A multidisciplinary water treatment specialist, Water Purification Chemical & Plant, offers a range of services that encompass the chemical aspects of drinking water treatment, the latest filtration technologies and the design of major water purification plants.
Included in this selection of water treatment services are the design and construction of drinking water plants, which are available in modular, skid-mounted and containerised designs from Water Purification Chemical & Plant (WPCP).“Transforming raw surface water from dams and rivers into pristine drinking water that is safe forms an important part of our business,” explains Martin Overy, WPCP’s managing director.
“The company, with a commitment to the highest quality standards, has made a significant investment in the latest equipment and ongoing research, to ensure optimum efficiency and the total hygiene of every installation. “The water quality of these units conforms to SANS 241:2001 drinking water specifications.”
WPCP’s modular drinking water plants are locally manufactured, using non-corrodible materials to ensure extended service life of the system. Flocculant mixing (velocity coefficients) is designed to suit the water quality of each installation.
Modular drinking water plants encompass an upflow sludge blanket, which is manufactured to exact specifications from UV stabilised reinforced polyester resin or coated mild steel. These modules are available in 6 and 15 m3/h units, with a 45 degree cone for efficient sludge removal. The upflow velocity is between 1.2 and 1.5 m3/h, with a retention period of approximately one hour. Modules with inclined tube settlers have a flow rate between 50 and 160 m3/h.
WPCP manufactures single and/or dual media filter units for the efficient separation of suspended and particulate solids. Advanced dual filtration technology ensures highly efficient filtration capabilities – the high dirt storage capacity of Hydro-Anthrazit and fine filter quality of silica sand combine to ensure high levels of water purity.
Package modules are available in capacities of 1.5, 3, 15, 25 and 50 m3/h. Treatment plants are available in various capacities from 1.5 to 600 m3/h.
Also in WPCP’s range of drinking water plants are skid-mounted units, which are suitable for applications that include small communities, farms and game ranches. These units have capacities between 1 000 and 3 000 ℓ/h, and accommodate a wide range of water conditions, from low to high turbidity. Skid-mounted units have been designed for easy portability. All equipment is secured to a rugged, portable, epoxy coated steel skid.
Containerised drinking water plants, available in capacities from 6 to 24 m3/h, are also designed to handle all water turbidity conditions. Equipment is secured and housed in a newly designed robust 6 m shipping container.
WPCP offers a technical advisory service, as well as maintenance contracts to ensure optimum efficiency, total hygiene and extended service life of each drinking water system. Rental options with a chemical supply are also available.
The company also offers a full analytical service from its in-house laboratories and a full range of flocculants is manufactured at the WPCP factory in Hammarsdale, KwaZulu-Natal. Various forms of disinfection include bromine/chlorine ‘Bromochlor’ tablets via a tablet feeder, ozonation and hydrogen peroxide.
