls and downstream constraints before changing settings or replacing equipment.
Use the gravity belt thickener selection and operating guide to compare measured hydraulic and dry-solids loading, polymer trials, belt area, distribution, tracking, washing, filtrate, discharge and controls before changing settings or replacing equipment.
Use the screw thickener selection and operating guide to compare hydraulic and dry-solids loading, sludge and polymer trials, screen condition, screw speed and torque, washing, filtrate, discharge and controls before changing settings or replacing equipment.
Use the lamella clarifier selection and operating guide to compare measured peak flow, solids, chemistry, distribution, plate fouling, outlet collection, sludge withdrawal and controls before cleaning, modifying or replacing equipment.
Use the mechanical bar-screen selection and operating guide to compare peak flow, clean and blinded hydraulics, debris and screenings records, rake capacity, jams, controls, standby, handling and safe maintenance access before modifying or replacing equipment. For smaller openings, MBR pretreatment, spray or brush cleaning, carryover and wash-water return, use the fine-screen troubleshooting and acceptance guide. For drum-specific feed distribution, active area, basket, seals and reject handling, use the rotary drum screen operating guide. For bent lamellae, bottom obstruction, screenings-carpet release or repeated ragging, use the step-screen operating and maintenance guide. For worn brushes, screw or liner wear, wash faults, repeated jams or poor compaction, use the screw-screen operating and maintenance guide.
Use the static wedge-wire screen selection and operating guide to check effective area, peak loading, feed distribution, slots, blinding, cleaning, screenings handling, safe access and measured acceptance before selecting or replacing a passive screen.
Use the screenings washer and compactor selection guide to check wet mass, loose volume, short-peak feed, washing and dewatering acceptance, drainage return, discharge, odour, controls and safe maintenance before selecting or modifying the handling train.
Use the wastewater grinder and macerator selection guide to review protected equipment, representative solids, clean and loaded hydraulics, cutter duty, bypass, standby, controls, safe maintenance and measured acceptance before adding size reduction.
Use the manual bar-screen selection and operating guide to check clean and blocked hydraulics, measured screenings, cleaning response, safe raking access, isolation, standby and storage before installing or retaining a manually cleaned rack.
Use the vortex grit-removal selection and operating guide to connect measured mineral load, particle duty and full flow range with chamber hydraulics, extraction, washing, civil works, controls, maintenance and measurable acceptance.
Use the aerated grit-chamber selection and operating guide to connect flow range, retention, process air, blower pressure, grease duty, extraction, washing, civil works, controls and measurable acceptance.
Use the grit classifier and washer selection guide to connect measured mineral load and slurry peaks with washing acceptance, return-water duty, bin handling, controls, maintenance and quotation inputs.
