How does pretreatment assist businesses to manage their water-related business risk?
HS Pretreatment, as referenced here, is based on protecting reverse osmosis (RO) components or components used in other final treatment processes – with the understanding that it can also mean filtration down to a micron level. Microbiological contamination, biofilm growth and solids accumulation cause excessive maintenance issues. Equipment is usually not designed to handle suspended solids and operates far more effectively without this contamination. Incoming water (process water) or wastewater (effluent) treatment with suitable pretreatment reduces business risks associated with the breakdown or maintenance of downstream equipment.
What are the benefits of QFS’s Memcor ultrafiltration (UF) system?
Memcor CPII systems use an innovative assembly that combines the feed, filtrate, air, and waste headers with the membrane housings to form the Memrack array. The integral headers within the Memrack array are designed to optimise flow distribution within the system, delivering greater long-term process stability. Self-supporting Memrack arrays reduce the membrane array footprint by up to 50% compared to previous Memcor system offerings. Memrack arrays also fit inside standard shipping containers, allowing for fast delivery and deployment to virtually any site around the globe.
What other applications, besides RO, is the Memcor UF system used for?
Memcor membranes are offered in pressurised, submerged and membrane bioreactor configurations. Each of these configurations offers an opportunity for a unique application. For example, submerged Memcor CSII modules are ideal for gravity sand filter retrofits, capable of improving the final w ater quality with a 75% reduced footprint. Memcor CP II is ideal for emergency implementation for replacing conventional clarification and filtration in potable water treatment. Memcor MBR B40N modules are used in biological wastewater plants to reduce the biological basins by more than 50% and in the replacement of the settling clarifier.
