High-Performance Sediment Filtration Systems
Engineered and validated by Tradingwise Limited to reduce turbidity (NTU), protect equipment, and extend system service life.
We design, test, and supply sediment filtration systems that remove suspended solids from water supplies. Our solutions are validated through in-house performance testing with continuous turbidity measurement and data logging.
What Tradingwise Does
Tradingwise Limited designs, tests, and supplies sediment filtration systems. These systems are engineered to remove suspended solids, reducing turbidity, protecting equipment, and preventing premature system failure. Our solutions deliver stable performance across the full service life of the filter, not only at start-up.
Validation is conducted through rigorous in-house testing. We measure turbidity pass-through (NTU), total litres processed, pressure behaviour, and service-life consistency under sustained sediment loading conditions, providing transparent, test-based performance data.
We specialize in sediment filtration and turbidity reduction for water treatment applications where reliability and validated performance are essential. Every system is matched to your specific water conditions, flow requirements, and downstream protection needs through our application engineering approach.
The Problems We Solve
High Turbidity (NTU)
Suspended solids increase water turbidity, reducing clarity and compromising the effectiveness of downstream processes like disinfection and purification.
Equipment Damage
Sediment accumulation leads to abrasion, clogging, and accelerated wear in valves, pumps, heat exchangers, and other sensitive process equipment.
Premature Filter Failure
Excessive particulate loading causes rapid differential pressure increase and early exhaustion of filter media, reducing operational lifespan and efficiency.
Inconsistent Water Quality
Fluctuations in sediment loads and suboptimal filtration performance result in variable effluent quality, impacting product consistency and compliance standards.
These challenges are common across residential, commercial, industrial, and municipal water applications. Tradingwise sediment filtration systems address each of these problems through engineered design and validated performance under real operating conditions.
Proven Performance: Test-Based Data
All performance data on this website is based on controlled testing conducted by Tradingwise under documented conditions.
Tradingwise Limited conducts all filtration testing in-house. This process involves continuous measurement and data logging throughout each test period. Performance is evaluated using key metrics including influent and effluent turbidity (NTU), pressure differential across the filter, and total volume processed before defined end-of-life criteria are reached.
Our testing protocols are designed to simulate sustained sediment loading conditions. This verifies filter behavior over their full operational run, providing reliable data for system specification and performance prediction in real-world applications.
Example result: In comparative testing, the TW91 filter processed approximately 3,500 litres before reaching its end-of-life criteria, while maintaining consistent turbidity reduction throughout the test run.
TW91 is a Tradingwise sediment filtration unit evaluated for turbidity reduction and service-life performance under sustained sediment loading

Application variability notice: Results vary depending on inlet water conditions, sediment composition, flow rate, operating pressure, and duty cycle. Performance data should be interpreted within the context of specific application parameters. End-of-life criteria are defined based on measured turbidity breakthrough and operational limits observed during the test run.
NTU vs Volume Processed: Performance Interpretation
This line chart illustrates the filtration performance of the TW91 filter by tracking turbidity (NTU) against the volume of water processed. The blue line represents the consistent inlet NTU, while the orange line indicates the effluent NTU after filtration. To interpret the chart effectively for engineering and procurement planning, observe the following phases:
  1. Initial Performance: At the start of the test run (Volume Processed = 0 Litres), the chart shows the initial reduction in NTU, demonstrating the filter's immediate effectiveness.
  1. Steady-State Operation: For the majority of the operational run, the effluent NTU (green line) remains stable and significantly lower than the inlet NTU. This period represents the filter's consistent, high-efficiency performance under controlled conditions.
  1. Breakthrough and End-of-Life: As the filter approaches its defined end-of-life criteria, a gradual increase in the effluent NTU (green line) indicates "breakthrough." This point signifies when the filter's capacity to remove turbidity is diminishing, guiding replacement schedules.
This data enables informed specification, maintenance planning, and prediction of service life before breakthrough, providing critical insights for filter selection and operational efficiency.
This chart shows typical performance from in-house testing under controlled conditions. Actual field performance will vary based on water chemistry, flow rate, and sediment characteristics.
