WellSpring WaterBoxContainerized Water Treatment Systems

The WellSpring WaterBox water treatment systems are designed to provide clean safe drinking water from virtually any low TDS water source. The system is completely contained inside an ISO shipping container making it easy to move, easy to install, and easy to operate and maintain. The WaterBox can provide from 100,000 to 300,000 gallons per day of clean, safe and fresh drinking water in even the harshest environments. WellSpring units can be deployed, installed and operating in hours instead of days or weeks.

The WellSpring WaterBox includes the following treatment technologies:

Back-washable Filter The Wellspring line incorporates a compressed disc filter system followed by a media filtration system. This combination has proven most effective for removing large suspended particles that would interfere with or reduce the effectiveness of subsequent treatment steps. The filter automatically cleans itself based on differential pressure. Backwash frequency and duration are dependent upon the solids loading of the water source.

Disc Filtration specifications:Disc Material PolypropyleneFiltration grade: 50 micronsBackwash volume: 2.5 gallonsBackwash duration: 10-20 secondsBackwash frequency: 30-60 minutes

Media Filtration specifications:Flux Rate: 5-10 gpm sq. ft.Backwash Rate: 14-18 gpm sq. ft.Backwash duration: 10 minutesBackwash frequency: 12-24 hoursBed Depth: 36-40 inches

Chemical Treatment Chemicals such as ferric chloride, oxidants or coagulants that aid in filtration may be injected to remove particularly challenging contaminants such as iron, algae, or colloidal suspensions. pH adjustment may be required which would allow mechanical separation equipment to operate effectively.

Activated Carbon is used as a pretreatment step to the ultra-filtration system. The activated carbon is added to remove or reduce VOCs, pesticides and herbicides, benzene, tannins, trihalomethanes and inorganic molecules such as radon, chlorine and other man-made chemicals found in water.

Ultra-filtration The ultra-filtration system is a hollow fiber module used to remove all suspended particles larger than 150,000 Daltons molecular weight. The UF membrane is effective at removing bacteria, giardia, and cryptosporidium and provides high quality effluent in a wide range of varying water sources. The ultra-filtration system operates in either the dead-end or cross-flow manner depending upon the solids loading and the nature of the contaminants. The backwash is chemically enhanced with chlorine to remove biological material.
