Having total control over the manufacture of broad spectrum flocculants has gained a local manufacturer recognition of the Department of health.

Water Purification Chemical & Plant – WPCP – manufactures a range of flocculants at the company’s KwaZulu-Natal facility, which is highly efficient in potable water and waste water treatment.

“The WPCP range of FLOCC flocculants is used for the removal of suspended solids and colour from raw river and dam water and also for sludge dewatering in waste water treatment,” says Martin Overy, managing director, WPCP, multidisciplinary water treatment specialists. “ACH flocculants, with low Iron grade, are also suitable for the paper industry and in the pharmaceutical sector for anti-perspirant manufacture.

“The advantage of manufacturing these flocculants in-house at the company’s production facility in Hammarsdale, is WPCP has complete control over quality standards, according to stringent local and international specifications. This includes approval from the South African Department of National Health and Population Development.”

Aluminium Chlorhydrate (ACH) is used as a primary flocculant in the WPCP FLOCC range and as the key ingredient in flocculant blends.

These user-friendly liquids, which are effective over a wide range of turbidities, eliminate the need for alum or ferric based coagulants and significantly reduce the consumption of alkali aids.

The company manufactures approximately 200 tons of ACH per month and supports this production with a technical advisory and support service throughout the country. Technical experts advise users on dosing, dosing equipment and the use of a streaming current ion analyser. Dosage rates and methods depend on individual applications.

These flocculants are available in 30 kg or 240 kg returnable plastic drums and in 1 ton mini bulk containers.

WPCP also has a full analytical service from its in-house laboratories. Various forms of disinfection include Bromine/Chlorine ‘Bromochlor’ tablets via a tablet feeder, ozonation and hydrogen peroxide.

The company’s range of services encompasses the chemical aspects of drinking water treatment, the latest filtration technologies and the design of major water purification plants.
