Application of polyacrylamide flocculation with
Non-ionic polyacrylamide (PAM, Sinopharm, China), with two MWs of 3 × 10 6 and 1 × 10 7 Da (MW data provided by the supplier), was diluted to give a stock solution of 1 g/L. Fresh PAM solutions were prepared every three days. Aluminum sulfate hydrate (alum, Al 2 (SO 4) 3 ·18H 2 O; Bodi, China) was used as a coagulant in this study and the stock alum solution was prepared at a concentration

- How does beckart environmental support industrial wastewater treatment systems?
- We support these systems for life with field service, parts and chemicals. Beckart Environmental designs and manufactures a complete range on industrial wastewater treatment systems. With key components produced in house we eliminate the middle man. Whether you need an entire system or an upgrade to an existing one, we can help!
- Who is beckart environmental?
- Founded in 1978, Beckart Environmental has a lengthy history of serving manufacturing industries ranging from metal finishing to machining, corrugated packaging, flexographic printing, painting, food processing, phosphatizing, plastic recycling, nitril glove manufacturing and stone fabricators.
- Why is treated wastewater important in Saudi Arabia?
- Treated wastewater is considered an essential part of KSA's water resource planning that Saudi Arabia's national water strategy aims to use as a significant supply source of commercial, industrial, and agricultural uses for nonpotable water demands.
- Can a containerized water treatment system decentralize water treatment in Saudi Arabia?
- Saikaly and his team developed a compact, containerized technology to decentralize water treatment for 40% of Saudi households that aren’t directly connected to a sewage system. The technology can treat up to 1,000 equivalent populations’ worth of water and can be placed on tanker trucks.
