A clarifier for attachment with a water treatment facility, the clarifier having inlet means for water coming in from the treatment facility and outlet means for clarified water, and means for removing bottom sludge from the clarification tank. The clarifier is divided into a supply chamber with said inlet means opening thereto, as well as a clarification chamber with said outlet connection
US5593589A - Clarifier
A clarifier for separating suspended solids from waste water to provide clarified water, including a generally rectangular tank for containing waste water to be separated, the tank including generally parallel spaced apart first and second sidewalls, each sidewall having upper and lower sidewall portions, and the tank also including upper and lower regions; a first influent passage extending
Aqueous systems such as municipal and industrial effluents and process waters, swimming pools, and potable water supplies are clarified by immersing in the system a flocculant product comprising a high molecular weight, water soluble, synthetic organic polyelectrolyte flocculating material which has been treated with a water soluble, organic polyhydroxy compound so as to convert the

An aqueous organic or inorganic suspension can be coagulated and then flocculated by flowing it past a shaped body comprising a mixture of water soluble multivalent metal coagulant and a water soluble organic polymeric flocculant in the form of substantially discrete particles. The surface of the shaped body is eroded by the flowing stream to form a solution of the coagulant in which the

- What is polyacrylamide (PAM) used for?
- npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
- How is an anionic polyacrylamide flocculant synthesized?
- In this study, an anionic polyacrylamide flocculant was synthesized by ultrasonic initiated template copolymerization (USTP), using sodium allylsulfonate (SAS) and acrylamide (AM) as monomers, poly diallyl dimethyl ammonium chloride (polyDADMAC) as template, and 2,2′-azobis [2- (2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as initiator.
- What is high molecular weight polyacrylamide (PAM)?
- Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
- Who bought polyacrylamide flocculant?
- Commercial flocculant of polyacrylamide (PAM, MW of 2000–14,000 kDa) was bought from Aladdin Industrial Corporation (Shanghai, China). Anhydrous ethanol and acetone were supplied by Zhenqi Chemical Reagent Co., Ltd (Shanghai, China).
