    The Effect of the Flocculants PAM and PAC in the Treatment

    In the treatment of the domestic sewage, there are two types of the water flocculants: the PAM (Polyacrylamide) and the PAC (Polyaluminium Chloride).The domestic sewage is the waste water which is directly discharged by the residents in the daily life, the major component is the stool and the washing waste water.

    PAM and PAC are often used in sewage treatment flocculant, PAC belongs to the inorganic coagulant, PAM belong to organic flocculants. In terms of price is higher than the PAM PAC. Two products of different composition, varying nature, no matter what kind of product, we can handle the same kind of sewage. However, with better results.

    PAC and PAM showed relatively low zeta potentials compared with PSBF and LBF. With the increase of pH values, zeta potentials of four coagulants/flocculants decreased because of the increasing anti-ion concentrations (Wu et al., 2016). PAC and PAM became negatively charged when pH was higher than 11 and 10, respectively.

    The optimal dosage of PAM was 0.1 mg/L, and higher concentration of PAM (1 mg/L) might have negative effects on sludge settleability. Flocculants with high molecular weights are usually long enough and contains a sufficient number of free functional groups, which can act as bridges, bringing many suspended solids together and building larger

    It has the best effect on the treatment of neutral or alkaline sewage with thick suspended particles, high concentration, cations with positive charges, and with a PH value of 7-14. Such as iron and steel wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, and other sewage. 2.PAM water treatment.

    Comparing to inorganic flocculants, PAC is suitable for water of broad temperature, and is functional in low temperature water. It reduces less basicity less, so less or no basifier needed. There is fewer salts in water treated with PAC, this is good for high purity water purifying and ion-exchange treatment

    Nonionic Polyacrylamide Flocculant

    Nonionic Flocculants is widely used in industrial wastewater treatment, mineral process, paper making and other industries. What's the Nonionic Polyelectrolyte Flocculation Principle? The nonionic polyacrylamide (PAM) has strong flocculation effect as it has good performance in clarifying & purification, settlement promotion, filtering

    When using PAC you should stop treatment when the pH drops below 5.5 or rises above 8.5. You need to do a lot of monitoring and maintenance. Keep testing for pH and water clarity to understand how your pond or runoff is performing. Don’t just add more floc! Spills of reagents can have significant adverse effects on the receiving environment.

    Cationic PAM: It is very efficient in usage and has high dehydration rate. It is used for the waste water treatment in alcohol factory, monosodium glutamate factory, sugar factory, beverage factory, tanneries, dyeing and other fields. It has a better effect to be used together with inorganic coagulant in particular.

    The use of natural and synthetic polymeric flocculants can be used to generate larger , more stable flocs and may reduce treatment times. This is achieved by bringing dispersed particles together, increasing the effective particle size. Flocculants can be used alone, or in combination with coagulants.
