Ultrafiltration (UF) and Microfiltration (MF)
Pillars:
Ultrafiltration and microfiltration is used in the process of removing large particles like suspended solids, colloidal particles, proteins as well as most bacteria and some viruses from water. This results in a dramatically clearer water with lower turbidity / suspended solids loading and has the benefit of providing excellent pre-treatment for unit operations downstream such as like nano-filtration or reverse osmosis.
Hydranautics HydracapMax products are one the most water-efficient UF systems on the market with a high recovery and small footprint while giving consistent turbidity water quality of <0.1NTU. No backwashes are necessary with the outside in technology using blowers to airscour the fibres when regular cleaning is required. This occurs in both modes of configuration, dead end or cross flow. Supplementary manifold connections have been designed to ensure the simplest and most compact configurations possible with the ability to supply up to 10 000 m³/d in a single shipping container. Even at such high flux configurations the PVDF TIPS technology protects the fibres to minimise fibre breakages. Supporting this product is an online-based software package that can generate an overview design or detailed projections.






Memstar USA is one of the largest manufacturers of PVDF NIPS and PVDF TIPS hollow fibres in the world. They have been chosen to provide solutions for some of the world’s largest MBR’s due to the high levels of product quality and with AR Africa’s help are increasing the usage of containerised and space constrained MBR’s in Africa.
Memstar USA is not only providing solutions for the MBR market but are also providing replacement OUTSIDE to IN ultrafiltration modules. Memstar is producing cost-effective direct replacements and are able to replace the fibres of competitor modules with PVDF TIPS fibres. This has allowed Africa mining and agriculture clients to clean more aggressively while ensuring longer lifetimes of the UF’s than was possible before.

Membrane Bio-Reactors (MBR).
- Largest manufacturer of NIPS & TIPS PVDF fibres in the world as of 2022.
- NIPS PVDF, the cost-effective hollow fibre solution with a pH range of 1 to 11 and 500 000ppm hours of chlorine.
- 3rd Gen TIPS PVDF, the stronger solution with a pH range of 1 to 14 and chlorine tolerance of 1 000 000ppm hours and burst pressure 3 to 4 times that of NIPS PVDF.
- 4th Gen TIPS PVDF , 12 to 16 times the strength of NIPS PVDF fibres resulting in a massive surface area increase possible per footprint unit.
- Used in one of the largest MBR’s in the world (800MLPD, Chengdu).
- High density packing and energy efficient aeration (double stack 3000m2, lower footprint, lower power usage).
