Beijing Hengju - Polyacrylamides and Coagulants for Oilfield, Wastewater Treatment, Potable Water, Mineral Processing, Sugar and Paper Industries

Beijing Hengju manufactures and supplies speciality water treatment chemicals for oilfield, wastewater treatment, potable water, mineral processing, sugar and paper industries. In addition to a complete range of powder grade polyacrylamides, marketed under the HENGFLOC trade name, our company also supplies polydadmac, polyamine and dicyandiamide type liquid coagulants to cater for all requirements of the industries that we serve.

Founded 15 years ago the company has grown rapidly as a result of its involvement in the Chinese oilfield industry where a variety of our products are currently used to improve the efficiency of oil production.

Ultra high molecular weight flocculants

The HENGFLOC range of anionic, cationic and non-ionic flocculants and coagulants is produced in both Beijing, our company headquarters, and in Shanghai, with a total powder polymer capacity exceeding 50,000t per year. We produce all of our acrylamide requirements utilising microbiological technology to produce high quality crystal acrylamide, which enables our range of ultra high molecular weight polymers to be produced. As a result of these investments in new technology our products are capable of competing with other global suppliers and are now being exported around the globe.

Polyacrylamides and coagulants for the wastewater treatment industry

The HENGFLOC range of polyacrylamides and coagulants are used extensively in the treatment of wastewater from both municipal and industrial wastewater treatment plants.

Polyacrylamides for municipal wastewater treatment

Our products can be used in all solid-liquid separation processes in municipal (sewage) wastewater treatment including primary, activated and digested sludge thickening and dewatering processes.

Flocculants and coagulants for industrial wastewater treatment

The HENGFLOC range of flocculants and coagulants are used extensively in the treatment of wastewater from a wide variety of industrial processes also. These industries include:

• Paper
• Textiles
• Leather
• Petrochemical
• Oilfield
• Chemical
• Food
• Breweries/wineries
• Electroplating
• Pharmaceutical
• Slaughterhouses

Polymers for the oil industry

Beijing Hengju has supplied products to the Chinese oil industry for over 10 years and is the leading supplier of polymers to this industry. All the major Chinese oilfields including Daqing, Shengli, Xinjiang, Henan and Huabei use our products extensively.

The major areas of application of our products are:

• Enhanced oil recovery
• Profile modification
• Drilling fluid additives

Powder polyacrylamides for the paper industry

We manufacture a range of powder polyacrylamides and liquid coagulants for use on the paper machine and the wastewater treatment plant. Our products are suitable for a wide variety of different types of paper production.

The HENGFLOC PG range of retention reagents have been specifically developed to be used as a single retention reagent system. They are also used in combination with a mineral or organic coagulant or in a treatment system together with a microparticle.

The HENGFLOC range of coagulants also finds use in the production of paper. These polyamines and polydadmacs are used generally for the following applications:

• In conjunction with an anionic retention aid providing the cationic charge to enable the dual product system to function correctly
• To neutralise the charge on anionic trash in the water circuit
• As fixing agents therefore controlling the 'stickies' in the coated broke
• In conjunction with AKD and ASA sizes to improve cure rate

For the treatment of white water and wastewaters from the paper process the standard HENGFLOC range of cationic and anionic flocculants can be used for effective treatment. Other applications for our products in the paper industry include anionic dye fixers and formation aids for tissue manufacturing.

Polyacrylamides for the potable water treatment industry

Today the potable water industry uses polyacrylamides, polyamines and polydadmacs in clarifying and dewatering processes. The advantages of the organic coagulants against the inorganics are as follows:

• Improved performance at dosages of 5 to 10 times lower
• Minimises the volume of sludge generated thus saving on sludge dewatering costs
• Improvements in solid-liquid separation times therefore demanding less thickening capacity and reduced capital investment
• No effect on the PH of the treated water
• Operates over a broader PH range
• No addition of soluble metals such as Al and Fe

Our HENGFLOC WG range of flocculants and coagulants comply with global requirements for safe use in potable water and food industries and offer cost effective alternatives to the use of inorganic chemical treatment.

Flocculants and coagulants for the sugar industry

The HENGFLOC WG range of flocculants and coagulants comply with global standards for safe use in the food industry and are now extensively used throughout the world.

HENGFLOC WG flocculants are effective for the clarification of sugar juice and our polyamine coagulants, HENGFLOC 110 and 111, are effective in decolouring clarified liquor during both the processing and refining of the sugar juice.
