Avista Technologies - Multimedia Filtration Products and Services
INCREASE PARTICLE REMOVAL Avista provides membrane compatible coagulants and technical services to increase the efficiency of multimedia filtration (MMF) equipment. Colloids and silt fouling are major causes of performance loss in membrane systems, which is why many system designs include upstream MMF to target particle removal. In addition to MMF products, we also offer lab services, analytical tools, field services and chemical application recommendations to keep MMF equipment in top form.
Avista takes a customized approach to optimizing your MMF system, using a combination of high performance products, lab services and analytical tools.
RoQuest® | COAGULANTS
RoQuest membrane compatible coagulants improve the efficiency of MMF equipment by increasing particulate removal and providing a higher quality feedwater to downstream membrane systems. Adding positively charged RoQuest liquid coagulant to feedwater causes negatively charged particles to form larger particles. The larger particles are more readily retained by MMF equipment, improving the filtrate quality fed to downstream membrane systems. Better quality filtrate can reduce cleaning frequencies and increase system run times. Studies prove that MMF equipment without coagulant addition will remove approximately 35-50% of particulates. A nominal dosage of RoQuest coagulant may allow MMF equipment to remove over 97% of particulates.
