The sludge resulting from this process represents the next challenge for the water treatment industry, in particular the minimizing of its volume. This Sludge Dewatering handbook will present the key parameters to take into account in order to optimi-ze sludge treatment with SNF Floerger’s organic polymers.
We supply water treatment chemicals; coating and resin additives; specialty acrylic monomers; consumer additives; plus a broad range of dispersants, surfactants, and other additives for the concrete admixtures, synthetic rubber polymerization, gypsum processing and oil well drilling markets.
Cationic polyacrylamide Polymers organic chemicals PAM. Polyacrylamide, abbr. PAM. This product is a water- soluble high polymer.It’s not soluble in most organic solvents, with good flocculating activity, and can reduce the friction resistance between liquid.It is widely used in many fileds like Water Treatment, Oil Exploration, Sludge Dewatering, Paper Making, Textile, Sugar Making, Coal
Even within the treatment plant, the unit cost of labor, polymer and electricity is lower in the U.S. than European counterparts, making decisions on cost savings harder to support. Verdict. Biosolids dewatering is a component of public wastewater treatment that is wide open for optimization and significant money-saving efficiencies.
Water Treatment Plant Residuals Dewatering Feasibility Study . ContentsHowever, the City’s WTP raw water quality is so consistently good, and the necessaryThe solids content of dewatered sludge will depend on the dewatering process selected. Table 3 below :
This study compared the dewatering properties of aerobic granular and activated sludge from full-scale wastewater treatment plants, and determined how polymer dose and type affect granular sludge dewatering efficiency. At the same dose, granular sludge filtration cake had about 4% lower humidity than activated sludge cake. Aerobic stabilization improved only activated sludge dewatering.
The magic of polymers. I’ve been working with polymers for more than 25 years. It´s a fascinating chemical that can be used in many water and sludge treatment applications. By improving the efficiency of polymers, we can optimize processes and create value for our customers.

Polyacrylamide in waste water treatment sludge dewatering processing. Main Production: 1. Oilfield Chemicals, Oilfield chemical is a general germ,The oilfield chemicals we can supply include anionic polyacrylamide used for oil drilling mud additives , drag reduction agent and EOR(enhanced oil recovery)agent . 2. Water Treatment Chemicals,Anionic PAM: It is widely used in waste water treatment
SETTLEOMETER: Good for the Determination of Sludge Volume Index (SVI) in Activated Sludge Plants (aka Biological Oxidation Systems) IMHOFF CONE: Good for Determining the Final Sludge Volume of Systems Where the Final Sludge Volume is Less Than 10% of the Initial Volume.
as a flocculant in water treatment and sludge dewatering 13,16effective polymer flooding requires 0.7–1.75 tons of polymer per ton of oil extracted 14 at a concentration(1.5 mg/L Fe 2
secondary treatment), processes intended specifically to accommodate wastewater application to crops, and typical sludge treatment processes. QUANTITY AND QUALITY OF MUNICIPAL WASTEWATER EFFLUENT AND SLUDGE Municipal wastewater represents the spent water supply of communities. In 1990, aver-45
Cost-effective sludge dewatering for independence in sludge disposal. The Q-PRESS® is a screw press with a conical screw shaft and cylindrical sieves consisting of three treatment zones: inlet and drive zone, three-part thickening and dewatering zone, and press zone with pneumatic counter-pressure cone.
floc density and floc size on bound water during polymer conditioning are also discussed. 2. Experimental methods and materials 2.1. Sludge sample and polymer Sludge was obtained from the settling basin at the Chung-Hsien water treatment plant (Taipei, Taiwan). The suspended matter in the surface
A chemical method is provided for the dewatering of biological sludge that has been digested by a thermophilic digestion process. Five versions of the chemical sludge dewatering method are presented. The primary component in the five versions is a polyquaternary amine, preferably of the di-allyl di-methyl ammonium chloride (DADMAC) variety and from the epichlorohydrin di-methyl amine (epi-DMA
As a result, the piston height decreased abruptly again, and the piston came into contact with the filtered cake. Thereafter, the expression started. As the copolymerizing ratio of DMAPAA increased, the dewatering rate increased, which suggests that the cationic polymer is more effective in dewatering the water treatment sludge.

for a hog manure treatment plant utilizing primary and secondary anaerobic digesters along with a dewatering option. The sludge from secondary digester is 82,000 kg/day @ 15% solids. we are planning to use a cationic polymer, 10lb/ ton DS for dewatering. I am trying to figure out the amount of dilution water I will need for diluting the polymer.
