If you are going to purchase a chemical dosing system or water treatment plant and it is to be located at your site, why not purchase the plant already installed in its own building? The benefits are huge, mainly with reduced site installation time and prevention of defects. It makes sense that we can construct the plant at our works and fully factory test it before shipment. No nasty surprises on site, just connect services and switch it on.
Inside the building is a complete sodium hypochlorite storage and dosing system including chemical storage tank with transfer facility, tank bund, by-pass water circulation system so that chlorine can be dosed into this by-pass, chlorine residual analyser with PID controller, electrical control panel, domestic water system with safety shower and eyewash. All safety signs complying with dangerous goods standards and painting of internal walls for chemical resistance are included.
The building mount chlorine dosing system is designed in 3D and fabricated at our workshop with full testing and commissioning. Dioxide Pacific will then attend site to connect services, commission the plant on site and provide operator training.
Dioxide Pacific provided concept process design and obtained approval from the consultant. PACl dosing and multimedia filtration was chosen to flocculate and remove colloidal clay. Chlorine dosing for oxidation of iron and removal of iron oxide with DMI filtration was chosen prior to UV disinfection. Clean water entered a storage tank where it is circulated and dosed with chlorine again to maintain a disinfection residual.
The complete system was installed inside a prefabricated portable building. Chemical storage tanks and bund tanks are located inside the building with vents outside to prevent corrosion. Chemical; dosing pumps are located on top of the tank. All electrical wiring and pipework inside the room was installed and tested prior to delivery. The building was removed from our workshop and delivered to site by truck where it was placed onto blocks ready for connection to site services.
The system is serviced under a preventative maintenance contract by Dioxide Pacific.
In this plant, a small chlorine contact tank is installed in series with the reticulation pipework. Water is circulated from the bottom of the contact tank to the top and sodium hypochlorite is dosed into the circulation loop. Level in the contact tank is maintained with a float valve. The complete system was supplied and installed including contact tank, pumps, dosing pumps, valves, chlorine residual analyser with PID controller, electrical control panel, domestic water system with safety shower and eyewash. All safety signs complying with dangerous goods standards and painting of internal walls for chemical resistance are included.
The plant supplied included excavation and construction of a concrete slab, installation of a plant room shed and installation of chemical dosing equipment inside the shed. Chemical dosing includes duty and standby PACL dosing pumps, electrical control panel, IBC bund storage and diesel generator. As the site is remote and chemical dosing occurs infrequently, power is obtained from a diesel generator.
The complete system was designed, built, installed and commissioned by Dioxide Pacific including all civil, mechanical and electrical works.
There is no limit to the type of chemical dosing or water treatment plant which can be provided in a building or shipping container. For more information on portable building mount chemical dosing systems or to obtain a quotation please press the button at the top of the page.
