Introduction
Polyacrylamide (PAM) for water treatment can be anionic polyacrylamide (APAM) , cation polyacrylamide (CPAM), and nonionic polyacrylamide(NPAM), which is a most widely used water-soluble polymer. Polyacrylamide has the function of flocculation, filtration, thickening, stabilizing colloid, drag reduction, rheology modifiers, adhesives,film and gel. Polyacrylamide are widely applied in the field of petroleum geology exploration, mineral processing, coal washing, paper making, textile, sugar making, food processing, water treatmentand other industries.
Ruanquan produces APAM, CPAM and NPAM are different molecular weights dry powder and colloidal products. The newly developed low residualmonomer polyacrylamide can be used for drinking water, food processing, to meet the requirements of users.
Characteristics
Polyacrylamide white sand-like powder, water-soluble polymers or polyelectrolytes, its molecular chain containing a certain amount ofpolar groups, so it can absorb solid particles suspended in water, making he bridge between the particles and forming large flocs. It can accelerate the sedimentation of particles in suspension andpromote filtering effects.
Application
1. Use as a flocculant for waste water treatment, coal beneficiation, white water recycling in paper industry, chemical industry andsolid-liquid separation.
2. Use as drilling mud materials additive for oil and geological exploration. Also use as oil pressure fluid to reduce the water andenhanced oil recovery.
3. For textile sizing agents with stable performance, low fabric breakage rate and clean surface.
4. For the paper industry,improving paper wet and dry strength, improving retention rate of fine fibers and fillers.
5. For other industries, such as sugar, food processing industry, synthetic resin coating; civil engineering grouting material watershutoff, gels and mud soil stabilization.
Sewage is the waste water produced by the city offices,schools and residents in daily life. The water generally appears black and smells badly which is because it contains a large number of organics, such as cellulose, starch, sugar and fat proteins,etc. It often contains bacteria and virus and its PH value is mostly neutral. It is better to treat it with anion and PAC. In some cases, we can also use cationic with low ionic degrees and inorganicPAC to deal with it. A ton of water consume 480g PAC and 3g ~ 10g PAM. The COD is generally reduced 100 ~ 200mg / L, which can meet the national standards of emission with follow-up treatmentprocess.
Sludge is the solid part of the sewage whose PH value isgenerally 5.5 to 7.5 with appearance of dark brown and also smelly. It is the thick thing between liquid and solid, which is hard to be separated by natural sedimentation. Sludge is usually treatedby cationic. You can choose the models according to the nature of the mud, generally with neutral ionic degree. The sludge can be pressed directly by the filter press, achieving dewatering. It needsdifferent usage with different solid clay. It is general to use 5 ~ 25g PAM in one ton of sludge.

Henan Runquan Purification Material Co., Ltd is a corporation which integrated with research,manufacture, operation and service. It is focus on developing, manufacture, operation of water purification material and water purification project. Since Runquan Corporation had been found in1998, it was restructuring the joint-stock in 2000, which relyies on continuous innovation, advanced technology, high-quality scientific research, production, management, marketing team andconvenient transportation hub, has developed into a outstanding water purification material enterprises in Henan Province.
Henan Runquan Purification Material Co., Ltd has one chemical polyacrylamide production line with theannual output of 10000 tons; Two front hydrolysis polyacrylamide production lines with the annual output of 3000 tons of anionic, 1000 tons of cationic and 500 tons of nonionic separately; it alsohas a polyaluminium chloride oil furnace drying production line; a spray drying production line with annual output of 60000 tons; and a ferrous sulfate drying production line. Products is well knownand won consistent high praise from customers from the industries such as oil, paper making, chemical industry, coal washing, textile, environmental protection water treatment and other industriesetc.
Henan Runquan Purification Material Co., Ltd is cooperated with many universities and chemical researchinstitutions in China. It has been developed the “Yushui” and “Runquan” brand of flocculant, including the products of polyacrylamide, polyaluminium chloride, polyaluminium chloride iron, alkali typealuminum chloride, ferrous sulfate and other water treatment material products and widely used in drinking water, industrial water, circulating water and wastewater.
Production of polyacrylamide (PAM), polyaluminium chloride (PAC), polyaluminium chloride (PAFC) andferrous sulfate are belong to the state of water treatment recommended products. They are widely used in papermaking wastewater treatment, coal washing sewage treatment, oil field sewage treatment,sewage treatment and various kinds of industrial wastewater. With the strong technical force, sophisticated production equipment, complete detection means and strict quality management, all watertreatment products produced by Henan Runquan Purification Material Co., Ltd are meet the national standards. Zhengzhou Runquan Chemical has full implementation of ISO9002 quality system management in2000.Runquan promises to design the most appropriate sewage treatment products to our users by combining the national standard for sewage treatment.
The sludge produces as a waste product of treatment has a pH value generally between 5.5~7.5. Itsconsistency can range between 1% up to 4% and further dewatering will be required. Sludges are usually treated by cationic polymers prior to use in a thickening device such as a belt press,centrifuge or screw press. The PAM dosage depends will depend on the equipment selected for dewatering and the desired % solids of the sludge.
